Preface (part 3)

The camp was now occupied in making the necessary preparations for our homeward journey, which, though homeward, contemplated a new route, and a great circuit to the south and southeast, and the exploration of the Great Basin between the Rocky mountains and the Sierra Nevada. Three principal objects were indicated, by report or by maps, as being on this route; the character or existence of which I wished to ascertain and which I assumed as landmarks, or leading points, on their projected line of return. The first of those points was the Tlamath lake, on the table-land between the head of Fall river, which comes to the Columbia, and the Sacramento, which goes to the Bay of San Francisco; and from which lake a river of the same name makes its way westwardly direct to the ocean. This lake and river are often called Klamet, but I have chosen to write its name according to the Indian pronunciation. The position of this lake, on the line of inland communication between Oregon and California; its proximity to the demarcation boundary of latitude 42°; its imputed double character of lake, or meadow, according to the season of the year; and the hostile and warlike character attributed to the Indians about it--all made it a desirable object to visit and examine. From this lake our course was intended to be about southeast, to a reported lake called Mary's, at some days' journey in the Great Basin; and thence, still on southeast, to the reputed Buenaventura river, which has had a place in so many maps, and countenanced the belief of the existence of a great river flowing from the Rocky mountains to the Bay of San Francisco. From the Buenaventura the next point was intended to be in that section of the Rocky mountains which includes the heads of Arkansas river, and of the opposite waters of the Californian gulf; and thence down the Arkansas to Bent's fort, and home. This was our projected line of return--a great part of it absolutely new to geographical, botanical, and geological science--and the subject of reports in relation to lakes, rivers, deserts, and savages hardly above the condition of mere wild animals, which inflamed desire to know what this terra incognita really contained.

It was a serious enterprise, at the commencement of winter, to undertake the traverse of such a region, and with a party consisting only of twenty- five persons, and they of many nations--American, French, German, Canadian, Indian, and colored--and most of those young, several being under twenty-one years of age. All knew that a strange country was to be explored, and dangers and hardships to be encountered; but no one blenched at the prospect. On the contrary, courage and confidence animated the whole party. Cheerfulness, readiness, subordination, prompt obedience, characterized all; nor did any extremity of peril and privation, to which we were afterwards exposed, ever belie, or derogate from, the fine spirit of this brave and generous commencement. The course of the narrative will show at what point, and for what reasons, we were prevented from the complete execution of this plan, after having made considerable progress upon it, and how we were forced by desert plains and mountain ranges, and deep snows, far to the south, and near to the Pacific ocean, and along the western base of the Sierra Nevada, where, indeed, a new and ample field of exploration opened itself before us. For the present, we must follow the narrative, which will first lead us south along the valley of Fall river, and the eastern base of the Cascade range, to the Tlamath lake, from which, or its margin, three rivers go in three directions--one west, to the ocean; another north, to the Columbia; the third south, to California.

For the support of the party, I had provided at Vancouver a supply of provisions for not less than three months, consisting principally of flour, peas, and tallow--the latter being used in cooking; and, in addition to this, I had purchased at the mission some California cattle, which were to be driven on the hoof. We had 104 mules and horses--part of the latter procured from the Indians about the mission; and for the sustenance of which, our reliance was upon the grass which we should find, and the soft porous wood which was to be substituted when there was none.

Mr. Fitzpatrick, with Mr. Talbot and the remainder of the party, arrived on the 21st; and the camp was now closely engaged in the labor of preparation. Mr. Perkins succeeded in obtaining as a guide to the Tlamath lake two Indians--one of whom had been there, and bore the marks of several wounds he had received from some of the Indians in the neighborhood; and the other went along for company. In order to enable us to obtain horses, he dispatched messengers to the various Indian villages in the neighborhood, informing them that we were desirous to purchase, and appointing a day for them to bring them in.

We made, in the mean time, several excursions in the vicinity. Mr. Perkins walked with Mr. Preuss and myself to the heights, about nine miles distant, on the opposite side of the river, whence, in fine weather, an extensive view may be had over the mountains, including seven great peaks of the Cascade range; but clouds, on this occasion, destroyed the anticipated pleasure, and we obtained bearings only to three that were visible--Mount Regnier, St. Helens, and Mount Hood. On the heights, about one mile south of the mission, a very fine view may be had of Mount Hood and St. Helens. In order to determine their position with as much accuracy as possible, the angular distances of the peaks were measured with the sextant, at different fixed points from which they could be seen.

The Indians brought in their horses at the appointed time, and we succeeded in obtaining a number in exchange for goods; but they were relatively much higher here, where goods are plenty and at moderate prices, than we had found them in the more eastern part of our voyage. Several of the Indians inquired very anxiously to know if we had any dollars; and the horses we procured were much fewer in number than I had desired, and of thin, inferior quality; the oldest and poorest being those that were sold to us. These horses, as ever in our journey you will have occasion to remark, are valuable for hardihood and great endurance.

24th.--At this place one of the men was discharged; and at the request of Mr. Perkins, a Chinook Indian, a lad of nineteen, who was extremely desirous to "see the whites," and make some acquaintance with our institutions, was received into the party under my special charge, with the understanding that I would again return him to his friends. He had lived for some time in the household of Mr. Perkins, and spoke a few words of the English language.

25th.--We were all up early, in the excitement of turning towards home. The stars were brilliant, and the morning cold, the thermometer at daylight 26°.

Our preparations had been fully completed, and to-day we commenced our journey. The little wagon which had hitherto carried the instruments, I judged it necessary to abandon; and it was accordingly presented to the mission. In all our long traveling, it had never been overturned or injured by any accident of the road; and the only things broken were the glass lamps, and one of the front panels, which had been kicked out by an unruly Indian horse. The howitzer was the only wheeled carriage now remaining. We started about noon, when the weather had become disagreeably cold, with flurries of snow. Our friend Mr. Perkins, whose kindness had been active and efficient during our stay, accompanied us several miles on our road, when he bade us farewell, and consigned us to the care of our guides. Ascending to the uplands beyond the southern fork of the Tinanens creek, we found the snow lying on the ground in frequent patches, although the pasture appeared good, and the new short grass was fresh and green. We traveled over high, hilly land, and encamped on a little branch of Tinanens creek, where there were good grass and timber. The southern bank was covered with snow, which was scattered over the bottom; and the little creek, its borders lined with ice, had a chilly and wintry look. A number of Indians had accompanied us so far on our road, and remained with us during the night. Two bad-looking fellows, who were detected in stealing, were tied and laid before the fire, and guard mounted over them during the night. The night was cold, and partially clear.

26th.--The morning was cloudy and misty, and but a few stars visible. During the night water froze in the tents, and at sunrise the thermometer was at 20°. Left camp at 10 o'clock, the road leading along tributaries of the Tinanens, and being, so far, very good. We turned to the right at the fork of the trail, ascending by a steep ascent along a spur to the dividing grounds between this stream and the waters of Fall river. The creeks we had passed were timbered principally with oak and other deciduous trees. Snow lies everywhere here on the ground, and we had a slight fall during the morning; but towards noon the bright sky yielded to a bright sun.

This morning we had a grand view of St. Helens and Regnier: the latter appeared of a conical form, and very lofty, leading the eye far up into the sky. The line of the timbered country is very distinctly marked here, the bare hills making with it a remarkable contrast. The summit of the ridge commanded a fine view of the Taih prairie, and the stream running through it, which is a tributary to the Fall river, the chasm of which is visible to the right. A steep descent of a mountain hill brought us down into the valley, and we encamped on the stream after dark, guided by the light of fires, which some naked Indians, belonging to a village on the opposite side, were kindling for us on the bank. This is a large branch of the Fall river. There was a broad band of thick ice some fifteen feet wide on either bank, and the river current is swift and bold. The night was cold and clear, and we made our astronomical observation this evening with the thermometer at 20°.

In anticipation of coming hardship, and to spare our horses, there was much walking done to-day; and Mr. Fitzpatrick and myself made the day's journey on foot. Somewhere near the mouth of this stream are the falls from which the river takes its name.

27th.--A fine view of Mount Hood this morning; a rose-colored mass of snow, bearing S. 85° W. by compass. The sky is clear, and the air cold; the thermometer 2.5° below zero, the trees and bushes glittering white, and the rapid stream filled with floating ice.

Stiletsi and the White Crane, two Indian chiefs who had accompanied us thus far, took their leave, and we resumed our journey at 10 o'clock. We ascended by a steep hill from the river bottom, which is sandy, to a volcanic plain, around which lofty hills sweep in a regular form. It is cut up by gullies of basaltic rock, escarpments of which appear everywhere in the hills. This plain is called the Taih prairie, and is sprinkled with some scattered pines. The country is now far more interesting to a traveler than the route along the Snake and Columbia rivers. To our right we had always the mountains, from the midst of whose dark pine forests the isolated snowy peaks were looking out like giants. They served us for grand beacons to show the rate at which we advanced in our journey. Mount Hood was already becoming an old acquaintance, and, when we ascended the prairie, we obtained a bearing to Mount Jefferson, S. 23° W. The Indian superstition has peopled these lofty peaks with evil spirits, and they have never yet known the tread of a human foot. Sternly drawn against the sky, they look so high and steep, so snowy and rocky, that it appears almost impossible to climb them; but still a trial would have its attractions for the adventurous traveler. A small trail takes off through the prairie, towards a low point in the range, and perhaps there is here a pass into the Wahlamette valley. Crossing the plain, we descended by a rocky hill into the bed of a tributary of Fall river, and made an early encampment. The water was in holes, and frozen over; and we were obliged to cut through the ice for the animals to drink. An ox, which was rather troublesome to drive, was killed here for food.

The evening was fine, the sky being very clear, and I obtained an immersion of the third satellite, with a good observation of an emersion of the first; the latter of which gives for the longitude, 121° 02' 43"; the latitude, by observation, being 45° 06' 45". The night was cold--the thermometer during the observations standing at 9°.

28th.--The sky was clear in the morning, but suddenly clouded over, and at sunrise it began to snow, with the thermometer at 18°.

We traversed a broken high country, partly timbered with pine, and about noon crossed a mountainous ridge, in which, from the rock occasionally displayed, the formation consists of compact lava. Frequent tracks of elk were visible in the snow. On our right, in the afternoon, a high plain, partially covered with pine, extended about ten miles, to the foot of the Cascade mountains.

At evening we encamped in a basin narrowly surrounded by rocky hills, after a day's journey of twenty-one miles. The surrounding rocks are either volcanic products, or highly altered by volcanic action, consisting of quartz and reddish-colored silicious masses.

29th.--We emerged from the basin, by a narrow pass, upon a considerable branch of Fall river, running to the eastward through a narrow valley. The trail, descending this stream, brought us to a locality of hot springs, which were on either bank. Those on the left, which were formed into deep handsome basins, would have been delightful baths, if the outer air had not been so keen, the thermometer in these being at 89°. There were others on the opposite side, at the foot of an escarpment, in which the temperature of the water was 134°. These waters deposited around the spring a brecciated mass of quartz and feldspar, much of it of a reddish color.

We crossed the stream here, and ascended again to a high plain, from an elevated point of which we obtained a view of six of the great peaks-- Mount Jefferson, followed to the southward by two others of the same class; and succeeding, at a still greater distance to the southward, were three other lower peaks, clustering together in a branch ridge. These, like the great peaks, were snowy masses, secondary only to them; and, from the best examination our time permitted, we are inclined to believe that the range to which they belong is a branch from the great chain which here bears to the westward. The trail, during the remainder of the day, followed near to the large stream on the left, which was continuously walled in between high rocky banks. We halted for the night on a little by-stream.

30th.--Our journey to-day was short. Passing over a high plain, on which were scattered cedars, with frequent beds of volcanic rock in fragments interspersed among the grassy grounds, we arrived suddenly on the verge of the steep and rocky descent to the valley of the stream we had been following, and which here ran directly across our path, emerging from the mountains on the right. You will remark that the country is abundantly watered with large streams, which pour down from the neighboring range.

These streams are characterized by the narrow and chasm-like valleys in which they run, generally sunk a thousand feet below the plain. At the verge of this plain, they frequently commence in vertical precipices of basaltic rock, and which leave only casual places at which they can be entered by horses. The road across the country, which would otherwise be very good, is rendered impracticable for wagons by these streams. There is another trail among the mountains, usually followed in the summer, which the snows now compelled us to avoid; and I have reason to believe that this, passing nearer the heads of these streams, would afford a much better road.

At such places, the gun-carriage was unlimbered, and separately descended by hand. Continuing a few miles up the left bank of the river, we encamped early in an open bottom among the pines, a short distance below a lodge of Indians. Here, along the river the bluffs present escarpments seven or eight hundred feet in height, containing strata of a very fine porcelain clay, overlaid, at the height of about five hundred feet, by a massive stratum of compact basalt one hundred feet in thickness, which again is succeeded above by other strata of volcanic rocks. The clay strata are variously colored, some of them very nearly as white as chalk, and very fine-grained. Specimens brought from these have been subjected to microscopical examination by Professor Bailey, of West Point, and are considered by him to constitute one of the most remarkable deposites of fluviatile infusoria on record. While they abound in genera and species which are common in fresh water, but which rarely thrive where the water is even brackish, not one decidedly marine form is to be found among them; and their fresh-water origin is therefore beyond a doubt. It is equally certain that they lived and died at the situation where they were found, as they could scarcely have been transported by running waters without an admixture of sandy particles; from which, however, they are remarkably free. Fossil infusoria of a fresh-water origin had been previously detected by Mr. Bailey, in specimens brought by Mr. James D. Dana from the tertiary formation of Oregon. Most of the species in those specimens differed so much from those now living and known, that he was led to infer that they might belong to extinct species, and considered them also as affording proof of an alteration, in the formation from which they were obtained, of fresh and salt-water deposites, which, common enough in Europe, had not hitherto been noticed in the United States. Coming evidently from a locality entirely different, our specimens show very few species in common with those brought by Mr. Dana, but bear a much closer resemblance to those inhabiting the northeastern states. It is possible that they are from a more recent deposite; but the presence of a few remarkable forms which are common to the two localities renders it more probable that there is no great difference in their age.

I obtained here a good observation of an emersion of the second satellite; but clouds, which rapidly overspread the sky, prevented the usual number of observations. Those which we succeeded in obtaining, are, however, good; and give for the latitude of the place 44° 35' 23", and for the longitude from the satellite 121° 10' 25".

DECEMBER.

1st.--A short distance above our encampment, we crossed the river, which was thickly lined along its banks with ice. In common with all these mountain-streams the water was very clear and the current swift. It was not everywhere fordable, and the water was three or four feet deep at our crossing, and perhaps a hundred feet wide. As was frequently the case at such places, one of the mules got his pack, consisting of sugar, thoroughly wet, and turned into molasses. One of the guides informed me that this was a "salmon-water," and pointed out several ingeniously- contrived places to catch the fish; among the pines in the bottom I saw an immense one, about twelve feet in diameter. A steep ascent from the opposite bank delayed us again; and as, by the information of our guides, grass would soon become very scarce, we encamped on the height of land, in a marshy place among the pines, where there was an abundance of grass. We found here a single Nez Perce family, who had a very handsome horse in their drove, which we endeavored to obtain in exchange for a good cow; but the man "had two hearts," or, rather, he had one and his wife had another: she wanted the cow, but he loved the horse too much to part with it. These people attach great value to cattle, with which they are endeavoring to supply themselves.

2d.--In the first rays of the sun, the mountain peaks this morning presented a beautiful appearance, the snow being entirely covered with a hue of rosy gold. We traveled to-day over a very stony, elevated plain, about which were scattered cedar and pine, and encamped on another branch of Fall river. We were gradually ascending to a more elevated region, which would have been indicated by the rapidly increasing quantities of snow and ice, had we not known it by other means. A mule, which was packed with our cooking-utensils, wandered off among the pines unperceived, and several men were sent back to search for it.

3d.--Leaving Mr. Fitzpatrick with the party, I went ahead with the howitzer and a few men, in order to gain time, as our progress with the gun was necessarily slower. The country continued the same--very stony, with cedar and pine; and we rode on until dark, when we encamped on a hill-side covered with snow, which we used to-night for water, as we were unable to reach any stream.

4th.--Our animals had taken the back track, although a great number were hobbled; and we were consequently delayed until noon. Shortly after we had left this encampment, the mountain trail from the Dalles joined that on which we were traveling. After passing for several miles over an artemisia plain, the trail entered a beautiful pine forest, through which we traveled for several hours; and about 4 o'clock descended into the valley of another large branch, on the bottom of which were spaces of open pines, with occasional meadows of good grass, in one of which we encamped. The stream is very swift and deep, and about 40 feet wide, and nearly half frozen over. Among the timber here, are larches 140 feet high, and over three feet in diameter. We had to-night the rare sight of a lunar rainbow.

5th.--To-day the country was all pine forest, and beautiful weather made our journey delightful. It was too warm at noon for winter clothes; and the snow, which lay everywhere in patches through the forest, was melting rapidly. After a few hours' ride, we came upon a fine stream in the midst of the forest, which proved to be the principal branch of the Fall river. It was occasionally 200 feet wide--sometimes narrowed to 50 feet--the waters very clear, and frequently deep. We ascended along the river, which sometimes presented sheets of foaming cascades--its banks occasionally blackened with masses of scoriated rock--and found a good encampment on the verge of open bottom, which had been an old camping-ground of the Cayuse Indians. A great number of deer-horns were lying about, indicating game in the neighborhood. The timber was uniformly large, some of the pines measuring 22 feet in circumference at the ground, and 12 to 13 feet at six feet above.

In all our journeying, we had never traveled through a country where the rivers were so abounding in falls; and the name of this stream is singularly characteristic. At every place where we come in the neighborhood of the river, is heard the roaring of falls. The rock along the banks of the stream, and the ledge over which it falls, is a scoriated basalt, with a bright metallic fracture. The stream goes over in one clear pitch, succeeded by a foaming cataract of several hundred yards. In a little bottom above the falls, a small stream discharges into an entonnoir, and disappears below.

We made an early encampment, and in the course of the evening Mr. Fitzpatrick joined us here with the lost mule. Our lodge-poles were nearly worn out, and we found here a handsome set, leaning against one of the trees, very white, and cleanly scraped. Had the owners been here, we would have purchased them; but as they were not, we merely left the old ones in their place, with a small quantity of tobacco.

6th.--The morning was frosty and clear. We continued up the stream on undulating forest ground, over which there was scattered much falling timber. We met here a village of Nez Perce Indians, who appeared to be coming down from the mountains, and had with them fine bands of horses. With them were a few Snake Indians of the root-digging species. From the forest we emerged into an open valley ten or twelve miles wide, through which the stream was flowing tranquilly, upwards of two hundred feet broad, with occasional islands, and bordered with fine broad bottoms. Crossing the river, which here issues from a great mountain ridge on the right, we continued up the southern and smaller branch over a level country, consisting of fine meadow-land, alternating with pine forests, and encamped on it early in the evening. A warm sunshine made the day pleasant.

7th.--To-day we had good traveling ground, the trail leading sometimes over rather sandy soils in the pine forest, and sometimes over meadow-land along the stream. The great beauty of the country in summer constantly suggested itself to our imaginations; and even now we found it beautiful, as we rode along these meadows, from half a mile to two miles wide. The rich soil and excellent water, surrounded by noble forests, make a picture that would delight the eye of a farmer.

I observed to-night an occultation of a Geminorum; which, although at the bright limb of the moon, appears to give a very good result, that has been adopted for the longitude. The occultation, observations of satellites, and our position deduced from daily surveys with the compass, agree remarkably well together, and mutually support and strengthen each other. The latitude of the camp is 43° 30' 36"; and longitude, deduced from the occultation, 121° 33' 50".

8th.--To-day we crossed the last branch of the Fall river, issuing, like all the others we had crossed, in a southwesterly direction from the mountains. Our direction was a little east of south, the trail leading constantly through pine forests. The soil was generally bare, consisting, in greater part, of a yellowish-white pumice-stone, producing varieties of magnificent pines, but not a blade of grass; and to-night our horses were obliged to do without food, and use snow for water. These pines are remarkable for the red color of the bolls; and among them occurs a species of which the Indians had informed me when leaving the Dalles. The unusual size of the cone (16 or 18 inches long) had attracted their attention; and they pointed it out to me among the curiosities of the country. They are more remarkable for their large diameter than their height, which usually averages only about 120 feet. The leaflets are short--only two or three inches long, and five in a sheath; the bark of a red color.

9th.--The trail leads always through splendid pine forests. Crossing dividing grounds by a very fine road, we descended very gently towards the south. The weather was pleasant, and we halted late. The soil was very much like that of yesterday; and on the surface of a hill near our encampment, were displayed beds of pumice-stone; but the soil produced no grass, and again the animals fared badly.

10th.--The country began to improve; and about eleven o'clock we reached a spring of cold water on the edge of a savannah, or grassy meadow, which our guides informed us was an arm of the Tlamath lake; and a few miles further we entered upon an extensive meadow, or lake of grass, surrounded by timbered mountains. This was the Tlamath lake. It was a picturesque and beautiful spot, and rendered more attractive to us by the abundant and excellent grass, which our animals, after traveling through pine forests, so much needed; but the broad sheet of water which constitutes a lake was not to be seen. Overlooking it, immediately west, were several snowy knobs, belonging to what we have considered a branch of the Cascade range. A low point, covered with pines, made out into the lake, which afforded us a good place for an encampment, and for the security of our horses, which were guarded in view on the open meadow. The character of courage and hostility attributed to the Indians in this quarter induced more than usual precaution; and, seeing smokes rising from the middle of the lake (or savannah) and along the opposite shores, I directed the howitzer to be fired. It was the first time our guides had seen it discharged; and the bursting of the shell at a distance, which was something like the second fire of the gun, amazed and bewildered them with delight. It inspired them with triumphant feelings; but on the camps at a distance the effect was different, for the smokes in the lake and on the shores immediately disappeared.

The point on which we were encamped forms, with the opposite eastern shore, a narrow neck, connecting the body of the lake with a deep cove or bay which receives the principal affluent stream, and over the greater part of which the water (or rather ice) was at this time dispersed in shallow pools. Among the grass, and scattered over the prairie lake, appeared to be similar marshes. It is simply a shallow basin, which, for a short period at the time of melting snows, is covered with water from the neighboring mountains; but this probably soon runs off, and leaves for the remainder of the year a green savannah, through the midst of which the river Tlamath, which flows to the ocean, winds its way to the outlet on the south-western side.

11th.--No Indians made their appearance, and I determined to pay them a visit. Accordingly the people were gathered together, and we rode out towards the village in the middle of the lake which one of our guides had previously visited. It could not be directly approached, as a large part of the lake appeared a marsh; and there were sheets of ice among the grass on which our horses could not keep their footing. We therefore followed the guide for a considerable distance along the forest; and then turned off towards the village, which we soon began to see was a few large huts, on the tops of which were collected the Indians. When we had arrived within half a mile of the village, two persons were seen advancing to meet us; and, to please the fancy of our guides, we ranged ourselves into a long line, riding abreast, while they galloped ahead to meet the strangers.

We were surprised, on riding up, to find one of them a woman, having never before known a squaw to take any part in the business of war. They were the village chief and his wife, who, in excitement and alarm at the unusual event and appearance, had come out to meet their fate together. The chief was a very prepossessing Indian, with handsome features, and a singularly soft and agreeable voice--so remarkable as to attract general notice.

The huts were grouped together on the bank of the river which, from being spread out in a shallow marsh at the upper end of the lake, was collected here into a single stream. They were large round huts, perhaps 20 feet in diameter, with rounded tops, on which was the door by which they descended into the interior. Within, they were supported by posts and beams.

Almost like plants, these people seem to have adapted themselves to the soil, and to be growing on what the immediate locality afforded. Their only subsistence at the time appeared to be a small fish, great quantities of which, that had been smoked and dried, were suspended on strings about the lodge. Heaps of straw were lying around; and their residence in the midst of grass and rushes had taught them a peculiar skill in converting this material to useful purposes. Their shoes were made of straw or grass, which seemed well adapted for a snowy country; and the women wore on their heads a closely-woven basket, which made a very good cap. Among other things, were party-colored mats about four feet square, which we purchased to lay on the snow under our blankets, and to use for table-cloths.

Numbers of singular-looking dogs, resembling wolves, were sitting on the tops of the huts; and of these we purchased a young one, which, after its birthplace, was named Tlamath. The language spoken by these Indians is different from that of the Shoshonee and Columbia River tribes; and otherwise than by signs they cannot understand each other. They made us comprehend that they were at war with the people who lived to the southward and to the eastward; but I could obtain from them no certain information. The river on which they live enters the Cascade mountains on the western side of the lake, and breaks through them by a passage impracticable for travelers; but over the mountains, to the northward, are passes which present no other obstacle than in the almost impenetrable forests. Unlike any Indians we had previously seen, these wore shells in their noses. We returned to our camp, after remaining here an hour or two, accompanied by a number of Indians.

In order to recruit a little the strength of our animals, and obtain some acquaintance with the locality, we remained here for the remainder of the day. By observation, the latitude of the camp was 42° 56' 51", and the diameter of the lake, or meadow, as has been intimated, about 20 miles. It is a picturesque and beautiful spot, and, under the hand of cultivation, might become a little paradise. Game is found in the forest, timbered and snowy mountains skirt it, and fertility characterizes it. Situated near the heads of three rivers, and on the line of inland communication with California, and near to Indians noted for treachery, it will naturally, in the progress of the settlement of Oregon, become a point for military occupation and settlement.

From Tlamath lake, the further continuation of our voyage assumed a character of discovery and exploration, which, from the Indians here, we could obtain no information to direct, and where the imaginary maps of the country, instead of assisting, exposed us to suffering and defeat. In our journey across the desert, Mary's lake, and the famous Buenaventura river, were two points on which I relied to recruit the animals and repose the party. Forming, agreeably to the best maps in my possession, a connected water-line from the Rocky mountains to the Pacific ocean, I felt no other anxiety than to pass safely across the intervening desert to the banks of the Buenaventura, where, in the softer climate of a more southern latitude, our horses might find grass to sustain them, and ourselves be sheltered from the rigors of winter, and from the inhospitable desert. The guides who had conducted us thus far on our journey were about to return; and I endeavored in vain to obtain others to lead us, even for a few days, in the direction (east) which we wished to go. The chief to whom I applied alleged the want of horses, and the snow on the mountains across which our course would carry us, and the sickness of his family, as reasons for refusing to go with us.

12th.--This morning the camp was thronged with Tlamath Indians from the southeastern shore of the lake; but, knowing the treacherous disposition which is a remarkable characteristic of the Indians south of the Columbia, the camp was kept constantly on its guard. I was not unmindful of the disasters which Smith and other travelers had met with in this country, and therefore was equally vigilant in guarding against treachery and violence.

According to the best information I had been able to obtain from the Indians, in a few days' traveling we should reach another large water, probably a lake, which they indicated exactly in the course we were about to pursue. We struck our tents at 10 o'clock, and crossed the lake in a nearly east direction, where it has the least extension--the breadth of the arm being here only about a mile and a half. There were ponds of ice, with but little grass, for the greater part of the way, and it was difficult to get the pack-animals across, which fell frequently, and could not get up with their loads, unassisted. The morning was very unpleasant, snow falling at intervals in large flakes, and the sky dark. In about two hours we succeeded in getting the animals over; and, after traveling another hour along the eastern shore of the lake, we turned up into a cove where there was a sheltered place among the timber, with good grass, and encamped. The Indians, who had accompanied us so far, returned to their village on the south-eastern shore. Among the pines here, I noticed some five or six feet in diameter.

13th.--The night has been cold; the peaks around the lake gleam out brightly in the morning sun, and the thermometer is at zero. We continued up the hollow formed by a small affluent to the lake, and immediately entered an open pine forest on the mountain. The way here was sometimes obstructed by fallen trees, and the snow was four to twelve inches deep. The mules at the gun pulled heavily, and walking was a little laborious. In the midst of the wood, we heard the sound of galloping horses, and were agreeably surprised by the unexpected arrival of our Tlamath chief with several Indians. He seemed to have found his conduct inhospitable in letting the strangers depart without a guide through the snow, and had come, with a few others, to pilot us a day or two on the way. After traveling in an easterly direction through the forest for about four hours, we reached a considerable stream, with a border of good grass; and here, by the advice of our guides, we encamped. It is about thirty feet wide, and two to four feet deep, the water clear, with some current; and, according to the information of our Indians, is the principal affluent to the lake, and the head-water of the Tlamath river.

