and cut out the door and window openings. Fasten these end pieces between the sides with glue, and also tack them to the uprights of the car (I and J, Fig. 81), which will come just inside of them. The roof is made in two sections (B and C, Fig. 86). For B cut a piece of cardboard twelve and one-quarter by three and three-quarter inches (Fig. 89), draw the curved end with a compass, using the radius shown on the drawing, and slit the corners as indicated by the dotted lines. When this piece has thus been prepared, remove the wire from the top of the truck (see Fig. 81). Bend the cardboard over the sides and ends of the car, and lap corners D and E over F and G, and H and I over J and K, tacking them with thread to hold them in place. To fasten this part of the roof to the top of the car, cut a number of small strips of linen, and glue them to the under side of the roof and to the inside face of the sides and ends of the car (see Fig. 86). The upper portion of the roof C should be made out of a piece of cardboard bent into the shape of Fig. 90, and cut at the ends so the upper portion of C projects a little beyond its sides. Draw the ventilation lights upon the sides of C as shown on the drawings, and then fasten the piece upon the top of B with strips of linen in the same manner as you fastened B in place. C should now have the same curve to its top as B. Cut and glue a piece of cardboard in each end of C to complete the roof. The shape of this piece is shown in Fig. 91. The outer ends of the car should be made as shown in
