[013] Olean is situated at the head of navigation of the Allegheny, at the mouth of Olean Creek, in Cattaraugus County, New York. The first settlers came prior to 1805. It was the southern terminus of the Genesee Valley canal (begun in 1836), until in the fifties when that waterway was extended to the Pennsylvania line. The growth of Olean has been rapid since the inception of the oil industry; it now being one of the most important storage and shipping points in the oil fields.--ED.

[016] Charleston, the seat of Kanawha County, West Virginia, is situated on the Great Kanawha, about fifty miles above its mouth. The site was included in a grant made (1772) by Lord Dunmore, royal governor of Virginia, to Thomas Bullitt. In 1786 Bullitt transferred his claim to George Clendenin, who was the first settler on the spot; he built Clendenin's fort in 1786 or 1787.--ED.
