"Tom," said I to a young friend who stood by the window tossing a ten-cent piece into the air, "what plant is used for part of the design on that coin?" The boy did not answer right away. I do not believe he had ever looked at it closely; yet this is one of the prettiest of our silver pieces. After a few minutes he said, "It is corn, isn't it?" Hearing a note of surprise in his voice, I told him something about corn-raising in this country. We then decided that it is a good thing to represent corn on one of the United States coins, since it is a source of much of our wealth. But aside from its value, Indian corn should interest us because it is a wonderful plant. Boys and girls do not know much more about it than does any old black crow. You have watched the farmer plant corn and you like to eat it. Jim Crow has watched the farmer plant corn and he likes to eat it, too. The time has come, however, when you can get ahead of him if you care to; and to get ahead of crows on the corn question is worth the while. Let me tell you how to do it. 1. Secure a kernel of corn, cut it in halves, and note the food inside it. This food was stored in the seed by the parent plant. Uncle John would say that it is the "lunch" that the mother puts up for her children. What must happen before the food can be used by the little plant? 2. Place some moist soil in a tumbler, and put a kernel of corn in it near the side so that you can watch it grow. How soon does the root appear? The leaves? How many leaves come up at one time? 3. Ask your father to give you a small piece of ground in the garden. Plant a few kernels of corn so that you will have some plants of your own to study this summer. Other people's plants are never so interesting as our own. 4. As your corn plants push their way up into the light and air, watch them every day. Notice how the new leaves are protected by the next older ones. 5. Is the stem hollow or solid? In which way would it be stronger? 6. Notice the joints. Are they the same distance apart throughout the length of the stem? Does the distance between the joints always remain the same? Measure them some day; then in a week measure them again. 7. Where does the stalk break most easily? 8. Where does the leaf clasp the stalk? 9. Notice how strong the leaf is. In what direction do the ribs extend? If these long narrow leaves were not strong what would happen to them as they wave back and forth in the wind? 10. Have you ever noticed the ruffled edges of the leaves? As you bend them you will see that the edges do not tear. 11. There are two kinds of blossoms on a corn plant. The ear bears one kind, the tassel the other. If you were to cut all the tassels from the plants in your garden, the kernels would not grow on the ears. Later on you will learn why. 12. Watch the ear closely as it grows. 13. Follow a thread of silk to the place where it is attached. Notice whether there is one silk for each kernel.