A very clear sky enabled me to obtain here to-night good observations, including an emersion of the first satellite of Jupiter, which gave for the long. 121° 20' 42", and for the lat. 42° 51' 26". This emersion coincides remarkably well with the result obtained from an occultation at the encampment of December 7th to 8th, 1843; from which place, the line of our survey gives an easting of 13 miles. The day's journey was 12 miles.

14th.--Our road was over a broad mountain, and we rode seven hours in a thick snow-storm, always through pine forests, when we came down upon the head-waters of another stream, on which there was grass. The snow lay deep on the ground, and only the high swamp-grass appeared above. The Indians were thinly clad, and I had remarked during the day that they suffered from cold. This evening they told me that the snow was getting too deep on the mountain, and I could not induce them to go any farther. The stream we had struck issued from the mountain in an easterly direction, turning to the southward a short distance below; and, drawing its course upon the ground, they made us comprehend that it pursued its way for a long distance in that direction, uniting with many other streams, and gradually becoming a great river. Without the subsequent information, which confirmed the opinion, we became immediately satisfied that this water formed the principal stream of the Sacramento river; and, consequently, that this main affluent of the bay of San Francisco had its source within the limits of the United States, and opposite a tributary to the Columbia, and near the head of the Tlamath river, which goes to the ocean north of 42°, and within the United States.

15th.--A present, consisting of useful goods, afforded much satisfaction to our guides; and, showing them the national flag, I explained that it was a symbol of our nation; and they engaged always to receive it in a friendly manner. The chief pointed out a course, by following which we would arrive at the big water, where no more snow was to be found. Traveling in a direction N. 60° E. by compass, which the Indians informed me would avoid a bad mountain to the right, we crossed the Sacramento where it turned to the southward, and entered a grassy level plain--a smaller Grand Rond; from the lower end of which the river issued into an inviting country of low rolling hills. Crossing a hard-frozen swamp on the farther side of the Rond, we entered again the pine forest, in which very deep snow made our traveling slow and laborious. We were slowly but gradually ascending a mountain; and, after a hard journey of seven hours, we came to some naked places among the timber, where a few tufts of grass showed above the snow, on the side of a hollow; and here we encamped. Our cow, which every day got poorer, was killed here, but the meat was rather tough.

16th.--We traveled this morning through snow about three feet deep, which, being crusted, very much cut the feet of our animals. The mountain still gradually rose; we crossed several spring heads covered with quaking asp; otherwise it was all pine forest. The air was dark with falling snow, which everywhere weighed down the trees. The depths of the forest were profoundly still; and below, we scarcely felt a breath of the wind which whirled the snow through their branches. I found that it required some exertion of constancy to adhere steadily to one course through the woods, when we were uncertain how far the forest extended, or what lay beyond; and, on account of our animals, it would be bad to spend another night on the mountain. Towards noon the forest looked clear ahead, appearing suddenly to terminate; and beyond a certain point we could see no trees. Riding rapidly ahead to this spot, we found ourselves on the verge of a vertical and rocky wall of the mountain. At our feet--more than a thousand feet below--we looked into a green prairie country, in which a beautiful lake, some twenty miles in length, was spread along the foot of the mountains, its shores bordered with green grass. Just then the sun broke out among the clouds, and illuminated the country below; while around us the storm raged fiercely. Not a particle of ice was to be seen on the lake, or snow on its borders, and all was like summer or spring. The glow of the sun in the valley below brightened up our hearts with sudden pleasure; and we made the woods ring with joyful shouts to those behind; and gradually, as each came up, he stopped to enjoy the unexpected scene. Shivering on snow three feet deep, and stiffening in a cold north wind, we exclaimed at once that the names of Summer Lake and Winter Ridge should be applied to these two proximate places of such sudden and violent contrast.

We were now immediately on the verge of the forest land, in which we had been traveling so many days; and, looking forward to the east, scarce a tree was to be seen. Viewed from our elevation, the face of the country exhibited only rocks and grass, and presented a region in which the artemisia became the principal wood, furnishing to its scattered inhabitants fuel for their fires, building material for their huts, and shelter for the small game which ministers to their hunger and nakedness. Broadly marked by the boundary at the mountain wall, and immediately below us, were the first waters of that Great Interior Basin which has the Wahsatch and Bear River mountains for its eastern, and the Sierra Nevada for its western rim; and the edge of which we had entered upwards of three months before, at the Great Salt Lake.

When we had sufficiently admired the scene below, we began to think about descending, which here was impossible, and we turned towards the north, traveling always along the rocky wall. We continued on for four or five miles, making ineffectual attempts at several places; and at length succeeded in getting down at one which was extremely difficult of descent. Night had closed in before the foremost reached the bottom, and it was dark before we all found ourselves together in the valley. There were three or four half-dead dry cedar-trees on the shore, and those who first arrived kindled bright fires to light on the others. One of the mules rolled over and over two or three hundred feet into a ravine, but recovered himself without any other injury than to his pack; and the howitzer was left midway the mountain until morning. By observation, the latitude of this encampment is 42° 57' 22". It delayed us until near noon the next day to recover ourselves and put every thing in order; and we made only a short camp along the western shore of the lake, which, in the summer temperature we enjoyed to-day, justified the name we had given it. Our course would have taken us to the other shore, and over the highlands beyond; but I distrusted the appearance of the country, and decided to follow a plainly-beaten Indian trail leading along this side of the lake. We were now in a country where the scarcity of water and of grass makes traveling dangerous, and great caution was necessary.

18th.--We continued on the trail along the narrow strip of land between the lake and the high rocky wall, from which we had looked down two days before. Almost every half mile we crossed a little spring, or stream of pure cold water, and the grass was certainly as fresh and green as in the early spring. From the white efflorescence along the shore of the lake, we were enabled to judge that the water was impure, like that of lakes we subsequently found, but the mud prevented us from approaching it. We encamped near the eastern point of the lake, where there appeared between the hills a broad and low connecting hollow with the country beyond. From a rocky hill in the rear, I could see, marked out by a line of yellow dried grass, the bed of a stream, which probably connected the lake with other waters in the spring.

The observed latitude of this encampment is 42° 42' 37".

19th.--After two hours' ride in an easterly direction, through a low country, the high ridge with pine forest still to our right, and a rocky and bald but lower one on the left, we reached a considerable fresh-water stream, which issues from the piny mountains. So far as we had been able to judge, between this stream and the lake we had crossed dividing grounds, and there did not appear to be any connection, as might be inferred from the impure condition of the lake water.

The rapid stream of pure water, roaring along between banks overhung with aspens and willows, was a refreshing and unexpected sight; and we followed down the course of the stream, which brought us soon into a marsh, or dry lake, formed by the expanding waters of the stream. It was covered with high reeds and rushes, and large patches of ground had been turned up by the squaws in digging for roots, as if a farmer had been preparing the land for grain. I could not succeed in finding the plant for which they had been digging. There were frequent trails, and fresh tracks of Indians; and, from the abundant signs visible, the black-tailed hare appears to be numerous here. It was evident that, in other seasons, this place was a sheet of water. Crossing this marsh towards the eastern hills, and passing over a bordering plain of heavy sands, covered with artemisia, we encamped before sundown on the creek, which here was very small, having lost its water in the marshy grounds. We found here tolerably good grass. The wind to-night was high, and we had no longer our huge pine fires, but were driven to our old resource of small dried willows and artemisia. About 12 miles ahead, the valley appears to be closed in by a high, dark-looking ridge.

20th.--Traveling for a few hours down the stream this morning, we turned the point of a hill on our left, and came suddenly in sight of another and much larger lake, which, along its eastern shore, was closely bordered by the high black ridge which walled it in by a precipitous face on this side. Throughout this region the face of the country is characterized by these precipices of black volcanic rock, generally enclosing the valleys of streams, and frequently terminating the hills. Often, in the course of our journey, we would be tempted to continue our road up the gentle ascent of a sloping hill, which, at the summit, would terminate abruptly in a black precipice. Spread out over a length of 20 miles, the lake, when we first came in view, presented a handsome sheet of water, and I gave to it the name of Lake Abert, in honor of the chief of the corps to which I belonged. The fresh-water stream we had followed emptied into the lake by a little fall; and I was doubtful for a moment whether to go on, or encamp at this place. The miry ground in the neighborhood of the lake did not allow us to examine the water conveniently, and, being now on the borders of a desert country, we were moving cautiously. It was, however, still early in the day, and I continued on trusting either that the water would be drinkable or that we should find some little spring from the hill-side. We were following an Indian trail which led along the steep rocky precipice--a black ridge along the western shore holding out no prospect whatever. The white efflorescences which lined the shore like a bank of snow, and the disagreeable odor which filled the air as soon as we came near, informed us too plainly that the water belonged to one of those fetid salt lakes which are common in this region. We continued until late in the evening to work along the rocky shore, but, as often afterwards, the dry, inhospitable rock deceived us; and, halting on the lake, we kindled up fires to guide those who were straggling along behind. We tried the water, but it was impossible to drink it, and most of the people to- night lay down without eating; but some of us, who had always a great reluctance to close the day without supper, dug holes along the shore, and obtained water, which, being filtered, was sufficiently palatable to be used, but still retained much of its nauseating taste. There was very little grass for the animals, the shore being lined with a luxuriant growth of chenopodiaceous shrubs, which burned with a quick bright flame, and made our firewood.

The next morning we had scarcely traveled two hours along the shore, when we reached a place where the mountains made a bay, leaving at their feet a low bottom around the lake. Here we found numerous hillocks covered with rushes, in the midst of which were deep holes, or springs, of pure water; and the bottom was covered with grass, which, although of a salt and unwholesome quality, and mixed with saline efflorescences, was still abundant, and made a good halting-place to recruit our animals, and we accordingly encamped here for the remainder of the day. I rode ahead several miles to ascertain if there was any appearance of a water-course entering the lake, but found none, the hills preserving their dry character, and the shore of the lake sprinkled with the same white powdery substance, and covered with the same shrubs. There were flocks of ducks on the lake, and frequent tracks of Indians along the shore, where the grass had been recently burnt by their fires.

We ascended the bordering mountain, in order to obtain a more perfect view of the lake, in sketching its figure: hills sweep entirely around its basin, from which the waters have no outlet.

22d.--To-day we left this forbidding lake. Impassable rocky ridges barred our progress to the eastward, and I accordingly bore off towards the south, over an extensive sage-plain. At a considerable distance ahead, and a little on our left, was a range of snowy mountains, and the country declined gradually towards the foot of a high and nearer ridge, immediately before us, which presented the feature of black precipices now becoming common to the country. On the summit of the ridge, snow was visible; and there being every indication of a stream at its base, we rode on until after dark, but were unable to reach it, and halted among the sage-bushes on the open plain, without either grass or water. The two India-rubber bags had been filled with water in the morning, which afforded sufficient for the camp; and rain in the night formed pools, which relieved the thirst of the animals. Where we encamped on the bleak sandy plain, the Indians had made huts or circular enclosures, about four feet high and twelve feet broad, of artemisia bushes. Whether these had been forts or houses, or what they had been doing in such a desert place, we could not ascertain.

23d.--The weather is mild; the thermometer at daylight 38°; the wind having been from the southward for several days. The country has a very forbidding appearance, presenting to the eye nothing but sage, and barren ridges. We rode up towards the mountain, along the foot of which we found a lake, that we could not approach on account of the mud; and, passing around its southern end, ascended the slope at the foot of the ridge, where in some hollows we had discovered bushes and small trees--in such situations, a sure sign of water. We found here several springs, and the hill-side was well sprinkled with a species of festuca--a better grass than we had found for many days. Our elevated position gave us a good view over the country, but we discovered nothing very encouraging. Southward, about ten miles distant, was another small lake, towards which a broad trail led along the ridge; and this appearing to afford the most practicable route, I determined to continue our journey in that direction.

24th.--We found the water at the lake tolerably pure, and encamped at the farther end. There were some good grass and canes along the shore, and the vegetables at this place consisted principally of chenopodiaceous shrubs.

25th.--We were roused on Christmas morning by a discharge from the small- arms and howitzer, with which our people saluted the day; and the name of which we bestowed on the lake. It was the first time, perhaps, in this remote and desolate region, in which it had been so commemorated. Always, on days of religious or national commemoration, our voyageurs expect some unusual allowance; and having nothing else, I gave them each a little brandy, (which was carefully guarded, as one of the most useful articles a traveler can carry,) with some coffee and sugar, which here, where every eatable was a luxury, was sufficient to make them a feast. The day was sunny and warm; and resuming our journey, we crossed some slight dividing grounds into a similar basin, walled in on the right by a lofty mountain ridge. The plainly-beaten trail still continued, and occasionally we passed camping-grounds of the Indians, which indicated to me that we were on one of the great thoroughfares of the country. In the afternoon I attempted to travel in a more eastern direction; but after a few laborious miles, was beaten back into the basin by an impassable country. There were fresh Indian tracks about the valley, and last night a horse was stolen. We encamped on the valley bottom, where there was some cream-like water in ponds, colored by a clay soil, and frozen over. Chenopodiaceous shrubs constituted the growth, and made again our firewood. The animals were driven to the hill, where there was tolerably good grass.

26th.--Our general course was again south. The country consists of larger or smaller basins, into which the mountain waters run down, forming small lakes: they present a perfect level, from which the mountains rise immediately and abruptly. Between the successive basins, the dividing grounds are usually very slight; and it is probable that in the seasons of high water, many of these basins are in communication. At such times there is evidently an abundance of water, though now we find scarcely more than the dry beds. On either side, the mountains, though not very high, appear to be rocky and sterile. The basin in which we were traveling declined towards the southwest corner, where the mountains indicated a narrow outlet; and, turning round a rocky point or cape, we continued up a lateral branch valley, in which we encamped at night, on a rapid, pretty little stream of fresh water, which we found unexpectedly among the sage, near the ridge, on the right side of the valley. It was bordered with grassy bottoms and clumps of willows; the water partially frozen. This stream belongs to the basin we had left. By a partial observation to- night, our camp was found to be directly on the 42d parallel. To-night a horse belonging to Carson, one of the best we had in the camp, was stolen by the Indians.

27th.--We continued up the valley of the stream, the principal branch of which here issues from a bed of high mountains. We turned up a branch to the left, and fell into an Indian trail, which conducted us by a good road over open bottoms along the creek, where the snow was five or six inches deep. Gradually ascending, the trail led through a good broad pass in the mountain, where we found the snow about one foot deep. There were some remarkably large cedars in the pass, which were covered with an unusual quantity of frost, which we supposed might possibly indicate the neighborhood of water; and as, in the arbitrary position of Mary's lake, we were already beginning to look for it, this circumstance contributed to our hope of finding it near. Descending from the mountain, we reached another basin, on the flat lake bed of which we found no water, and encamped among the sage on the bordering plain, where the snow was still about one foot deep. Among this the grass was remarkably green, and to- night the animals fared tolerably well.

28th.--The snow being deep, I had determined, if any more horses were stolen, to follow the tracks of the Indians into the mountains, and put a temporary check to their sly operations; but it did not occur again.

Our road this morning lay down a level valley, bordered by steep mountainous ridges, rising very abruptly from the plain. Artemisia was the principal plant, mingled with Fremontia and the chenopodiaceous shrubs. The artemisia was here extremely large, being sometimes a foot in diameter, and eight feet high. Riding quietly along over the snow, we came suddenly upon smokes rising among these bushes; and, galloping up, we found two huts, open at the top, and loosely built of sage, which appeared to have been deserted at the instant; and, looking hastily around, we saw several Indians on the crest of the ridge near by, and several others scrambling up the side. We had come upon them so suddenly, that they had been well-nigh surprised in their lodges. A sage fire was burning in the middle; a few baskets made of straw were lying about, with one or two rabbit-skins; and there was a little grass scattered about, on which they had been lying. "Tabibo--bo!" they shouted from the hills--a word which, in the Snake language, signifies white--and remained looking at us from behind the rocks. Carson and Godey rode towards the hill, but the men ran off like deer. They had been so much pressed, that a woman with two children had dropped behind a sage-bush near the lodge, and when Carson accidentally stumbled upon her, she immediately began screaming in the extremity of fear, and shut her eyes fast to avoid seeing him. She was brought back to the lodge, and we endeavored in vain to open a communication with the men. By dint of presents, and friendly demonstrations, she was brought to calmness; and we found that they belonged to the Snake nation, speaking the language of that people. Eight or ten appeared to live together, under the same little shelter; and they seemed to have no other subsistence than the roots or seeds they might have stored up, and the hares which live in the sage, and which they are enabled to track through the snow, and are very skilful in killing. Their skins afford them a little scanty covering. Herding together among bushes, and crouching almost naked over a little sage fire, using their instinct only to procure food, these may be considered, among human beings, the nearest approach to the animal creation. We have reason to believe that these had never before seen the face of a white man.

The day had been pleasant, but about two o'clock it began to blow; and crossing a slight dividing ground we encamped on the sheltered side of a hill, where there was good bunch-grass, having made a day's journey of 24 miles. The night closed in, threatening snow; but the large sage-bushes made bright fires.

29th.--The morning mild, and at 4 o'clock it commenced snowing. We took our way across a plain, thickly covered with snow, towards a range of hills in the southeast. The sky soon became so dark with snow, that little could be seen of the surrounding country; and we reached the summit of the hills in a heavy snow-storm. On the side we had approached, this had appeared to be only a ridge of low hills and we were surprised to find ourselves on the summit of a bed of broken mountains, which, as far as the weather would permit us to see, declined rapidly to some low country ahead, presenting a dreary and savage character; and for a moment I looked around in doubt on the wild and inhospitable prospect, scarcely knowing what road to take which might conduct us to some place of shelter for the night. Noticing among the hills the head of a grassy hollow, I determined to follow it, in the hope that it would conduct us to a stream. We followed a winding descent for several miles, the hollow gradually broadening into little meadows, and becoming the bed of a stream as we advanced; and towards night we were agreeably surprised by the appearance of a willow grove, where we found a sheltered camp, with water and excellent and abundant grass. The grass, which was covered by the snow on the bottom, was long and green, and the face of the mountain had a more favorable character in its vegetation, being smoother, and covered with good bunch-grass. The snow was deep, and the night very cold. A broad trail had entered the valley from the right, and a short distance below the camp were the tracks where a considerable party of Indians had passed on horseback, who had turned out to the left, apparently with the view of crossing the mountains to the eastward.

30th.--After following the stream for a few hours in a southeasterly direction, it entered a canon where we could not follow; but, determined not to leave the stream, we searched a passage below, where we could regain it, and entered a regular narrow valley. The water had now more the appearance of a flowing creek; several times we passed groves of willows, and we began to feel ourselves out of all difficulty. From our position, it was reasonable to conclude that this stream would find its outlet in Mary's lake, and conduct us into a better country. We had descended rapidly, and here we found very little snow. On both sides, the mountains showed often stupendous and curious-looking rocks, which at several places so narrowed the valley, that scarcely a pass was left for the camp. It was a singular place to travel through--shut up in the earth, a sort of chasm, the little strip of grass under our feet, the rough walls of bare rock on either hand, and the narrow strip of sky above. The grass to-night was abundant, and we encamped in high spirits.

31st.--After an hour's ride this morning, our hopes were once more destroyed. The valley opened out, and before us again lay one of the dry basins. After some search, we discovered a high-water outlet, which brought us in a few miles, and by a descent of several hundred feet, into a long, broad basin, in which we found the bed of the stream, and obtained sufficient water by cutting the ice. The grass on the bottoms was salt and unpalatable.

Here we concluded the year 1843, and our new year's eve was rather a gloomy one. The result of our journey began to be very uncertain; the country was singularly unfavorable to travel; the grasses being frequently of a very unwholesome character, and the hoofs of our animals were so worn and cut by the rocks, that many of them were lame, and could scarcely be got along.

JANUARY.

New Year's day, 1844.--We continued down the valley, between a dry-looking black ridge on the left, and a more snowy and high one on the right. Our road was bad along the bottom, being broken by gullies and impeded by sage, and sandy on the hills, where there is not a blade of grass, nor does any appear on the mountains. The soil in many places consists of a fine powdery sand, covered with a saline efflorescence; and the general character of the country is desert. During the day we directed our course towards a black cape, at the foot of which a column of smoke indicated hot springs.

2d.--We were on the road early. The face of the country was hidden by falling snow. We traveled along the bed of the stream, in some places dry, in others covered with ice; the traveling being very bad, through deep fine sand, rendered tenacious by a mixture of clay. The weather cleared up a little at noon, and we reached the hot springs of which we had seen the vapor the day before. There was a large field of the usual salt grass here, peculiar to such places. The country otherwise is a perfect barren, without a blade of grass, the only plant being some dwarf Fremontias. We passed the rocky cape, a jagged broken point, bare and torn. The rocks are volcanic, and the hills here have a burnt appearance--cinders and coal occasionally appearing as at a blacksmith's forge. We crossed the large dry bed of a muddy lake in a southeasterly direction, and encamped at night, without water and without grass, among sage-bushes covered with snow. The heavy road made several mules give out to-day; and a horse, which had made the journey from the States successfully, thus far, was left on the trail.

3d.--A fog, so dense that we could not see a hundred yards, covered the country, and the men that were sent out after the horses were bewildered and lost; and we were consequently detained at camp until late in the day. Our situation had now become a serious one. We had reached and run over the position where, according to the best maps in my possession, we should have found Mary's lake or river. We were evidently on the verge of the desert which had been reported to us; and the appearance of the country was so forbidding, that I was afraid to enter it, and determined to bear away to the southward, keeping close along the mountains, in the full expectation of reaching the Buenaventura river. This morning I put every man in the camp on foot--myself, of course, among the rest--and in this manner lightened by distribution the loads of the animals. We traveled seven or eight miles along the ridge bordering the valley, and encamped where there were a few bunches of grass on the bed of a hill-torrent, without water. There were some large artemisias; but the principal plants are chenopodiaceous shrubs. The rock composing the mountains is here changed suddenly into white granite. The fog showed the tops of the hills at sunset, and stars enough for observations in the early evening, and then closed over us as before. Latitude by observation, 40° 48' 15".

4th.--The fog to-day was still more dense, and the people again were bewildered. We traveled a few miles around the western point of the ridge, and encamped where there were a few tufts of grass, but no water. Our animals now were in a very alarming state, and there was increased anxiety in the camp.

5th.--Same dense fog continued, and one of the mules died in camp this morning. I have had occasion to remark, on such occasions as these, that animals which are about to die leave the band, and, coming into the camp; lie down about the fires. We moved to a place where there was a little better grass, about two miles distant. Taplin, one of our best men, who had gone out on a scouting excursion, ascended a mountain near by, and to his surprise emerged into a region of bright sunshine, in which the upper parts of the mountain were glowing, while below all was obscured in the darkest fog.

6th.--The fog continued the same, and, with Mr. Preuss and Carson, I ascended the mountain, to sketch the leading features of the country as some indication of our future route, while Mr. Fitzpatrick explored the country below. In a very short distance we had ascended above the mist, but the view obtained was not very gratifying. The fog had partially cleared off from below when we reached the summit; and in the southwest corner of a basin communicating with that in which we had encamped, we saw a lofty column of smoke, 16 miles distant, indicating the presence of hot springs. There, also, appeared to be the outlet of those draining channels of the country; and, as such places afforded always more or less grass, I determined to steer in that direction. The ridge we had ascended appeared to be composed of fragments of white granite. We saw here traces of sheep and antelope.

Entering the neighboring valley, and crossing the bed of another lake, after a hard day's travel over ground of yielding mud and sand, we reached the springs, where we found an abundance of grass, which, though only tolerably good, made this place, with reference to the past, a refreshing and agreeable spot.

This is the most extraordinary locality of hot springs we had met during the journey. The basin of the largest one has a circumference of several hundred feet; but there is at one extremity a circular space of about fifteen feet in diameter, entirely occupied by the boiling water. It boils up at irregular intervals, and with much noise. The water is clear, and the spring deep: a pole about sixteen feet long was easily immersed in the centre; but we had no means of forming a good idea of the depth. It was surrounded on the margin with a border of green grass, and near the shore the temperature of the water was 206°. We had no means of ascertaining that of the centre, where the heat was greatest; but, by dispersing the water with a pole, the temperature at the margin was increased to 208°, and in the centre it was doubtless higher. By driving the pole towards the bottom, the water was made to boil up with increased force and noise. There are several other interesting places, where water and smoke or gas escape; but they would require a long description. The water is impregnated with common salt, but not so much as to render it unfit for general cooking; and a mixture of snow made it pleasant to drink.

In the immediate neighborhood, the valley bottom is covered almost exclusively with chenopodiaceous shrubs, of greater luxuriance, and larger growth, than we have seen them in any preceding part of the journey.

I obtained this evening some astronomical observations.

Our situation now required caution. Including those which gave out from the injured condition of their feet, and those stolen by Indians, we had lost, since leaving the Dalles of the Columbia, fifteen animals; and of these, nine had been left in the last few days. I therefore determined, until we should reach a country of water and vegetation, to feel our way ahead, by having the line of route explored some fifteen or twenty miles in advance, and only to leave a present encampment when the succeeding one was known.

Taking with me Godey and Carson, I made to-day a thorough exploration of the neighboring valleys, and found in a ravine, in the bordering mountains, a good encamping place, where was water in springs, and a sufficient quantity of grass for a night. Overshadowing the springs were some trees of the sweet cottonwood, which, after a long interval of absence, we saw again with pleasure; regarding them as harbingers of a better country. To us, they were eloquent of green prairies and buffalo. We found here a broad and plainly-marked trail, on which there were tracks of horses, and we appeared to have regained one of the thoroughfares which pass by the watering-places of the country. On the western mountains of the valley, with which this of the boiling spring communicates, we remarked scattered cedars--probably indicating that we were on the borders of the timbered region extending to the Pacific. We reached the camp at sunset, after a day's ride of about 40 miles. The horses we rode were in good order, being of some that were kept for emergencies, and rarely used.

Mr. Preuss had ascended one of the mountains, and occupied the day in sketching the country; and Mr. Fitzpatrick had found, a few miles distant, a hollow of excellent grass and pure water, to which the animals were driven, as I remained another day to give them an opportunity to recruit their strength. Indians appear to be everywhere prowling about like wild animals, and there is a fresh trail across the snow in the valley near.

Latitude of the boiling springs, 40° 39' 46".

On the 9th we crossed over to the cottonwood camp. Among the shrubs on the hills were a few bushes of ephedra occidentalis, which afterwards occurred frequently along the road, and, as usual, the lowlands were occupied with artemisia. While the party proceeded to this place, Carson and myself reconnoitred the road in advance, and found another good encampment for the following day.

10th.--We continued our reconnoissance ahead, pursuing a south direction in the basin along the ridge; the camp following slowly after. On a large trail there is never any doubt of finding suitable places for encampments. We reached the end of the basin, where we found, in a hollow of the mountain which enclosed it, an abundance of good bunch-grass. Leaving a signal for the party to encamp, we continued our way up the hollow, intending to see what lay beyond the mountain. The hollow was several miles long, forming a good pass; the snow deepening to about a foot as we neared the summit. Beyond, a defile between the mountains descended rapidly about two thousand feet; and, filling up all the lower space, was a sheet of green water, some twenty miles broad. It broke upon our eyes like the ocean. The neighboring peaks rose high above us, and we ascended one of them to obtain a better view. The waves were curling in the breeze, and their dark-green color showed it to be a body of deep water. For a long time we sat enjoying the view, for we had become fatigued with mountains, and the free expanse of moving waves was very grateful. It was set like a gem in the mountains, which, from our position, seemed to enclose it almost entirely. At the western end it communicated with the line of basins we had left a few days since; and on the opposite side it swept a ridge of snowy mountains, the foot of the great Sierra. Its position at first inclined us to believe it Mary's lake, but the rugged mountains were so entirely discordant with descriptions of its low rushy shores and open country, that we concluded it some unknown body of water, which it afterwards proved to be.

