A chance acquaintance formed by Daniel Boone, during the French and Indian War, with the Irish lover of adventure, John Findlay, [95] was the origin of Boone's cherished longing to reach the El Dorado of the West. In this slight incident we may discern the initial inspiration for the epochal movement of westward expansion. Findlay was a trader and horse peddler, who had early migrated to Carlisle, Pennsylvania. He had been licensed a trader with the Indians in 1747. During the same year he was married to Elizabeth Harris, daughter of John Harris, the Indian-trader at Harris's Ferry on the Susquehanna River, after whom Harrisburg was named. During the next eight years Findlay carried on his business of trading in the interior. Upon the opening of the French and Indian War he was probably among "the young men about Paxtang who enlisted immediately," and served as a waggoner in Braddock's expedition. Over the camp-fires, during the ensuing campaign in 1765, young Boone was an eager listener to Findlay's stirring narrative of his adventures in the Ohio Valley and on the wonderfully beautiful levels of Kentucky in 1752. The fancies aroused in his brooding mind by Findlay's moving recital and his description of an ancient passage through the Ouasioto or Cumberland Gap and along the course of the Warrior's Path, inspired him with an irrepressible longing to reach that alluring promised land which was the perfect realization of the hunter's paradise. Thirteen years later, while engaged in selling pins, needles, thread, and Irish linens in the Yadkin country, Findlay learned from the Pennsylvania settlers at Salisbury or at the Forks of the Yadkin of Boone's removal to the waters of the upper Yadkin. At Boone's rustic home, in the winter of 1768-9, Findlay visited his old comrade-in-arms of Braddock's campaign. On learning of Boone's failure during the preceding year to reach the Kentucky levels by way of the inhospitable Sandy region, Findlay again described to him the route through the Ouasioto Gap traversed sixteen years before by Pennsylvania traders in their traffic with the Catawbas. Boone, as we have seen, knew that Christopher Gist, who had formerly lived near him on the upper Yadkin, had found some passage through the lofty mountain defiles; but he had never been able to discover the passage. Findlay's renewed descriptions of the immense herds of buffaloes he had seen in Kentucky, the great salt-licks where they congregated, the abundance of bears, deer, and elk with which the country teemed, the innumerable flocks of wild turkeys, geese, and ducks, aroused in Boone the hunter's passion for the chase; while the beauty of the lands, as mirrored in the vivid fancy of the Irishman, inspired him with a new longing to explore the famous country which had, as John Filson records, "greatly engaged Mr. Findlay's attention."
