of the regard in which the admiralty of Great Britain held this American officer, witness the fact that upon one occasion when the British commander-in-chief of naval operations on the Irish coast was compelled to leave his command for a period, Admiral Sims was nominated by the admiralty to serve as chief of the combined forces until the British commander returned.

But this mission of Admiral Sims, and the eventual despatch of submarine flotillas to the war zone, were but two phases of the enormous problem which confronted the Navy Department upon the outbreak of hostilities. There was first of all the task of organizing and operating the large transport system required to carry our share of troops overseas for foreign service. Within a month after the President had announced that troops would be sent to Europe the first contingent had been organized, and all its units were safely landed in France before the 4th of July. These included a force of marines under Colonel (now Brigadier-General) Charles A. Doyen, which is serving in the army under Major-General Pershing. Since that time a constant stream of troops and supplies has poured across the Atlantic under naval control and supervision, the presiding officer in charge of transport being Rear-Admiral Albert Gleaves.

Then, again, the United States took over control of most of the patrol of the western Atlantic. Our thousands of miles of coast had to be guarded against enemy attack and protected against German raiders. A squadron under command of Admiral William B. Caperton was sent to South America and received with the utmost enthusiasm at Rio de Janeiro, at Montevideo and Buenos Aires, which cities were visited on invitation from the governments of Brazil, Uruguay, and Argentina. After Brazil's entrance into the war the Brazilian Navy co-operated with our vessels in the patrol of South American waters.

The taking over of some 800 craft of various kinds, and their conversion into types needed, provided the navy with the large number of vessels required for transports, patrol service, submarine-chasers, mine-sweepers, mine-layers, tugs, and other auxiliaries. The repair of the 109 German ships whose machinery had been damaged by their crews—details of which will be treated in a subsequent chapter—added more than 700,000 tons to our available naval and merchant tonnage, and provided for the navy a number of huge transports which have been in service for nearly a year. Hundreds of submarine-chasers have now been built, and a number of destroyers and other craft completed and placed in service. The first merchant ship to be armed was the oil-tanker Campana; guns manned by navy men were on board when she sailed for Europe, March 12, 1917. The big American passenger-liners St. Paul and New York were armed on March 16 of that year, and the Red Star liner Kroonland and the Mongolia on March 19. And continuously up to the present writing merchant ships as they have become available have been armed and provided with navy gun crews. Since the arming of the Campana more than 1,300 vessels have been furnished with batteries, ammunition, spare parts, and auxiliaries.

But of equal importance, greater importance history may decree it, was Secretary Daniels's action in 1915 of appointing the Naval Advisory Board of Inventions. That was looking ahead with a vengeance. The idea was to make available the latent inventive genius of the country to improve the navy. The plan adopted by Secretary Daniels for selecting this extraordinary board included a request to the eleven great engineering and scientific societies of the country to select by popular election two members to represent their society on the board. Results were immediately gratifying. Nominations were forthcoming at once, and in September of 1915 the board, which came popularly to be known as the Inventions Board, met in Washington for organization. Thomas A. Edison was selected by the Secretary of the Navy as chairman of the board, and the other members were elected as follows:

From the American Chemical Society: W. R. Whitney, director of Research Laboratory, General Electric Company, where he has been the moving spirit in the perfection of metallic electric-lamp filaments and the development of wrought tungsten. L. H. Baekeland, founder of the Nepera Chemical Company and inventor of photographic paper.

From the American Institute of Electrical Engineers: Frank Julian Sprague, consulting engineer for Sprague, Otis, and General Electric Companies and concerned in the establishment of the first electrical trolley systems in this country. B. G. Lamme, chief engineer of the Westinghouse Electric and Manufacturing Company and a prolific inventor.
