When the vast region known as Louisiana was purchased by President Jefferson, a century ago, the American people knew as little about it as the American colonies knew about the great territory called New France which came under English sovereignty at the end of the French War, fifty years earlier. But however great Louisiana was, and whatever its splendid stretch of gleaming waterway or rugged mountain range, it was sure that the race which now became its master would not shirk from solving the tremendous problems of its destiny. In 1763 the same race had taken quiet possession of New France, including the whole empire of the Great Lakes and all the eastern tributaries of the Mississippi River; in the half-century since that day this race had proved its vital powers of successful exploitation of new countries. In those fifty years a Tennessee, a Kentucky, an Ohio, and an Indiana and Illinois had sprung up out of an unknown wilderness as if a magician's wand had touched, one by one, the falling petals of its buckeye blossoms. Thus, New France had been acquired by a great kingdom, but the power of assimilation lay in the genius of the common people of England's seaboard colonies for home-building and land-clearing. Soon the era of brutal individualism passed from the Middle West and the old Northwest; weak as it was, the young American Republic, in the person of such men as Richard Henderson and Rufus Putnam, threw an arm about the wilderness, while George Rogers Clark, "Mad Anthony" Wayne, and William Henry Harrison settled the question of sovereignty with the red-skinned inhabitants of the land.

Civilization often marched rough-shod into the American Middle West, bringing, however, better days and ideals than those which it harshly crushed. After Anthony Wayne's conquest of Northwestern Indiana at Fallen Timber (near Toledo, Ohio) in 1794 the burst of population westward from Pittsburg and Kentucky to the valley of the Mississippi was marvellous; by the time of the purchase of Louisiana in 1803 the rough vanguard of the race which had so swiftly opened Kentucky and Ohio and Tennessee to the world was crowding the banks of the Mississippi, ready to leap forward to even greater conquests. What these irrepressible pioneers had done they could do again. Those who affirmed that the purchase of Louisiana must prove a failure had counted without their host.

Nothing is of more interest in the great Government expedition of exploration which President Jefferson now sent into the unknown territory beyond the Mississippi than this very fact of vital connection between the leaders of the former movement into the eastern half of the Mississippi Basin and this present movement into its tremendous western half. In a previous story we have shown that the founders of the old Northwest were largely heroes of the French and Indian and the Revolutionary wars; it is now interesting indeed to note that these leaders in Far Western exploration—Meriwether Lewis and William Clark—were in turn heroes of the British and Indian wars, both of them survivors of bloody Fallen Timber, where, on the cyclone's path, Anthony Wayne's hard-trained soldiers made sure that Indian hostility was never again to be a national menace on the American continent.

Meriwether Lewis
Of the Lewis and Clark Expedition

The proposed exploration of Louisiana by Lewis and Clark is interesting also as the first scientific expedition ever promoted by the American Government. For it was a tour of exploration only; the party did not carry leaden plates such as Céloron de Bienville brought fifty years back in those days of gold interwoven with purple, to bury along the tributaries of the Ohio as a claim to land for his royal master and the mistresses of France. There was here no question of possession; Lewis and Clark were, on the contrary, to report on the geography, physiography, and zoölogy of the land, designate proper sites for trading stations, and give an account of the Indian nations. It is remarkable that little was known of Louisiana on these heads. Of course the continent had been crossed, though not by way of the Missouri River route, which had become the great highway for the fur trade. Mackenzie had crossed the continent in the Far North, and Hearne had passed over the Barren Grounds just under the Arctic Circle. To the southward from the Missouri the Spaniards had run to and from the Pacific for two centuries. The commanding position of St. Louis showed that the Missouri route was of utmost importance; the portage to the half-known Columbia was of strategic value, and a knowledge of that river indispensable to sane plans, commercial and political, in the future.

In May, 1804, the explorers were ready to start from St. Louis. They numbered twenty-seven men and the two leading spirits, Lewis and Clark; fourteen of the number were regular soldiers from the United States army; there were nine adventurous volunteers from Kentucky; a half-breed interpreter; two French voyageurs and Clark's negro servant completed the roster. The party was increased by the addition of sixteen men, soldiers and traders, whose destination was the Mandan villages on the Missouri, where the explorers proposed to spend the first Winter.

There is something of the simplicity of real grandeur in the commonplace records of the leaders of this expedition. "They were men with no pretensions to scientific learning," writes Roosevelt, "but they were singularly close and accurate observers and truthful narrators. Very rarely have any similar explorers described so faithfully not only the physical features, but the animals and plants of a newly discovered land. ... Few explorers who did and saw so much that was absolutely new have written of their deeds with such quiet absence of boastfulness, and have drawn their descriptions with such complete freedom from exaggeration."
