The French explorers saw the river, but failed to grasp its significance as a strategic line in the conquest of the West. Entangled in the water labyrinth of the vast interior, and kindled with aspirations to reach the "Sea of the West," their fur traders and explorers pushed their way through the forests of the North and across the plains of the South, from river to lake, from lake to river, until they met the mountains of the West. But while they were reaching the upper course of the Missouri and the Spanish outposts of Santa Fe, they missed the opportunity to hold the Ohio Valley, and before France could settle the Valley, the long and attenuated line of French posts in the west, reaching from Canada to Louisiana, was struck by the advancing column of the American backwoodsmen in the center by the way of the Ohio. Parkman, in whose golden pages is written the epic of the American wilderness, found his hero in the wandering Frenchman. Perhaps because he was a New Englander he missed a great opportunity and neglected to portray the formation and advance of the backwood society which was finally to erase the traces of French control in the interior of North America. It is not without significance in a consideration of the national aspects of the history of the Ohio Valley, that the messenger of English civilization, who summoned the French to evacuate the Valley and its approaches, and whose men near the forks of the Ohio fired the opening gun of the world-historic conflict that wrought the doom of New France in America, was George Washington, the first American to win a national position in the United States. The father of his country was the prophet of the Ohio Valley. Into this dominion, in the next scene of this drama, came the backwoodsmen, the men who began the formation of the society of the Valley. I wish to consider the effects of the formation of this society upon the nation. And first let us consider the stock itself. The Ohio Valley was settled, for the most part (though with important exceptions, especially in Ohio), by men of the Upland South, and this determined a large part of its influence in the nation through a long period. As the Ohio Valley, as a whole, was an extension of the Upland South, so the Upland South was, broadly speaking, an extension from the old Middle Region, chiefly from Pennsylvania. The society of pioneers, English, Scotch-Irish, Germans, and other nationalities which formed in the beginning of the eighteenth century in the Great Valley of Pennsylvania and its lateral extensions was the nursery of the American backwoodsmen. Between about 1730 and the Revolution, successive tides of pioneers ascended the Shenandoah, occupied the Piedmont, or up-country of Virginia and the Carolinas, and received recruits from similar peoples who came by eastward advances from the coast toward this Old West.
