A careful exploration of the valley of the Little Tennessee River, from the point where it leaves the mountains to its confluence with the Holston, was made, and the various mound groups were located and surveyed. These were found to correspond down as far as the position of Fort London and even to the island below with the arrangement of the Cherokee "over-hill towns" as given by Timberlake in his map of the Cherokee country called "Over the Hills," [Footnote: Memoirs, 1765] a group for each town, and in the only available spots the valley for this distance affords. As these mounds when explored yielded precisely the kind of ornaments and implements used by the Cherokees, it is reasonable to believe they built them.
