About stems, however, even I felt a little discouraged; for though it is from the stem that all other parts of a plant grow, yet it is not looked upon generally as an interesting object when studied by itself; and I dare say you children still feel that stems are less amusing than fruits, or seeds, or roots.

Still we can hardly help admiring the way in which a stem, when it lies underground, like that of the lily or the Jack-in-the-pulpit, makes its food so carefully all through the summer, and waits so patiently through the long winter in order to help its plant to burst into flower, and to ripen into fruit as soon as possible, and without more labor and food hunting when the spring comes.

When a stem, like that of the morning-glory, sweeps slowly and carefully through the air in search of something to lay hold of in its efforts to climb upward, and when, on finding this support, it makes such good use of it, we feel inclined to say, “Well done, little stem.”

And when a stem on land knows how to keep off meddlers, yet has the wisdom not to take unnecessary trouble when afloat, like that of the amphibious knotweed, then we feel that a plant gives its stem, as well as its other parts, a large supply of common sense.

There is a great deal more that might be said on this subject. What a plant lives on, what it eats and drinks and breathes, is very interesting to learn about. And of course the food taken in by the roots must be carried upward through the stem. But to write simply about this is difficult. As much as I think most of you can understand, I will tell you when we take up leaves.

Part IV—Buds

BUDS IN WINTER

When school opened in September, all the trees were covered with leaves; and some of these trees were bent with their burden of pears and apples and peaches, while others were hung with prickly chestnut burrs or with acorns or walnuts.

But now all is changed. The woods look gray and bare; for nearly all the leaves have fallen save those of the oak, which are still holding fast to the branches. These oak leaves are brown and stiff and leathery. They crackle and rustle when the wind blows through them.
