The first response from the country to the act of Congress in declaring a state of war came in the form of offers of services from the people, and for weeks there poured into the War Department an almost bewildering stream of letters and visitors offering service of every kind. Without distinction of age, sex, or occupation, without distinction of geographical location or sectional difference, the people arose with but one thought in their mind, that of tendering themselves, their talents, and their substance for the best use the country could make of them in the emergency. Organizations and associations sprang up over night in thousands of places, inspired by the hope that collective offers and aggregations of strength and facilities might be more readily assimilated by the Government; and benevolent and philanthropic societies began to form for the purpose of taking up as far as might be the vicarious griefs which follow in the train of military operations. There was at the outset some inevitable crossing of purposes and duplication of effort, and perhaps there may have been some disappointment that a more instantaneous use could not be made of all this wealth of willingness and patriotic spirit; but it was a superb and inspiring spectacle.

The several Government departments, the Council of National Defense, and other agencies of a more or less formal character subdivided the work of organization. Congress rapidly perfected its legislative program, and in a few weeks very definite direction began to appear in the work of preparation. [Sidenote: Act to increase Military Establishment.] The act of May 18, 1917, entitled "An act to authorize the President to increase temporarily the Military Establishment of the United States," looked to three sources for the Army which it created: [Sidenote: Regular Army to be increased.]
