Fig. 130

Here you see a branch from the red maple (Fig. [130]).

On the flowering shoots three buds grow side by side. The middle, smaller one holds the leaves. These leaves do not appear until the two outer, larger buds have burst into flower clusters; for the flowers of the red maple appear before its leaves.

I want you to bring to school as many different kinds of branches as you can find, and I hope you will examine them all very carefully. Notice the position of their buds, and whether these grow close together or are scattered far apart, and whether one bud grows just opposite another; and look for the marks left by the leaves which broke off last fall.

When the buds are large enough, you will find it interesting to pull them apart (but you must do this with great care) and see how beautifully wrapped are the baby leaves and flowers.

I chose the branch of the horse-chestnut for special examination, because its large buds show their contents plainly.

When a bud grows on the tip of a stem, its work is to carry on that stem; but when it grows just above a leaf scar, you can be sure that it is a young branch. Such a branch may bear either leaves or flowers, or both.

But buds do not all grow up at the same time, or necessarily at all.

The strongest ones are the first to open. The others may keep quiet for some time, not unfolding, perhaps, unless some of the earlier ones are killed. In this case, the waiting buds try to fill the gap, and carry on the good work of clothing the tree with leaves and flowers.

Sometimes they wait over till another year, and occasionally a bud never opens at all.
