_Treaty of 1761._--The hostile course of the Cherokees being still continued, the authorities of South Carolina in 1761 dispatched Colonel Grant with a force sufficient to overcome them. After destroying their crops and fifteen towns he compelled a truce, following which Lieutenant Governor Bull concluded a treaty with them at Ashley Ferry, or Charleston.[22] By this instrument the boundaries between the Indians and the settlements were declared to be the sources of the great rivers flowing into the Atlantic Ocean. In 1767 the legislature of North Carolina made an appropriation and the governor appointed three commissioners for running a dividing-line between the western settlements of that province and the Cherokee hunting grounds.[23] _Treaty and purchase of 1768._--Mr. Stuart, the British superintendent of Indian affairs, on the 14th of October, 1768, concluded a treaty with the Cherokees at Hard Labor, South Carolina. Therein it was agreed that the southwest boundary of Virginia should be a line "extending from the point where the northern line of North Carolina intersects the Cherokee hunting grounds about 36 miles east of Long Island in the Holston River; and thence extending in a direct course north by east to Chiswell's mine on the east bank of the Kenhawa River, and thence down that stream to its junction with the Ohio."[24] This treaty was made in pursuance of appeals from the Indians to stop further encroachments of settlers upon their lands and to have their boundaries definitely fixed, especially in the region of the north fork of Holston River and the headwaters of the Kanawha. _Treaty and purchase of 1770._--The settlements having encroached beyond the line fixed by the treaty of 1768, a new treaty was concluded on the 18th October, 1770, at Lochabar, South Carolina. A new boundary line was established by this treaty commencing on the south bank of Holston River six miles east of Long Island, and running thence to the mouth of the Great Kanawha.[25]
