Fig. 385 shows part of the car and gives the necessary measurements. Side R is made of stripwood, ¼ inch by ¼ inch. The gates at each end are made of strips of cardboard. Four screw-eyes are placed in the corner posts for hanging the car to trolley (see Fig. 382). Pieces of thread are tied to the screw-eyes at H and G, and pass through screw-eyes in the supports (T and U in Fig. 382). Two windlasses can be made to stand on M and L, similar to the winding gear described in making the crane (Chapter V), by means of which the car can be drawn backward and forward. The bridge may stand across a piece of cardboard painted to represent a river.
