"There are accepted definitions of Americanism. There is none of Americanization. The reason is not hard to find. There is in America a national impulse called Americanization, which was understood as a war necessity before it had developed in time of peace. It acquired a generalization before it had become specific. It was subjected to organization and committed to the achievement of results before it was a branch of knowledge fairly evolved and reduced to practice. There is no science of race assimilation. No nation has had a sufficiently free opportunity with many diverse races to establish its enduring principles and certain procedure. America has this opportunity in her thirty-five different races speaking fifty-four languages, of whom 13,000,000 are foreign-born. One third of her total population has its roots in other soils and in diverse cultures. She has the laboratory for the experiment in her wide expanse of territory, much of it still unsettled; in the elasticity of her institutions; and in the still formative state of her cultural life. The old world is engaged in a struggle to find a way by which each race living on its own soil, separated by definite national boundaries, can be assured freedom and peace in the full development of its national life and in the realization of international opportunities. The task of America is different. It is for her to find the way by which these races, living on one soil, under one form of government, with no territorial lines, can be assimilated and become a part of her integral national life."
