The Indian trade was almost the sole interest in Wisconsin during the two centuries that elapsed from the visit of Nicolet in 1634 to about 1834, when lead-mining had superseded it in the southwest and land offices were opened at Green Bay and Mineral Point; when the port of Milwaukee received an influx of settlers to the lands made known by the so-called Black Hawk war; and when Astor retired from the American Fur Company. These two centuries may be divided into three periods of the trade: 1. French, from 1634 to 1763; 2. English, from 1763 to 1816; 3. American, from 1816 to 1834. FRENCH EXPLORATION IN WISCONSIN.
