This, then, is the great historic significance of the movement of continental expansion, in which the Louisiana Purchase was the most striking single achievement. It stands out in marked relief even among the feats of a nation of pioneers, a nation whose people have, from the beginning, been picked out by a process of natural selection from among the most enterprising individuals of the nations of western Europe. The acquisition of the territory is a credit to the broad and far-sighted statesmanship of the great statesmen to whom it was immediately due, and, above all, to the aggressive and masterful character of the hardy pioneer folk to whose restless energy these statesmen gave expression and direction, whom they followed rather than led. The history of the land comprised within the limits of the Purchase is an epitome of the entire history of our people. Within these limits we have gradually built up State after State, until now they many times over surpass in wealth, in population, and in many-sided development the original thirteen States as they were when their delegates met in the Continental Congress. The people of these States have shown themselves mighty in war with their fellow-man and mighty in strength to tame the rugged wilderness. They could not thus have conquered the forest, the prairie, the mountain and the desert, had they not possessed the great fighting virtues, the qualities which enable a people to overcome the forces of hostile men and hostile nature. On the other hand they could not have used aright their conquest had they not in addition possessed the qualities of self-mastery and self-restraint, the power of acting in combination with their fellows, the power of yielding obedience to the law and of building up an orderly civilization. Courage and hardihood are indispensable virtues in a people, but the people which possess no others can never rise high in the scale either of power or of culture. Great peoples must have in addition the governmental capacity which comes only when individuals fully recognize their duties to one another and to the whole body politic and are able to join together in feats of constructive statesmanship and of honest and effective administration. The old pioneer days are gone with their roughness and their hardship, their incredible toil and their wild, half-savage romance. But the need for the pioneer virtues remains the same as ever. The peculiar frontier conditions have vanished; but the manliness and stalwart hardihood of the frontiersman can be given even freer scope under the conditions surrounding the complex industrialism of the present day.
