Whilst disputes were maturing themselves into the great national contest between the mother-country and the colonies, the colonies were not altogether at peace among themselves; the question of boundary being fruitful in controversy. Pennsylvania and Connecticut quarrelled violently about the possession of the Wyoming Valley, on the Upper Susquehanna, and blood was even shed. Virginia quarrelled with Pennsylvania, also, about her western frontier, laying claim to Pittsburg and the whole district west of the Laurel Mountains. The boundary dispute which had long agitated New York and New Jersey was happily adjusted about this time, as was also that between New York and Massachusetts. Violent were the disputes, however, between New York and the settlers in the infant Vermont, the territory lying west of the Connecticut, “the Green Mountain Boys,” as they were called, and the leaders of whom were Ethan Allen and Seth Warner, emigrants from Connecticut to the Green Mountains. But, spite of disputes both at home and abroad, settlers extended themselves farther and still farther, to the north and to the west. The formidable Six Nations had now disposed of all their vast territory south of the Ohio, as far as the Cherokee or Tennessee River, to the British Crown, for the sum of £10,460. Settlers were already occupying the banks of the Kenhawa River, flowing north into the Ohio, beyond the great Allegany Range. In consequence of this immense cession of territory, land companies started up in England for the establishment of new colonies, but the growing troubles with the mother-country prevented their plans being carried out.