On our road down, the next day, we saw herds of mountain sheep, and encamped on a little stream at the mouth of the defile, about a mile from the margin of the water, to which we hurried down immediately. The water is so slightly salt, that, at first, we thought it fresh, and would be pleasant to drink when no other could be had. The shore was rocky--a handsome beach, which reminded us of the sea. On some large granite boulders that were scattered about the shore, I remarked a coating of calcareous substance, in some places a few inches, and in others a foot in thickness. Near our camp, the hills, which were of primitive rock, were also covered with this substance, which was in too great quantity on the mountains along the shore of the lake to have been deposited by water, and has the appearance of having been spread over the rocks in mass.

Where we had halted appeared to be a favorite camping-place for Indians.

13th.--We followed again a broad Indian trail along the shore of the lake to the southward. For a short space we had room enough in the bottom; but, after traveling a short distance, the water swept the foot of the precipitous mountains, the peaks of which are about 3,000 feet above the lake. The trail wound along the base of these precipices, against which the water dashed below, by a way nearly impracticable for the howitzer. During a greater part of the morning the lake was nearly hid by a snow- storm, and the waves broke on the narrow beach in a long line of foaming serf, five or six feet high. The day was unpleasantly cold, the wind driving the snow sharp against our faces; and, having advanced only about 12 miles, we encamped in a bottom formed by a ravine, covered with good grass, which was fresh and green.

We did not get the howitzer into camp, but were obliged to leave it on the rocks until morning. We saw several flocks of sheep, but did not succeed in killing any. Ducks were riding on the waves, and several large fish were seen. The mountain sides were crusted with the calcareous cement previously mentioned. There were chenopodiaceous and other shrubs along the beach; and, at the foot of the rocks, an abundance of ephedra occidentalis, whose dark-green color makes them evergreens among the shrubby growth of the lake. Towards evening the snow began to fall heavily, and the country had a wintry appearance.

The next morning the snow was rapidly melting under a warm sun. Part of the morning was occupied in bringing up the gun; and, making only nine miles, we encamped on the shore, opposite a very remarkable rock in the lake, which had attracted our attention for many miles. It rose, according to our estimate, 600 feet above the water, and, from the point we viewed it, presented a pretty exact outline of the great pyramid of Cheops. Like other rocks along the shore, it seemed to be incrusted with calcareous cement. This striking feature suggested a name for the lake, and I called it Pyramid Lake; and though it may be deemed by some a fanciful resemblance, I can undertake to say that the future traveler will find much more striking resemblance between this rock and the pyramids of Egypt, than there is between them and the object from which they take their name.

The elevation of this lake above the sea is 4,890 feet, being nearly 700 feet higher than the Great Salt lake, from which it lies nearly west, and distant about eight degrees of longitude. The position and elevation of this lake make it an object of geographical interest. It is the nearest lake to the western rim, as the Great Salt lake is to the eastern rim, of the Great Basin which lies between the base of the Rocky mountains and the Sierra Nevada--and the extent and character of which, its whole circumference and contents, it is so desirable to know.

The last of the cattle which had been driven from the Dalles was killed here for food, and was still in good condition.

15th.--A few poor-looking Indians made their appearance this morning, and we succeeded in getting one into the camp. He was naked, with the exception of a tunic of hare-skins. He told us that there was a river at the end of the lake, but that he lived in the rocks near by. From the few words our people could understand, he spoke a dialect of the Snake language; but we were not able to understand enough to know Whether the river ran in or out, or what was its course; consequently, there still remained a chance that this might be Mary's lake.

Groves of large cottonwood, which we could see at the mouth of the river, indicated that it was a stream of considerable size, and, at all events, we had the pleasure to know that now we were in a country where human beings could live. Accompanied by the Indian, we resumed our road, passing on the way several caves in the rock where there were baskets and reeds, but the people had disappeared. We saw also horse-tracks along the shore.

Early in the afternoon, when we were approaching the groves at the mouth of the river, three or four Indians met us on the trail. We had an explanatory conversation in signs, and then we moved on together towards the village, which the chief said was encamped on the bottom.

Reaching the groves, we found the inlet of a large freshwater stream, and all at once were satisfied that it was neither Mary's river nor the waters of the Sacramento, but that we had discovered a large interior lake, which the Indians informed us had no outlet. It is about 35 miles long, and, by the mark of the water-line along the shore, the spring level is about 12 feet above its present waters. The chief commenced speaking in a loud voice as we approached; and parties of Indians, armed with bows and arrows, issued from the thickets. We selected a strong place for our encampment--a grassy bottom, nearly enclosed by the river, and furnished with abundant firewood. The village, a collection of straw huts, was a few hundred yards higher up. An Indian brought in a large fish to trade, which we had the inexpressible satisfaction to find was a salmon- trout; we gathered round him eagerly. The Indians were amused with our delight, and immediately brought in numbers, so that the camp was soon stocked. Their flavor was excellent--superior, in fact, to that of any fish I have ever known. They were of extraordinary size--about as large as the Columbia River salmon--generally from two to four feet in length. From the information of Mr. Walker, who passed among some lakes lying more to the eastward, this fish is common to the streams of the inland lakes. He subsequently informed me that he had obtained them weighing six pounds when cleaned and the head taken off, which corresponds very well with the size of those obtained at this place. They doubtless formed the subsistence of these people, who hold the fishery in exclusive possession.

I remarked that one of them gave a fish to the Indian we had first seen, which he carried off to his family. To them it was probably a feast; being of the Digger tribe, and having no share in the fishery, living generally on seeds and roots. Although this was a time of the year when the fish have not yet become fat, they were excellent, and we could only imagine what they are at the proper season. These Indians were very fat, and appeared to live an easy and happy life. They crowded into the camp more than was consistent with our safety, retaining always their arms; and, as they made some unsatisfactory demonstrations, they were given to understand that they would not be permitted to come armed into the camp; and strong guards were kept with the horses. Strict vigilance was maintained among the people, and one-third at a time were kept on guard during the night. There is no reason to doubt that these dispositions, uniformly preserved, conducted our party securely through Indians famed for treachery.

In the mean time, such a salmon-trout feast as is seldom seen was going on in our camp; and every variety of manner in which fish could be prepared-- boiled, fried, and roasted in the ashes--was put into requisition; and every few minutes an Indian would be seen running off to spear a fresh one. Whether these Indians had seen whites before, we could not be certain; but they were evidently in communication with others who had, as one of them had some brass buttons, and we noticed several other articles of civilized manufacture. We could obtain from them but little information respecting the country. They made on the ground a drawing of the river, which they represented as issuing from another lake in the mountains three or four days distant, in a direction a little west of south; beyond which, they drew a mountain; and further still, two rivers; on one of which they told us that people like ourselves traveled. Whether they alluded to the settlements on the Sacramento, or to a party from the United States which had crossed the Sierra about three degrees to the southward, a few years since, I am unable to determine.

I tried unsuccessfully to prevail on some of them to guide us for a few days on the road, but they only looked at each other and laughed.

The latitude of our encampment, which may be considered the mouth of the inlet, is 39° 51' 13" by our observations.

16th.--This morning we continued our journey along this beautiful stream, which we naturally called the Salmon Trout river. Large trails led up on either side; the stream was handsomely timbered with large cottonwoods; and the waters were very clear and pure. We were traveling along the mountains of the great Sierra, which rose on our right, covered with snow; but below the temperature was mild and pleasant. We saw a number of dams which the Indians had constructed to catch fish. After having made about 18 miles, we encamped under some large cottonwoods on the river bottom, where there was tolerably good grass.

17th.--This morning we left the river, which here issues from mountains on the west. With every stream I now expected to see the great Buenaventura; and Carson hurried eagerly to search, on every one we reached, for beaver cuttings, which he always maintained we should find only on waters that ran to the Pacific; and the absence of such signs was to him a sure indication that the water had no outlet from the Great Basin. We followed the Indian trail through a tolerably level country, with small sage- bushes, which brought us, after 20 miles' journey, to another large stream, timbered with cottonwood, and flowing also out of the mountains, but running more directly to the eastward.

On the way we surprised a family of Indians in the hills; but the man ran up the mountain with rapidity; and the woman was so terrified, and kept up such a continued screaming, that we could do nothing with her, and were obliged to let her go.

18th.--There were Indian lodges and fish-dams on the stream. There were no beaver cuttings on the river; but below, it turned round to the right; and, hoping that it would prove a branch of the Buenaventura, we followed it down for about three hours, and encamped.

I rode out with Mr. Fitzpatrick and Carson to reconnoitre the country, which had evidently been alarmed by the news of our appearance. This stream joined with the open valley of another to the eastward; but which way the main water ran, it was impossible to tell. Columns of smoke rose over the country at scattered intervals--signals by which the Indians here, as elsewhere, communicate to each other that enemies are in the country. It is a signal of ancient and very universal application among barbarians.

Examining into the condition of the animals when I returned into the camp, I found their feet so much cut up by the rocks, and so many of them lame, that it was evidently impossible that they could cross the country to the Rocky mountains. Every piece of iron that could be used for the purpose had been converted into nails, and we could make no further use of the shoes we had remaining. I therefore determined to abandon my eastern course, and to cross the Sierra Nevada into the valley of the Sacramento, wherever a practicable pass could be found. My decision was heard with joy by the people, and diffused new life throughout the camp.

Latitude, by observation, 39° 24' 16".

19th.--A great number of smokes are still visible this morning, attesting at once the alarm our appearance had spread among these people, and their ignorance of us. If they knew the whites, they would understand that their only object in coming among them- was to trade, which required peace and friendship; but they have nothing to trade--consequently, nothing to attract the white man; hence their fear and flight.

At daybreak we had a heavy snow; but set out, and, returning up the stream, went out of our way in a circuit over a little mountain; and encamped on the same stream, a few miles above, in latitude 39° 19' 21" by observation.

20th.--To-day we continued up the stream, and encamped on it close to the mountains. The freshly fallen snow was covered with the tracks of Indians, who had descended from upper waters, probably called down by the smokes in the plain.

We ascended a peak of the range, which commanded a view of this stream behind the first ridge, where it was winding its course through a somewhat open valley, and I sometimes regret that I did not make the trial to cross here; but while we had fair weather below, the mountains were darkened with falling snow, and, feeling unwilling to encounter them, we turned away again to the southward. In that direction we traveled the next day over a tolerably level country, having always the high mountains on the west. There was but little snow or rock on the ground; and, after having traveled 24 miles, we encamped again on another large stream, running off to the northward and eastward, to meet that we had left. It ran through broad bottoms, having a fine meadow-land appearance.

Latitude 39° 01' 53".

22d.--We traveled up the stream about fourteen miles, to the foot of the mountains, from which one branch issued in the southwest, the other flowing S.S.E. along their base. Leaving camp below, we ascended the range through which the first stream passed, in a canon; on the western side was a circular valley about 15 miles long, through which the stream wound its way, issuing from a gorge in the main mountain, which rose abruptly beyond. The valley looked yellow with faded grass; and the trail we had followed was visible, making towards the gorge, and this was evidently a pass; but again, while all was bright sunshine on the ridge and on the valley where we were, the snow was falling heavily in the mountains. I determined go still to the southward, and encamped on the stream near the forks, the animals being fatigued and the grass tolerably good.

The rock of the ridge we had ascended is a compact lava, assuming a granitic appearance and structure, and containing, in some places, small nodules of obsidian. So far as composition and aspect are concerned, the rock in other parts of the ridge appears to be granite; but it is probable that this is only a compact form of lava of recent origin.

By observation, the elevation of the encampment was 5,020 feet; and the latitude 38° 49' 54".

23d.--We moved along the course of the other branch towards the southeast, the country affording a fine road; and, passing some slight dividing- grounds, descended towards the valley of another stream. There was a somewhat rough-looking mountain ahead, which it appeared to issue from, or to enter--we could not tell which; and as the course of the valley and the inclination of the ground had a favorable direction, we were sanguine to find here a branch of the Buenaventura; but were again disappointed, finding it an inland water, on which we encamped after a day's journey of 24 miles. It was evident that, from the time we descended into the plain at Summer lake, we had been flanking the great range of mountains which divided the Great Basin from the waters of the Pacific; and that the continued succession, and almost connection, of lakes and rivers which we encountered, were the drainings of that range. Its rains, springs, and snows, would sufficiently account for these lakes and streams, numerous as they were.

24th.--A man was discovered running towards the camp as we were about to start this morning, who proved to be an Indian of rather advanced age--a sort of forlorn hope, who seemed to have been worked up into the resolution of visiting the strangers who were passing through the country. He seized the hand of the first man he met as he came up, out of breath, and held on, as if to assure himself of protection. He brought with him, in a little skin bag, a few pounds of the seeds of a pine-tree, which to- day we saw for the first time, and which Dr. Torrey has described as a new species, under the name of pinus monophyllus; in popular language it might be called the nut pine. We purchased them all from him. The nut is oily, of very agreeable flavor, and must be very nutritious, as it constitutes the principal subsistence of the tribes among which we were now traveling. By a present of scarlet cloth, and other striking articles, we prevailed upon this man to be our guide of two days' journey. As clearly as possible by signs, we made him understand our object; and he engaged to conduct us in sight of a good pass which he knew. Here we ceased to hear the Shoshonee language--that of this man being perfectly unintelligible. Several Indians, who had been waiting to see what reception he would meet with, now came into camp; and, accompanied by the new-comers, we resumed our journey.

The road led us up the creek, which here becomes a rather rapid mountain stream, fifty feet wide, between dark-looking hills without snow; but immediately beyond them rose snowy mountains on either side, timbered principally with the nut pine. On the lower grounds, the general height of this tree is twelve to twenty feet, and eight inches the greatest diameter; it is rather branching, and has a peculiar and singular, but pleasant odor. We followed the river for only a short distance along a rocky trail, and crossed it at a dam which the Indians made us comprehend had been built to catch salmon trout. The snow and ice were heaped up against it three or four feet deep entirely across the stream.

Leaving here the stream, which runs through impassable canons, we continued our road over a very broken country, passing through a low gap between the snowy mountains. The rock which occurs immediately in the pass has the appearance of impure sandstone, containing scales of black mica. This may be only a stratified lava. On issuing from the gap, the compact lava, and other volcanic products usual in the country, again occurred. We descended from the gap into a wide valley, or rather basin, and encamped on a small tributary to the last stream, on which there was very good grass. It was covered with such thick ice, that it required some labor with pickaxes to make holes for the animals to drink. The banks are lightly wooded with willow, and on the upper bottoms are sage and Fremontia, with ephedra occidentalis, which begins to occur more frequently. The day has been a summer one, warm and pleasant; no snow on the trail, which, as we are all on foot, makes traveling more agreeable. The hunters went into a neighboring mountain, but found no game. We have five Indians in camp to-night.

25th.--The morning was cold and bright, and as the sun rose the day became beautiful. A party of twelve Indians came down from the mountains to trade pine nuts, of which each one carried a little bag. These seemed now to be the staple of the country; and whenever we met an Indian, his friendly salutation consisted in offering a few nuts to eat and to trade; their only arms were bows and flint-pointed arrows. It appeared that in almost all the valleys the neighboring bands were at war with each other; and we had some difficulty in prevailing on our guides to accompany us on this day's journey, being at war with the people on the other side of a large snowy mountain which lay before us.

The general level of the country appeared to be getting higher, and we were gradually entering the heart of the mountains. Accompanied by all the Indians, we ascended a long ridge, and reached a pure spring at the edge of the timber, where the Indians had waylaid and killed an antelope, and where the greater part of them left us. Our pacific conduct had quieted their alarms; and though at war among each other, yet all confided in us-- thanks to the combined effects of power and kindness--for our arms inspired respect, and our little presents and good treatment conciliated their confidence. Here we suddenly entered snow six inches deep, and the ground was a little rocky, with volcanic fragments, the mountain appearing to be composed of such rock. The timber consists principally of nut pines, (pinus monophyllus,) which here are of larger size--12 to 15 inches in diameter; heaps of cones lying on the ground, where the Indians have gathered the seeds.

The snow deepened gradually as we advanced. Our guides wore out their moccasins; and putting one of them on a horse, we enjoyed the unusual sight of an Indian who could not ride. He could not even guide the animal, and appeared to have no knowledge of horses. The snow was three or four feet deep on the summit of the, pass; and from this point the guide pointed out our future road, declining to go any further. Below us was a little valley; and beyond this the mountains rose higher still, one ridge above another, presenting a rude and rocky outline. We descended rapidly to the valley: the snow impeded us but little; yet it was dark when we reached the foot of the mountain.

The day had been so warm that our moccasins were wet with melting snow; but here, as soon as the sun begins to decline, the air gets suddenly cold, and we had great difficulty to keep our feet from freezing--our moccasins being frozen perfectly stiff. After a hard day's march of 27 miles, we reached the river some time after dark, and found the snow about a foot deep on the bottom--the river being entirely frozen over. We found a comfortable camp, where there were dry willows abundant, and we soon had blazing fires. A little brandy, which I husbanded with great care, remained, and I do not know any medicine more salutary, or any drink (except coffee) more agreeable, than this in a cold night and after a hard day's march. Mr. Preuss questioned whether the famed nectar ever possessed so exquisite a flavor. All felt it to be a reviving cordial.

The next morning, when the sun had not yet risen over the mountains, the thermometer was at 2° below zero; but the sky was bright and pure, and the weather changed rapidly into a pleasant day of summer. I remained encamped in order to examine the country, and allow the animals a day of rest, the grass being good and abundant under the snow.

The river is fifty or eighty feet wide, with a lively current, and very clear water. It forked a little above our camp, one of its branches coming directly from the south. At its head appeared to be a handsome pass; and from the neighboring heights we could see, beyond, a comparatively low and open country, which was supposed to form the valley of the Buenaventura. The other branch issued from a nearer pass, in a direction S. 75° W., forking at the foot of the mountain, and receiving a part of its waters from a little lake. I was in advance of the camp when our last guides had left us; but, so far as could be understood, this was the pass which they had indicated, and, in company with Carson, to-day I set out to explore it. Entering the range, we continued in a northwesterly direction up the valley, which here bent to the right. It was a pretty open bottom, locked between lofty mountains, which supplied frequent streams as we advanced. On the lower part they were covered with nut-pine trees, and above with masses of pine, which we easily recognised, from the darker color of the foliage. From the fresh trails which occurred frequently during the morning, deer appeared to be remarkably numerous in the mountain.

We had now entirely left the desert country, and were on the verge of a region which, extending westward to the shores of the Pacific, abounds in large game, and is covered with a singular luxuriance of vegetable life.

The little stream grew rapidly smaller, and in about twelve miles we had reached its head, the last water coming immediately out of the mountain on the right; and this spot was selected for our next encampment. The grass showed well in sunny places; but in colder situations the snow was deep, and began to occur in banks, through which the horses found some difficulty in breaking a way.

To the left, the open valley continued in a southwesterly direction, with a scarcely perceptible ascent, forming a beautiful pass, the exploration of which we deferred until the next day, and returned to the camp.

To-day an Indian passed through the valley, on his way into the mountains, where he showed us was his lodge. We comprehended nothing of his language; and, though he appeared to have no fear, passing along in full view of the camp, he was indisposed to hold any communication with us, but showed the way he was going, and pointed for us to go on our road.

By observation, the latitude of this encampment was 38° 18' 01", and the elevation above the sea 6,310 feet.

27th.--Leaving the camp to follow slowly, with directions to Carson to encamp at the place agreed on, Mr. Fitzpatrick and myself continued the reconnoissance. Arriving at the head of the stream, we began to enter the pass--passing occasionally through open groves of large pine-trees, on the warm side of the defile, where the snow had melted away, occasionally exposing a large Indian trail. Continuing along a narrow meadow, we reached, in a few miles, the gate of the pass, where there was a narrow strip of prairie, about 50 yards wide, between walls of granite rock. On either side rose the mountains, forming on the left a rugged mass, or nucleus, wholly covered with deep snow, presenting a glittering and icy surface. At the time, we supposed this to be the point into which they were gathered between the two great rivers, and from which the waters flowed off to the bay. This was the icy and cold side of the pass, and the rays of the sun hardly touched the snow. On the left, the mountains rose into peaks, but they were lower and secondary, and the country had a somewhat more open and lighter character. On the right were several hot springs, which appeared remarkable in such a place. In going through, we felt impressed by the majesty of the mountain, along the huge wall of which we were riding. Here there was no snow; but immediately beyond was a deep bank, through which we dragged our horses with considerable effort. We then immediately struck upon a stream, which gathered itself rapidly, and descended quick; and the valley did not preserve the open character of the other side, appearing below to form a canon. We therefore climbed one of the peaks on the right, leaving our horses below; but we were so much shut up that we did not obtain an extensive view, and what we saw was not very satisfactory, and awakened considerable doubt. The valley of the stream pursued a northwesterly direction, appearing below to turn sharply to the right, beyond which further view was cut off. It was, nevertheless, resolved to continue our road the next day down this valley, which we trusted still would prove that of the middle stream between the two great rivers. Towards the summit of this peak, the fields of snow were four or five feet deep on the northern side; and we saw several large hares, which had on their winter color, being white as the snow around them.

The winter day is short in the mountains, the sun having but a small space of sky to travel over in the visible part above our horizon; and the moment his rays are gone, the air is keenly cold. The interest of our work had detained us long, and it was after nightfall when we reached the camp.

28th.--To-day we went through the pass with all the camp, and, after a hard day's journey of twelve miles, encamped on a high point where the snow had been blown off, and the exposed grass afforded a scanty pasture for the animals. Snow and broken country together made our traveling difficult; we were often compelled to make large circuits, and ascend the highest and most exposed ridges, in order to avoid snow, which in other places was banked up to a great depth.

During the day a few Indians were seen circling around us on snow-shoes, and skimming along like birds; but we could not bring them within speaking distance. Godey, who was a little distance from the camp, had sat down to tie his moccasins, when he heard a low whistle near, and, looking up, saw two Indians half hiding behind a rock about forty yards distant; they would not allow him to approach, but breaking into a laugh, skimmed off over the snow, seeming to have no idea of the power of firearms, and thinking themselves perfectly safe when beyond arm's length.

To-night we did not succeed in getting the howitzer into camp. This was the most laborious day we had yet passed through, the steep ascents and deep snow exhausting both men and animals. Our single chronometer had stopped during the day, and its error in time occasioned the loss of an eclipse of a satellite this evening. It had not preserved the rate with which we started from the Dalles, and this will account for the absence of longitudes along this interval of our journey.

29th.--From this height we could see, at a considerable distance below, yellow spots in the valley, which indicated that there was not much snow. One of these places we expected to reach to-night; and some time being required to bring up the gun, I went ahead with Mr. Fitzpatrick and a few men, leaving the camp to follow, in charge of Mr. Preuss. We followed a trail down a hollow where the Indians had descended, the snow being so deep that we never came near the ground; but this only made our descent the easier, and, when we reached a little affluent to the river, at the bottom, we suddenly found ourselves in presence of eight or ten Indians. They seemed to be watching our motions, and, like the others, at first were indisposed to let us approach, ranging themselves like birds on a fallen log, on the hill-side above our heads, where, being out of our reach, they thought themselves safe. Our friendly demeanor reconciled them, and, when we got near enough, they immediately stretched out to us handfuls of pine-nuts, which seemed an exercise of hospitality. We made them a few presents, and, telling us that their village was a few miles below, they went on to let their people know what we were. The principal stream still running through an impracticable canon, we ascended a very steep hill, which proved afterwards the last and fatal obstacle to our little howitzer, which was finally abandoned at this place. We passed through a small meadow a few miles below, crossing the river, which depth, swift current, and rock, made it difficult to ford; and, after a few more miles of very difficult trail, issued into a larger prairie bottom, at the farther end of which we encamped, in a position rendered strong by rocks and trees. The lower parts of the mountain were covered with the nut-pine. Several Indians appeared on the hill-side, reconnoitring the camp, and were induced to come in; others came in during the afternoon; and in the evening we held a council. The Indians immediately made it clear that the waters on which we were also belonged to the Great Basin, in the edge of which we had been since the 17th of December; and it became evident that we had still the great ridge on the left to cross before we could reach the Pacific waters.

We explained to the Indians that we were endeavoring to find a passage across the mountains into the country of the whites, whom we were going to see; and told them that we wished them to bring us a guide, to whom we would give presents of scarlet cloth, and other articles, which were shown to them. They looked at the reward we offered, and conferred with each other, but pointed to the snow on the mountain, and drew their hands across their necks, and raised them above their heads, to show the depth; and signified that it was impossible for us to get through. They made signs that we must go to the southward, over a pass through a lower range, which they pointed out: there, they said, at the end of one day's travel, we would find people who lived near a pass in the great mountain; and to that point they engaged to furnish us a guide. They appeared to have a confused idea, from report, of whites who lived on the other side of the mountain; and once, they told us, about two years ago, a party of twelve men like ourselves had ascended their river, and crossed to the other waters. They pointed out to us where they had crossed; but then, they said, it was summer time; but now it would be impossible. I believe that this was a party led by Mr. Chiles, one of the only two men whom I know to have passed through the California mountains from the interior of the Basin--Walker being the other; and both were engaged upwards of twenty days, in the summer time, in getting over. Chiles's destination was the bay of San Francisco, to which he descended by the Stanislaus river; and Walker subsequently informed me that, like myself, descending to the southward on a more eastern line, day after day he was searching for the Buenaventura, thinking that he had found it with every new stream, until, like me, he abandoned all idea of its existence, and, turning abruptly to the right, crossed the great chain. These were both western men, animated with the spirit of exploratory enterprise which characterizes that people.

The Indians brought in during the evening an abundant supply of pine-nuts, which we traded from them. When roasted, their pleasant flavor made them an agreeable addition to our now scanty store of provisions, which were reduced to a very low ebb. Our principal stock was in peas, which it is not necessary to say contain scarcely any nutriment. We had still a little flour left, some coffee, and a quantity of sugar, which I reserved as a defence against starvation.

The Indians informed us that at certain seasons they have fish in their waters, which we supposed to be salmon-trout: for the remainder of the year they live upon the pine-nuts, which form their great winter subsistence--a portion being always at hand, shut up in the natural storehouse of the cones. At present, they were presented to us as a whole people living upon this simple vegetable.

The other division of the party did not come in to-night, but encamped in the upper meadow, and arrived the next morning. They had not succeeded in getting the howitzer beyond the place mentioned, and where it had been left by Mr. Preuss, in obedience to my orders; and, in anticipation of the snow-banks and snow-fields still ahead, foreseeing the inevitable detention to which it would subject us, I reluctantly determined to leave it there for the time. It was of the kind invented by the French for the mountain part of their war in Algiers; and the distance it had come with us proved how well it was adapted to its purpose. We left it, to the great sorrow of the whole party, who were grieved to part with a companion which had made the whole distance from St. Louis, and commanded respect for us on some critical occasions, and which might be needed for the same purpose again.

30th.--Our guide, who was a young man, joined us this morning; and, leaving our encampment late in the day, we descended the river, which immediately opened out into a broad valley, furnishing good traveling ground. In a short distance we passed the village, a collection of straw huts; and a few miles below, the guide pointed out the place where the whites had been encamped, before they entered the mountain. With our late start we made but ten miles, and encamped on the low river-bottom, where there was no snow, but a great deal of ice; and we cut piles of long grass to lay under our blankets, and fires were made of large dry willows, groves of which wooded the stream. The river took here a northeasterly direction, and through a spur from the mountains on the left was the gap where we were to pass the next day.

