It will first be necessary to procure six uprights, each 7 feet long and 1 inch thick; and nine crosspieces each 21⁄2 feet long and 1 inch thick.
Take a pair of uprights and join them together with three crosspieces—one at each end and the other in the center. The result will be a framework such as is shown in [Fig. 1]. The four remaining uprights must be similarly treated.
Altogether three frames will have been constructed, and they must be hinged together, as shown in [Fig. 2].
Fig. 3.—The platform.
This may be done with either strips of cloth or small metal hinges. The latter may be purchased from any hardware store for a few cents.
It will be noticed that the framework has only three sides. The fourth side is to be occupied by Punch’s platform, which merely consists of a small board about 6 inches wide and 2 feet 6 inches long. An oblong nick 1 inch by 1⁄2 inch should be cut in each side of this platform, as shown both in [Fig. 3] and A, [Fig. 4]. A cut of similar dimensions must also be made 5 feet 6 inches from the ground in both the front uprights of the framework (B, [Fig. 4]). The incisions in the platform dovetail into those in the uprights. To make all quite secure two small catches (A, [Fig. 4]) are fitted to the ends of the platform, and these clamp round the uprights, holding everything firmly in position.

The framework is now complete, and with the exception of the small space above Punch’s platform, should be covered with dark red or green paper cambric, which may be purchased at five or six cents a yard. The width of the cloth will be found just over 2 feet 6 inches, i.e. the same width as a single frame. The best course, therefore, will be to cut the cloth into seven-foot lengths and nail it with small tacks or brads over each frame separately.
