It is doubtless true that we, as a nation, have already acquired too much territory. The result is, the government has become unwieldly, and the danger great that it will break down, sooner or later, of its own weight. So vast is the national domain, and so various is it in its climate, productions, and population, that its central power cannot so legislate as to do equal justice to all interests, and at the same time harmonize the conflict of public sentiment. This state of things had its influence in producing the outbreak of the late Rebellion. For grievances of this character there would seem to be no other remedy than that of revolution. We can but hope, however, that the States now known as the United States will continue to increase in numbers, and to harmonize as one people, one nation, and one government. Yet it is quite possible that the time will come when they will sever into groups and become independent of their present federal relation to each other, in accordance with their peculiar sectional interests, "peaceably if they can, forcibly if they must." Then, instead of one, we shall probably have several independent American confederacies, whose future boundaries are clearly indicated, not only by differences of climate and productions, but by Nature, as marked by her great intervening rivers, lakes, and mountain ranges. These confederacies, when organized, will doubtless consist of those groups of States now known as the Eastern, Western, Southern, and Pacific States. In addition to sectional interests and geographical differences, there are other considerations tending to induce a division of the Union. Among these are an almost unlimited number of political aspirants, and a rapidly increasing population. In Europe, and in many parts of Asia, an overgrown population, in connection with geographical differences and tribal distinctions, is doubtless the original cause which led to subdivisions of empire, and the establishment of so many petty kingdoms as now exist in those countries. The same causes are evidently at work on the American continent, and must ultimately produce similar results. In little more than a century our population has increased from seven to sixty millions. In the next century, at present rates, the increase from natural growth and the influx from foreign emigration will in all probability approximate two or three hundred millions. Europe alone, judging from present indications, will transfer to this continent within that period a large share of that number. If this be assumed as worthy of credence, is it not time that we, as American citizens, should look ahead, as well as go ahead, and if possible, preserve our national character?
