Lesson CXCIV
The Chestnut
Leading thought—The chestnut is one of our most beautiful trees. We should learn to appreciate it by observing the beauty of its blossoms and of its foliage when green and when brilliant yellow in autumn. Until the chestnut fruit is ripe, it is well protected by its spiny bur.
Method—This study may be begun in the fall when chestnuts are ripe. Ask the boys to describe the trees from which they get this longed-for harvest. The leaves, burs and nuts may be studied in the schoolroom.
Observations—1. Where do chestnut trees grow? What is the general form of the head of the tree? How high is the trunk below the branches? Do the branches divide into fine twigs or spray at the tips?
2. Sketch and describe a chestnut leaf, showing the veins, edges and petiole. Are the leaves placed opposite or alternate? What is their color above and below? How do the chestnut leaves differ from those of the beech and of the chestnut oak? What is the color of the chestnut foliage in autumn?
3. Where on the branch is the bur borne? How does the green chestnut bur look? Why is this prickly exterior beneficial to the fruit? Does the bur open easily when green? What causes the chestnut bur to open? Into how many lobes does it open? Describe an open bur outside and in.
4. Where in the bur are the chestnuts set? How many in one bur? How can you tell by the shape of the chestnut whether it grew as a twin or single in a bur? Are there ever three in a bur? If so, what shape is the middle one? Do the burs fall when the chestnuts are ripe?
5. Take a single chestnut. Describe its shape and color. What is the mark on its large end? Describe the coloring and covering of the tip. Open the shell and note the lining. Describe how the meat is finally protected. Can you see where the germ is? Plant a chestnut and watch it grow.
6. Study the chestnut blossom in late June or July. What kind of blossoms are those which look like yellow stars all over the tree? Study one of the catkins which makes a ray of the star, and describe it. Can you see the anthers and the pollen? How many of these pollen-bearing flowers are on one stem? Where are the pistillate flowers which will grow into young chestnuts? Describe them.
7. How much are chestnuts worth per bushel? To what uses is chestnut timber put? What is the character of the wood?
