The operation of the Selective Draft law provided a simultaneous opportunity for a display of patriotism. Acting under its provisions, the President in a stirring proclamation issued on May 18, 1917, called upon every man in the country between the age of 21 and 30 to register his readiness to be called upon for army service at the designated registration place within the precinct where he permanently resided. It was a call to the nation to arm.

"The power against which we are arrayed," the President said, "has sought to impose its will upon the world. To this end it has increased armament until it has changed the face of war. In the sense in which we have been wont to think of armies, there are no armies in this struggle, there are entire nations armed. Thus, the men who remain to till the soil and man the factories are no less a part of the army that is in France than the men beneath the battle flags. It must be so with us. It is not an army that we must shape and train for war; it is a nation.

"To this end our people must draw close in one compact front against a common foe. But this cannot be if each man pursues a private purpose. All must pursue one purpose. The nation needs all men; but it needs each man, not in the field that will most pleasure him, but in the endeavor that will best serve the common good. Thus, though a sharpshooter pleases to operate a trip hammer for the forging of great guns and an expert machinist desires to march with the flag, the nation is being served only when the sharpshooter marches and the machinist remains at his levers.

"The whole nation must be a team, in which each man shall play the part for which he is best fitted. To this end, Congress has provided that the nation shall be organized for war by selection; that each man shall be classified for service in the place to which it shall best serve the general good to call him.

"The significance of this cannot be overstated. It is a new thing in our history and a landmark in our progress. It is a new manner of accepting and vitalizing our duty to give ourselves with thoughtful devotion to the common purpose of us all. It is in no sense a conscription of the unwilling; it is, rather, selection from a nation which has volunteered in mass. It is no more a choosing of those who shall march with the colors than it is a selection of those who shall serve an equally necessary and devoted purpose in the industries that lie behind the battle line."

The President had strongly espoused the selective draft in preference to the voluntary system of raising an army organization. He had pointed out that many forms of patriotic service were open to the people, and emphasized that the military part of the service, important though it was, was not, under modern war conditions, the most vital part. The selective draft enabled the selection for service in the army of those who could be most readily spared from the pursuit of other industries and occupations. There being a universal obligation to serve in time of war, the Administration felt the need of being empowered to select men for military service and select others to do the rest of the nation's work, either by keeping them in their existing employment, if that employment was useful for war purposes, or utilizing their services in a like field.

"The volunteer system does not do this," he said. "When men choose themselves they sometimes choose without due regard to their other responsibilities. Men may come from the farms or from the mines or from the factories or centers of business who ought not to come but ought to stand back of the armies in the field and see that they get everything that they need and that the people of the country are sustained in the meantime."

Registration day, which was fixed for June 5, 1917, partook of the character of an election day. The young manhood of the country of the prescribed ages trooped to the registration places of their districts like voters depositing ballots at polling booths. It was a national roll call of the pick of civilian manhood available for military duty, and yielded an enrollment of 9,649,938 from which the first army was to be drafted.

"The registration," reported the Government, "was accomplished in a fashion measuring up to the highest standards of Americanism. The young men came to the registration places enthusiastic; there was no hint of a slacking spirit anywhere, except in a few cases where misguided persons had been prevailed upon to attempt to avoid their national obligation."

The machinery for the selective draft had merely been started. Only the groundwork had been laid. The principal operation—the draft itself—had to be undertaken, and the process was a slow one. Half the men who registered claimed exemption from military service for a multitude of reasons, but as not more than 6 per cent were to be chosen to compose the first citizen army, this was not important even if most of the exemption claims were justified and allowed.
