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.

The men training in the naval aviation-schools are enrolled as Second Class Seamen in the Coast Defense Reserve. Their status is similar to that of the midshipmen at Annapolis. Surviving the arduous course of training, they receive commissions as ensigns; if they do not survive they are honorably discharged, being free, of course, to enlist in other branches of service. The courses last about six months, the first period of study being in a ground school, where the cadets study navigation, rigging, gunnery, and other technical naval subjects. Thence the pupil goes to a flight-school, where he learns to pilot a machine. Here, if he comes through, the young cadet is commissioned as an ensign. All pilots in the Naval Reserve Flying Corps hold commissions, but not all of the pilots in the regular navy are commissioned officers, a few rating as chief petty officers.

The men who act as observers—who accompany the pilots on their trips, taking photographs, dropping bombs and the like—are not commissioned. They are selected from men already in the service, regular seamen, marines, reserves, or volunteers. Of course, these men have their opportunities of becoming pilots. The United States seaplanes carry extremely destructive weapons, which will not be described until after the war. The Germans, it may be assumed, know something about them.

The spirit of our naval pilots, both students and qualified graduates, is of the highest, and foreign naval officers have been quick to express their appreciation of their services. When Ensign Curtis Read was shot down in February, 1918, while flying over the French coast, his funeral was attended by many British army and navy officers, and by representatives of both branches of the French service. Besides the company of American sailors there were squads of French and British seamen, who marched in honor of the young officer. The city of Dunkirk presented a beautiful wreath of flowers.

"Nothing," wrote Ensign Artemus Gates, captain-elect of Yale's 1917 football eleven, and a comrade of Read's in France, to the young officer's mother, "could be more impressive than to see a French general, an admiral, British staff-officers, and many other officers of the two nations paying homage."

The death of Ensign Stephen Potter, who was killed in a battle with seven German airplanes in the North Sea on April 25, 1918, followed a glorious fight which will live in our naval annals. Potter was the first of our naval pilots to bring down a German airplane, and indeed may have been the first American, fighting under the United States flag, to do this. His triumph was attained on March 19, 1918. Between that time and his death he had engaged in several fights against German airmen, causing them to flee.

And in this country our course of training has been marked by many notable examples of heroism and devotion, none more so than the act of Ensign Walker Weed, who, after his plane had fallen in flames at Cape May, N.J., and he had got loose from his seat and was safe, returned to the burning machine and worked amid the flames until he had rescued a cadet who was pinned in the wreckage. It cost Weed his life, and the man he rescued died after lingering some days; but the act is none the less glorious because the gallant young officer gave his life in vain.

Related to the aviation service, to the extent at least that they observe from an aerial post, are the balloon men of the navy, officers who go aloft with great gas-bags, which, when not in use, are carried on the decks of the larger war-ships engaged in work. From the baskets of these sausage-shaped balloons the observers, armed with telescopes and binoculars, the ocean and the ships of the convoy lying like a map below, sweep the surface of the water for lurking submarines and enemy raiders. The balloons are attached to the war-ships, and are towed along through the air. Just how effective this expedient is, is known only to the Navy Department, but the fact that it is retained argues for its usefulness.
