[240] The centers of Wisconsin trade were Green Bay, Prairie du Chien, and La Pointe (on Madelaine island, Chequamegon bay). Lesser points of distribution were Milwaukee and Portage. From these places, by means of the interlacing rivers and the numerous lakes of northern Wisconsin, the whole region was visited by birch canoes or Mackinaw boats.
