Santos-Dumont had his motor control so arranged that he could regulate the supply of gasoline by his foot. The spark switch may be placed on the steering lever. These controls may be arranged differently, however, with other motors.

It is of prime importance that the motor should be perfectly balanced. It should be direct connected to the axle holding the propeller. The gasoline reservoir is located behind the pilot's seat, the fuel being forced up into a smaller one just above the motor. In his remarkable flight from St. Cyr to Buc, the inventor of the monoplane used a two-cylinder Darraeq motor of 20 hp., which gave the propeller 1000 r.p.m. It weighed a little over 99 Ib. The entire machine weighed 260 Ib. without the pilot. At the end of the crankshaft, opposite the propeller, is a pinion and eccentric working the oil pumps. This pinion also meshes with the gear which operates the water pumps. The cams which raise the valves at the same time operate the magneto. The radiator, which is composed of a great many small copper tubes connected up to a larger tube at the front and rear, is placed under the main surface of the wings and extends from the front to the rear of the planes.



 

A razorless shaving outfit, consisting of a sponge, two measures, a shaving cup, and a powder the mere application of which (mixed with water) removes the hair as faultlessly as the best razor, has just been introduced as the latest tonsorial discovery. The fact that it is warranted to contain no acids, give out no offensive odor, and accomplish shaving without danger of cutting, might persuade some shavers to contemplate substituting it for the time-worn razor. The powder is, however, only for post mortem shaving.
