In point of fact, the only substantial body of statistical information about the naturalization of the foreign-born voter which hitherto has been even ostensibly sufficient for the student as a basis for any racial comparisons, is that gathered by the United States Immigration Commission of 1907. That body, created by an Act of Congress approved February 7, 1907, of which Senator William P. Dillingham of Vermont was chairman, consisted of three Senators, three members of the House of Representatives, and three other persons appointed by the President of the United States, and was directed by the statute to “make full inquiries, examination, and investigation, by sub-committee or otherwise, into the subject of immigration, ...” and to report such conclusions and recommendations as in its judgment might seem proper. The information gathered by this Commission is very voluminous, and has been of great value to sociologists and others concerned with various aspects of the subject. Indeed, its report has come to be called “the bible of the immigration question.” Nearly all the modern writings on the subject have been based upon it in at least a general way, and their color taken largely from its conclusions and its point of view. LEGEND OF “THE NEW IMMIGRATION” To this report is attributable almost entirely the familiar conventional generalization that there is a marked distinction in what might be called _quality of assimilability_, between the immigration of former years and that of the three decades preceding the Great War; between the so-called “old immigration” and the “newer.” This distinction is drawn in the report and, in most of the writings of individuals, based upon it, between the group of races from northern and western Europe--the English-speaking races, the Scandinavians, Germans, Dutch, Belgians, French, and so on, and those from southern and eastern and southeastern Europe, Russia, Austria-Hungary, the Balkan States, Italy, Greece, Turkey-in-Europe, Asia Minor, etc. This _quality of assimilability_ was regarded by the Commission as inferable to a large extent from the degree to which the representatives of these racial groups concerning whom it got information of various kinds were naturalized or had exhibited interest in naturalization at least to the extent of declaring intention to become citizens. It was assumed in a general way that a racial group showing a high proportion of persons who had become citizens, or taken steps thereto, might fairly be regarded as more adaptable to American life, customs and ideals than one in which relatively few naturalized citizens were found. With this assumption as a starting point, it seemed reasonably obvious that inasmuch as the “older” race showed the higher percentage of naturalized persons, the inference of a difference in essential civic quality followed as a matter of course.
