Lesson LIV

The Muskrat

Leading thought—The muskrat, while a true rodent, is fitted for life in the water more than for life upon the land. Its hind feet are webbed for use as oars and its tail is used as a rudder. It builds lodges of mud, cat-tails and rushes in which it spends the winter.

Method—It might be well to begin this work by asking for observations on the tracks of the muskrat which may be found about the edges of almost any creek, pond or marsh. If there are muskrat lodges in the region they should be visited and described. For studying the muskrat’s form a live muskrat in captivity is almost necessary. If one is trapped with a “figure four” it will not be injured and it may be made more or less tame by feeding it with sweet apples, carrots and parsnips. The pupils can thus study it at leisure although they should not be allowed to handle the creature as it inflicts very severe wounds and is never willing to be handled. If a live muskrat cannot be obtained perhaps some hunter in the neighborhood will supply a dead one for this observation lesson.

While studying the muskrat the children should read all the stories of beavers which are available as the two animals are very much alike in their habits.

Observations—1. In what locality have you discovered the tracks of the muskrat? Describe its general appearance. Measure the muskrat’s track as follows: (a) Width and length of the print of one foot; (b) the width between the prints of the two hind feet; (c) the length between the prints made by the hind feet in several successive steps or jumps.

2. Was the muskrat’s track made when the animal was jumping or walking? Can you see in it a difference in the size of the front and hind feet? Judging from the track, where do you think the muskrat came from? What do you think it was hunting for?

3. What mark does the tail make in the snow or mud? Judging by its imprint, should you think the muskrat’s tail was long or short, bare or brushy, slender or strong?

4. How long is the largest muskrat you ever saw? How much of the whole length is tail? Is the general shape of the body short and heavy or long and slender?

5. Describe the muskrat’s eyes, ears and teeth. For what are the teeth especially fitted? Has the muskrat whiskers like mice and rats?

6. Compare the front and hind legs as to size and shape. Is there a web between the toes of the hind feet? What does this indicate? Do you think that the muskrat is a good swimmer?

7. Describe the muskrat fur. Compare the outer and under coat. What is its color above and below? What is the name of muskrat fur in the shops?

8. Describe the tail. What is its covering? How is it flattened? What do you think this strong, flattened tail is used for?

9. Do you think the muskrat is better fitted to live in the water than on land? How is it fitted to live in the water in the following particulars: Feet? Tail? Fur?

10. How much of the muskrat can you see when it is swimming? How long can it stay under water when diving?

11. What is the food of the muskrat? Where does it find it? How does it prepare the food for eating? Does it seek its food during the night or day? Have you ever observed the muskrat’s dining room? If so, describe it.

12. Describe the structure of the muskrat’s winter lodge, or cabin, in the following particulars: Its size. Where built? Of what material? How many rooms in it? Are these rooms above or below the water level? Of what is the bed made? How is the nest ventilated? How is it arranged so that the entrance is not closed by the ice? Is such a home built by one or more muskrats? How many live within it? Do the muskrats always build these winter cabins? What is the character of the shores where they are built?

13. Describe the muskrat’s burrow in the bank in the following particulars: Is the entrance above or below water? Where and how is the nest made? Is it ventilated? Does it have a back door leading out upon the land?

14. What are the muskrat’s enemies? How does it escape them? How does it fight? Is it a courageous animal? How does the muskrat give warning to its fellows when it perceives danger? At what time of year is it comparatively safe? At what time is it exposed to greatest danger?

15. Why is this animal called muskrat? Compare the habits of muskrats with those of beaver and write an English theme upon the similarity of the two.

16. At what time of year do you find the young muskrats? How many in a litter?

17. Read Farmers’ Bulletin No. 396 of the U. S. Dept. of Agriculture and write an English theme on the destructive habits of muskrats and the economic uses of these animals.
