"On the other hand, let us not be unjust to labor, for in the American Army in France labor is represented by multitudes of youth upon whose gallantry and steadiness all our hopes of victory depend. No class here at home gives 100 per cent. efficiency or commits itself to 100 per cent. of sacrifice in the winning of the war. Why demand it of the wage earners or the labor unions? "Simply because of its organization and its machinery of leadership, however, labor enjoys an exceptional opportunity to contribute to the winning of the war. This is the first great war in history in which labor has been organized into an economic unit, and that is the reason for some special war problems today which were never encountered by governments in previous wars. But there can be gains even more than losses to the national strength by reason of this organization, if the opportunity be accepted to promote labor's contribution. This is a task especially for the leadership of organized labor. It is certainly no exaggeration to say that in no way can labor be advantaged after the war so much as by the wholehearted acceptance of its opportunity for loyal service to the nation during the war. Let labor splendidly do its part in bringing victory and its future influence will expand beyond the dreams of its prophets.... "Labor and victory are inseparable; nay more, the one may command the other, and thus it may control the fate of the world." INDUSTRIAL MEANING OF WAR Mr. H. E.

Fortunately for our Government, it had the experience of foreign countries to learn from, and learning was an essential part of war preparation in spite of the resources in hand in the United States; as Mr. Coffin said:
