La Salle had learned from the Iroquois about the Ohio River. But the region through which it flowed to the Mississippi remained for a long while an unbroken wilderness. The English settlements on their strip of Atlantic coast, however, and the French settlements in the west, reached gradually out over this territory and met and grappled. Whichever power got and kept the mastery of the west would get the mastery of the continent. The territory of Kentucky, like that of Michigan, was owned by no tribe of Indians. "It was the common hunting and fighting ground of Ohio tribes on the north and Cherokees and Chickasaws on the south." There was indeed one exception to the uninhabited state of all that land stretching betwixt the Alleghanies and the Mississippi. Vincennes, now a town of Indiana, was, after Kaskaskia, the oldest place in the west. This isolated post is said to have been founded by French soldiers and emigrants. Five thousand acres were devoted to the common field. De Vincennes, for whom it was named, was a nephew of Louis Jolliet. And while it is not at all certain that he founded the post, he doubtless sojourned there in the Indiana country during his roving life. A small stockade on the site of the town of Fort Wayne is said to have been built by him. French settlements began to extend southward from Lake Erie to the head waters of the Ohio, like a chain to check the English. Presqu' Isle, now Erie, Pennsylvania, was founded about the same time as Vincennes. A French settler built his house in an inclosure of two or three acres. The unvarying model was one story high, with porches or galleries surrounding it. Wooden walls were filled and daubed with a solid mass of what was called cat-and-clay, a mixture of mortar and chopped straw or Spanish moss. The chimney was of the same materials, shaped by four long corner posts, wide apart below, and nearer together at the top. As fast as children grew up and married they built their cottages in their father's yard; and so it went on, until with children and grandchildren and great-grandchildren, a small village accumulated around one old couple. The French were not anxious to obtain grants of the rich wild land. Every settlement had its common field, large or small, as was desired. A portion of this field was given to each person in the village for his own, and he was obliged to cultivate it and raise food for his family. If a man neglected his ground, it was taken from him. A large tract of land called the common pasture was also inclosed for everybody's cattle to graze in.