31st.--We took our way over a gently rising ground, the dividing ridge being tolerably low; and traveling easily along a broad trail, in twelve or fourteen miles reached the upper part of the pass, when it began to snow thickly, with very cold weather. The Indians had only the usual scanty covering, and appeared to suffer greatly from the cold. All left us, except our guide. Half hidden by the storm, the mountains looked dreary; and, as night began to approach, the guide showed great reluctance to go forward. I placed him between two rifles, for the way began to be difficult. Traveling a little farther, we struck a ravine, which the Indian said would conduct us to the river; and as the poor fellow suffered greatly, shivering in the snow which fell upon his naked skin, I would not detain him any longer; and he ran off to the mountain, where he said was a hut near by. He had kept the blue and scarlet cloth I had given him tightly rolled up, preferring rather to endure the cold than to get them wet. In the course of the afternoon, one of the men had his foot frostbitten; and about dark we had the satisfaction to reach the bottoms of a stream timbered with large trees, among which we found a sheltered camp, with an abundance of such grass as the season afforded for the animals. We saw before us, in descending from the pass, a great continuous range, along which stretched the valley of the river; the lower parts steep, and dark with pines, while above it was hidden in clouds of snow. This we felt instantly satisfied was the central ridge of the Sierra Nevada, the great California mountain, which only now intervened between us and the waters of the bay. We had made a forced march of 26 miles, and three mules had given out on the road. Up to this point, with the exception of two stolen by Indians, we had lost none of the horses which had been brought from the Columbia river, and a number of these were still strong and in tolerably good order. We had now 67 animals in the band.

We had scarcely lighted our fires, when the camp was crowded with nearly naked Indians; some of them were furnished with long nets in addition to bows, and appeared to have been out on the sage hills to hunt rabbits. These nets were perhaps 30 to 40 feet long, kept upright in the ground by slight sticks at intervals, and were made from a kind of wild hemp, very much resembling in manufacture those common among the Indians of the Sacramento valley. They came among us without any fear, and scattered themselves about the fires, mainly occupied in gratifying their astonishment. I was struck by the singular appearance of a row of about a dozen, who were sitting on their haunches perched on a log near one of the fires, with their quick sharp eyes following every motion.

We gathered together a few of the most intelligent of the Indians, and held this evening an interesting council. I explained to them my intentions. I told them that we had come from a very far country, having been traveling now nearly a year, and that we were desirous simply to go across the mountain into the country of the other whites. There were two who appeared particularly intelligent--one, a somewhat old man. He told me that, before the snows fell, it was six sleeps to the place where the whites lived, but that now it was impossible to cross the mountain on account of the deep snow; and showing us, as the others had done, that it was over our heads, he urged us strongly to follow the course of the river, which he said would conduct us to a lake in which there were many large fish. There, he said, were many people; there was no snow on the ground; and we might remain there until the spring. From their descriptions, we were enabled to judge that we had encamped on the upper water of the Salmon Trout river. It is hardly necessary to say that our communication was only by signs, as we understood nothing of their language; but they spoke, notwithstanding, rapidly and vehemently, explaining what they considered the folly of our intentions, and urging us to go down to the lake. Tah-ve, a word signifying snow, we very soon learned to know, from its frequent repetition. I told him that the men and the horses were strong, that we would break a road through the snow; and spreading before him our bales of scarlet cloth, and trinkets, showed him what we would give for a guide. It was necessary to obtain one, if possible; for I had determined here to attempt the passage of the mountain. Pulling a bunch of grass from the ground, after a short discussion among themselves, the old man made us comprehend, that if we could break through the snow, at the end of three days we would come down upon grass, which he showed us would be about six inches high, and where, the ground was entirely free. So far, he said, he had been in hunting for elk; but beyond that (and he closed his eyes) he had seen nothing; but there was one among them who had been to the whites, and, going out of the lodge, he returned with a young man of very intelligent appearance. Here, said he, is a young man who has seen the whites with his own eyes; and he swore, first by the sky, and then by the ground, that what he said was true. With a large present of goods, we prevailed upon this young man to be our guide, and he acquired among us the name of Melo--a word signifying friend, which they used very frequently. He was thinly clad, and nearly barefoot; his moccasins being about worn out. We gave him skins to make a new pair, and to enable him to perform his undertaking to us. The Indians remained in the camp during the night, and we kept the guide and two others to sleep in the lodge with us--Carson lying across the door, and having made them comprehend the use of our fire arms.

FEBRUARY.

1st.--The snow, which had intermitted in the evening, commenced falling again in the course of the night; and it snowed steadily all day. In the morning I acquainted the men with my decision, and explained to them that necessity required us to make a great effort to clear the mountains. I reminded them of the beautiful valley of the Sacramento, with which they were familiar from the descriptions of Carson, who had been there some fifteen years ago, and who, in our late privations, had delighted us in speaking of its rich pastures and abounding game, and drew a vivid contrast between its summer climate, less than a hundred miles distant, and the falling snow around us. I informed them (and long experience had given them confidence in my observations and good instruments) that almost directly west, and only about 70 miles distant, was the great farming establishment of Captain Sutter--a gentleman who had formerly lived in Missouri, and, emigrating to this country, had become the possessor of a principality. I assured them that, from the heights of the mountain before us, we should doubtless see the valley of the Sacramento river, and with one effort place ourselves again in the midst of plenty. The people received this decision with the cheerful obedience which had always characterized them, and the day was immediately devoted to the preparations necessary to enable us to carry it into effect. Leggins, moccasins, clothing--all were put into the best state to resist the cold. Our guide was not neglected. Extremity of suffering might make him desert; we therefore did the best we could for him. Leggins, moccasins, some articles of clothing, and a large green blanket, in addition to the blue and scarlet cloth, were lavished upon him, and to his great and evident contentment. He arrayed himself in all his colors, and, clad in green, blue, and scarlet, he made a gay-looking Indian; and, with his various presents, was probably richer and better clothed than any of his tribe had ever been before.

I have already said that our provisions were very low; we had neither tallow nor grease of any kind remaining, and the want of salt became one of our greatest privations. The poor dog which had been found in the Bear River valley, and which had been a compagnon de voyage ever since, had now become fat, and the mess to which it belonged, requested permission to kill it. Leave was granted. Spread out on the snow, the meat looked very good; and it made a strengthening meal for the greater part of the camp. Indians brought in two or three rabbits during the day, which were purchased from them.

The river was 40 to 70 feet wide, and now entirely frozen over. It was wooded with large cottonwood, willow, and grain de boeuf. By observation, the latitude of this encampment was 38° 37' 18".

2d.--It had ceased snowing, and this morning the lower air was clear and frosty; and six or seven thousand feet above, the peaks of the Sierra now and then appeared among the rolling clouds, which were rapidly dispersing before the sun. Our Indian shook his head as he pointed to the icy pinnacles, shooting high up into the sky, and seeming almost immediately above us. Crossing the river on the ice, and leaving it immediately, we commenced the ascent of the mountain along the valley of a tributary stream. The people were unusually silent, for every man knew that our enterprise was hazardous; and the issue doubtful.

The snow deepened rapidly, and it soon became necessary to break a road. For this service, a party of ten was formed, mounted on the strongest horses, each man in succession opening the road on foot, or on horseback, until himself and his horse became fatigued, when he stepped aside, and, the remaining number passing ahead, he took his station in the rear. Leaving this stream, and pursuing a very direct course, we passed over an intervening ridge to the river we had left. On the way we passed two low huts entirely covered with snow, which might very easily have escaped observation. A family was living in each; and the only trail I saw in the neighborhood was from the door-hole to a nut-pine tree near, which supplied them with food and fuel. We found two similar huts on the creek where we next arrived; and, traveling a little higher up, encamped on its banks in about four feet depth of snow. Carson found near, an open hill- side, where the wind and the sun had melted the snow, leaving exposed sufficient bunch-grass for the animals to-night.

The nut-pines were now giving way to heavy timber, and there were some immense pines on the bottom, around the roots of which the sun had melted away the snow; and here we made our camp and built huge fires. To-day we had traveled 16 miles, and our elevation above the sea was 6,760 feet.

3d.--Turning our faces directly towards the main chain, we ascended an open hollow along a small tributary to the river, which, according to the Indians, issues from a mountain to the south. The snow was so deep in the hollow, that we were obliged to travel along the steep hill-sides, and over spurs, where the wind and sun had in places lessened the snow, and where the grass, which appeared to be in good quality along the sides of the mountains, was exposed. We opened our road in the same way as yesterday, but made only seven miles, and encamped by some springs at the foot of a high and steep hill, by which the hollow ascended to another basin in the mountain. The little stream below was entirely buried in snow. The springs were shaded by the boughs of a lofty cedar, which here made its first appearance; the usual height was 120 to 130 feet, and one that was measured near by was six feet in diameter.

There being no grass exposed here, the horses were sent back to that which we had seen a few miles below. We occupied the remainder of the day in beating down a road to the foot of the hill, a mile or two distant; the snow being beaten down when moist, in the warm part of the day, and then hard frozen at night, made a foundation that would bear the weight of the animals next morning. During the day several Indians joined us on snow- shoes. These were made of a circular hoop, about a foot in diameter, the interior space being filled with an open network of bark.

4th.--I went ahead early with two or three men, each with a led horse to break the road. We were obliged to abandon the hollow entirely, and work along the mountain-side, which was very steep, and the snow covered with an icy crust. We cut a footing as we advanced, and trampled a road through for the animals; but occasionally one plunged outside the trail, and slided along the field to the bottom, a hundred yards below. Late in the day we reached another bench in the hollow, where, in summer, the stream passed over a small precipice. Here was a short distance of dividing ground between the two ridges, and beyond an open basin, some ten miles across, whose bottom presented a field of snow. At the further or western side rose the middle crest of the mountain, a dark-looking ridge of volcanic rock.

The summit line presented a range of naked peaks, apparently destitute of snow and vegetation; but below, the face of the whole country was covered with timber of extraordinary size.

Towards a pass which the guide indicated here, we attempted in the afternoon to force a road; but after a laborious plunging through two or three hundred yards, our best horses gave out, entirely refusing to make any further effort, and, for the time, we were brought to a stand. The guide informed us that we were entering the deep snow, and here began the difficulties of the mountain; and to him, and almost to all, our enterprise seemed hopeless. I returned a short distance back, to the break in the hollow, where I met Mr. Fitzpatrick.

The camp had been occupied all the day in endeavoring to ascend the hill, but only the best horses had succeeded; the animals, generally, not having sufficient strength to bring themselves up without the packs; and all the line of road between this and the springs was strewed with camp-stores and equipage, and horses floundering in snow. I therefore immediately encamped on the ground with my own mess, which was in advance, and directed Mr. Fitzpatrick to encamp at the springs, and send all the animals, in charge of Tabeau, with a strong guard, back to the place where they had been pastured the night before. Here was a small spot of level ground, protected on one side by the mountain, and on the other sheltered by a little ridge of rock. It was an open grove of pines, which assimilated in size to the grandeur of the mountain, being frequently six feet in diameter.

To-night we had no shelter, but we made a large fire around the trunk of one of the huge pines; and covering the snow with small boughs, on which we spread our blankets, soon made ourselves comfortable. The night was very bright and clear, though the thermometer was only at 10°. A strong wind, which sprang up at sundown, made it intensely cold; and this was one of the bitterest nights during the journey.

Two Indians joined our party here; and one of them, an old man, immediately began to harangue us, saying that ourselves and animals would perish in the snow; and that if we would go back, he would show us another and a better way across the mountain. He spoke in a very loud voice, and there was a singular repetition of phrases and arrangement of words, which rendered his speech striking and not unmusical.

We had now begun to understand some words, and, with the aid of signs, easily comprehended the old man's simple ideas. "Rock upon rock--rock upon rock--snow upon snow," said he; "even if you get over the snow, you will not be able to get down from the mountains." He made us the sign of precipices, and showed us how the feet of the horses would slip, and throw them off from the narrow trails that led along their sides. Our Chinook, who comprehended even more readily than ourselves, and believed our situation hopeless, covered his head with his blanket, and began to weep and lament. "I wanted to see the whites," said he; "I came away from my own people to see the whites, and I wouldn't care to die among them, but here"--and he looked around into the cold night and gloomy forest, and, drawing his blanket over his head, began again to lament.

Seated around the tree, the fire illuminating the rocks and the tall bolls of the pines round about, and the old Indian haranguing, we presented a group of very serious faces.

5th.--The night had been too cold to sleep, and we were up very early. Our guide was standing by the fire with all his finery on; and seeing him shiver in the cold, I threw on his shoulders one of my blankets. We missed him a few minutes afterwards, and never saw him again. He had deserted. His bad faith and treachery were in perfect keeping with the estimate of Indian character, which a long intercourse with this people had gradually forced upon my mind.

While a portion of the camp were occupied in bringing up the baggage to this point, the remainder were busied in making sledges and snow-shoes. I had determined to explore the mountain ahead, and the sledges were to be used in transporting the baggage.

The mountains here consisted wholly of a white micaceous granite. The day was perfectly clear, and, while the sun was in the sky, warm and pleasant.

By observation our latitude was 38° 42' 26"; and elevation by the boiling point, 7,400 feet.

6th.--Accompanied by Mr. Fitzpatrick, I set out to-day with a reconnoitring party on snow-shoes. We marched all in single file, trampling the snow as heavily as we could. Crossing the open basin, in a march of about ten miles we reached the top of one of the peaks, to the left of the pass indicated by our guide. Far below us, dimmed by the distance, was a large snowless valley, bounded on the western side, at the distance of about a hundred miles, by a low range of mountains, which Carson recognised with delight as the mountains bordering the coast. "There," said he, "is the little mountain--it is fifteen years since I saw it; but I am just as sure as if I had seen it yesterday." Between us, then, and this low coast range was the valley of the Sacramento; and no one who had not accompanied us through the incidents of our life for the last few months could realize the delight with which at last we looked down upon it. At the distance of apparently 30 miles beyond us were distinguished spots of prairie; and a dark line which could be traced with the glass, was imagined to be the course of the river; but we were evidently at a great height above the valley, and between us and the plains extended miles of snowy fields and broken ridges of pine-covered mountains.

It was late in the day when we turned towards the camp; and it grew rapidly cold as it drew towards night. One of the men became fatigued, and his feet began to freeze, and building a fire in the trunk of a dry old cedar, Mr. Fitzpatrick remained with him until his clothes could be dried, and he was in a condition to come on. After a day's march of 20 miles, we straggled into the camp one after another, at nightfall; the greater number excessively fatigued, only two of the party having ever traveled on snow-shoes before.

All our energies are now directed to getting our animals across the snow; and it was supposed that after all the baggage had been drawn with the sleighs over the trail we had made, it would be sufficiently hard to bear our animals. At several places between this point and the ridge, we had discovered some grassy spots, where the wind and sun had dispersed the snow from the sides of the hills, and these were to form resting-places to support the animals for a night in their passage across. On our way across we had set on fire several broken stumps, and dried trees, to melt holes in the snow for the camps. Its general depth was five feet; but we passed over places where it was 20 feet deep, as shown by the trees. With one party drawing sleighs loaded with baggage, I advanced to-day about four miles along the trail, and encamped at the first grassy spot, where we expected to bring our horses. Mr. Fitzpatrick, with another party, remained behind, to form an intermediate station between us and the animals.

8th.--The night has been extremely cold; but perfectly still, and beautifully clear. Before the sun appeared this morning, the thermometer was 3° below zero; 1° higher, when his rays struck the lofty peaks; and 0° when they reached our camp.

Scenery and weather, combined, must render these mountains beautiful in summer; the purity and deep-blue color of the sky are singularly beautiful; the days are sunny and bright, and even warm in the noon hours; and if we could be free from the many anxieties that oppress us, even now we would be delighted here; but our provisions are getting fearfully scant. Sleighs arrived with baggage about ten o'clock; and leaving a portion of it here, we continued on for a mile and a half, and encamped at the foot of a long hill on this side of the open bottom.

Bernier and Godey, who yesterday morning had been sent to ascend a higher peak, got in, hungry and fatigued. They confirmed what we had already seen. Two other sleighs arrived in the afternoon; and the men being fatigued, I gave them all tea and sugar. Snow clouds began to rise in the S.S.W.; and, apprehensive of a storm, which would destroy our road, I sent the people back to Mr. Fitzpatrick, with directions to send for the animals in the morning. With me remained Mr. Preuss, Mr. Talbot, and Carson, with Jacob.

Elevation of the camp, by the boiling point, is 7,920 feet.

9th.--During the night the weather changed, the wind rising to a gale, and commencing to snow before daylight; before morning the trail was covered. We remained quiet in camp all day, in the course of which the weather improved. Four sleighs arrived towards evening, with the bedding of the men. We suffer much from the want of salt; and all the men are becoming weak from insufficient food.

10th.--Taplin was sent back with a few men to assist Mr. Fitzpatrick; and continuing on with three sleighs carrying a part of the baggage, we had the satisfaction to encamp within two and a half miles of the head of the hollow, and at the foot of the last mountain ridge. Here two large trees had been set on fire, and in the holes, where the snow had been melted away, we found a comfortable camp.

The wind kept the air filled with snow during the day; the sky was very dark in the southwest, though elsewhere very clear. The forest here has a noble appearance; and tall cedar is abundant; its greatest height being 130 feet, and circumference 20, three or four feet above the ground; and here I see for the first time the white pine, of which there are some magnificent trees. Hemlock spruce is among the timber, occasionally as large as eight feet in diameter, four feet above the ground; but, in ascending, it tapers rapidly to less than one foot at the height of eighty feet. I have not seen any higher than 130 feet, and the slight upper part is frequently broken off by the wind. The white spruce is frequent; and the red pine (pinus colorado of the Mexicans) which constitutes the beautiful forest along the banks of the Sierra Nevada to the northward, is here the principal tree, not attaining a greater height than 140 feet, though with sometimes a diameter of 10. Most of these trees appeared to differ slightly from those of the same kind on the other side of the continent.

The elevation of the camp by the boiling point, is 8,050 feet. We are now 1,000 feet above the level of the South Pass in the Rocky mountains; and still we are not done ascending. The top of a flat ridge near was bare of snow, and very well sprinkled with bunch-grass, sufficient to pasture the animals two or three days; and this was to be their main point of support. This ridge is composed of a compact trap, or basalt of a columnar structure; over the surface are scattered large boulders of porous trap. The hills are in many places entirely covered with small fragments of volcanic rock.

Putting on our snow-shoes, we spent the afternoon in exploring a road ahead. The glare of the snow, combined with great fatigue, had rendered many of the people nearly blind; but we were fortunate in having some black silk handkerchiefs, which, worn as veils, very much relieved the eye.

11th.--High wind continued, and our trail this morning was nearly invisible--here and there indicated by a little ridge of snow. Our situation became tiresome and dreary, requiring a strong exercise of patience and resolution.

In the evening I received a message from Mr. Fitzpatrick, acquainting me with the utter failure of his attempt to get our mules and horses over the snow--the half-hidden trail had proved entirely too slight to support them, and they had broken through, and were plunging about or lying half buried in snow. He was occupied in endeavoring to get them back to his camp; and in the mean time sent to me for further instructions. I wrote to him to send the animals immediately back to their old pastures; and, after having made mauls and shovels, turn in all the strength of his party to open and beat a road through the snow, strengthening it with branches and boughs of the pines.

12th.--We made mauls, and worked hard at our end of the road all day. The wind was high, but the sun bright, and the snow thawing. We worked down the face of the hill, to meet the people at the other end. Towards sundown it began to grow cold, and we shouldered our mauls and trudged back to camp.

13th.--We continued to labor on the road; and in the course of the day had the satisfaction to see the people working down the face of the opposite hill, about three miles distant. During the morning we had the pleasure of a visit from Mr. Fitzpatrick, with the information that all was going on well. A party of Indians had passed on snow-shoes, who said they were going to the western side of the mountain after fish. This was an indication that the salmon were coming up the streams; and we could hardly restrain our impatience as we thought of them, and worked with increased vigor.

The meat train did not arrive this evening, and I gave Godey leave to kill our little dog, (Tlamath,) which he prepared in Indian fashion; scorching off the hair, and washing the skin with soap and snow, and then cutting it up into pieces, which were laid on the snow. Shortly afterwards, the sleigh arrived with a supply of horse-meat; and we had to-night an extraordinary dinner--pea-soup, mule, and dog.

14th.--The dividing ridge of the Sierra is in sight from this encampment. Accompanied by Mr. Preuss, I ascended to-day the highest peak to the right; from which we had a beautiful view of a mountain lake at our feet, about fifteen miles in length, and so entirely surrounded by mountains that we could not discover an outlet. We had taken with us a glass; but though we enjoyed an extended view, the valley was half hidden in mist, as when we had seen it before. Snow could be distinguished on the higher parts of the coast mountains; eastward, as far as the eye could extend, it ranged over a terrible mass of broken snowy mountains, fading off blue in the distance. The rock composing the summit consists of a very coarse, dark, volcanic conglomerate; the lower parts appeared to be of a slaty structure. The highest trees were a few scattering cedars and aspens. From the immediate foot of the peak, we were two hours reaching the summit, and one hour and a quarter in descending. The day had been very bright, still, and clear, and spring seems to be advancing rapidly. While the sun is in the sky, the snow melts rapidly, and gushing springs cover the face of the mountain in all the exposed places; but their surface freezes instantly with the disappearance of the sun.

I obtained to-night some observations; and the result from these, and others made during our stay, gives for the latitude 38° 41' 57", longitude 120° 25' 57", and rate of the chronometer 25.82".

16th.--We had succeeded in getting our animals safely to the first grassy hill; and this morning I started with Jacob on a reconnoitring expedition beyond the mountain. We traveled along the crests of narrow ridges, extending down from the mountain in the direction of the valley, from which the snow was fast melting away. On the open spots was tolerably good grass; and I judged we should succeed in getting the camp down by way of these. Towards sundown we discovered some icy spots in a deep hollow; and, descending the mountain, we encamped on the head-water of a little creek, where at last the water found its way to the Pacific.

The night was clear and very long. We heard the cries of some wild animals, which had been attracted by our fire, and a flock of geese passed over during the night. Even these strange sounds had something pleasant to our senses in this region of silence and desolation.

We started again early in the morning. The creek acquired a regular breadth of about 20 feet, and we soon began to hear the rushing of the water below the icy surface, over which we traveled to avoid the snow; a few miles below we broke through, where the water was several feet deep, and halted to make a fire and dry our clothes. We continued a few miles farther, walking being very laborious without snow-shoes.

I was now perfectly satisfied that we had struck the stream on which Mr. Sutler lived; and, turning about, made a hard push, and reached the camp at dark. Here we had the pleasure to find all the remaining animals, 57 in number, safely arrived at the grassy hill near the camp; and here, also, we were agreeably surprised with the sight of an abundance of salt. Some of the horse-guard had gone to a neighboring hut for pine nuts, and discovered unexpectedly a large cake of very white fine-grained salt, which the Indians told them they had brought from the other side of the mountain; they used it to eat with their pine nuts, and readily sold it for goods.

On the 19th, the people were occupied in making a road and bringing up the baggage; and, on the afternoon of the next day, February 20, 1844, we encamped, with the animals and all the materiel of the camp, on the summit of the PASS in the dividing ridge, 1,000 miles by our traveled road from the Dalles to the Columbia.

The people, who had not yet been to this point, climbed the neighboring peak to enjoy a look at the valley.

The temperature of boiling water gave for the elevation of the encampment, 9,338 feet above the sea.

This was 2,000 feet higher than the South Pass in the Rocky mountains, and several peaks in view rose several thousand feet still higher. Thus, at the extremity of the continent, and near the coast, the phenomenon was seen of a range of mountains still higher than the great Rocky mountains themselves. This extraordinary fact accounts for the Great Basin, and shows that there must be a system of small lakes and rivers here scattered over a flat country, and which the extended and lofty range of the Sierra Nevada prevents from escaping to the Pacific ocean. Latitude 38° 44'; longitude 120° 28'.

Thus the Pass in the Sierra Nevada, which so well deserves its name of Snowy mountain, is eleven degrees west and about four degrees south of the South Pass.

21st.--We now considered ourselves victorious over the mountain; having only the descent before us, and the valley under our eyes, we felt strong hope that we should force our way down. But this was a case in which the descent was not facile. Still deep fields of snow lay between them, and there was a large intervening space of rough-looking mountains, through which we had yet to wind our way. Carson roused me this morning with an early fire, and we were all up long before day, in order to pass the snow-fields before the sun should render the crust soft. We enjoyed this morning a scene at sunrise, which even here was unusually glorious and beautiful. Immediately above the eastern mountains was repeated a cloud-formed mass of purple ranges, bordered with bright yellow gold; the peaks shot up into a narrow line of crimson cloud, above which the air was filled with a greenish orange; and over all was the singular beauty of the blue sky. Passing along a ridge which commanded the lake on our right, of which we began to discover an outlet through a chasm on the west, we passed over alternating open ground and hard-crusted snow-fields which supported the animals, and encamped on the ridge, after a journey of six miles. The grass was better than we had yet seen, and we were encamped in a clump of trees 20 or 30 feet high, resembling white pine. With the exception of these small clumps, the ridges were bare; and, where the snow found the support of the trees, the wind had blown it up into banks 10 or 15 feet high. It required much care to hunt out a practicable way, as the most open places frequently led to impassable banks.

We had hard and doubtful labor yet before us, as the snow appeared to be heavier where the timber began further down, with few open spots. Ascending a height, we traced out the best line we could discover for the next day's march, and had at least the consolation to see that the mountain descended rapidly. The day had been one of April--gusty, with a few occasional flakes of snow--which, in the afternoon, enveloped the upper mountain in clouds. We watched them anxiously, as now we dreaded a snow-storm. Shortly afterwards we heard the roll of thunder, and, looking towards the valley, found it enveloped in a thunder-storm. For us, as connected with the idea of summer, it had a singular charm, and we watched its progress with excited feelings until nearly sunset, when the sky cleared off brightly, and we saw a shining line of water directing its course towards another, a broader and larger sheet. We knew that these could be no other than the Sacramento and the Bay of San Francisco; but, after our long wandering in rugged mountains, where so frequently we had met with disappointments, and where the crossing of every ridge displayed some unknown lake or river, we were yet almost afraid to believe that we were at last to escape into the genial country of which we had heard so many glowing descriptions, and dreaded to find some vast interior lake, whose bitter waters would bring us disappointment. On the southern shore of what appeared to be the bay could be traced the gleaming line where entered another large stream; and again the Buenaventura rose up in our minds.

Carson had entered the valley along the southern side of the bay, and remembered perfectly to have crossed the mouth of a very large stream, which they had been obliged to raft; but the country then was so entirely covered with water from snow and rain, that he had been able to form no correct impressions of water-courses.

We had the satisfaction to know that at least there were people below. Fires were lit up in the valley just at night, appearing to be in answer to ours; and these signs of life renewed, in some measure, the gayety of the camp. They appeared so near, that we judged them to be among the timber of some of the neighboring ridges; but, having them constantly in view day after day, and night after night, we afterwards found them to be fires that had been kindled by the Indians among the tulares, on the shore of the bay, 80 miles distant.

Among the very few plants that appeared here, was the common blue flax. To-night a mule was killed for food.

22d.--Our breakfast was over long before day. We took advantage of the coolness of the early morning to get over the snow, which to-day occurred in very deep banks among the timber; but we searched out the coldest places, and the animals passed successfully with their loads over the hard crust. Now and then the delay of making a road occasioned much labor and loss of time. In the after part of the day, we saw before us a handsome grassy ridge point; and, making a desperate push over a snow-field 10 to 15 feet deep, we happily succeeded in getting the camp across, and encamped on the ridge, after a march of three miles. We had again the prospect of a thunder-storm below, and to-night we killed another mule-- now our only resource from starvation.

We satisfied ourselves during the day that the lake had an outlet between two ranges on the right; and with this, the creek on which I had encamped probably effected a junction below. Between these, we were descending.

We continued to enjoy the same delightful weather; the sky of the same beautiful blue, and such a sunset and sunrise as on our Atlantic coast we could scarcely imagine. And here among the mountains, 9,000 feet above the sea, we have the deep-blue sky and sunny climate of Smyrna and Palermo, which a little map before me shows are in the same latitude.

The elevation above the sea, by the boiling point, is 8,565 feet.

