When a nice warm day comes, the other end of the box is pushed out of the window and the sash closed down on it to keep it from falling out. A couple of cleats or nails in the window jamb help to hold it in place.
Of course, the box has to be watched and taken in if it turns cold, but it's astonishing how much can be raised and how much more can be learned out of season by the school desk boxes and the home window sliding boxes.
Try it and see for yourself.
The children can learn as much about some things from a box 2X1 ft. as they can from a children's garden. Here are a couple of samples of what the kids themselves in a city school think of it.

"VAN ALST AVE., ASTORIA, QUEENS
"I inclose a few compositions that were written by some of our boys and girls of the Fourth Year. You will recognize the descriptions of your Garden Trays for classroom use Unfortunately the free space in the classroom is limited, so we have found it necessary to allow each pupil only part of a box.
"The children themselves are delighted, as you can see by their compositions.
"Very sincerely yours, (Signed)"
