Even the French in Canada were animated in their explorations by the dream of a North-West Passage. The name Lachine at the rapids above Montreal is the memorial of La Salle's hope that the Western Sea was to be reached along this channel. The Lake Superior region seems to have been neglected for twenty years after Radisson and Groseilliers had visited Lake Nepigon, or Lake Assiniboines, as they called it.
But the intention of going inland from Lake Superior was not lost sight of by the French explorers, for on a map (Parl. Lib. Ottawa) of date 1680, is the inscription in French marking the Kaministiquia or Pigeon River, "By this river they go to the Assinepoulacs, for 150 leagues toward the north-west, where there are plenty of beavers."
The stirring events which we have described between 1682 and 1684, when Radisson deserted from the Hudson's Bay Company and founded for the French King Fort Bourbon on the Bay, were accompanied by a new movement toward Lake Superior, having the purpose of turning the stream of trade from Hudson Bay southward to Lake Superior.
At this time Governor De La Barre writes from Canada that the English at Hudson Bay had that year attracted to them many of the northern Indians, who were in the habit of coming to Montreal, and that he had despatched thither Sieur Duluth, who had great influence over the western Indians. Greysolon Duluth was one of the most daring spirits in the service of France in Canada. Duluth writes (1684) to the Governor from Lake Nepigon, where he had erected a fort, seemingly near the spot where Radisson and Groseilliers had wintered.
Duluth says in his ardent manner: "It remains for me, sir, to assure you that all the savages of the north have great confidence in me, and that enables me to promise you that before the lapse of two years not a single savage will visit the English at Hudson Bay. This they have all promised me, and have bound themselves thereto, by the presents I have given, or caused to be given them. The Klistinos, Assinepoulacs, &c., have promised to come to my fort.... Finally, sir, I wish to lose my life if I do not absolutely prevent the savages from visiting the English."
Duluth seems for several years to have carried on trade with the Indians north and west of Lake Nepigon, and no doubt prevented many of them from going to Hudson Bay. But he was not well supported by the Governor, being poorly supplied with goods, and for a time the prosecution of trade by the French in the Lake Superior region declined. The intense interest created by D'Iberville in his victorious raids on Hudson Bay no doubt tended to divert the attention of the French explorers from the trade with the interior. The Treaties of Ryswick and Utrecht changed the whole state of affairs for the French King, and deprived by the latter of these treaties of any hold on the Bay, the French in Canada began to turn their attention to their deserted station on Lake Superior.
