The cab is to be made apart from the truck and is to fit upon the base, as shown in [Figs. 1 and 2]. It is fixed into place by four screws and can be removed easily for examination of the locomotive mechanism. The dimensions for the cab are shown in [Figs. 8 and 9], and may be varied by the builder.

Sheet metal or wood may be used in the construction, and the joints soldered on the inside or riveted, as shown in the illustration. The window and door openings may be cut out or painted on. Small bells may be mounted on the ends of the cab, adding to its appearance. The headlights shown in [Figs. 1 and 2] may be cut from wood or made of sheet metal. Light bulbs may be installed, and their voltage should correspond to that of the motive energy. The terminals for the sockets of the headlight lamps should be connected to the frame of the truck and to the spring, which bears upon the brass collars on the wheels, which are insulated from the axles, as shown at A, [Fig. 3].
This completes the locomotive in all essential details and it is ready to be placed upon the track to be tested. The track system will be considered in a subsequent [article].
Mixing Paste
When flour paste becomes watery upon cooling, it is evidence that the mixture has been boiled too long. Only the best flour should be used for making paste. Many paper hangers do not boil paste. They make a stiff batter with lukewarm water, stirring out all lumps, and then briskly stir in boiling water. When the mass thickens continue stirring, but add no more hot water. Pour a little cold water on top and set the paste away to cool.—Contributed by A. A. Kelly, Malvern, Pa.
