But another and more feasible project immediately succeeded. Undiscouraged by Virginia's confiscation of Transylvania, and disregarding North Carolina's action in extending her boundaries over the trans-Alleghany region lying within her chartered limits, Henderson, in whom the genius of the colonizer and the ambition of the speculative capitalist were found in striking conjunction, was now inspired to repeat, along broader and more solidly practical lines, the revolutionary experiment of Transylvania. It was not his purpose, however, to found an independent colony; for he believed that millions of acres in the Transylvania purchase lay within the bounds of North Carolina, and he wished to open for colonization, settlement, and the sale of lands, the vast wilderness of the valley of the Cumberland supposed to lie within those confines. But so universal was the prevailing uncertainty in regard to boundaries that it was necessary to prolong the North Carolina-Virginia line in order to determine whether or not the Great French Lick, the ideal location for settlement, lay within the chartered limits of North Carolina. [192] Judge Henderson's comprehensive plans for the promotion of an extensive colonization of the Cumberland region soon began to take form in vigorous action. Just as in his Transylvania project Henderson had chosen Daniel Boone, the ablest of the North Carolina pioneers, to spy out the land and select sites for future location, so now he chose as leader of the new colonizing party the ablest of the Tennessee pioneers, James Robertson. Although he was the acknowledged leader of the Watauga settlement and held the responsible position of Indian agent for North Carolina, Robertson was induced by Henderson's liberal offers to leave his comparatively peaceful home and to venture his life in this desperate hazard of new fortunes. The advance party of eight white men and one negro, under Robertson's leadership, set forth from the Holston settlement on February 6, 1779, to make a preliminary exploration and to plant corn "that bread might be prepared for the main body of emigrants in the fall." After erecting a few cabins for dwellings and posts of defense, Robertson plunged alone into the wilderness and made the long journey to Post St. Vincent in the Illinois, in order to consult with George Rogers Clark, who had entered for himself in the Virginia Land Office several thousand acres of land at the French Lick. After perfecting arrangements with Clark for securing "cabin rights" should the land prove to lie in Virginia, Robertson returned to Watauga to take command of the migration.
