The westward movement of the Caucasian branch of the human family from the high plains of Asia, first over Europe, and thence, with swelling tide, pouring its multitudes into the New World, is the grandest phenomenon in history. What American can contemplate its results, as displayed before him, and as promised in the proximate future, without an emotion of pride and exultation? Our nation has the great middle region of the best continent of the world, and our people are descendants from the most vigorous races. Western Europe, over-peopled, sends us her most energetic sons and daughters, in numbers augmenting with each succeeding decade. Asia is beginning to send forth a portion of her surplus population to our shores. Though of inferior race, the Eastern Asiatics are industrious and ingenious cultivators and artisans. A large influx of these laborers, though it may lower the average character of our people, will, it is hoped, in a greater degree elevate theirs; and thus, while adding to the wealth and power of a nation, do something toward the general amelioration of the race. While, then, we contemplate with patriotic pride the position which, as a nation, we hold in the world's affairs, may we not indulge in pleasant anticipations of the near approach of the time, when the commercial and social heart of our empire will occupy its natural place as the heart of the continent, near the centre of its natural capabilities? New York has long been, and for some decades of years it will continue to be, the necessary chief focal point of our nation. But, in all respects, it is not the true heart. In its composition and dealings, it is almost as much foreign as American. Located on our eastern border, fronting the most commercial and the richest transatlantic nations, and of easy access to extensive portions of our Atlantic coast, it is the best point of exchange between foreign lands and our own, and for the cities of the sea border of our Republic. As Tyre, Alexandria, Genoa, Venice, Lisbon, and Amsterdam, in their best days, flourished as factors between foreigners and the people of the interior regions, whose industries were represented in their markets, so New York grows rich as the chief agent in the exchange-commerce between the ocean shores and the interior regions of our continent. As our numbers have swelled, since we became a nation, from three and a half millions to thirty millions, so New York, including Brooklyn and other suburbs, has increased in population and wealth still more rapidly, to wit, from twenty-five thousand to more than one million. While the nation has increased less than tenfold, New York has grown more than four times tenfold. In 1790 the city of New York contained thirty-three thousand, and the State of New York three hundred and forty thousand--the city having less than one-tenth of the people of the State.
