The Pulley Wheel. One can cover should be converted into a pulley by winding several turns of string around it, near each edge, leaving a groove between the string. Coat the string with glue to make it stick fast to the cover.
The Water-motor Case. [Figure 70] shows how the water-motor case is constructed by fastening boards N, I, J, K, L, and M to the wheel supports G. There must be a slot through I and another through J, for the string belt to pass through, and a hole through K for the intake of water from a faucet. These can be cut out of the edges of the boards, as shown, before they are nailed in place. Leave an opening between boards N and M, and the bottom of ends G, for an outlet for waste water.

A HOME-MADE TOY RAILWAY
Fig. 75.—Upright.
It is often thought that a toy railway is beyond a boy's ingenuity to construct, whereas, in reality, it is one of the simplest toys he can make. This applies to the tracks, stations, and cars of every description, all of which can be made with a few strips of wood, some spools, nails, cardboard, and a bottle of glue, for materials. If you have passed the age of caring for such toys as this, you will, no doubt, enjoy the making of one for your younger brother, or for one of your boy relatives.
