La Salle's dream of a New France in the heart of America was blotted out in his tragic death upon the banks of the River Trinity (1687). Yet his mantle was to fall in turn upon the square shoulders of Le Moyne d'Iberville and of his brother—the good, the constant Bienville, who after countless and arduous struggles laid firm the foundations of New Orleans. In the precious treasury of Margry we learn that on reaching Rochelle after his first voyage in 1699 Iberville in these prophetic words voices his faith: "If France does not immediately seize this part of America which is the most beautiful, and establish a colony which is strong enough to resist any which England may have, the English colonies (already considerable in Carolina) will so thrive that in less than a hundred years they will be strong enough to seize all America." [30] But the world-weary Louis Quatorze, nearing his end, quickly tired of that remote and unproductive colony upon the shores of the gulf, so industriously described in Paris as a "terrestrial paradise"; and the "paternal providence of Versailles" willingly yielded place to the monumental speculation of the great financier Antoine Crozat. In this Paris of prolific promotion and amazed credulity, ripe for the colossal scheme of Law, soon to blow to bursting-point the bubble of the Mississippi, the very songs in the street echoed flamboyant, half-satiric panegyrics upon the new Utopia, this Mississippi Land of Cockayne:

It's to-day no contribution

To discuss the Constitution

And the Spanish war's forgot

For a new Utopian spot;

And the very latest phase

Is the Mississippi craze. [31]

Interest in the new colony led to a great development of southwesterly trade from New France. Already the French coureurs de bois were following the water route from the Illinois to South Carolina. Jean Couture, a deserter from the service in New France, journeyed over the Ohio and Tennessee rivers to that colony, and was known as "the greatest Trader and Traveller amongst the Indians for more than Twenty years." In 1714 young Charles Charleville accompanied an old trader from Crozat's colony on the gulf to the great salt-springs on the Cumberland, where a post for trading with the Shawanoes had already been established by the French. [32] But the British were preparing to capture this trade as early as 1694, when Tonti warned Villermont that Carolinians were already established on a branch of the Ohio. Four years later, Nicholson, Governor of Maryland, was urging trade with the Indians of the interior in the effort to displace the French. At an early date the coast colonies began to trade with the Indian tribes of the back country: the Catawbas of the Yadkin Valley; the Cherokees, whose towns were scattered through Tennessee; the Chickasaws, to the westward in northern Mississippi; and the Choctaws farther to the southward. Even before the beginning of the eighteenth century, when the South Carolina settlements extended scarcely twenty miles from the coast, English traders had established posts among the Indian tribes four hundred miles to the west of Charleston. Following the sporadic trading of individuals from Virginia with the inland Indians, the heavily laden caravans of William Byrd were soon regularly passing along the Great Trading Path from Virginia to the towns of the Catawbas and other interior tribes of the Carolinas, delighting the easily captivated fancy and provoking the cupidity of the red men with "Guns, Powder, Shot, Hatchets (which the Indians call Tomahawks), Kettles, red and blue Planes, Duffields, Stroudwater blankets, and some Cutlary Wares, Brass Rings and other Trinkets." [33] In Pennsylvania, George Croghan, the guileful diplomat, who was emissary from the Council to the Ohio Indians (1748), had induced "all-most all the Ingans in the Woods" to declare against the French; and was described by Christopher Gist as a "meer idol among his countrymen, the Irish traders."

Against these advances of British trade and civilization, the French for four decades had artfully struggled, projecting tours of exploration into the vast medial valley of the continent and constructing a chain of forts and trading-posts designed to establish their claims to the country and to hold in check the threatened English thrust from the east. Soon the wilderness ambassador of empire, Céloron de Bienville, was despatched by the far-visioned Galissonière at Quebec to sow broadcast with ceremonial pomp in the heart of America the seeds of empire, grandiosely graven plates of lasting lead, in defiant yet futile symbol of the asserted sovereignty of France. Thus threatened in the vindication of the rights of their colonial sea-to-sea charters, the English threw off the lethargy with which they had failed to protect their traders, and in grants to the Ohio and Loyal land companies began resolutely to form plans looking to the occupation of the interior. But the French seized the English trading-house at Venango which they converted into a fort; and Virginia's protest, conveyed by a calm and judicious young man, a surveyor, George Washington, availed not to prevent the French from seizing Captain Trent's hastily erected military post at the forks of the Ohio and constructing there a formidable work, named Fort Duquesne. Washington, with his expeditionary force sent to garrison Captain Trent's fort, defeated Jumonville and his small force near Great Meadows (May, 1754); but soon after he was forced to surrender Fort Necessity to Coulon de Villiers.

The titanic struggle, fittingly precipitated in the backwoods of the Old Southwest, was now on—a struggle in which the resolute pioneers of these backwoods first seriously measured their strength with the French and their copper-hued allies, and learned to surpass the latter in their own mode of warfare. The portentous conflict, destined to assure the eastern half of the continent to Great Britain, is a grim, prophetic harbinger of the mighty movement of the next quarter of a century into the twilight zone of the trans-Alleghany territory.