23d.--This was our most difficult day; we were forced off the ridges by the quantity of snow among the timber, and obliged to take to the mountain sides, where occasionally rocks and a southern exposure afforded us a chance to scramble along. But these were steep, and slippery with snow and ice; and the tough evergreens of the mountain impeded our way, tore our skins, and exhausted our patience. Some of us had the misfortune to wear moccasins with parflèche soles, so slippery that we could not keep our feet, and generally crawled across the snow-beds. Axes and mauls were necessary to-day, to make a road through the snow. Going ahead with Carson to reconnoitre the road, we reached in the afternoon the river which made the outlet of the lake. Carson sprang over, clear across a place where the stream was compressed among rocks, but the parflèche sole of my moccasin glanced from the icy rock, and precipitated me into the river. It was some few seconds before I could recover myself in the current, and Carson, thinking me hurt, jumped in after me, and we both had an icy bath. We tried to search awhile for my gun, which had been lost in the fall, but the cold drove us out; and making a large fire on the bank, after we had partially dried ourselves we went back to meet the camp. We afterwards found that the gun had been slung under the ice which lined the banks of the creek.

Using our old plan of breaking roads with alternate horses, we reached the creek in the evening, and encamped on a dry open place in the ravine.

Another branch, which we had followed, here comes in on the left; and from this point the mountain wall, on which we had traveled to-day, faces to the south along the right bank of the river, where the sun appears to have melted the snow; but the opposite ridge is entirely covered. Here, among the pines, the hill-side produces but little grass--barely sufficient to keep life in the animals. We had the pleasure to be rained upon this afternoon; and grass was now our greatest solicitude. Many of the men looked badly; and some this evening were giving out.

24th.--We rose at three in the morning for an astronomical observation, and obtained for the place a lat. of 38° 46' 58"; long. 120° 34' 20". The sky was clear and pure, with a sharp wind from the northeast, and the thermometer 2° below the freezing point.

We continued down the south face of the mountain; our road leading over dry ground, we were able to avoid the snow almost entirely. In the course of the morning, we struck a footpath, which we were generally able to keep; and the ground was soft to our animals' feet, being sandy, or covered with mould. Green grass began to make its appearance, and occasionally we passed a hill scatteringly covered with it. The character of the forest continued the same; and, among the trees, the pine with sharp leaves and very large cones was abundant, some of them being noble trees. We measured one that had 10 feet diameter, though the height was not more than 130 feet. All along, the river was a roaring torrent, its fall very great; and, descending with a rapidity to which we had long been strangers, to our great pleasure oak-trees appeared on the ridge, and soon became very frequent; on these I remarked great quantities of mistletoe. Rushes began to make their appearance; and at a small creek where they were abundant, one of the messes was left with the weakest horses, while we continued on.

The opposite mountain-side was very steep and continuous--unbroken by ravines, and covered with pines and snow; while on the side we were traveling, innumerable rivulets poured down from the ridge. Continuing on, we halted a moment at one of these rivulets, to admire some beautiful evergreen-trees, resembling live-oak, which shaded the little stream. They were forty to fifty feet high, and two in diameter, with a uniform tufted top; and the summer green of their beautiful foliage, with the singing birds, and the sweet summer wind which was whirling about the dry oak leaves, nearly intoxicated us with delight; and we hurried on, filled with excitement, to escape entirely from the horrid region of inhospitable snow, to the perpetual spring of the Sacramento.

When we had traveled about ten miles, the valley opened a little to an oak and pine bottom, through which ran rivulets closely bordered with rushes, on which our half-starved horses fell with avidity; and here we made our encampment. Here the roaring torrent has already become a river, and we had descended to an elevation of 3,864 feet.

Along our road to-day the rock was a white granite, which appears to constitute the upper part of the mountains on both the eastern and western slopes; while between, the central is a volcanic rock.

Another horse was killed to-night, for food.

25th.--Believing that the difficulties of the road were passed, and leaving Mr. Fitzpatrick to follow slowly, as the condition of the animals required, I started ahead this morning with a party of eight, consisting of myself, Mr. Preuss and Mr. Talbot, Carson, Derosier, Towns, Proue, and Jacob. We took with us some of the best animals, and my intention was to proceed as rapidly as possible to the house of Mr. Sutter, and return to meet the party with a supply of provisions and fresh animals.

Continuing down the river, which pursued a very direct westerly course through a narrow valley, with only a very slight and narrow bottom-land, we made twelve miles, and encamped at some old Indian huts, apparently a fishing-place on the river. The bottom was covered with trees of deciduous foliage, and overgrown with vines and rushes. On a bench of the hill near by, was a hill of fresh green grass, six inches long in some of the tufts which I had the curiosity to measure. The animals were driven here; and I spent part of the afternoon sitting on a large rock among them, enjoying the pauseless rapidity with which they luxuriated on the unaccustomed food.

The forest was imposing to-day in the magnificence of the trees; some of the pines, bearing large cones, were 10 feet in diameter. Cedars also abounded, and we measured one 28½ feet in circumference, four feet from the ground. This noble tree seemed here to be in its proper soil and climate. We found it on both sides of the Sierra, but most abundant on the west.

26th.--We continued to follow the stream, the mountains on either hand increasing in height as we descended, and shutting up the river narrowly in precipices, along which we had great difficulty to get our horses.

It rained heavily during the afternoon, and we were forced off the river to the heights above; whence we descended, at night-fall, the point of a spur between the river and a fork of nearly equal size, coming in from the right. Here we saw, on the lower hills, the first flowers in bloom, which occurred suddenly, and in considerable quantity--one of them a species of gilia.

The current in both streams (rather torrents than rivers) was broken by large boulders. It was late, and the animals fatigued; and not succeeding to find a ford immediately, we encamped, although the hill-side afforded but a few stray bunches of grass, and the horses, standing about in the rain, looked very miserable.

27th.--We succeeded in fording the stream, and made a trail by which we crossed the point of the opposite hill, which, on the southern exposure, was prettily covered with green grass, and we halted a mile from our last encampment. The river was only about 60 feet wide, but rapid, and occasionally deep, foaming among boulders, and the water beautifully clear. We encamped on the hill-slope, as there was no bottom level, and the opposite ridge is continuous, affording no streams.

We had with us a large kettle; and a mule being killed here, his head was boiled in it for several hours, and made a passable soup for famished people.

Below, precipices on the river forced us to the heights, which we ascended by a steep spur 2,000 feet high. My favorite horse, Proveau, had become very weak, and was scarcely able to bring himself to the top. Traveling here was good, except in crossing the ravines, which were narrow, steep, and frequent. We caught a glimpse of a deer, the first animal we had seen; but did not succeed in approaching him. Proveau could not keep up, and I left Jacob to bring him on, being obliged to press forward with the party, as there was no grass in the forest. We grew very anxious as the day advanced and no grass appeared, for the lives of our animals depended on finding it to-night. They were in just such a condition that grass and repose for the night enabled them to get on the next day. Every hour we had been expecting to see open out before us the valley, which, from the mountain above, seemed almost at our feet. A new and singular shrub, which had made its appearance since crossing the mountain, was very frequent to- day. It branched out near the ground, forming a clump eight to ten feet high, with pale-green leaves, of an oval form; and the body and branches had a naked appearance, as if stripped of the bark, which is very smooth and thin, of a chocolate color, contrasting well with the pale green of the leaves. The day was nearly gone; we had made a hard day's march, and found no grass. Towns became light-headed, wandering off into the woods without knowing where he was going, and Jacob brought him back.

Near night-fall we descended into the steep ravine of a handsome creek 30 feet wide, and I was engaged in getting the horses up the opposite hill, when I heard a shout from Carson, who had gone ahead a few hundred yards-- "Life yet," said he, as he came up, "life yet; I have found a hill-side sprinkled with grass enough for the night." We drove along our horses, and encamped at the place about dark, and there was just room enough to make a place for shelter on the edge of the stream. Three horses were lost to- day--Proveau; a fine young horse from the Columbia, belonging to Charles Towns; and another Indian horse, which carried our cooking utensils. The two former gave out, and the latter strayed off into the woods as we reached the camp.

29th.--We lay shut up in the narrow ravine, and gave the animals a necessary day; and men were sent back after the others. Derosier volunteered to bring up Proveau, to whom he knew I was greatly attached, as he had been my favorite horse on both expeditions. Carson and I climbed one of the nearest mountains; the forest land still extended ahead, and the valley appeared as far as ever. The pack-horse was found near the camp; but Derosier did not get in.

MARCH.

1st.--Derosier did not get in during the night, and leaving him to follow, as no grass remained here, we continued on over the uplands, crossing many small streams, and camped again on the river, having made six miles. Here we found the hillside covered (although lightly) with fresh green grass; and from this time forward we found it always improving and abundant.

We made a pleasant camp on the river hill, where were some beautiful specimens of the chocolate-colored shrub, which were a foot in diameter near the ground, and fifteen to twenty feet high. The opposite ridge runs continuously along, unbroken by streams. We are rapidly descending into the spring, and we are leaving our snowy region far behind; every thing is getting green; butterflies are swarming; numerous bugs are creeping out, wakened from their winter's sleep; and the forest flowers are coming into bloom. Among those which appeared most numerously to-day was dodecatheon dentatum.

We began to be uneasy at Derosier's absence, fearing he might have been bewildered in the woods. Charles Towns, who had not yet recovered his mind, went to swim in the river, as if it were summer, and the stream placid, when it was a cold mountain torrent foaming among the rocks. We were happy to see Derosier appear in the evening. He came in, and, sitting down by the fire, began to tell us where he had been. He imagined he had been gone several days, and thought we were still at the camp where he had left us; and we were pained to see that his mind was deranged. It appeared that he had been lost in the mountain, and hunger and fatigue, joined to weakness of body and fear of perishing in the mountains, had crazed him. The times were severe when stout men lost their minds from extremity of suffering--when horses died--and when mules and horses, ready to die of starvation, were killed for food. Yet there was no murmuring or hesitation.

A short distance below our encampment the river mountains terminated in precipices, and, after a fatiguing march of only a few miles, we encamped on a bench where there were springs, and an abundance of the freshest grass. In the mean time, Mr. Preuss continued on down the river, and, unaware that we had encamped so early in the day, was lost. When night arrived, and he did not come in, we began to understand what had happened to him; but it was too late to make any search.

3d.--We followed Mr. Preuss' trail for a considerable distance along the river, until we reached a place where he had descended to the stream below and encamped. Here we shouted and fired guns, but received no answer; and we concluded that he had pushed on down the stream. I determined to keep out from the river, along which it was nearly impracticable to travel with animals, until it should form a valley. At every step the country improved in beauty; the pines were rapidly disappearing, and oaks became the principal trees of the forest. Among these, the prevailing tree was the evergreen oak, (which, by way of distinction, we call the live- oak;) and with these occurred frequently a new species of oak bearing a long slender acorn, from an inch to an inch and a half in length, which we now began to see formed the principal vegetable food of the inhabitants of this region. In a short distance we crossed a little rivulet, where were two old huts, and near by were heaps of acorn hulls. The ground round about was very rich, covered with an exuberant sward of grass; and we sat down for a while in the shade of the oaks, to let the animals feed. We repeated our shouts for Mr. Preuss; and this time were gratified with an answer. The voice grew rapidly nearer, ascending from the river; but when we expected to see him emerge, it ceased entirely. We had called up some straggling Indian--the first we had met, although for two days back we had seen tracks--who, mistaking us for his fellows, had been only undeceived on getting close up. It would have been pleasant to witness his astonishment; he would not have been more frightened had some of the old mountain spirits they are so much afraid of suddenly appeared in his path. Ignorant of the character of these people, we had now an additional cause of uneasiness in regard to Mr. Preuss; he had no arms with him, and we began to think his chance doubtful. We followed on a trail, still keeping out from the river, and descended to a very large creek, dashing with great velocity over a pre-eminently rocky bed, and among large boulders. The bed had sudden breaks, formed by deep holes and ledges of rock running across. Even here, it deserves the name of Rock creek, which we gave to it. We succeeded in fording it, and toiled about three thousand feet up the opposite hill. The mountains now were getting sensibly lower; but still there is no valley on the river, which presents steep and rocky banks; but here, several miles from the river, the country is smooth and grassy; the forest has no undergrowth; and in the open valleys of rivulets, or around spring-heads, the low groves of live-oak give the appearance of orchards in an old cultivated country. Occasionally we met deer, but had not the necessary time for hunting. At one of these orchard- grounds, we encamped about noon to make an effort for Mr. Preuss. One man took his way along a spur leading into the river, in hope to cross his trail; and another took our own back. Both were volunteers; and to the successful man was promised a pair of pistols--not as a reward, but as a token of gratitude for a service which would free us all from much anxiety.

We had among our few animals a horse which was so much reduced, that, with traveling, even the good grass could nor save him; and, having nothing to eat, he was killed this afternoon. He was a good animal, and had made the journey round from Fort Hall.

Dodecatheon dentatum continued the characteristic plant in flower; and the naked-looking shrub already mentioned continued characteristic, beginning to put forth a small white blossom. At evening the men returned, having seen or heard nothing of Mr. Preuss; and I determined to make a hard push down the river the next morning and get ahead of him.

4th.--We continued rapidly along on a broad plainly-beaten trail, the mere traveling and breathing the delightful air being a positive enjoyment. Our road led along a ridge inclining to the river, and the air and the open grounds were fragrant with flowering shrubs; and in the course of the morning we issued on an open spur, by which we descended directly to the stream. Here the river issues suddenly from the mountains, which hitherto had hemmed it closely in; these now become softer, and change sensibly their character; and at this point commences the most beautiful valley in which we had ever traveled. We hurried to the river, on which we noticed a small sand beach, to which Mr. Preuss would naturally have gone. We found no trace of him, but, instead, were recent tracks of bare-footed Indians, and little piles of muscle-shells, and old fires where they had roasted the fish. We traveled on over the river grounds, which were undulating, and covered with grass to the river brink. We halted to noon a few miles beyond, always under the shade of the evergreen oaks, which formed open groves on the bottoms.

Continuing our road in the afternoon, we ascended to the uplands, where the river passes round a point of great beauty, and goes through very remarkable dalles, in character resembling those of the Columbia. Beyond, we again descended to the bottoms, where we found an Indian village, consisting of two or three huts; we had come upon them suddenly, and the people had evidently just run off. The huts were low and slight, made like beehives in a picture, five or six feet high, and near each was a crate, formed of interlaced branches and grass, in size and shape like a very large hogshead. Each of these contained from six to nine bushels. These were filled with the long acorns already mentioned, and in the huts were several neatly-made baskets, containing quantities of the acorns roasted. They were sweet and agreeably flavored, and we supplied ourselves with about half a bushel, leaving one of our shirts, a handkerchief, and some smaller articles, in exchange. The river again entered for a space among the hills, and we followed a trail leading across a bend through a handsome hollow behind. Here, while engaged in trying to circumvent a deer, we discovered some Indians on a hill several hundred yards ahead, and gave them a shout, to which they responded by loud and rapid talking and vehement gesticulation, but made no stop, hurrying up the mountain as fast as their legs could carry them. We passed on, and again encamped in a grassy grove.

The absence of Mr. Preuss gave me great concern; and, for a large reward, Derosier volunteered to go back on the trail. I directed him to search along the river, traveling upward for the space of a day and a half, at which time I expected he would meet Mr. Fitzpatrick, whom I requested to aid in the search; at all events, he was to go no farther, but return to this camp, where a cache of provisions was made for him.

Continuing the next day down the river, we discovered three squaws in a little bottom, and surrounded them before they could make their escape. They had large conical baskets, which they were engaged in filling with a small leafy plant (erodium cicutarium) just now beginning to bloom, and covering the ground like a sward of grass. These did not make any lamentations, but appeared very much impressed with our appearance, speaking to us only in a whisper, and offering us smaller baskets of the plant, which they signified to us was good to eat, making signs also that it was to be cooked by the fire. We drew out a little cold horse-meat, and the squaws made signs to us that the men had gone out after deer, and that we could have some by waiting till they came in. We observed that the horses ate with great avidity the herb which they had been gathering; and here also, for the first time, we saw Indians eat the common grass--one of the squaws pulling several tufts, and eating it with apparent relish. Seeing our surprise, she pointed to the horses; but we could not well understand what she meant, except, perhaps, that what was good for the one was good for the other.

We encamped in the evening on the shore of the river, at a place where the associated beauties of scenery made so strong an impression on us that we gave it the name of the Beautiful Camp. The undulating river shore was shaded with the live-oaks, which formed a continuous grove over the country, and the same grassy sward extended to the edge of the water, and we made our fires near some large granite masses which were lying among the trees. We had seen several of the acorn caches during the day, and here there were two which were very large, containing each, probably, ten bushels. Towards evening we heard a weak shout among the hills behind, and had the pleasure to see Mr. Preuss descending towards the camp. Like ourselves, he had traveled to-day 25 miles, but had seen nothing of Derosier. Knowing, on the day he was lost, that I was determined to keep the river as much as possible, he had not thought it necessary to follow the trail very closely, but walked on, right and left, certain to find it somewhere along the river, searching places to obtain good views of the country. Towards sunset he climbed down towards the river to look for the camp; but, finding no trail, concluded that we were behind, and walked back till night came on, when, being very much fatigued, he collected drift-wood and made a large fire among the rocks. The next day it became more serious and he encamped again alone, thinking that we must have taken some other course. To go back would have been madness in his weak and starved condition, and onward towards the valley was his only hope, always in expectation of reaching it soon. His principal means of subsistence were a few roots, which the hunters call sweet onions, having very little taste, but a good deal of nutriment, growing generally in rocky ground, and requiring a good deal of labor to get, as he had only a pocket-knife. Searching for these, he found a nest of big ants, which he let run on his hand, and stripped them off in his mouth; these had an agreeable acid taste. One of his greatest privations was the want of tobacco; and a pleasant smoke at evening would have been a relief which only a voyageur could appreciate. He tried the dried leaves of the live-oak, knowing that those of other oaks were sometimes used as a substitute; but these were too thick, and would not do. On the 4th he made seven or eight miles, walking slowly along the river, avoiding as much as possible to climb the hills. In little pools he caught some of the smallest kind of frogs, which he swallowed, not so much in the gratification of hunger, as in the hope of obtaining some strength. Scattered along the river were old fire- places, where the Indians had roasted muscles and acorns; but though he searched diligently, he did not there succeed in finding either. He had collected firewood for the night, when he heard, at some distance from the river, the barking of what he thought were two dogs, and walked in that direction as quickly as he was able, hoping to find there some Indian hut, but met only two wolves; and, in his disappointment, the gloom of the forest was doubled.

Traveling the next day feebly down the river, he found five or six Indians at the huts of which we have spoken: some were painting themselves black, and others roasting acorns. Being only one man, they did not run off, but received him kindly, and gave him a welcome supply of roasted acorns. He gave them his pocket-knife in return, and stretched out his hand to one of the Indians, who did not appear to comprehend the motion, but jumped back, as if he thought he was about to lay hold of him. They seemed afraid of him, not certain as to what he was.

Traveling on, he came to the place where we had found the squaws. Here he found our fire still burning, and the tracks of the horses. The sight gave him sudden hope and courage; and, following as fast as he could, joined us at evening.

6th.--We continued on our road through the same surpassingly beautiful country, entirely unequalled for the pasturage of stock by any thing we had ever seen. Our horses had now become so strong that they were able to carry us, and we traveled rapidly--over four miles an hour; four of us riding every alternate hour. Every few hundred yards we came upon a little band of deer; but we were too eager to reach the settlement, which we momentarily expected to discover, to halt for any other than a passing shot. In a few hours we reached a large fork, the northern branch of the river, and equal in size to that which we had descended. Together they formed a beautiful stream, 60 to 100 yards wide; which at first, ignorant of the nature of the country through which that river ran, we took to be the Sacramento.

We continued down the right bank of the river, traveling for a while over a wooded upland, where we had the delight to discover tracks of cattle. To the southwest was visible a black column of smoke, which we had frequently noticed in descending, arising from the fires we had seen from the top of the Sierra. From the upland we descended into broad groves on the river, consisting of the evergreen, and a new species of a white-oak, with a large tufted top, and three to six feet in diameter. Among these was no brushwood; and the grassy surface gave to it the appearance of parks in an old-settled country. Following the tracks of the horses and cattle, in search of people, we discovered a small village of Indians. Some of these had on shirts of civilized manufacture, but were otherwise naked, and we could understand nothing from them: they appeared entirely astonished at seeing us.

We made an acorn meal at noon, and hurried on; the valley being gay with flowers, and some of the banks being absolutely golden with the Californian poppy, (eschescholtzia crocea.) Here the grass was smooth and green, and the groves very open; the large oaks throwing a broad shade among sunny spots. Shortly afterwards we gave a shout at the appearance, on a little bluff, of a neatly-built adobe house, with glass windows. We rode up, but, to our disappointment, found only Indians. There was no appearance of cultivation, and we could see no cattle; and we supposed the place had been abandoned. We now pressed on more eagerly than ever: the river swept round a large bend to the right; the hills lowered down entirely; and, gradually entering a broad valley, we came unexpectedly into a large Indian village, where the people looked clean, and wore cotton shirts and various other articles of dress. They immediately crowded around us, and we had the inexpressible delight to find one who spoke a little indifferent Spanish, but who at first confounded us by saying there were no whites in the country; but just then a well-dressed Indian came up, and made his salutations in very well- spoken Spanish. In answer to our inquiries, he informed us that we were upon the Rio de los Americanos, (the river of the Americans,) and that it joined the Sacramento river about ten miles below. Never did a name sound more sweetly! We felt ourselves among our countrymen; for the name of American, in these distant parts, is applied to the citizens of the United States. To our eager inquiries he answered, "I am a vaquero (cowherd) in the service of Capt. Sutter, and the people of this rancheria work for him." Our evident satisfaction made him communicative; and he went on to say that Capt. Sutter was a very rich man, and always glad to see his country people. We asked for his house.

He answered, that it was just over the hill before us; and offered, if we would wait a moment, to take his horse and conduct us to it. We readily accepted this civil offer. In a short distance we came in sight of the fort; and, passing on the way the house of a settler on the opposite side, (a Mr. Sinclair,) we forded the river; and in a few miles were met, a short distance from the fort, by Capt. Sutter himself. He gave us a most frank and cordial reception--conducted us immediately to his residence-- and under his hospitable roof we had a night of rest, enjoyment, and refreshment, which none but ourselves could appreciate. But the party left in the mountains, with Mr. Fitzpatrick, were to be attended to; and the next morning, supplied with fresh horses and provisions, I hurried off to meet them. On the second day we met, a few miles below the forks of the Rio de los Americanos; and a more forlorn and pitiable sight than they presented, cannot well be imagined. They were all on foot--each man, weak and emaciated, leading a horse or mule as weak and emaciated as themselves. They had experienced great difficulty in descending the mountains, made slippery by rains and melting snows, and many horses fell over precipices, and were killed; and with some were lost the packs they carried. Among these, was a mule with the plants which we had collected since leaving Fort Hall, along a line of 2,000 miles' travel. Out of 67 horses and mules, with which we commenced crossing the Sierra, only 33 reached the valley of the Sacramento, and they only in a condition to be led along. Mr. Fitzpatrick and his party, traveling more slowly, had been able to make some little exertion at hunting, and had killed a few deer. The scanty supply was a great relief to them; for several had been made sick by the strange and unwholesome food which the preservation of life compelled them to use. We stopped and encamped as soon as we met; and a repast of good beef, excellent bread, and delicious salmon, which I had brought along, was their first relief from the sufferings of the Sierra, and their first introduction to the luxuries of the Sacramento. It required all our philosophy and forbearance to prevent plenty from becoming as hurtful to us now, as scarcity had been before.

The next day, March 8th, we encamped at the junction of the two rivers, the Sacramento and Americanos; and thus found the whole party in the beautiful valley of the Sacramento. It was a convenient place for the camp; and, among other things, was within reach of the wood necessary to make the pack-saddles, which we should need on our long journey home, from which we were farther distant now than we were four months before, when from the Dalles of the Columbia we so cheerfully took up the homeward line of march.

Captain Sutter emigrated to this country from the western part of Missouri in 1838-39, and formed the first settlement in the valley, on a large grant of land which he obtained from the Mexican Government. He had, at first, some trouble with the Indians; but, by the occasional exercise of well-timed authority, he has succeeded in converting them into a peaceable and industrious people. The ditches around his extensive wheat-fields; the making of the sun-dried bricks, of which his fort is constructed; the ploughing, harrowing, and other agricultural operations, are entirely the work of these Indians, for which they receive a very moderate compensation--principally in shirts, blankets, and other articles of clothing. In the same manner, on application to the chief of a village, he readily obtains as many boys and girls as he has any use for. There were at this time a number of girls at the fort, in training for a future woolen factory; but they were now all busily engaged in constantly watering the gardens, which the unfavorable dryness of the season rendered necessary. The occasional dryness of some seasons, I understood to be the only complaint of the settlers in this fertile valley, as it sometimes renders the crops uncertain. Mr. Sutter was about making arrangements to irrigate his lands by means of the Rio de los Americanos. He had this year sown, and altogether by Indian labor, three hundred fanegas of wheat.

A few years since, the neighboring Russian establishment of Ross, being about to withdraw from the country, sold to him a large number of stock, with agricultural and other stores, with a number of pieces of artillery and other munitions of war; for these, a regular yearly payment is made in grain.

The fort is a quadrangular adobe structure, mounting twelve pieces of artillery, (two of them brass,) and capable of admitting a garrison of a thousand men; this, at present, consists of forty Indians in uniform-- one of whom was always found on duty at the gate. As might naturally be expected, the pieces are not in very good order. The whites in the employment of Capt. Sutter, American, French, and German, amount, perhaps, to thirty men. The inner wall is formed into buildings, comprising the common quarters, with blacksmith and other workshops; the dwelling-house, with a large distillery-house, and other buildings, occupying more the centre of the area.

It is built upon a pond-like stream, at times a running creek communicating with the Rio de los Americanos, which enters the Sacramento about two miles below. The latter is here a noble river, about three hundred yards broad, deep and tranquil, with several fathoms of water in the channel, and its banks continuously timbered. There were two vessels belonging to Capt. Sutter at anchor near the landing--one a large two- masted lighter, and the other a schooner, which was shortly to proceed on a voyage to Fort Vancouver for a cargo of goods.

Since his arrival, several other persons, principally Americans, have established themselves in the valley. Mr. Sinclair, from whom I experienced much kindness during my stay, is settled a few miles distant, on the Rio de los Americanos. Mr. Coudrois, a gentleman from Germany, has established himself on Feather river, and is associated with Capt. Sutter in agricultural pursuits. Among other improvements, they are about to introduce the cultivation of rape-seed, (brassica rapus,) which there is every reason to believe is admirably adapted to the climate and soil. The lowest average produce of wheat, as far as we can at present know, is thirty-five fanegas for one sown; but, as an instance of its fertility, it may be mentioned that Señor Valejo obtained, on a piece of ground where sheep had been pastured, 800 fanegas for eight sown. The produce being different in various places, a very correct idea cannot be formed.

An impetus was given to the active little population by our arrival, as we were in want of every thing. Mules, horses, and cattle, were to be collected; the horse-mill was at work day and night, to make sufficient flour; the blacksmith's shop was put in requisition for horse-shoes and bridle-bits; and pack-saddles, ropes, and bridles, and all the other little equipments of the camp, were again to be provided.

The delay thus occasioned was one of repose and enjoyment, which our situation required, and, anxious as we were to resume our homeward journey, was regretted by no one. In the mean time, I had the pleasure to meet with Mr. Chiles, who was residing at a farm on the other side of the river Sacramento, while engaged in the selection of a place for a settlement, for which he had received the necessary grant of land from the Mexican government.

It will be remembered that we had parted near the frontier of the states, and that he had subsequently descended the valley of Lewis's fork, with a party of ten or twelve men, with the intention of crossing the intermediate mountains to the waters of the Bay of San Francisco. In the execution of this design, and aided by subsequent information, he left the Columbia at the mouth of Malheur river, and, making his way to the head-waters of the Sacramento with a part of his company, traveled down that river to the settlements of Nueva Helvetia. The other party, to whom he had committed his wagons, and mill-irons, and saws, took a course further to the south, and the wagons and their contents were lost.

On the 22d we made a preparatory move, and encamped near the settlement of Mr. Sinclair, on the left bank of the Rio de los Americanos. I had discharged five of the party; Neal, the blacksmith, (an excellent workman, and an unmarried man, who had done his duty faithfully, and had been of very great service to me,) desired to remain, as strong inducements were offered here to mechanics.

