In this respect, the war has already rendered a distinct service to this country. No longer can we blind ourselves to the fact that national unity does not exist. Professor William Graham Sumner used often to remark that the United States had no just claim to the name of nation, because of the presence of the negroes within its borders. Whether that particular definition of "nation" is adopted or not, there can be no doubt that real national homogeneity is wholly lacking, and that the negro is by no means the only discordant element. In fact, in many ways the immigration problem is more imminent and menacing than the negro problem: for the negro problem is in a sense static, since it is not aggravated by continuous accessions from without. We know what the negro problem is, and can state it in terms which will be relatively permanent. But the immigration problem presents constantly changing aspects, not only because of its growing numerical proportions, but because of the diversity of its elements, and the uncertainty as to its future developments. One of the striking manifestations of this new recognition of our dangerous situation is the change of front of those who are opposed to the restriction of immigration. The stock answer to the warnings of the restrictionists used to be the assertion that assimilation was taking place with perfectly satisfactory rapidity and completeness. America was the great "melting-pot" of the nations, out of which was to flow--was, in fact, actually flowing--a new and better type of man, purged of all slag and dross. As conclusive proofs of this claim, were advanced all those superficial adaptations to new surroundings which the immigrant and his children make with so much display and gusto. The assimilating power of the American People was asserted to be unlimited, and if there were any hitches in the process, they could all be remedied by distribution. How suddenly has this elaborate erection of analogies, metaphors, and pseudo-arguments been shown up for the flimsy camouflage that it really was! Miss Grace Abbott, the avowed champion of the immigrant, is forced to admit that "unity of religion, unity of race, unity of ideals, do not exist in the United States. We are many nationalities scattered across a continent." Miss Frances Kellor writes a book on _Straight America_, in which she confesses the failure of assimilation in the past, and turns to universal military service as a last resort. Mrs. Mary Antin remains discreetly silent, and Mr. Isaac A. Hourwich is less in the public eye than formerly. * * * * *
