The third is Ouiconsin, one hundred and twenty miles further up, navigable two hundred miles. A bend in this river, near its head waters, passes so near to a bend in Fose river, which empties into Green Bay, a branch of Lake Michigan, that the portage is said to be only one mile and three quarters, forming another easy communication between the Mississippi and the lakes. The fourth, Black river, one hundred and fifty miles further, and navigable one hundred miles. The fifth, is the river Chippeway, sixty-five miles above Black river, and navigable one hundred miles.