Although at considerable inconvenience to myself, his good conduct induced me to comply with his request; and I obtained for him from Capt. Sutter, a present compensation of two dollars and a half per diem, with a promise that it should be increased to five, if he proved as good a workman as had been represented. He was more particularly an agricultural blacksmith. The other men were discharged with their own consent.

While we remained at this place, Derosier, one of our best men, whose steady good conduct had won my regard, wandered off from the camp, and never returned to it again, nor has he since been heard of.

24th.--We resumed our journey with an ample stock of provisions and a large cavalcade of animals, consisting of 130 horses and mules, and about 30 head of cattle, five of which were milch-cows. Mr. Sutter furnished us also with an Indian boy, who had been trained as a vaquero, and who would be serviceable in managing our cavalcade, great part of which were nearly as wild as buffalo, and who was, besides, very anxious to go along with us. Our direct course home was east, but the Sierra would force us south, above 500 miles of traveling, to a pass at the head of the San Joaquin river. This pass, reported to be good, was discovered by Mr. Joseph Walker, of whom I have already spoken, and whose name it might therefore appropriately bear. To reach it, our course lay along the valley of the San Joaquin--the river on our right, and the lofty wall of the impassable Sierra on the left. From that pass we were to move southeastwardly, having the Sierra then on the right, and reach the "Spanish trail," deviously traced from one watering-place to another, which constituted the route of the caravans from Puebla de los Angelos, near the coast of the Pacific, to Santa Fé of New Mexico. From the pass to this trail was 150 miles. Following that trail through a desert, relieved by some fertile plains indicated by the recurrence of the term vegas, until it turned to the right to cross the Colorado, our course would be northeast until we regained the latitude we had lost in arriving at Eutah lake, and thence to the Rocky mountains at the head of the Arkansas. This course of traveling, forced upon us by the structure of the country, would occupy a computed distance of 2,000 miles before we reached the head of the Arkansas--not a settlement to be seen upon it--and the names of places along it, all being Spanish or Indian, indicated that it had been but little trod by American feet. Though long, and not free from hardships, this route presented some points of attraction, in tracing the Sierra Nevada--turning the Great Basin, perhaps crossing its rim on the south--completely solving the problem of any river, except the Colorado, from the Rocky mountains on that part of our continent --and seeing the southern extremity of the Great Salt lake, of which the northern part had been examined the year before.

Taking leave of Mr. Sutter, who, with several gentlemen, accompanied us a few miles on our way, we traveled about 18 miles, and encamped on the Rio de los Cosumnes, a stream receiving its name from the Indians who live in its valley. Our road was through a level country, admirably suited to cultivation, and covered with groves of oak-trees, principally the evergreen-oak, and a large oak already mentioned, in form like those of the white-oak. The weather, which here, at this season, can easily be changed from the summer heat of the valley to the frosty mornings and bright days nearer the mountains, continued delightful for travelers, but unfavorable to the agriculturists, whose crops of wheat began to wear a yellow tinge from want of rain.

25th.--We traveled for 28 miles over the same delightful country as yesterday, and halted in a beautiful bottom at the ford of the Rio de los Mukelemnes, receiving its name from another Indian tribe living on the river. The bottoms on the stream are broad, rich, and extremely fertile, and the uplands are shaded with oak groves. A showy lupinus, of extraordinary beauty, growing four to five feet in height, and covered with spikes in bloom, adorned the banks of the river, and filled the air with a light and grateful perfume.

On the 26th we halted at the Arroyo de las Calaveras, (Skull creek,) a tributary to the San Joaquin--the previous two streams entering the bay between the San Joaquin and Sacramento rivers. This place is beautiful, with open groves of oak, and a grassy sward beneath, with many plants in bloom, some varieties of which seem to love the shade of the trees, and grow there in close small fields. Near the river, and replacing the grass, are great quantities of ammole, (soap plant,) the leaves of which are used in California for making, among other things, mats for saddle-cloths. A vine with a small white flower, (melothria?) called here la yerba buena, and which, from its abundance, gives name to an island and town in the bay, was to-day very frequent on our road--sometimes running on the ground or climbing the trees.

27th.--To-day we traveled steadily and rapidly up the valley; for, with our wild animals, any other gait was impossible, and making about five miles an hour. During the earlier part of the day, our ride had been over a very level prairie, or rather a succession of long stretches of prairie, separated by lines and groves of oak timber, growing along dry gullies, which are filled with water in seasons of rain; and, perhaps, also, by the melting snows. Over much of this extent, the vegetation was sparse; the surface showing plainly the action of water, which, in the season of flood, the Joaquin spreads over the valley. About one o'clock we came again among innumerable flowers; and a few miles further, fields of the beautiful blue-flowering lupine, which seems to love the neighborhood of water, indicated that we were approaching a stream. We here found this beautiful shrub in thickets, some of them being 12 feet in height. Occasionally three or four plants were clustered together, forming a grand bouquet, about 90 feet in circumference, and 10 feet high; the whole summit covered with spikes of flowers, the perfume of which is very sweet and grateful. A lover of natural beauty can imagine with what pleasure we rode among these flowering groves, which filled the air with a light and delicate fragrance. We continued our road for about a half a mile, interspersed through an open grove of live-oaks, which, in form, were the most symmetrical and beautiful we had yet seen in this country. The ends of their branches rested on the ground, forming somewhat more than a half sphere of very full and regular figure, with leaves apparently smaller than usual.

The Californian poppy, of a rich orange color, was numerous to-day. Elk and several bands of antelope made their appearance.

Our road was now one continued enjoyment; and it was pleasant riding among this assemblage of green pastures with varied flowers and scattered groves, and out of the warm green spring to look at the rocky and snowy peaks where lately we had suffered so much. Emerging from the timber, we came suddenly upon the Stanislaus river, where we hoped to find a ford, but the stream was flowing by, dark and deep, swollen by the mountain snows; its general breadth was about 50 yards.

We traveled about five miles up the river, and encamped without being able to find a ford. Here we made a large coral, in order to be able to catch a sufficient number of our wild animals to relieve those previously packed.

Under the shade of the oaks, along the river, I noticed erodium cicutarium in bloom, eight or ten inches high. This is the plant which we had seen the squaws gathering on the Rio de los Americanos. By the inhabitants of the valley it is highly esteemed for fattening cattle, which appear to be very fond of it. Here, where the soil begins to be sandy, it supplies to a considerable extent the want of grass.

Desirous, as far as possible, without delay, to include in our examination the San Joaquin river, I returned this morning down the Stanislaus for 17 miles, and again encamped without having found a fording-place. After following it for eight miles further the next morning, and finding ourselves in the vicinity of the San Joaquin, encamped in a handsome oak grove, and, several cattle being killed, we ferried over our baggage in their skins. Here our Indian boy, who probably had not much idea of where he was going, and began to be alarmed at the many streams which we were rapidly putting between him and the village, deserted.

Thirteen head of cattle took a sudden fright, while we were driving them across the river, and galloped off. I remained a day in the endeavor to recover them; but, finding they had taken the trail back to the fort, let them go without further effort. Here we had several days of warm and pleasant rain, which doubtless saved the crops below.

APRIL.

On the 1st of April, we made 10 miles across a prairie without timber, when we were stopped again by another large river, which is called the Rio de la Merced, (river of our Lady of Mercy.) Here the country had lost its character of extreme fertility, the soil having become more sandy and light; but, for several days past, its beauty had been increased by the additional animation of animal life; and now, it is crowded with bands of elk and wild horses; and along the rivers are frequent fresh tracks of grizzly bear, which are unusually numerous in this country.

Our route had been along the timber of the San Joaquin, generally about eight miles distant, over a high prairie.

In one of the bands of elk seen to-day, there were about 200; but the larger bands, both of these and wild horses, are generally found on the other side of the river, which, for that reason, I avoided crossing. I had been informed below, that the droves of wild horses were almost invariably found on the western bank of the river; and the danger of losing our animals among them, together with the wish of adding to our reconnoissance the numerous streams which run down from the Sierra, decided me to travel up the eastern bank.

2d.--The day was occupied in building a boat, and ferrying our baggage across the river; and we encamped on the bank. A large fishing eagle was slowly sailing along, looking after salmon; and there were some pretty birds in the timber, with partridges, ducks and geese innumerable in the neighborhood. We were struck with the tameness of the latter bird at Helvetia, scattered about in flocks near the wheat-fields, and eating grass on the prairie; a horseman would ride by within 30 yards, without disturbing them.

3d.--To-day we touched several times the San Joaquin river--here a fine- looking tranquil stream, with a slight current, and apparently deep. It resembled the Missouri in color, with occasional points of white sand; and its banks, where steep, were a kind of sandy clay; its average width appeared to be about eighty yards. In the bottoms are frequent ponds, where our approach disturbed multitudes of wild fowl, principally geese. Skirting along the timber, we frequently started elk; and large bands were seen during the day, with antelope and wild horses. The low country and the timber rendered it difficult to keep the main line of the river; and this evening we encamped on a tributary stream, about five miles from its mouth. On the prairie bordering the San Joaquin bottoms, there occurred during the day but little grass, and in its place was a sparse and dwarf growth of plants; the soil being sandy, with small bare places and hillocks, reminded me much of the Platte bottoms; but, on approaching the timber, we found a more luxuriant vegetation, and at our camp was an abundance of grass and pea-vines.

The foliage of the oak is getting darker; and every thing, except that the weather is a little cool, shows that spring is rapidly advancing; and to- day we had quite a summer rain.

4th.--Commenced to rain at daylight, but cleared off brightly at sunrise. We ferried the river without any difficulty, and continued up the San Joaquin. Elk were running in bands over the prairie and in the skirt of the timber. We reached the river at the mouth of a large slough, which we were unable to ford, and made a circuit of several miles around. Here the country appears very flat; oak-trees have entirely disappeared, and are replaced by a large willow, nearly equal to it in size. The river is about a hundred yards in breadth, branching into sloughs, and interspersed with islands. At this time it appears sufficiently deep for a small steamer, but its navigation would be broken by shallows at low water. Bearing in towards the river, we were again forced off by another slough; and passing around, steered towards a clump of trees on the river, and finding there good grass, encamped. The prairies along the left bank are alive with immense droves of wild horses; and they had been seen during the day at every opening through the woods which afforded us a view across the river. Latitude, by observation, 37° 08' 00"; longitude 120° 45' 22".

5th--During the earlier part of the day's ride, the country presented a lacustrine appearance; the river was deep, and nearly on a level with the surrounding country; its banks raised like a levee, and fringed with willows. Over the bordering plain were interspersed spots of prairie among fields of tule, (bulrushes,) which in this country are called tulares, and little ponds. On the opposite side, a line of timber was visible which, according to information, points out the course of the slough, which at times of high water connects with the San Joaquin river-- a large body of water in the upper part of the valley, called the Tule lakes. The river and all its sloughs are very full, and it is probable that the lake is now discharging. Here elk were frequently started, and one was shot out of a band which ran around us. On our left, the Sierra maintains its snowy height, and masses of snow appear to descend very low towards the plains; probably the late rains in the valley were snow on the mountains. We traveled 37 miles, and encamped on the river. Longitude of the camp, 120° 28' 34", and latitude, 36° 49' 12".

6th.--After having traveled fifteen miles along the river, we made an early halt, under the shade of sycamore-trees. Here we found the San Joaquin coming down from the Sierra with a westerly course, and checking our way, as all its tributaries had previously done. We had expected to raft the river; but found a good ford, and encamped on the opposite bank, where droves of wild horses were raising clouds of dust on the prairie. Columns of smoke were visible in the direction of the Tule lakes to the southward--probably kindled in the tulares by the Indians, as signals that there were strangers in the valley.

We made, on the 7th, a hard march in a cold chilly rain from morning until night--the weather so thick that we traveled by compass. This was a traverse from the San Joaquin to the waters of the Tule lakes, and our road was over a very level prairie country. We saw wolves frequently during the day, prowling about after the young antelope, which cannot run very fast. These were numerous during the day, and two were caught by the people.

Late in the afternoon we discovered timber, which was found to be groves of oak-trees on a dry arroyo. The rain, which had fallen in frequent showers, poured down in a storm at sunset, with a strong wind, which swept off the clouds, and left a clear sky. Riding on through the timber, about dark we found abundant water in small ponds, 20 to 30 yards in diameter, with clear deep water and sandy beds, bordered with bog rushes, (juncus effusus,) and a tall rush (scirpus lacustris) twelve feet high, and surrounded near the margin with willow-trees in bloom; among them one which resembled salix myricoides. The oak of the groves was the same already mentioned, with small leaves, in form like those of the white-oak, and forming, with the evergreen-oak, the characteristic trees of the valley.

8th.--After a ride of two miles through brush and open groves, we reached a large stream, called the River of the Lake, resembling in size the San Joaquin, and being about 100 yards broad. This is the principal tributary to the Tule lakes, which collect all the waters in the upper part of the valley. While we were searching for a ford, some Indians appeared on the opposite bank, and having discovered that we were not Spanish soldiers, showed us the way to a good ford several miles above.

The Indians of the Sierra make frequent descents upon the settlements west of the Coast Range, which they keep constantly swept of horses; among them are many who are called Christian Indians, being refugees from Spanish missions. Several of these incursions occurred while we were at Helvetia. Occasionally parties of soldiers follow them across the Coast Range, but never enter the Sierra.

On the opposite side we found some forty or fifty Indians, who had come to meet us from the village below. We made them some small presents, and invited them to our encampment, which, after about three miles through fine oak groves, we made on the river. We made a fort, principally on account of our animals. The Indians brought otter-skins, and several kinds of fish, and bread made of acorns, to trade. Among them were several who had come to live among these Indians when the missions were broken up, and who spoke Spanish fluently. They informed us that they were called by the Spaniards mansitos, (tame,) in distinction from the wilder tribes of the mountains. They, however, think themselves very insecure, not knowing at what unforeseen moment the sins of the latter may be visited upon them. They are dark-skinned, but handsome and intelligent Indians, and live principally on acorns and the roots of the tule, of which also their huts are made.

By observation, the latitude of the encampment is 36° 24' 50", and longitude 119° 41' 40".

9th.--For several miles we had very bad traveling over what is called rotten ground, in which the horses were frequently up to their knees. Making towards a line of timber, we found a small fordable stream, beyond which the country improved, and the grass became excellent; and crossing a number of dry and timbered arroyos, we traveled until late through open oak groves, and encamped among a collection of streams. These were running among rushes and willows; and, as usual, flocks of blackbirds announced our approach to water. We have here approached considerably nearer to the eastern Sierra, which shows very plainly, still covered with masses of snow, which yesterday and to-day has also appeared abundant on the Coast Range.

10th.--To-day we made another long journey of about forty miles, through a country uninteresting and flat, with very little grass and a sandy soil, in which several branches we crossed had lost their water. In the evening the face of the country became hilly; and, turning a few miles up towards the mountains, we found a good encampment on a pretty stream hidden among the hills, and handsomely timbered, principally with large cottonwoods, (populus, differing from any in Michaux's Sylva.) The seed-vessels of this tree were now just about bursting.

Several Indians came down the river to see us in the evening; we gave them supper, and cautioned them against stealing our horses; which they promised not to attempt.

11th.--A broad trail along the river here takes out among the hills. "Buen camino," (good road,) said one of the Indians, of whom we had inquired about the pass; and, following it accordingly, it conducted us beautifully through a very broken country, by an excellent way, which, otherwise, we should have found extremely bad. Taken separately, the hills present smooth and graceful outlines, but, together, make bad traveling ground. Instead of grass, the whole face of the country is closely covered with erodium cicutarium, here only two or three inches high. Its height and beauty varied in a remarkable manner with the locality, being, in many low places which we passed during the day, around streams and springs, two and three feet high. The country had now assumed a character of aridity; and the luxuriant green of these little streams, wooded with willow, oak, or sycamore, looked very refreshing among the sandy hills.

In the evening we encamped on a large creek, with abundant water. I noticed here in bloom, for the first time since leaving the Arkansas waters, the Miribilis Jalapa.

12th.--Along our road to-day the country was altogether sandy, and vegetation meager. Ephedra occidentalis, which we had first seen in the neighborhood of the Pyramid lake, made its appearance here, and in the course of the day became very abundant, and in large bushes. Towards the close of the afternoon, we reached a tolerably large river, which empties into a small lake at the head of the valley; it is about thirty-five yards wide, with a stony and gravelly bed, and the swiftest stream we have crossed since leaving the bay. The bottoms produced no grass, though well timbered with willow and cottonwood; and, after ascending several miles, we made a late encampment on a little bottom, with scanty grass. In greater part, the vegetation along our road consisted now of rare and unusual plants, among which many were entirely new.

Along the bottoms were thickets consisting of several varieties of shrubs, which made here their first appearance; and among these was Garrya elliptica, (Lindley,) a small tree belonging to a very peculiar natural order, and, in its general appearance, (growing in thickets,) resembling willow. It now became common along the streams, frequently supplying the place of salix longifolia.

13th.--The water was low, and a few miles above we forded the river at a rapid, and marched in a southeasterly direction over a less broken country. The mountains were now very near, occasionally looming out through fog. In a few hours we reached the bottom of a creek without water, over which the sandy beds were dispersed in many branches. Immediately where we struck it, the timber terminated; and below, to the right, it was a broad bed of dry and bare sands. There were many tracks of Indians and horses imprinted in the sand, which, with other indications, informed us was the creek issuing from the pass, and which we have called Pass creek. We ascended a trail for a few miles along the creek, and suddenly found a stream of water five feet wide, running with a lively current, but losing itself almost immediately. This little stream showed plainly the manner in which the mountain waters lose themselves in sand at the eastern foot of the Sierra, leaving only a parched desert and arid plains beyond. The stream enlarged rapidly, and the timber became abundant as we ascended.

A new species of pine made its appearance, with several kinds of oaks, and a variety of trees; and the country changing its appearance suddenly and entirely, we found ourselves again traveling among the old orchard-like places. Here we selected a delightful encampment in a handsome green oak hollow, where among the open bolls of the trees was an abundant sward of grass and pea-vines. In the evening a Christian Indian rode into the camp, well dressed, with long spurs, and a sombreo, and speaking Spanish fluently. It was an unexpected apparition, and a strange and pleasant sight in this desolate gorge of a mountain--an Indian face, Spanish costume, jingling spurs, and horse equipped after the Spanish manner. He informed me that he belonged to one of the Spanish missions to the south, distant two or three days' ride, and that he had obtained from the priests leave to spend a few days with his relations in the Sierra. Having seen us enter the pass, he had come down to visit us. He appeared familiarly acquainted with the country, and gave me definite and clear information in regard to the desert region east of the mountains. I had entered the pass with a strong disposition to vary my route, and to travel directly across towards the Great Salt lake, in the view of obtaining some acquaintance with the interior of the Great Basin, while pursuing a direct course for the frontier; but his representation, which described it as an arid and barren desert, that had repulsed by its sterility all the attempts of the Indians to penetrate it, determined me for the present to relinquish the plan, and agreeably to his advice, after crossing the Sierra, continue our intended route along its eastern base to the Spanish trail. By this route, a party of six Indians, who had come from a great river in the eastern part of the desert to trade with his people, had just started on their return. He would himself return the next day to San Fernando, and as our roads would be the same for two days, he offered his services to conduct us so far on our way. His offer was gladly accepted. The fog which had somewhat interfered with views in the valley, had entirely passed off, and left a clear sky. That which had enveloped us in the neighborhood of the pass proceeded evidently from fires kindled among the tulares by Indians living near the lakes, and which were intended to warn those in the mountains that there were strangers in the valley. Our position was in latitude 35° 17' 12", and longitude 118° 35' 03".

14th.--Our guide joined us this morning on the trail; and, arriving in a short distance at an open bottom where the creek forked, we continued up the right-hand branch, which was enriched by a profusion of flowers, and handsomely wooded with sycamore, oaks, cottonwood, and willow, with other trees, and some shrubby plants. In its long strings of balls, this sycamore differs from that of the United States, and is the platanus occidentalus of Hooker--a new species recently described among the plants collected in the voyage of the Sulphur. The cottonwood varied its foliage with white tufts, and the feathery seeds were flying plentifully through the air. Gooseberries, nearly ripe, were very abundant in the mountains; and as we passed the dividing grounds, which were not very easy to ascertain, the air was filled with perfume, as if we were entering a highly cultivated garden; and, instead of green, our pathway and the mountain sides were covered with fields of yellow flowers, which here was the prevailing color. Our journey to-day was in the midst of an advanced spring, whose green and floral beauty offered a delightful contrast to the sandy valley we had just left. All the day, snow was in sight on the butte of the mountain, which frowned down upon us on the right; but we beheld it now with feelings of pleasant security, as we rode along between green trees, and on flowers, with hummingbirds and other feathered friends of the traveler enlivening the serene spring air. As we reached the summit of this beautiful pass, and obtained a view into the eastern country, we saw at once that here was the place to take leave of all such pleasant scenes as those around us. The distant mountains were now bald rocks again, and below the land had any color but green. Taking into consideration the nature of the Sierra Nevada, we found this pass an excellent one for horses; and with a little labor, or perhaps with a more perfect examination of the localities, it might be made sufficiently practicable for wagons. Its latitude and longitude may be considered that of our last encampment, only a few miles distant. The elevation was not taken--our half-wild cavalcade making it troublesome to halt before night, when once started.

We here left the waters of the bay of San Francisco, and, though forced upon them contrary to my intentions, I cannot regret the necessity which occasioned the deviation. It made me well acquainted with the great range of the Sierra Nevada of the Alta California, and showed that this broad and elevated snowy ridge was a continuation of the Cascade Range of Oregon, between which and the ocean there is still another and a lower range, parallel to the former and to the coast, and which may be called the Coast Range. It also made me well acquainted with the basin of the San Francisco bay, and with the two pretty rivers and their valleys (the Sacramento and San Joaquin) which are tributary to that bay, and cleared up some points in geography on which error had long prevailed. It had been constantly represented, as I have already stated, that the bay of San Francisco opened far into the interior, by some river coming down from the base of the Rocky mountains, and upon which supposed stream the name of Rio Buenaventura had been bestowed. Our observations of the Sierra Nevada, in the long distance from the head of the Sacramento, to the head of the San Joaquin, and of the valley below it, which collects all the waters of the San Francisco bay, show that this neither is nor can be the case. No river from the interior does, or can, cross the Sierra Nevada--itself more lofty than the Rocky mountains; and as to the Buenaventura, the mouth of which seen on the coast gave the idea and the name of the reputed great river, it is, in fact, a small stream of no consequence, not only below the Sierra Nevada, but actually below the Coast Range--taking its rise within half a degree of the ocean, running parallel to it for about two degrees, and then falling into the Pacific near Monterey. There is no opening from the bay of San Francisco into the interior of the continent. The two rivers which flow into it are comparatively short, and not perpendicular to the coast, but lateral to it, and having their heads towards Oregon and southern California. They open lines of communication north and south, and not eastwardly; and thus this want of interior communication from the San Francisco bay, now fully ascertained, gives great additional value to the Columbia, which stands alone as the only great river on the Pacific slope of our continent which leads from the ocean to the Rocky mountains, and opens a line of communication from the sea to the valley of the Mississippi.

Four companeros joined our guide at the pass; and two going back at noon, the others continued on in company. Descending from the hills, we reached a country of fine grass, where the erodium cicutarium finally disappeared, giving place to an excellent quality of bunch-grass. Passing by some springs where there was a rich sward of grass among groves of large black-oak, we rode over a plain on which the guide pointed out a spot where a refugee Christian Indian had been killed by a party of soldiers which had unexpectedly penetrated into the mountains. Crossing a low sierra, and descending a hollow where a spring gushed out, we were struck by the sudden appearance of yucca trees, which gave a strange and southern character to the country, and suited well with the dry and desert region we were approaching. Associated with the idea of barren sands, their stiff and ungraceful form makes them to the traveler the most repulsive tree in the vegetable kingdom. Following the hollow, we shortly came upon a creek timbered with large black-oak, which yet had not put forth a leaf. There was a small rivulet of running water, with good grass.

15th.--The Indians who had accompanied the guide returned this morning, and I purchased from them a Spanish saddle and long spurs, as reminiscences of the time; and for a few yards of scarlet cloth they gave me a horse, which afterwards became food for other Indians.

We continued a short distance down the creek, in which our guide informed us that the water very soon disappeared, and turned directly to the southward along the foot of the mountain; the trail on which we rode appearing to describe the eastern limit of travel, where water and grass terminated. Crossing a low spur, which bordered the creek, we descended to a kind of plain among the lower spurs, the desert being in full view on our left, apparently illimitable. A hot mist lay over it to-day, through which it had a white and glistening appearance; here and there a few dry- looking buttes and isolated black ridges rose suddenly upon it. "There," said our guide, stretching out his hand towards it, "there are the great llanos, (plains,) no hay agua; no hay zacate-- nada: there is neither water nor grass--nothing; every animal that goes upon them, dies." It was indeed dismal to look upon, and to conceive so great a change in so short a distance. One might travel the world over, without finding a valley more fresh and verdant--more floral and sylvan-- more alive with birds and animals--more bounteously watered--than we had left in the San Joaquin: here within a few miles' ride, a vast desert plain spread before us, from which the boldest traveler turned away in despair.

Directly in front of us, at some distance to the southward, and running out in an easterly direction from the mountains, stretched a sierra, having at the eastern end (perhaps 50 miles distant) some snowy peaks, on which, by the information of our guide, snow rested all the year.

Our cavalcade made a strange and grotesque appearance; and it was impossible to avoid reflecting upon our position and composition in this remote solitude. Within two degrees of the Pacific ocean--already far south of the latitude of Monterey--and still forced on south by a desert on one hand, and a mountain range on the other--guided by a civilized Indian, attended by two wild ones from the Sierra--a Chinook from the Columbia, and our mixture of American, French, German--all armed--four or five languages heard at once--above a hundred horses and mules, half wild- -American, Spanish, and Indian dresses and equipments intermingled--such was our composition. Our march was a sort of procession. Scouts ahead and on the flanks; a front and rear division; the pack-animals, baggage, and horned-cattle in the centre; and the whole stretching a quarter of a mile along our dreary path. In this form we journeyed, looking more as if we belonged to Asia than to the United States of America.

We continued in a southerly direction across the plain, to which, as well as to all the country, so far as we could see, the yucca trees gave a strange and singular character. Several new plants appeared, among which was a zygophyllaceous shrub, (zygophyllum Californicum, Torr. and Frem.,) sometimes ten feet in height; in form, and in the pliancy of its branches, it is rather a graceful plant. Its leaves are small, covered with a resinous substance; and, particularly when bruised and crushed, exhale a singular but very agreeable and refreshing odor. This shrub and the yucca, with many varieties of cactus, make the characteristic features in the vegetation for a long distance to the eastward. Along the foot of the mountain, 20 miles to the southward, red stripes of flowers were visible during the morning, which we supposed to be variegated sandstones. We rode rapidly during the day, and in the afternoon emerged from the yucca forest at the foot of an outlier of the Sierra before us, and came among the fields of flowers we had seen in the morning, which consisted principally of the rich orange-colored California poppy, mingled with other flowers of brighter tints. Reaching the top of the spur, which was covered with fine bunch-grass, and where the hills were very green, our guide pointed to a small hollow in the mountain before us, saying, "a este piedra hay agua." He appeared to know every nook in the country. We continued our beautiful road, and reached a spring in the slope at the foot of the ridge, running in a green ravine, among granite boulders; here nightshade, and borders of buckwheat, with their white blossoms around the granite rocks, attracted our notice as familiar plants. Several antelopes were seen among the hills, and some large hares. Men were sent back this evening in search of a wild mule with a valuable pack, which had managed (as they frequently do) to hide itself along the road.

By observation, the latitude of the camp is 34° 41' 42", and longitude 118° 20' 00". The next day the men returned with the mule.

