Our scholars of the coöperative type not only pursued their researches, but they got their military associates into the habit of thinking in terms of scholarship. One of their most useful accomplishments, initiated by a Doctor of Philosophy of this University, was the organization of Thursday evening conferences for the discussion of the new scientific and technical problems facing the Army and Navy. This furnished a nucleus for the exchange of ideas between the different research groups, both here and abroad; for scholarship was mobilized and utilized in France, England, and Italy, as well as here, and our Allies laid their scientific discoveries before us with the greatest loyalty. At these conferences their reports were discussed and digested and applied, instead of being pigeon-holed at the War College, as I fear might have been otherwise the case. It was as a result of one of these conferences that a member of this Chapter, acting on a hint which came from a French report, was largely instrumental in developing a method of submarine detection through sound-waves of a particular type, which, though it came too late to be of service in the war, may serve in peace to relieve the greatest terror of the mariner, the danger of collision in darkness or fog with sister vessel or iceberg or derelict. A potent factor in breaking down the barriers and delays of departmental jealousies and bureaucratic tradition all along the line was the free-masonry of the company of scholars in Washington.
