The transformations through which the United States is passing in our own day are so profound, so far-reaching, that it is hardly an exaggeration to say that we are witnessing the birth of a new nation in America. The revolution in the social and economic structure of this country during the past two decades is comparable to what occurred when independence was declared and the constitution was formed, or to the changes wrought by the era which began half a century ago, the era of Civil War and Reconstruction. These changes have been long in preparation and are, in part, the result of world-wide forces of reorganization incident to the age of steam production and large-scale industry, and, in part, the result of the closing of the period of the colonization of the West. They have been prophesied, and the course of the movement partly described by students of American development; but after all, it is with a shock that the people of the United States are coming to realize that the fundamental forces which have shaped their society up to the present are disappearing. Twenty years ago, as I have before had occasion to point out, the Superintendent of the Census declared that the frontier line, which its maps had depicted for decade after decade of the westward march of the nation, could no longer be described. To-day we must add that the age of free competition of individuals for the unpossessed resources of the nation is nearing its end. It is taking less than a generation to write the chapter which began with the disappearance of the line of the frontier--the last chapter in the history of the colonization of the United States, the conclusion to the annals of its pioneer democracy. It is a wonderful chapter, this final rush of American energy upon the remaining wilderness. Even the bare statistics become eloquent of a new era. They no longer derive their significance from the exhibit of vast proportions of the public domain transferred to agriculture, of wildernesses equal to European nations changed decade after decade into the farm area of the United States. It is true there was added to the farms of the nation between 1870 and 1880 a territory equal to that of France, and between 1880 and 1900 a territory equal to the European area of France, Germany, England, and Wales combined. The records of 1910 are not yet available, but whatever they reveal they will not be so full of meaning as the figures which tell of upleaping wealth and organization and concentration of industrial power in the East in the last decade. As the final provinces of the Western empire have been subdued to the purposes of civilization and have yielded their spoils, as the spheres of operation of the great industrial corporations have extended, with the extension of American settlement, production and wealth have increased beyond all precedent.
