Which of the following most accurately describes the problem?

AN unusual method of transporting liquids in bulk over territory unsuitable for the operation of normal vehicles has been developed by the Four Wheel Drive Auto Co., Clintonville, Wisconsin, U.S.A., for the U.S. Army.

An F.W.D. tractor with special broad low-pressure tyres tows a train consisting of five pairs of 500-gal. rubber cylinders. Measuring 5 frt, high and 3 ft. 6 in. wide, each cylinder is in effect a tyre, and as each pair is connected by a separate

drawbar, a high degree of articulation is afforded.

Total capacity of the train of cylinders is limited only by the power of the prime mover. It is stated that loads can he moved over sand, mud, swampland, boulders and deep snow.

The cylinders were developed by the Goodyear Tire and Rubber Co., Akron, Ohio, and are resistant to chemicals and fuels of up to 40 ner cent, aromatic content. They can be operated in tempera tures of —65° to +125° F. and can be used for storage in temperatures of —80° to +160° F.

Pumps fitted to the tractor may be used to empty or fill the cylinders at a rate of 50-100 g.p.m., and filters are provided for handling aviation spirit. The hydraulic brakes are pneumatically operated and the cylinders can easily be removed from the hubs of each bogie. They can also be run at atmospheric pressure when empty.

As can be seen from the accompanying illustration, the cylinders have chevronpattern lugs to serve as treads.
