I need not tell you what lay back of this great movement of men and material. It is not invidious to say that back of it lay a supporting organization of the industries of the country and of all its productive activities more complete, more thorough in method and effective in result, more spirited and unanimous in purpose and effort than any other great belligerent had been able to effect. We profited greatly by the experience of the nations which had already been engaged for nearly three years in the exigent and exacting business, their every resource and every executive proficiency taxed to the utmost. We were their pupils. But we learned quickly and acted with a promptness and a readiness of cooperation that justify our great pride that we were able to serve the world with unparalleled energy and quick accomplishment.
