Hunt up an old pasteboard box, for you will need a box lid about fifteen inches long and eight inches wide as a foundation for the realistic trolley car ([Fig. 76]). Use eight spools for the wheels; place two spool wheels near the front and two near the back on each side. Lay the spools down flat and rest the edge of the box lid on the body of the spools; then stand a row of eleven spools on each side of the top of the box lid. Beginning at one end of the row, build up every other spool into three-spool columns; the intervening spaces form the open windows of the car.
Leave windows on the opposite side of the car in the same way, and place a row of spools close up against the bottom spools of each side of the car to form the car seats. Roof the car with a piece of cardboard cut off square at one end and rounded at the other. On top of each side of this roof place one row of six buttonhole-twist spools, the spools of each row separated equal distances ([Fig. 76]). Stand a spool on the front of the car platform for the motorman's wheel and you have a car like that in the photograph.
When the trolley is taken apart use the spools in building
A Bridge
[Fig. 77] shows that the piers can be built to a good height and be solid and substantial.
Stand three large-sized spools together, forming a triangle, with one point turned to face the opposite pier. This group of three spools is the foundation of one of the two columns, which together form one pier of the bridge.
Fig. 77—The spool bridge.
About two inches distant and on a line with the triangle of spools stand a group of three more spools, and build up each group into a column four spools high. You will need two more columns for the opposite pier of the bridge; build them as you did the first, and place the second pier exactly opposite to and as far from the first as you desire the span should reach—say about fourteen inches.
