And this noble man must be likewise a _new_ man,--not merely a migrated European. Western Europe pushed a little farther west does not meet our demand. Why should Europe go three thousand miles off to be Europe still? Besides, can we afford to England, France, Spain, a larger room in the world? Are we more than satisfied with their occupancy of that they already possess? The Englishman is undeniably a wholesome picture to the mental eye; but will not twenty million copies of him do, for the present? It would seem like a poverty in Nature, were she unable to vary, but must go helplessly on to reproduce that selfsame British likeness over all North America. But history fully warrants the expectation of a new form of man for the new continent. German and Scandinavian Teutons peopled England; but the Englishman is _sui generis_, not merely an exported Teuton. Egypt, says Bunsen, was peopled by a colony from Western Asia; but the genius and physiognomy of Egypt are peculiar and its own. Mr. Pococke will have it that Greece was a migrated India: it was, of course, a migration from some place that first planted the Hellenic stock in Europe; but if the man who carved the Zeus, and built the Parthenon, and wrote the "Prometheus" and the "Phaedrus," were a copy, where shall we find the original? Indeed, there has never been a great migration that did not result in a new form of national genius. And it is the thoroughness of the transformations thus induced which makes the chief difficulty in tracing the affinities of peoples. So it is that the world is enriched. Every new form of man establishes another current in those reciprocations of thought, in those electrical streams of sympathy,--of wholesome attraction and wholesome repulsion,--by which the intellectual life is kindled and quickened. Thought begins not until two men meet. Col. Hamilton Smith makes it quite clear that civilization has found its first centres there where two highways of national movement crossed, and dissimilar men looked each other in the face. They have met, it may be, with the rudest kind of greetings; but have obtained good thoughts from hard blows, and beaten ideas _out_ of each other's heads, if not _into_ them, according to the ancient pedagogic tradition. Higher culture brings higher terms of meeting; traffic succeeds war, conversation follows upon traffic; ever the necessity of various men to each other remains. There is no pure white light until seven colors blend; so to the mental illumination of humanity many hues of national genius must consent: and the value of life to all men is greater so soon as a new man has made his advent.
