A device for holding easily a large number of window plants is thus mentioned by Forest and Stream:

Among the not expensive window gardens we may name a device we used in our own sitting-room, which we called an " adoptive case " as we made it a receptacle to receive our flower pots, and our experiment not being patented, and not beyond the c6n-stractive genius of the village carpenter, of course any one who chooses can have one made to order. Our window shelf being six inches only in width, we had a box made that would just fit into our window, of the following dimensions: The length of the box was three feet, the depth fourteen inches, and the width fourteen inches. Into this box we had a zinc pan placed, made so it would just fit the inside of four inches in depth. This box was to receive a drainage of surplus water from the plants, had a hole to draw off dirty or surplus water from the end, and was stopped with a wooden stop - per. A box of this kind, properly made and attended to, would not need drawing off perhaps during a winter, and I am speaking of the winter treatment of plants now.

Having placed the zinc pan within the box, fill the same with tolerably small bits of broken crock until it is even with the top of the pan; then cover the top of this pan with a thin piece of board (pasteboard will do), in which holes are bored, and then place your composition of earth for your plants; set out your plants, choosing those of any of the species you may wish, and at once commence your study and treatment of the same. With such a simple box as this you may grow not only our native American ferns, but add to them from time to time, as your progress in knowledge increases.
