In proving the case for the American scholar, as I think we can prove it, we should not be beguiled into the pleasant task of recording the deeds of scholars and gentlemen when the deeds were those of the gallant gentleman rather than of the scholar _per se_. We have one here in our own academic family whose lieutenant's bars I should be as proud to wear as the stars of any of our generals. Nor need we, I think, cite the instances where the rigorous training of the scholar clearly laid the foundation for great accomplishment in some general field of administration. The man whom we can thank perhaps more than any other for the brilliant conduct of our war finance was seventeen years ago editor-in-chief of the _Columbia Law Review_. We may well turn with pride, but we don't need him to prove our point, to the scholar of this university, formerly president of this Chapter, who, from his own talents and experience and his alert sense of scholarship in others, has earned the place which he now holds as educational director of the largest university in the world, the A.E.F. University at Beaune. * * * * * Our case rests, as I say, upon the direct applications of scholarship, and not only upon their quality, but on their range. A single division of the National Research Council, in its report for 1918, showed work of national significance by the scholars in physics, mathematics, and allied fields toward the solution of no fewer than sixty-eight different problems, every one of which needed for its solution men with training and knowledge and vision. At the outset, who among us had the slightest conception of the complexity of the adaptations to warfare of what was known to modern scholarship? We knew that the war was mounting into the air, but who had any realization of the adjustments which this involved? Fifteen fundamental problems based on pure physics promptly arose with reference to instruments for airplane operation. For example, at night and in the clouds, the aviator must have before his eyes a dial which will indicate the slightest deviation from his course. Seven problems had to do with airplane photography. As the art of camouflage advanced, for instance, color filters had to be devised for its detection from above. Seven additional problems had to do with factors of construction and maintenance, as fuel efficiency. Nine others affected ballooning; and the balloon, as the war developed, came to be of greater and greater importance. Eleven studies were in signalling: one, for example, a device for secret daylight signalling, with a range of five miles or more. And please remember that all these were the task of one branch of one organization within the field of pure science. By common consent, the dullest branch of physics was held to be acoustics, but since 1914 the whole question of sound-ranging has been in the hands of experts in acoustics. A device developed by American physicists gave
