To get results we must first learn and then teach what we know. The finest game in the world is to teach. No one ever knows anything thoroughly till he tries to teach it.
When you tell a person how to do a thing, he doesn't know how to do it himself. When you show him how to do it, still he doesn't know that he could do it himself. But when you get him to do it himself, then he knows.
Country boys will believe that early tomatoes can be raised by starting them in the house; but like the rest of us they don't know how to do it, and when spring comes and it is time to do such things, they are busy on the farm. There are several schools trying the experience of allowing the children to plant in window boxes in early April and are showing them how to do it. But as there is not room for all the children to plant in these window boxes, there is a new idea which originated in the country, where the children are engaged in the fall and the spring assisting their parents at agricultural work.
It was hard to get up any interest in school gardens, but it was all the more important that they should have agricultural instruction in the winter time.
At Berkeley Heights, N. J., we devised this simple plan, and it works. We made a number of wooden boxes, one foot wide, two feet long, so they will just fit on the ledge of a school desk. They are only three inches deep, with a bottom of tin, turned up at the edges, or of well painted pine, white-leaded at the joints. There is no drainage, since we discovered that if they are not watered too much, they do better without drainage. The holes usually made in the bottoms of flower boxes carry off a lot of plant food with the water that runs through.
Now, how to store these boxes when they are not in the sunny places near the windows? Why, we set up four posts of one-inch stuff at the four corners, so that the box looks like a kitchen table turned upside down (see illustration). Now the boxes filled with earth and with the young plants growing can be stored at night, one on top of the other, by the wall of the schoolroom.
If it is going to be cold, and over Sundays, the pile of them can be covered with newspapers, which keep them from getting chilled and from drying up, or the boxes can be covered and carried home by the children. We found that for most plants nine inches is high enough for the posts, and that well-seasoned one-inch lumber is heavy enough not to warp if it is painted inside and out, and it is not too heavy to lift.
By the way, better paint the joints before the sides are nailed together. It makes them more water-tight. Four screws at the corners will make them still tighter.
The scholars raise lettuce, parsley, onions, and strawberries, and all kinds of small plants, as well as flowers, in the winter; and when the plants get too big or two crowded for the boxes, they are separated and transplanted into other boxes to be taken home.
This was so successful that we devised a big window box which is suited for home use also; it is just as wide as the window and half as long again as it is wide. But this box does not stand outside on the window sill; if it did, the plants would freeze. One end only rests on the inside window sill where it gets the sun; the end is supported by two legs of the same height that the window sill is from the floor.
