"Hold one up to the light and tell me what you notice about it.""Oh, I know," said Norah. "You mean the veins. These are net-veined leaves. The veins branch out and spread through the leaf in all directions.""Quite right, Norah," said Fred, "and now I want you to examine some other seeds for yourself. Here are some large seeds such as apple-seeds and pear- seeds, plum and cherry stones, almonds, acorns, and peas. Here, too, I have some small ones-radish seeds and mustard seeds. If you open them you will find that every one of them has double seed-leaves.
"Now take them one by one and think what
kind of leaves they produce when they grow up into plants. The apple tree and the pear tree, the plum and cherry trees, the almond tree and the oak all have the same net-veined leaves. So have peas, radishes, and the mustard plant.
