The Cherokees by this treaty also relinquished all claim they might have to the Long Island or Great Island, as it was sometimes called, of Holston River. This island was in reality outside the limits of the country assigned the Cherokees by the first treaty between them and the United States, at Hopewell, in 1785, but they had always since maintained that no cession had ever been made of it by them, and it was deemed wise to insert a specific clause in the treaty under consideration to that effect.[167] _Boundaries to be surveyed._--Early in 1807[168] the Secretary of War notified Agent Meigs that Mr. Thomas Freeman had been appointed to survey and mark the boundary line conformably to both the treaty of 1805 with the Chickasaws and of 1806 with the Cherokees, as well as to survey the land ceded between the south line of Tennessee and the Tennessee River, lying west of the line from about the Chickasaw Old Fields to the most eastern source of Duck River. He was also advised that General Robertson and himself had been designated to attend and superintend the running of such boundary lines. Furthermore, that it was desirable that the eastern line of both cessions should be one and the same, for although by the Chickasaw treaty the whole waters of Elk River were included, it was evident their claim to any lands east of the line agreed upon by the Cherokees was more than doubtful; that, therefore, the United States ought not to insist on such a line as would go to the eastward of the one defined in the Cherokee treaty, unless the latter could be prevailed upon to extend the same, in which event they were authorized to offer the Cherokees a moderate compensation therefor. EXPLANATORY TREATY NEGOTIATED. This led, upon the assembly of the commissioners and surveyor at Chickasaw Old Fields, in the fall of 1807 (for the purpose of surveying and marking the boundary lines in question), to the negotiation of an explanatory treaty with certain of the Cherokee chiefs, on the 11th of September, 1807,[169] whereby it was agreed that the Cherokee cession line should be extended so far to the eastward as to include all the waters of Elk River and thereby be made coincident and uniform with the Chickasaw line. _Secret article._--The ostensible consideration paid for this concession, as shown by the treaty, was $2,000; but it was secretly agreed that $1,000 and two rifles should be given to the chiefs with whom the treaty was negotiated.[170] President Jefferson transmitted this latter treaty to the Senate on the 29th of March, 1808, and having received the consent of that body to its ratification, it was proclaimed by the President on the 22d of April following.