17th.--Crossing the ridge by a beautiful pass of hollows, where several deer broke out of the thickets, we emerged at a small salt lake in a vallon lying nearly east and west, where a trail from the mission of San Buenaventura comes in. The lake is about 1,200 yards in diameter; surrounded on the margin by a white salty border, which, by the smell, reminded us slightly of Lake Abert. There are some cottonwoods, with willow and elder, around the lake; and the water is a little salt, although not entirely unfit for drinking. Here we turned directly to the eastward along the trail, which, from being seldom used, is almost imperceptible; and, after traveling a few miles, our guide halted, and, pointing to the hardly visible trail, "aqui es camino," said he, "no se pierde--va siempre." He pointed out a black butte on the plain at the foot of the mountain, where we would find water to encamp at night; and, giving him a present of knives and scarlet cloth, we shook hands and parted. He bore off south, and in a day's ride would arrive at San Fernando, one of several missions in this part of California, where the country is so beautiful that it is considered a paradise, and the name of its principal town (Puebla de los Angeles) would make it angelic. We continued on through a succession of valleys, and came into a most beautiful spot of flower fields; instead of green, the hills were purple and orange, with unbroken beds, into which each color was separately gathered. A pale straw-color, with a bright yellow, the rich red orange of the poppy mingled with fields of purple, covered the spot with a floral beauty; and, on the border of the sandy deserts, seemed to invite the traveler to go no farther. Riding along through the perfumed air, we soon after entered a defile overgrown with the ominous artemisia tridentata, which conducted us into a sandy plain covered more or less densely with forests of yucca.

Having now the snowy ridge on our right, we continued our way towards a dark butte, belonging to a low sierra on the plain, and which our guide had pointed out for a landmark. Late in the day, the familiar growth of cottonwood, a line of which was visible ahead, indicated our approach to a creek, which we reached where the water spread out into sands, and a little below sank entirely. Here our guide had intended we should pass the night; but there was not a blade of grass, and, hoping to find nearer the mountain a little for the night, we turned up the stream. A hundred yards above, we found the creek a fine stream, sixteen feet wide, with a swift current. A dark night overtook us when we reached the hills at the foot of the ridge, and we were obliged to encamp without grass; tying up what animals we could secure in the darkness, the greater part of the wild ones having free range for the night. Here the stream was two feet deep, swift and clear, issuing from a neighboring snow peak. A few miles before reaching this creek, we had crossed a broad dry riverbed, which, nearer the hills, the hunters had found a bold and handsome stream.

18th.--Some parties were engaged in hunting up the scattered horses, and others in searching for grass above; both were successful, and late in the day we encamped among some spring-heads of the river, in a hollow which was covered with only tolerably good grasses, the lower ground being entirely overgrown with large bunches of the coarse stiff grass, (carex sitchensis.)

Our latitude, by observation, was 34° 27' 03", and longitude 117° 13' 00".

Traveling close along the mountain, we followed up, in the afternoon of the 19th, another stream, in hopes to find a grass-patch like that of the previous day, but were deceived; except some scattered bunch-grass, there was nothing but rock and sand; and even the fertility of the mountain seemed withered by the air of the desert. Among the few trees was the nut pine, (pinus monophyllus.)

Our road the next day was still in an easterly direction along the ridge, over very bad traveling ground, broken and confounded with crippled trees and shrubs; and, after a difficult march of eighteen miles, a general shout announced that we had struck the great object of our search--THE SPANISH TRAIL --which here was running directly north. The road itself, and its course, were equally happy discoveries to us. Since the middle of December we had continually been forced south by mountains and by deserts, and now would have to make six degrees of northing, to regain the latitude on which we wished to cross the Rocky mountains. The course of the road, therefore, was what we wanted; and, once more, we felt like going homewards. A road to travel on, and the right course to go, were joyful consolations to us; and our animals enjoyed the beaten track like ourselves. Relieved from the rocks and brush, our wild mules started off at a rapid rate, and in fifteen miles we reached a considerable river, timbered with cottonwood and willow, where we found a bottom of tolerable grass. As the animals had suffered a great deal in the last few days, I remained here all next day, to allow them the necessary repose; and it was now necessary, at every favorable place, to make a little halt. Between us and the Colorado river we were aware that the country was extremely poor in grass, and scarce for water, there being many jornadas, (days' journey,) or long stretches of forty to sixty miles, without water, where the road was marked by bones of animals.

Although in California we had met with people who had passed over this trail, we had been able to obtain no correct information about it; and the greater part of what we had heard was found to be only a tissue of falsehoods. The rivers that we found on it were never mentioned, and others, particularly described in name and locality, were subsequently seen in another part of the country. It was described as a tolerably good sandy road, with so little rock as scarcely to require the animals to be shod; and we found it the roughest and rockiest road we had ever seen in the country, and which nearly destroyed our band of fine mules and horses. Many animals are destroyed on it every year by a disease called the foot- evil; and a traveler should never venture on it without having his animals well shod, and also carrying extra shoes.

Latitude 34° 34' 11"; and longitude 117° 13' 00".

The morning of the 22d was clear and bright, and a snowy peak to the southward shone out high and sharply defined. As has been usual since we crossed the mountains and descended into the hot plains, we had a gale of wind. We traveled down the right bank of the stream, over sands which are somewhat loose, and have no verdure, but are occupied by various shrubs. A clear bold stream, 60 feet wide, and several feet deep, had a strange appearance, running between perfectly naked banks of sand. The eye, however, is somewhat relieved by willows, and the beautiful green of the sweet cottonwoods with which it is well wooded. As we followed along its course, the river, instead of growing constantly larger, gradually dwindled away, as it was absorbed by the sand. We were now careful to take the old camping-places of the annual Santa Fé caravans, which, luckily for us, had not yet made their yearly passage. A drove of several thousand horses and mules would entirely have swept away the scanty grass at the watering places, and we should have been obliged to leave the road to obtain subsistence for our animals. After riding 20 miles in a north- easterly direction, we found an old encampment, where we halted.

By observation, the elevation of this encampment is 2,250 feet.

23d.--The trail followed still along the river, which, in the course of the morning, entirely disappeared. We continued along the dry bed, in which, after an interval of about 16 miles, the water reappeared in some low places, well timbered with cottonwood and willow, where was another of the customary camping-grounds. Here a party of six Indians came into camp, poor and hungry, and quite in keeping with the character of the country. Their arms were bows of unusual length, and each had a large gourd, strengthened with meshes of cord, in which he carried water. They proved to be the Mohahve Indians mentioned by our recent guide; and from one of them, who spoke Spanish fluently, I obtained some interesting information, which I would be glad to introduce here. An account of the people inhabiting this region would undoubtedly possess interest for the civilized world. Our journey homewards was fruitful in incident; and the country through which we traveled, although a desert, afforded much to excite the curiosity of the botanist; but limited time, and the rapidly advancing season for active operations, oblige me to omit all extended descriptions, and hurry briefly to the conclusion of this report.

The Indian who spoke Spanish had been educated for a number of years at one of the Spanish missions, and, at the breaking up of those establishments, had returned to the mountains, where he had been found by a party of Mohahve (sometimes called Amuchaba) Indians, among whom he had ever since resided.

He spoke of the leader of the present party as "mi amo," (my master.) He said they lived upon a large river in the southeast, which the "soldiers called the Rio Colorado;" but that, formerly, a portion of them lived upon this river, and among the mountains which had bounded the river valley to the northward during the day, and that here along the river they had raised various kinds of melons. They sometimes came over to trade with the Indians of the Sierra, bringing with them blankets and goods manufactured by the Monquis and other Colorado Indians. They rarely carried home horses, on account of the difficulty of getting them across the desert, and of guarding them afterwards from the Pa-utah Indians, who inhabit the Sierra, at the head of the Rio Virgen, (river of the Virgin.)

He informed us that, a short distance below, this river finally disappeared. The two different portions in which water is found had received from the priests two different names; and subsequently I heard it called by the Spaniards the Rio de las Animas, but on the map we have called it the Mohahve river.

24th.--We continued down the stream (or rather its bed) for about eight miles, where there was water still in several holes, and encamped. The caravans sometimes continued below, to the end of the river, from which there is a very long jornada of perhaps 60 miles, without water. Here a singular and new species of acacia, with spiral pods or seed- vessels, made its first appearance; becoming henceforward, for a considerable distance, the characteristic tree. It was here comparatively large, being about 20 feet in height, with a full and spreading top, the lower branches declining towards the ground. It afterwards occurred of smaller size, frequently in groves, and is very fragrant. It has been called by Dr. Torrey, spirolobium odoratum. The zygophyllaceous shrub had been constantly characteristic of the plains along the river; and here, among many new plants, a new and very remarkable species of eriogonum (eriogonum inflatum, Tor. & Frem.) made its first appearance.

Our cattle had become so tired and poor by this fatiguing traveling, that three of them were killed here, and the meat dried. The Indians had now an occasion for a great feast and were occupied the remainder of the day and all night in cooking and eating. There was no part of the animal for which they did not find some use, except the bones. In the afternoon we were surprised by the sudden appearance in the camp of two Mexicans--a man and a boy. The name of the man was Andreas Fuentes; and that of the boy, (a handsome lad, 11 years old,) Pablo Hernandez. They belonged to a party consisting of six persons, the remaining four being the wife of Fuentes, and the father and mother of Pablo, and Santiago Giacome, a resident of New Mexico. With a cavalcade of about thirty horses, they had come out from Puebla de los Angeles, near the coast, under the guidance of Giacome, in advance of the great caravan, in order to travel more at leisure, and obtain better grass. Having advanced as far into the desert as was considered consistent with their safety, they halted at the Archilette, one of the customary camping-grounds, about 80 miles from our encampment, where there is a spring of good water, with sufficient grass; and concluded to await there the arrival of the great caravan. Several Indians were soon discovered lurking about the camp, who, in a day or two after, came in, and, after behaving in a very friendly manner, took their leave, without awakening any suspicions. Their deportment begat a security which proved fatal. In a few days afterwards, suddenly a party of about one hundred Indians appeared in sight, advancing towards the camp. It was too late, or they seemed not to have presence of mind to take proper measures of safety; and the Indians charged down into their camp, shouting as they advanced, and discharging flights of arrows. Pablo and Fuentes were on horse-guard at the time, and mounted according to the custom of the country. One of the principal objects of the Indians was to get possession of the horses, and part of them immediately surrounded the band; but, in obedience to the shouts of Giacome, Fuentes drove the animals over and through the assailants, in spite of their arrows; and, abandoning the rest to their fate, carried them off at speed across the plain. Knowing that they would be pursued by the Indians, without making any halt except to shift their saddles to other horses, they drove them on for about sixty miles, and this morning left them at a watering-place on the trail, called Agua de Tomaso. Without giving themselves any time for rest, they hurried on, hoping to meet the Spanish caravan, when they discovered my camp. I received them kindly, taking them into my own mess, and promised them such aid as circumstances might put it in my power to give.

25th.--We left the river abruptly, and, turning to the north, regained in a few miles the main trail, (which had left the river sooner than ourselves,) and continued our way across a lower ridge of the mountain, through a miserable tract of sand and gravel. We crossed at intervals the broad beds of dry gullies, where in the seasons of rains and melting snows there would be brooks or rivulets: and at one of these, where there was no indication of water, were several freshly-dug holes, in which there was water at the depth of two feet. These holes had been dug by the wolves, whose keen sense of smell had scented the water under the dry sand. They were nice little wells, narrow, and dug straight down; and we got pleasant water out of them.

The country had now assumed the character of an elevated and mountainous desert; its general features being black, rocky ridges, bald, and destitute of timber, with sandy basins between. Where the sides of these ridges are washed by gullies, the plains below are strewed with beds of large pebbles or rolled stones, destructive to our soft-footed animals, accustomed to the soft plains of the Sacramento valley. Through these sandy basins sometimes struggled a scanty stream, or occurred a hole of water, which furnished camping-grounds for travelers. Frequently in our journey across, snow was visible on the surrounding mountains; but their waters rarely reached the sandy plain below, where we toiled along, oppressed with thirst and a burning sun. But, throughout this nakedness of sand and gravel, were many beautiful plants and flowering shrubs, which occurred in many new species, and with greater variety than we had been accustomed to see in the most luxuriant prairie countries; this was a peculiarity of this desert. Even where no grass would take root, the naked sand would bloom with some rich and rare flower, which found its appropriate home in the arid and barren spot.

Scattered over the plain, and tolerably abundant, was a handsome leguminous shrub, three or four feet high, with fine bright purple flowers. It is a new psoralea, and occurred frequently henceforward along our road.

Beyond the first ridge, our road bore a little to the east of north, towards a gap in a higher line of mountains; and, after traveling about 25 miles, we arrived at the Agua de Tomaso--the spring where the horses had been left; but, as we expected, they were gone. A brief examination of the ground convinced us that they had been driven off by the Indians. Carson and Godey volunteered, with the Mexican, to pursue them; and, well mounted, the three set off on the trail. At this stopping- place there are a few bushes, and a very little grass. Its water was a pool; but near by was a spring, which had been dug out by Indians or travelers. Its water was cool--a great refreshment to us under a burning sun.

In the evening Fuentes returned, his horse having failed; but Carson and Godey had continued the pursuit.

I observed to-night an occultation of a2 Cancri, at the dark limb of the moon, which gives for the longitude of the place 116° 23' 28"; the latitude, by observation, is 35° 13' 08". From Helvetia to this place, the positions along the intervening line are laid down, with the longitudes obtained from the chronometer, which appears to have retained its rate remarkably well; but henceforward, to the end of our journey, the few longitudes given are absolute, depending upon a subsequent occultation and eclipses of the satellites.

In the afternoon of the next day, a war-whoop was heard, such as Indians make when returning from a victorious enterprise; and soon Carson and Godey appeared, driving before them a band of horses, recognised by Fuentes to be part of those they had lost. Two bloody scalps, dangling from the end of Godey's gun, announced that they had overtaken the Indians as well as the horses. They informed us, that after Fuentes left them, from the failure of his horse, they continued the pursuit alone, and towards night-fall entered the mountains, into which the trail led. After sunset the moon gave light, and they followed the trail by moonshine until late in the night, when it entered a narrow defile, and was difficult to follow. Afraid of losing it in the darkness of the defile, they tied up their horses, struck no fire, and lay down to sleep, in silence and in darkness. Here they lay from midnight until morning. At daylight they resumed the pursuit, and about sunrise discovered the horses; and, immediately dismounting and tying up their own, they crept cautiously to a rising ground which intervened, from the crest of which they perceived the encampment of four lodges close by. They proceeded quietly, and had got within 30 or 40 yards of their object, when a movement among the horses discovered them to the Indians. Giving the war-shout, they instantly charged into the camp, regardless of the number which the four lodges would imply. The Indians received them with a flight of arrows shot from their long-bows, one of which passed through Godey's shirt-collar, barely missing the neck: our men fired their rifles upon a steady aim, and rushed in. Two Indians were stretched upon the ground, fatally pierced with bullets: the rest fled, except a little lad that was captured. The scalps of the fallen were instantly stripped off; but in the process, one of them, who had two balls through his body, sprang to his feet, the blood streaming from his skinned head, and uttering a hideous howl. An old squaw, possibly his mother, stopped and looked back from the mountainsides she was climbing, threatening and lamenting. The frightful spectacle appalled the stout hearts of our men; but they did what humanity required, and quickly terminated the agonies of the gory savage. They were now masters of the camp, which was a pretty little recess in the mountain, with a fine spring, and apparently safe from all invasion. Great preparations had been made to feast a large party, for it was a very proper place to rendezvous, and for the celebration of such orgies as robbers of the desert would delight in. Several of the best horses had been killed, skinned, and cut up; for the Indians living in mountains, and only coming into the plains to rob and murder, make no other use of horses than to eat them. Large earthen vessels were on the fire, boiling and stewing the horse-beef; and several baskets, containing 50 or 60 pairs of moccasins, indicated the presence, or expectation, of a considerable party. They released the boy, who had given strong evidence of the stoicism, or something else, of the savage character, in commencing his breakfast upon a horse's head, as soon as he found he was not to be killed, but only tied as a prisoner. Their object accomplished, our men gathered up all the surviving horses, fifteen in number, returned upon their trail, and rejoined us, at our camp, in the afternoon of the same day. They had rode about 100 miles, in the pursuit and return, and all in 30 hours. The time, place, object, and numbers considered, this expedition of Carson and Godey may be considered among the boldest and most disinterested which the annals of western adventure, so full of daring deeds, can present. Two men, in a savage desert, pursue day and night an unknown body of Indians, into the defile of an unknown mountain--attack them on sight, without counting numbers--and defeat them in an instant-- and for what? To punish the robbers of the desert, and to avenge the wrongs of Mexicans whom they did not know. I repeat: it was Carson and Godey who did this--the former an American, born in the Boonslick county of Missouri; the latter a Frenchman, born in St. Louis,--and both trained to western enterprise from early life.

By the information of Fuentes, we had now to make a long stretch of 40 or 50 miles across a plain which lay between us and the next possible camp; and we resumed our journey late in the afternoon, with the intention of traveling through the night, and avoiding the excessive heat of the day, which was oppressive to our animals. For several hours we traveled across a high plain, passing, at the opposite side, through a canon by the bed of a creek, running northwardly into a small lake beyond, and both of them being dry. We had a warm, moonshiny night; and, traveling directly towards the north-star, we journeyed now across an open plain, between mountain- ridges--that on the left being broken, rocky, and bald, according to Carson and Godey, who had entered here in pursuit of the horses. The plain appeared covered principally with the zygophyllum Californicum, already mentioned; and the line of our road was marked by the skeletons of horses, which were strewed to considerable breadth over the plain. We were always warned on entering one of these long stretches, by the bones of these animals, which had perished before they could reach the water. About midnight we reached a considerable stream-bed, now dry--the discharge of the waters of this basin, (when it collected any)--down which we descended, in a northwesterly direction. The creek-bed was overgrown with shrubbery, and several hours before day it brought us to the entrance of a canon, where we found water, and encamped. This word canon is used by the Spaniards to signify a defile or gorge in a creek or river, where high rocks press in close, and make a narrow way, usually difficult, and often impossible to be passed.

In the morning we found that we had a very poor camping-ground--a swampy, salty spot, with a little long, unwholesome grass; and the water, which rose in springs, being useful only to wet the mouth, but entirely too salt to drink. All around was sand and rocks, and skeletons of horses which had not been able to find support for their lives. As we were about to start, we found, at the distance of a few hundred yards, among the hills to the southward, a spring of tolerably good water, which was a relief to ourselves; but the place was too poor to remain long, and therefore we continued on this morning. On the creek were thickets of spirolobium odoratum (acacia) in bloom, and very fragrant.

Passing through the canon, we entered another sandy basin, through which the dry stream-bed continued its north-westerly course, in which direction appeared a high snowy mountain.

We traveled through a barren district, where a heavy gale was blowing about the loose sand, and, after a ride of eight miles, reached a large creek of salt and bitter water, running in a westerly direction, to receive the stream-bed we had left. It is called by the Spaniards Amargosa--the bitter-water of the desert. Where we struck it, the stream bends; and we continued in a northerly course up the ravine of its valley, passing on the way a fork from the right, near which occurred a bed of plants, consisting of a remarkable new genus of cruciferæ.

Gradually ascending, the ravine opened into a green valley, where, at the foot of the mountain, were springs of excellent water. We encamped among groves of the new acacia, and there was an abundance of good grass for the animals.

This was the best camping-ground we had seen since we struck the Spanish trail. The day's journey was about twelve miles.

29th.--To-day we had to reach the Archilette, distant seven miles, where the Mexican party had been attacked, and, leaving our encampment early, we traversed a part of the desert the most sterile and repulsive we had yet seen. Its prominent features were dark sierras, naked and dry; on the plains a few straggling shrubs--among them, cactus of several varieties. Fuentes pointed out one called by the Spaniards bisnada, which has a juicy pulp, slightly acid, and is eaten by the traveler to allay thirst. Our course was generally north; and, after crossing an intervening ridge, we descended into a sandy plain, or basin, in the middle of which was the grassy spot, with its springs and willow bushes, which constitutes a camping-place in the desert, and is called the Archilette. The dead silence of the place was ominous; and, galloping rapidly up, we found only the corpses of the two men: every thing else was gone. They were naked, mutilated, and pierced with arrows. Hernandez had evidently fought, and with desperation. He lay in advance of the willow half-faced tent, which sheltered his family, as if he had come out to meet danger, and to repulse it from that asylum. One of his hands, and both his legs, had been cut off. Giacome, who was a large and strong- looking man, was lying in one of the willow shelters, pierced with arrows.

Of the women no trace could be found, and it was evident they had been carried off captive. A little lap-dog, which had belonged to Pablo's mother, remained with the dead bodies, and was frantic with joy at seeing Pablo; he, poor child, was frantic with grief, and filled the air with lamentations for his father and mother. Mi Padre! Mi Madre!--was his incessant cry. When we beheld this pitiable sight, and pictured to ourselves the fate of the two women, carried off by savages so brutal and so loathsome, all compunction for the scalped-alive Indian ceased; and we rejoiced that Carson and Godey had been able to give so useful a lesson to these American Arabs who lie in wait to murder and plunder the innocent traveler.

We were all too much affected by the sad feelings which the place inspired, to remain an unnecessary moment. The night we were obliged to pass there. Early in the morning we left it, having first written a brief account of what had happened, and put it in the cleft of a pole planted at the spring, that the approaching caravan might learn the fate of their friends. In commemoration of the event, we called the place Ague de Hernandez--Hernandez's spring. By observation, its latitude was 35° 51' 21".

30th.--We continued our journey over a district similar to that of the day before. From the sandy basin, in which was the spring, we entered another basin of the same character, surrounded everywhere by mountains. Before us stretched a high range, rising still higher to the left, and terminating in a snowy mountain.

After a day's march of 24 miles, we reached at evening the bed of a stream from which the water had disappeared, a little only remaining in holes, which we increased by digging; and about a mile above, the stream, not yet entirely sunk, was spread out over the sands, affording a little water for the animals. The stream came out of the mountains on the left, very slightly wooded with cottonwood, willow, and acacia, and a few dwarf-oaks; and grass was nearly as scarce as water. A plant with showy yellow flowers (Stanleya integrifolia) occurred abundantly at intervals for the last two days, and eriogonum inflatum was among the characteristic plants.

MAY.

1st.--The air is rough, and overcoats pleasant. The sky is blue, and the day bright. Our road was over a plain, towards the foot of the mountain; zygophyllum Californicum, now in bloom, with a small yellow flower, is characteristic of the country; and cacti were very abundant, and in rich fresh bloom, which wonderfully ornaments this poor country. We encamped at a spring in the pass, which had been the site of an old village. Here we found excellent grass, but very little water. We dug out the old spring, and watered some of our animals. The mountain here was wooded very slightly with the nut-pine, cedars, and a dwarf species of oak; and among the shrubs were Purshia tridentata, artemisia, and ephedra occidentalis. The numerous shrubs which constitute the vegetation of the plains are now in bloom, with flowers of white, yellow, red, and purple. The continual rocks, and want of water and grass, began to be very hard on our mules and horses; but the principal loss is occasioned by their crippled feet, the greater part of those left being in excellent order, and scarcely a day passes without some loss; and, one by one, Fuentes' horses are constantly dropping behind. Whenever they give out, he dismounts and cuts off their tails and manes, to make saddle- girths--the last advantage one can gain from them.

The next day, in a short but rough ride of 12 miles, we crossed the mountain; and, descending to a small valley plain, encamped at the foot of the ridge, on the bed of a creek, and found good grass in sufficient quantity, and abundance of water in holes. The ridge is extremely rugged and broken, presenting on this side a continued precipice, and probably affords very few passes. Many digger tracks were seen around us, but no Indians were visible.

3d.--After a day's journey of 18 miles, in a northeasterly direction, we encamped in the midst of another very large basin, at a camping ground called las Vegas--a term which the Spaniards use to signify fertile or marshy plains, in contradistinction to llanos, which they apply to dry and sterile plains. Two narrow streams of clear water, four or five feet deep, gush suddenly, with a quick current, from two singularly large springs; these, and other waters of the basin, pass out in a gap to the eastward. The taste of the water is good, but rather too warm to be agreeable; the temperature being 71° in the one, and 73° in the other. They, however, afford a delightful bathing-place.

4th.--We started this morning earlier than usual, traveling in a northeasterly direction across the plain. The new acacia (spirolobium odoratum) has now become the characteristic tree of the country; it is in bloom, and its blossoms are very fragrant. The day was still, and the heat, which soon became very oppressive, appeared to bring out strongly the refreshing scent of the zygophyllaceous shrubs and the sweet perfume of the acacia. The snowy ridge we had just crossed looked out conspicuously in the northwest. In about five hours' ride, we crossed a gap in the surrounding ridge, and the appearance of skeletons of horses very soon warned us that we were engaged in another dry jornada, which proved the longest we had made in all our journey--between fifty and sixty miles without a drop of water.

Travelers through countries affording water and timber can have no conception of our intolerable thirst while journeying over the hot yellow sands of this elevated country, where the heated air seems to be entirely deprived of moisture. We ate occasionally the bisnada, and moistened our mouths with the acid of the sour dock, (rumex venosus.) Hourly expecting to find water, we continued to press on until towards midnight, when, after a hard and uninterrupted march of 16 hours, our wild mules began running ahead; and in a mile or two we came to a bold running stream--so keen is the sense of that animal, in these desert regions, in scenting at a distance this necessary of life.

According to the information we had received, Sevier river was a tributary of the Colorado; and this, accordingly, should have been one of its affluents. It proved to be the Rio de los Angeles, (river of the Angels)--a branch of the Rio Virgen. (river of the Virgin.)

5th.--On account of our animals, it was necessary to remain to-day at this place. Indians crowded numerously around us in the morning; and we were obliged to keep arms in hand all day, to keep them out of the camp. They began to surround the horses, which, for the convenience of grass, we were guarding a little above, on the river. These were immediately driven in, and kept close to the camp.

In the darkness of the night we had made a very bad encampment, our fires being commanded by a rocky bluff within 50 yards; but, notwithstanding, we had the river and small thickets of willows on the other side. Several times during the day the camp was insulted by the Indians; but, peace being our object, I kept simply on the defensive. Some of the Indians were on the bottoms, and others haranguing us from the bluffs; and they were scattered in every direction over the hills. Their language being probably a dialect of the Utah, with the aid of signs some of our people could comprehend them very well. They were the same people who had murdered the Mexicans; and towards us their disposition was evidently hostile, nor were we well disposed towards them. They were barefooted, and nearly naked; their hair gathered up into a knot behind; and with his bow, each man carried a quiver with thirty or forty arrows partially drawn out. Besides these, each held in his hand two or three arrows for instant service. Their arrows are barbed with a very clear translucent stone, a species of opal, nearly as hard as the diamond; and, shot from their long bow, are almost as effective as a gunshot. In these Indians, I was forcibly struck by an expression of countenance resembling that in a beast of prey; and all their actions are those of wild animals. Joined to the restless motion of the eye, there is a want of mind--an absence of thought--and an action wholly by impulse, strongly expressed, and which constantly recalls the similarity.

A man who appeared to be a chief, with two or three others forced himself into the camp, bringing with him his arms, in spite of my orders to the contrary. When shown our weapons, he bored his ear with his fingers, and said he could not hear. "Why," said he, "there are none of you." Counting the people around the camp, and including in the number a mule that was being shod, he made out 22. "So many," said he, showing the number, "and we--we are a great many;" and he pointed to the hills and mountains round about. "If you have your arms," said he, twanging his bow, "we have these." I had some difficulty in restraining the people, particularly Carson, who felt an insult of this kind as much as if it had been given by a more responsible being. "Don't say that, old man," said he; "don't you say that--your life's in danger"--speaking in good English; and probably the old man was nearer to his end than he will be before he meets it.

