When in 1634 Jean Nicollet visited the Wisconsin country the French advance into the upper Northwest had begun.[2] From 1658 to 1660 Radisson and Groseilliers wandered among the tribes and brought the first canoe loads of furs to Canada from the far West. Then along with the missionaries, Hennepin and Marquette, came the _coureurs des bois_, Nicholas Perrot and Daniel Greyloson Duluth. It is unnecessary to recite in detail the exploits of these Frenchmen and their successors.[3] For a century the songs of unknown boatmen rose from the waters of the western rivers; unknown traders smoked in the lodges of Sioux and Chippewas; and hardy wanderers whose feats of discovery are unrecorded, leaving behind the Missouri River, saw from afar the wonders of the "Shining Mountains".[4] But if no record of them remains, their influence was lasting. Living with the natives, supplying their needs by barter, and marrying the Indian girls, the French gained a remarkable power over the northwestern tribes, which caused them to consider whoever came from Canada their friend, even after the English government had supplanted the French in power. West of the lakes the transition from the French to the English rule created no disturbances, such as Pontiac's conspiracy which so completely disrupted the trade in the East.[5] Continuing the French policy and also their posts and voyageurs, the Scottish merchants of Montreal, organized in 1784 as the North West Company, pushed westward from Green Bay and southward from Lake Winnipeg. This advance was continued until the opening years of the next century. Although on nominally Spanish territory, the tribes on the upper Missouri were won from the Spanish traders at St. Louis by such severe cutting in prices that the latter could not compete. The posts of the North West Company on the Red River of the North became the resort for many of the western tribes.[6] The diverting of the trade of these natives, who would naturally have come down the Missouri where American traders could meet them and be benefited, was noticed by President Jefferson, who, on January 18, 1803, wrote to Congress: "It is, however, understood, that the country on that river is inhabited by numerous tribes, who furnish great supplies of furs and peltry to the trade of another nation, carried on in a high latitude, through an infinite number of portages and lakes, shut up by ice through a long season." In this same message was included a recommendation that a small expedition be sent up to confer with the tribes with respect to the admission of American traders.[7]
