A sliding bottom or tray is required for cleaning purposes; this is of ¼ in. board, and is nailed to the strip that fits between the rails in front; other strips about 1 in. wide are nailed on the upper side at the extreme ends and back edge to form a tray for the sand, runners being put in against the lower end rails. The front strip is treated with the split, and to draw out the tray, the door may be slightly raised to admit the fingers to push it forward from the inside. Two additional perches put across from the wires, and fixed with staples, give strength to the front and back.
The aviary is now gone over with fine glass-paper, all white places being touched up with the stain and nicely varnished, with the exception of the perches. The aviary will stand on a table, but may be hung from the ceiling if desired. For hanging purposes, four screw-eyes are put in the top, two on the ridge, about 3 in. from the front and back, and one towards each end, placed midway to catch the rails. The four ceiling hooks should screw into the joists, the aviary being suspended with chains.