Several animals had been necessarily left behind near the camp last night; and early in the morning, before me Indians made their appearance, several men were sent to bring them in. When I was beginning to be uneasy at their absence, they returned with information that they had been driven off from the trail by Indians; and, having followed the tracks in a short distance, they found the animals cut up and spread out upon bushes. In the evening I gave a fatigued horse to some of the Indians for a feast; and the village which carried him off refused to share with the others, who made loud complaints from the rocks of the partial distribution. Many of these Indians had long sticks, hooked at the end, which they use in hauling out lizards, and other small animals, from their holes. During the day they occasionally roasted and ate lizards at our fires. These belong to the people who are generally known under the name of Diggers; and to these I have more particularly had reference when occasionally speaking of a people whose sole occupation is to procure food sufficient to support existence. The formation here consists of fine yellow sandstone, alternating with a coarse conglomerate, in which the stones are from the size of ordinary gravel to six or eight inches in diameter. This is the formation which renders the surface of the country so rocky, and gives us now a road alternately of loose heavy sands and rolled stones, which cripple the animals in a most extraordinary manner.

On the following morning we left the Rio de los Angeles, and continued our way through the same desolate and revolting country, where lizards were the only animal, and the tracks of the lizard eaters the principal sign of human beings. After twenty miles' march through a road of hills and heavy sands, we reached the most dreary river I have ever seen--a deep rapid stream, almost a torrent, passing swiftly by, and roaring against obstructions. The banks were wooded with willow, acacia, and a frequent plant of the country already mentioned, (Garrya elliptica,) growing in thickets, resembling willow, and bearing a small pink flower. Crossing it we encamped on the left bank, where we found a very little grass. Our three remaining steers, being entirely given out, were killed here. By the boiling point, the elevation of the river here is 4,060 feet; and latitude, by observation, 36°41' 33". The stream was running towards the southwest, and appeared to come from a snowy mountain in the north. It proved to be the Rio Virgen --a tributary to the Colorado. Indians appeared in bands on the hills, but did not come into camp. For several days we continued our journey up the river, the bottoms of which were thickly overgrown with various kinds of brush; and the sandy soil was absolutely covered with the tracks of Diggers, who followed us stealthily, like a band of wolves; and we had no opportunity to leave behind, even for a few hours, the tired animals, in order that they might be brought into camp after a little repose. A horse or mule, left behind, was taken off in a moment. On the evening of the 8th, having traveled 28 miles up the river from our first encampment on it, we encamped at a little grass-plat, where a spring of cool water issued from the bluff. On the opposite side was a grove of cottonwoods at the mouth of a fork, which here enters the river. On either side the valley is bounded by ranges of mountains, everywhere high, rocky, and broken. The caravan road was lost and scattered in the sandy country, and we had been following an Indian trail up the river. The hunters the next day were sent out to reconnoitre, and in the mean time we moved about a mile farther up, where we found a good little patch of grass. There being only sufficient grass for the night, the horses were sent with a strong guard in charge of Tabeau to a neighboring hollow, where they might pasture during the day; and, to be ready in case the Indians should make any attempt on the animals, several of the best horses were picketed at the camp. In a few hours the hunters returned, having found a convenient ford in the river, and discovered the Spanish trail on the other side.

I had been engaged in arranging plants; and, fatigued with the heat of the day, I fell asleep in the afternoon, and did not awake until sundown. Presently Carson came to me, and reported that Tabeau, who early in the day had left his post, and, without my knowledge, rode back to the camp we had left, in search of a lame mule, had not returned. While we were speaking, a smoke rose suddenly from the cottonwood grove below, which plainly told us what had befallen him; it was raised to inform the surrounding Indians that a blow had been struck, and to tell them to be on their guard. Carson, with several men well mounted, was instantly sent down the river, but returned in the night without tidings of the missing man. They went to the camp we had left, but neither he nor the mule was there. Searching down the river, they found the tracks of the mule, evidently driven along by Indians, whose tracks were on each side of those made by the animal. After going several miles, they came to the mule itself, standing in some bushes, mortally wounded in the side by an arrow, and left to die, that it might be afterwards butchered for food. They also found, in another place, as they were hunting about on the ground for Tabeau's tracks, something that looked like a little puddle of blood, but which the darkness prevented them from verifying. With these details they returned to our camp, and their report saddened all our hearts.

10th.--This morning, as soon as there was light enough to follow tracks, I set out myself, with Mr. Fitzpatrick and several men, in search of Tabeau. We went to the spot where the appearance of puddled blood had been seen; and this, we saw at once, had been the place where he fell and died. Blood upon the leaves, and beaten-down bushes, showed that he had got his wound about twenty paces from where he fell, and that he had struggled for his life. He had probably been shot through the lungs with an arrow. From the place where he lay and bled, it could be seen that he had been dragged to the river bank, and thrown into it. No vestige of what had belonged to him could be found, except a fragment of his horse equipment. Horse, gun, clothes--all became the prey of these Arabs of the New World.

Tabeau had been one of our best men, and his unhappy death spread a gloom over our party. Men, who have gone through such dangers and sufferings as we had seen, become like brothers, and feel each other's loss. To defend and avenge each other, is the deep feeling of all. We wished to avenge his death; but the condition of our horses, languishing for grass and repose, forbade an expedition into unknown mountains. We knew the tribe who had done the mischief--the same which had been insulting our camp. They knew what they deserved, and had the discretion to show themselves to us no more. The day before, they infested our camp; now, not one appeared; nor did we ever afterwards see but one who even belonged to the same tribe, and he at a distance.

Our camp was in a basin below a deep canon--a gap of two thousand feet deep in the mountain--through which the Rio Virgen passes, and where no man or beast could follow it. The Spanish trail, which we had lost in the sands of the basin, was on the opposite side of the river. We crossed over to it, and followed it northwardly towards a gap which was visible in the mountain. We approached it by a defile, rendered difficult for our barefooted animals by the rocks strewed along it; and here the country changed its character. From the time we entered the desert, the mountains had been bald and rocky; here they began to be wooded with cedar and pine, and clusters of trees gave shelter to birds--a new and welcome sight--which could not have lived in the desert we had passed.

Descending a long hollow, towards the narrow valley of a stream, we saw before us a snowy mountain, far beyond which appeared another more lofty still. Good bunch-grass began to appear on the hill-sides, and here we found a singular variety of interesting shrubs. The changed appearance of the country infused among our people a more lively spirit, which was heightened by finding at evening a halting-place of very good grass on the clear waters of the Santa Clara fork of the Rio Virgen.

11th.--The morning was cloudy and quite cool, with a shower of rain--the first we have had since entering the desert, a period of 27 days--and we seem to have entered a different climate, with the usual weather of the Rocky mountains. Our march to-day was very laborious, over very broken ground, along the Santa Clara river; but then the country is no longer so distressingly desolate. The stream is prettily wooded with sweet cottonwood trees--some of them of large size; and on the hills, where the nut-pine is often seen, a good and wholesome grass occurs frequently. This cottonwood, which is now in fruit, is of a different species from any in Michaux's Sylva. Heavy dark clouds covered the sky in the evening and a cold wind sprang up, making fires and overcoats comfortable.

12th.--A little above our encampment the river forked, and we continued up the right-hand branch, gradually ascending towards the summit of the mountain. As we rose towards the head of the creek, the snowy mountains on our right showed out handsomely--high and rugged, with precipices, and covered with snow for about two thousand feet from their summits down. Our animals were somewhat repaid for their hard marches by an excellent camping-ground on the summit of the ridge, which forms here the dividing chain between the waters of the Rio Virgen, which goes south to the Colorado, and those of Sevier river, flowing northwardly, and belonging to the Great Basin. We considered ourselves as crossing the rim of the basin; and, entering it at this point, we found here an extensive mountain meadow, rich in bunch-grass, and fresh with numerous springs of clear water, all refreshing and delightful to look upon. It was, in fact, that las Vegas de Santa Clara, which had been so long presented to us as the terminating point of the desert, and where the annual caravan from California to New Mexico halted and recruited for some weeks. It was a very suitable place to recover from the fatigue and exhaustion of a month's suffering in the hot and sterile desert. The meadow was about a mile wide, some ten miles long, bordered by grassy hills and mountains-- some of the latter rising two thousand feet, and white with snow down to the level of the vegas. Its elevation above the sea was 5,280 feet; latitude, by observation, 37° 28' 28", and its distance from where we first struck the Spanish trail about 400 miles. Counting from the time we reached the desert, and began to skirt, at our descent from Walker's Pass in the Sierra Nevada, we had traveled 550 miles, occupying 27 days, in that inhospitable region. In passing before the Great Caravan, we had the advantage of finding more grass, but the disadvantage of finding also the marauding savages, who had gathered down upon the trail, waiting the approach of that prey. This greatly increased our labors, besides costing us the life of an excellent man. We had to move all day in a state of watch, and prepared for combat--scouts and flankers out, a front and rear division of our men, and baggage-animals in the centre. At night, camp duty was severe. Those who had toiled all day, had to guard, by turns, the camp and the horses, all night. Frequently one-third of the whole party were on guard at once; and nothing but this vigilance saved us from attack. We were constantly dogged by bands, and even whole tribes of marauders; and although Tabeau was killed, and our camp infested and insulted by some, while swarms of them remained on the hills and mountain- sides, there was manifestly a consultation and calculation going on, to decide the question of attacking us. Having reached the resting-place of the Vegas de Santa Clara, we had complete relief from the heat and privations of the desert, and some relaxation from the severity of camp duty. Some relaxation, and relaxation only--for camp-guards, horse-guards, and scouts, are indispensable from the time of leaving the frontiers of Missouri until we return to them.

After we left the Vegas, we had the gratification to be joined by the famous hunter and trapper, Mr. Joseph Walker, whom I have before mentioned, and who now became our guide. He had left California with the great caravan; and perceiving, from the signs along the trail, that there was a party of whites ahead, which he judged to be mine, he detached himself from the caravan, with eight men, (Americans,) and ran the gauntlet of the desert robbers, killing two, and getting some of the horses wounded, and succeeded in overtaking us. Nothing but his great knowledge of the country, great courage and presence of mind, and good rifles, could have brought him safe from such a perilous enterprise.

13th.--We remained one day at this noted place of rest and refreshment; and, resuming our progress in a northwestwardly direction, we descended into a broad valley, the water of which is tributary to Sevier lake. The next day we came in sight of the Wahsatch range of mountains on the right, white with snow, and here forming the southeast part of the Great Basin. Sevier lake, upon the waters of which we now were, belonged to the system of lakes in the eastern part of the Basin --of which, the Great Salt lake, and its southern limb, the Utah lake, were the principal--towards the region of which we were now approaching. We traveled for several days in this direction, within the rim of the Great Basin, crossing little streams which bore to the left for Sevier lake; and plainly seeing, by the changed aspect of the country, that we were entirely clear of the desert, and approaching the regions which appertained to the system of the Rocky mountains. We met, in this traverse, a few mounted Utah Indians, in advance of their main body, watching the approach of the great caravan.

16th.--We reached a small salt lake, about seven miles long and one broad, at the northern extremity of which we encamped for the night. This little lake, which well merits its characteristic name, lies immediately at the base of the Wah-satch range, and nearly opposite a gap in that chain of mountains through which the Spanish trail passes; and which, again falling upon the waters of the Colorado, and crossing that river, proceeds over a mountainous country to Santa Fé.

17th.--After 440 miles of traveling on a trail, which served for a road, we again found ourselves under the necessity of exploring a track through the wilderness. The Spanish trail had borne off to the southeast, crossing the Wah-satch range. Our course led to the northeast, along the foot of that range, and leaving it on the right. The mountain presented itself to us under the form of several ridges, rising one above the other, rocky, and wooded with pine and cedar; the last ridge covered with snow. Sevier river, flowing northwardly to the lake of the same name, collects its principal waters from this section of the Wah-satch chain. We had now entered a region of great pastoral promise, abounding with fine streams, the rich bunch-grass, soil that would produce wheat, and indigenous flax growing as if it had been sown. Consistent with the general character of its bordering mountains, this fertility of soil and vegetation does not extend far into the Great Basin. Mr. Joseph Walker, our guide, and who has more knowledge of these parts than any man I know, informed me that all the country to the left was unknown to him, and that even the Digger tribes, which frequented Lake Sevier, could tell him nothing about it.

20th.--We met a band of Utah Indians, headed by a well-known chief, who had obtained the American or English name of Walker, by which he is quoted and well known. They were all mounted, armed with rifles, and used their rifles well. The chief had a fusee, which he carried slung, in addition to his rifle. They were journeying slowly towards the Spanish trail, to levy their usual tribute upon the great California caravan. They were robbers of a higher order than those of the desert. They conducted their depredations with form, and under the color of trade and toll, for passing through their country. Instead of attacking and killing, they affect to purchase--taking the horses they like, and giving something nominal in return. The chief was quite civil to me. He was personally acquainted with his namesake, our guide, who made my name known to him. He knew of my expedition of 1842; and, as tokens of friendship, and proof that we had met, proposed an interchange of presents. We had no great store to choose out of; so he gave me a Mexican blanket, and I gave him a very fine one which I had obtained at Vancouver.

23d.--We reached Sevier river--the main tributary of the lake of the same name--which, deflecting from its northern course, here breaks from the mountains to enter the lake. It was really a fine river, from eight to twelve feet deep; and after searching in vain for a fordable place, we made little boats (or rather rafts) out of bulrushes, and ferried across. These rafts are readily made, and give a good conveyance across a river. The rushes are bound in bundles, and tied hard; the bundles are tied down upon poles, as close as they can be pressed, and fashioned like a boat, in being broader in the middle and pointed at the ends. The rushes, being tubular and jointed, are light and strong. The raft swims well, and is shoved along by poles, or paddled, or pushed and pulled by swimmers, or drawn by ropes. On this occasion, we used ropes--one at each end--and rapidly drew our little float backwards and forwards from shore to shore. The horses swam. At our place of crossing, which was the most northern point of its bend, the latitude was 39° 22' 19". The banks sustained the character for fertility and vegetation which we had seen for some days. The name of this river and lake was an indication of our approach to regions of which our people had been the explorers. It was probably named after some American trapper or hunter, and was the first American name we had met with since leaving the Columbia river. From the Dalles to the point where we turned across the Sierra Nevada, near 1,000 miles, we heard Indian names, and the greater part of the distance none; from Nueva Helvetia (Sacramento) to las Vegas de Santa Clara, about 1,000 more, all were Spanish; from the Mississippi to the Pacific, French and American or English were intermixed; and this prevalence of names indicates the national character of the first explorers.

We had here the misfortune to lose one of our people, François Badeau, who had been with me on both expeditions; during which he had always been one of my most faithful and efficient men. He was killed in drawing towards him a gun by the muzzle; the hammer being caught, discharged the gun, driving the ball through his head. We buried him on the banks of the river.

Crossing the next day a slight ridge along the river, we entered a handsome mountain valley covered with fine grass, and directed our course towards a high snowy peak, at the foot of which lay the Utah lake. On our right was a bed of high mountains, their summits covered with snow, constituting the dividing ridge between the Basin waters and those of the Colorado. At noon we fell in with a party of Utah Indians coming out of the mountain, and in the afternoon encamped on a tributary to the lake, which is separated from the waters of the Sevier by very slight dividing grounds.

Early the next day we came in sight of the lake; and, as we descended to the broad bottoms of the Spanish fork, three horsemen were seen galloping towards us, who proved to be Utah Indians--scouts from a village, which was encamped near the mouth of the river. They were armed with rifles, and their horses were in good condition. We encamped near them, on the Spanish fork, which is one of the principal tributaries to the lake. Finding the Indians troublesome, and desirous to remain here a day, we removed the next morning farther down the lake and encamped on a fertile bottom near the foot of the same mountainous ridge which borders the Great Salt lake, and along which we had journeyed the previous September. Here the principal plants in bloom were two, which were remarkable as affording to the Snake Indians--the one an abundant supply of food, and the other the most useful among the applications which they use for wounds. These were the kooyah plant, growing in fields of extraordinary luxuriance, and convollaria stellata, which, from the experience of Mr. Walker, is the best remedial plant known among these Indians. A few miles below us was another village of Indians, from which we obtained some fish--among them a few salmon trout, which were very much inferior in size to those along the Californian mountains. The season for taking them had not yet arrived; but the Indians were daily expecting them to come up out of the lake.

We had now accomplished an object we had in view when leaving the Dalles of the Columbia in November last: we had reached the Utah lake; but by a route very different from the one we had intended, and without sufficient time remaining to make the examinations which we desired. It is a lake of note in this country, under the dominion of the Utahs, who resort to it for fish. Its greatest breadth is about fifteen miles, stretching far to the north, narrowing as it goes, and connecting with the Great Salt lake. This is the report, which I believe to be correct; but it is fresh water, while the other is not only salt, but a saturated solution of salt; and here is a problem which requires to be solved. It is almost entirely surrounded by mountains, walled on the north and east by a high and snowy range, which supplies to it a fan of tributary streams. Among these, the principal river is the Timpan-ogo--signifying Rock river--a name which the rocky grandeur of its scenery, remarkable even in this country of rugged mountains, has obtained for it from the Indians. In the Utah language, og-wah-be, the term for river, when coupled with other words in common conversation, is usually abbreviated to ogo; timpan signifying rock. It is probable that this river furnished the name which on the older maps has been generally applied to the Great Salt lake; but for this I have preferred a name which will be regarded as highly characteristic, restricting to the river the descriptive term Timpan-ogo, and leaving for the lake into which it flows the name of the people who reside on its shores, and by which it is known throughout the country.

The volume of water afforded by the Timpan-ogo is probably equal to that of the Sevier river; and, at the time of our visit, there was only one place in the lake-valley at which the Spanish fork was fordable. In the cove of the mountains along its eastern shore, the lake is bordered by a plain, where the soil is generally good, and in greater part fertile; watered by a delta of prettily timbered streams. This would be an excellent locality for stock-farms; it is generally covered with good bunch-grass, and would abundantly produce the ordinary grains.

In arriving at the Utah lake, we had completed an immense circuit of twelve degrees diameter north and south, and ten degrees east and west; and found ourselves, in May, 1844, on the same sheet of water which we had left in September, 1843. The Utah is the southern limb of the Great Salt lake; and thus we had seen that remarkable sheet of water both at its northern and southern extremity, and were able to fix its position at these two points. The circuit which we had made, and which had cost us eight months of time, and 3,500 miles of traveling, had given us a view of Oregon and of North California from the Rocky mountains to the Pacific ocean, and of the two principal streams which form bays or harbors on the coast of that sea. Having completed this circuit, and being now about to turn the back upon the Pacific slope of our continent, and to recross the Rocky mountains, it is natural to look back upon our footsteps, and take some brief view of the leading features and general structure of the country we had traversed. These are peculiar and striking, and differ essentially from the Atlantic side of the country. The mountains all are higher, more numerous, and more distinctly defined in their ranges and directions; and, what is so contrary to the natural order of formations, one of these ranges, which is near the coast, (the Sierra Nevada and the Coast Range,) presents higher elevations and peaks than any which are to be found in the Rocky mountains themselves. In our eight months' circuit, we were never out of sight of snow; and the Sierra Nevada, where we crossed it, was near 2,000 feet higher than the South Pass in the Rocky mountains. In height, these mountains greatly exceed those of the Atlantic side, constantly presenting peaks which enter the region of eternal snow; and some of them volcanic, and in a frequent state of activity. They are seen at great distances, and guide the traveler in his course.

The course and elevation of these ranges give direction to the rivers and character to the coast. No great river does, or can, take its rise below the Cascade and Sierra Nevada range; the distance to the sea is too short to admit of it. The rivers of the San Francisco bay, which are the largest after the Columbia, are local to that bay, and lateral to the coast, having their sources about on a line with the Dalles of the Columbia, and running each in a valley of its own, between the Coast range and the Cascade and Sierra Nevada range. The Columbia is the only river which traverses the whole breadth of the country, breaking through all the ranges, and entering the sea. Drawing its waters from a section of ten degrees of latitude in the Rocky mountains, which are collected into one stream by three main forks (Lewis's, Clark's, and the North fork) near the centre of the Oregon valley, this great river thence proceeds by a single channel to the sea, while its three forks lead each to a pass in the mountains, which opens the way into the interior of the continent. This fact in relation to the rivers of this region, gives an immense value to the Columbia. Its mouth is the only inlet and outlet to and from the sea: its three forks lead to the passes in the mountains: it is, therefore, the only line of communication between the Pacific and the interior of North America; and all operations of war or commerce, of national or social intercourse, must be conducted upon it. This gives it a value beyond estimation, and would involve irreparable injury if lost. In this unity and concentration of its waters, the Pacific side of our continent differs entirely from the Atlantic side, where the waters of the Alleghany mountains are dispersed into many rivers, having their different entrances into the sea, and opening many lines of communication with the interior.

The Pacific coast is equally different from that of the Atlantic. The coast of the Atlantic is low and open, indented with numerous bays, sounds, and river estuaries, accessible everywhere, and opening by many channels into the heart of the country. The Pacific coast, on the contrary, is high and compact, with few bays, and but one that opens into the heart of the country. The immediate coast is what the seamen call iron-bound. A little within, it is skirted by two successive ranges of mountains, standing as ramparts between the sea and the interior of the country; and to get through which there is but one gate, and that narrow and easily defended. This structure of the coast, backed by these two ranges of mountains, with its concentration and unity of waters, gives to the country an immense military strength, and will probably render Oregon the most impregnable country in the world.

Differing so much from the Atlantic side of our continent, in coast, mountains, and rivers, the Pacific side differs from it in another most rare and singular feature--that of the Great Interior Basin, of which I have so often spoken, and the whole form and character of which I was so anxious to ascertain. Its existence is vouched for by such of the American traders and hunters as have some knowledge of that region; the structure of the Sierra Nevada range of mountains requires it to be there; and my own observations confirm it. Mr. Joseph Walker, who is so well acquainted in these parts, informed me that, from the Great Salt lake west, there was a succession of lakes and rivers which have no outlet to the sea, nor any connection with the Columbia, or with the Colorado of the Gulf of California. He described some of these lakes as being large, with numerous streams, and even considerable rivers falling into them. In fact, all concur in the general report of these interior rivers and lakes; and, for want of understanding the force and power of evaporation, which so soon establishes an equilibrium between the loss and supply of waters, the fable of whirlpools and subterraneous outlets has gained belief, as the only imaginable way of carrying off the waters which have no visible discharge. The structure of the country would require this formation of interior lakes; for the waters which would collect between the Rocky mountains and the Sierra Nevada, not being able to cross this formidable barrier, nor to get to the Columbia or the Colorado, must naturally collect into reservoirs, each of which would have its little system of streams and rivers to supply it. This would be the natural effect; and what I saw went to confirm it. The Great Salt lake is a formation of this kind, and quite a large one; and having many streams, and one considerable river, 400 or 500 miles long, falling into it. This lake and river I saw and examined myself; and also saw the Wah-satch and Bear River mountains, which enclose the waters of the lake on the east, and constitute, in that quarter, the rim of the Great Basin. Afterwards, along the eastern base of the Sierra Nevada, where we traveled for 42 days, I saw the line of lakes and rivers which lie at the foot of that Sierra; and which Sierra is the western rim of the Basin. In going down Lewis's fork and the main Columbia, I crossed only inferior streams coming in from the left, such as could draw their water from a short distance only; and I often saw the mountains at their heads white with snow,--which, all accounts said, divided the waters of the desert from those of the Columbia, and which could be no other than the range of mountains which form the rim of the Basin on its northern side. And in returning from California along the Spanish trail, as far as the head of the Santa Clara fork of the Rio Virgen, I crossed only small streams making their way south to the Colorado, or lost in sand, (as the Mo-hah-ve;) while to the left, lofty mountains, their summits white with snow, were often visible, and which must have turned water to the north as well as to the south, and thus constituted, on this part, the southern rim of the Basin. At the head of the Santa Clara fork, and in the Vegas de Santa Clara, we crossed the ridge which parted the two systems of waters. We entered the Basin at that point, and have traveled in it ever since; having its southeastern rim (the Wah-satch mountain) on the right, and crossing the streams which flow down into it. The existence of the Basin is, therefore, an established fact in my mind: its extent and contents are yet to be better ascertained. It cannot be less than 400 or 500 miles each way, and must lie principally in the Alta California; the demarcation latitude of 42° probably cutting a segment from the north part of the rim. Of its interior, but little is known. It is called a desert, and, from what I saw of it, sterility may be its prominent characteristic; but where there is so much water, there must be some oasis. The great river, and the great lake, reported, may not be equal to the report; but where there is so much snow, there must be streams; and where there is no outlet, there must be lakes to hold the accumulated waters, or sands to swallow them up. In this eastern part of the Basin, containing Sevier, Utah, and the Great Salt lakes, and the rivers and creeks falling into them, we know there is good soil and good grass, adapted to civilized settlements. In the western part, on Salmon Trout river, and some other streams, the same remark may be made.

The contents of this great Basin are yet to be examined. That it is peopled, we know; but miserably and sparsely. From all that I heard and saw, I should say that humanity here appeared in its lowest form, and in its most elementary state. Dispersed in single families; without fire- arms; eating seeds and insects; digging roots, (and hence their name,)-- such is the condition of the greater part. Others are a degree higher, and live in communities upon some lake or river that supplies fish, and from which they repulse the miserable Digger. The rabbit is the largest animal known in this desert; its flesh affords a little meat; and their bag-like covering is made of its skins. The wild sage is their only wood, and here it is of extraordinary size--sometimes a foot in diameter, and six or eight feet high. It serves for fuel, for building material, for shelter to the rabbits, and for some sort of covering for the feet and legs in cold weather. Such are the accounts of the inhabitants and productions of the Great Basin; and which, though imperfect, must have some foundation, and excite our desire to know the whole.

The whole idea of such a desert, and such a people, is a novelty in our country, and excites Asiatic, not American ideas. Interior basins, with their own systems of lakes and rivers, and often sterile, are common enough in Asia; people still in the elementary state of families, living in deserts, with no other occupation than the mere animal search for food, may still be seen in that ancient quarter of the globe; but in America such things are new and strange, unknown and unsuspected, and discredited when related. But I flatter myself that what is discovered, though not enough to satisfy curiosity, is sufficient to excite it, and that subsequent explorations will complete what has been commenced.

This account of the Great Basin, it will be remembered, belongs to the Alta California, and has no application to Oregon, whose capabilities may justify a separate remark. Referring to my journal for particular descriptions, and for sectional boundaries between good and bad districts, I can only say, in general and comparative terms, that, in that branch of agriculture which implies the cultivation of grains and staple crops, it would be inferior to the Atlantic States, though many parts are superior for wheat; while in the rearing of flocks and herds it would claim a high place. Its grazing capabilities are great; and even in the indigenous grass now there, an element of individual and national wealth may be found. In fact, the valuable grasses begin within one hundred and fifty miles of the Missouri frontier, and extend to the Pacific ocean. East of the Rocky mountains, it is the short curly grass, on which the buffalo delights to feed, (whence its name of buffalo,) and which is still good when dry and apparently dead. West of those mountains it is a larger growth, in clusters, and hence called bunch-grass, and which has a second or fall growth. Plains and mountains both exhibit them; and I have seen good pasturage at an elevation of ten thousand feet. In this spontaneous product the trading or traveling caravans can find subsistence for their animals; and in military operations any number of cavalry may be moved, and any number of cattle may be driven; and thus men and horses be supported on long expeditions, and even in winter, in the sheltered situations.

Commercially, the value of the Oregon country must be great, washed as it is by the North Pacific ocean--fronting Asia--producing many of the elements of commerce--mild and healthy in its climate--and becoming, as it naturally will, a thoroughfare for the East India and China trade.

Turning our faces once more eastward, on the morning of the 27th we left the Utah lake, and continued for two days to ascend the Spanish fork, which is dispersed in numerous branches among very rugged mountains, which afford few passes, and render a familiar acquaintance with them necessary to the traveler. The stream can scarcely be said to have a valley, the mountains rising often abruptly from the water's edge; but a good trail facilitated our traveling, and there were frequent bottoms, covered with excellent grass. The streams are prettily and variously wooded; and everywhere the mountain shows grass and timber.

At our encampment on the evening of the 28th, near the head of one of the branches we had ascended, strata of bituminous limestone were displayed in an escarpment on the river bluffs, in which were contained a variety of fossil shells of new species.

It will be remembered, that in crossing this ridge about 120 miles to the northward in August last, strata of fossiliferous rock were discovered, which have been referred to the oolitic period; it is probable that these rocks also belong to the same formation.
