They are protected by aeroplanes, flying above, that keep watch of any large movements.
They are backed by 4,000,000 men in reserve and training who keep the trenches filled with fighting men, as 10,000 to 20,000 daily retire to mother earth, to the hospitals, or to the camps of the imprisoned.

On the North Sea and the English Channel they are supported by fleets of battleships, cruisers, submarines, and torpedo boat destroyers that occasionally "scrap" with each other, the German boats now and then attacking the English coast and harbors and the English boats now and then assisting to mow down the German troops when they approach too near the coast.

But the great dread and key to this naval warfare is the modern submarine.
Submarines, aeroplanes, and motor busses are three elements of warfare never before put to the test; and the greatest of these thus far is the gasolene motor-car.

By this alone Germany may be defeated.

France and England are rich in gasolene motor power, and supplies from America are open to them.
