Frontenac was not only in full sympathy with La Salle, but with other enterprising adventurers, and there is but little doubt that he shared the profits of the fur-traders. About the time that La Salle was improving Fort Frontenac as a trading-post, Raudin,[491] the engineer who had laid out the plan of that fort, was sent by Frontenac with presents to the Ojibways and Sioux, at the extremity of Lake Superior.[492] A nephew of Patron, named Daniel Greysolon du Lhut,[493] and who had made two voyages from France before 1674, had then entered the army as squire of Marquis de Lassay, was in the campaign of Franche-Comté and at Seneffe, having now returned to Quebec was permitted to go on a voyage of discovery in the then unknown region where dwelt the Sioux and Assineboines. On the 1st of September, 1678, with three Indians and three Frenchmen, Du Lhut left Montreal for Lake Superior, and wintered at some point on the shore of, or in the vicinity of, Lake Huron. On the 5th of April, 1679, he was in the woods, three leagues from Sault Ste. Marie, when he wrote in the third person to Governor Frontenac: “He will not stir from the Nadoussioux until further orders; and peace being concluded he will set up the King’s arms, lest the English and other Europeans settled toward California take possession of the country.”[494] On the 2d of July, 1679, Du Lhut planted the arms of France beyond Lake Superior, among the Isanti Sioux,[495] who dwelt at Mille Lacs, in what is now the State of Minnesota, and then visited the Songaskitons (Sissetons) and Houetbatons, bands of the Sioux, whose villages were one hundred and twenty leagues beyond. Entering by way of the St. Louis River, it would be easy, by a slight portage, to reach the Sioux village, which was at that time on the shores of the Sandy Lake of the Upper Mississippi.
