What may be called, for want of a better term, the colonial spirit, which is the essence of hyphenism, has persisted in this country to hamper national progress and national unity. Wherever this colonial spirit shows itself it is a menace to be fought, whether the secret or acknowledged attachment binds to England, Ireland, France, Germany, Italy, Greece or any other nation. Jefferson pointed out that we have on this soil evolved a new race of men who may inexactly be called “Americans”. This term, as a monopoly of the United States, is properly objected to by our neighbors, North and South—yet it has a definite meaning for the world. During the Great War one aspect of war duty was to direct the labor activities growing out of the war, to divert labor from “non-essential” to “essential” industry and to arbitrate and mediate on wage matters. It was found necessary to study and to analyze the greatly feared, but infrequently discovered “enemy alien”; and as a preparation for this duty, with the assistance of several hundred local agents, the population of Massachusetts was separated into naturally allied groups based on birth, racial descent, religious, social and industrial affiliations. The astonishing result was that, counting as “native Americans” only the actual descendants of all those living in Massachusetts in 1840, of whatever racial stock prior to that time, only two-sevenths, even with the most liberal classification, came within the group of colonial descent, while the remaining five-sevenths were found in the various racial groups coming later than 1840. More than this: While the “Colonial” group had increased in numbers for three decades after 1840, in 1918 they were found actually to be fewer in number than in 1840, a diminution due to excess of deaths over births, proceeding in increasing ratio. Membership in the Society of Mayflower descendants is eagerly sought as the hallmark of American ancestry. In anticipation of the tercentenary of the Mayflower-coming in 1620, about a dozen years ago a questionnaire was sent to every known eligible for Mayflower ancestry, and the replies were submitted to the experts in one of the national universities for review and report. When this report was presented later, it contained the statement that, considering the prevailing number of marriages in this group, and children per family,—when the six-hundredth celebration of the Pilgrims’ Landing is held in 2220, three hundred years hence, a ship the size of the original Mayflower will be sufficient to carry back to Europe all the then living Mayflower descendants.
