Which of the two boys gave the better tillage to the soil? During the summer you will see how others care for their plants and you will see instances of good tillage and poor tillage. You must observe and write me which of the two had the better success in having the seed come up. The difference between the two ways does not end in sowing and germination of seed, but continues all summer until the end of the season. Billy Boy will care for the soil by combing it with a rake several times a week, with the same care and affection with which the lover of a horse will groom the animal each morning. The chum will think the plants are all like goats, and ought to live with almost any chance. Billy Boy will have no weeds among his plants and his chum will have them in great numbers. The chum may say that weeds shade the plants and thereby protect them from drought. I have known grown-up farmers to say that. Is it true? Go on a voyage of discovery and find out. I hope your garden may be of the Billy Boy kind, receiving plenty of tillage. You will have no trouble to find any number of the other kind of gardens growing to weeds and receiving no tillage. It will please me very much if you will write me, giving as many reasons as you can why tillage makes the soil more fertile (or "rich") and able to produce better plants and flowers. Each letter will be carefully read. AN EXPERIMENT. Perhaps you can answer the questions by watching your garden or some one's else garden; but you can answer them better if you will grow a few "hills" of corn. In the fall I shall have many questions to ask you about corn, and I want you to be able to answer by telling me what you have seen with your own eyes. Those of you who are Junior Naturalists have done well with your dues this year, but we must always do better next year than we did last; so I want you to know many things about Indian corn when you come back to school in the fall. Your teacher has also been asked to study corn, and I am going to study it myself. I am a farmer and I have grown corn all my life. Once I thought that I knew all about it; but frequently some one asks me a question about it that I cannot answer.
