The navy has not only strained every nerve to turn out aviators and to produce airplanes, but the development of improved types of planes has not been overlooked, and we now have abroad several fine types of seaplane as well as airplane. The seaplane is merely an airplane with pontoons, It starts from the ground or from the deck of a vessel. Then there is the flying-boat, developed under naval auspices. This boat takes wing from the water, and is regarded as the most desirable form of aircraft for sea purposes. It is a triumphant instance of our ingenuity, and is built in two sizes, both effective under the peculiar conditions which may dictate the use either of one or the other. The navy has also developed a catapult arrangement for launching seaplanes from the decks of war-ships. This is a moving wooden platform, carrying the seaplane, which runs along a track over the ship's deck. The platform drops into the sea, and the seaplane proceeds on its course through the air.

SCENE AT AN AVIATION STATION SOMEWHERE IN AMERICA, SHOWING FIFTEEN SEAPLANES ON BEACH DEPARTING AND ARRIVING.] The progress of the navy was so great in arranging for the home coast-defense aerial service that Secretary Daniels agreed to establish air coast-patrol stations in Europe, and it was not long before our naval aviators were rendering signal service both along the French and the British coasts. There is the understanding that the United States has already taken the lead in naval aviation, not in quantity, to be sure, but in quality and efficiency, as to which the presence of foreign experts studying our new improvements may be regarded as confirmatory evidence. The Navy Department now has an aircraft factory of its own at Philadelphia, and there flying-boats are now being turned out. Also, five private plants throughout the country are working on navy aircraft exclusively. The Aircraft Board, which succeeded the Aircraft Production Board, is made up in three parts: a third from the navy, a third from the army, and a third civilian. This board is under the joint direction of the Secretaries of War and the Navy. The naval flying-schools are located at Pensacola, Fla., Miami, Fla., Hampton Roads, Va., Bay Shore, L.I., and San Diego, Cal. Some of the aviators are drawn from the regular naval forces, but the great majority are of the reserves, young men from civil life, college men and the like, who have the physical qualifications and the nerve to fly and fight above tumultuous waters.
