Company’s post at Fond du Lac (of Superior) on the 6th of July. He ascended the St. Louis River and took the Savanna portage to Sandy Lake. With a reduced party he pushed up stream through Lake Winnebigoshish to that upper Red Cedar Lake which Pike had seen fourteen years before. Assured that this was the true source of the Mississippi, he ended his journey. Mr. Schoolcraft doubted, but he was too polite to differ openly with his chief. Captain Douglass on his map gave the lake the name “Cassina,” which, shorn of two superfluous syllables, has remained in use. Mr. Schoolcraft wrote a narrative of the expedition which is very pleasant reading. The return journey, beginning July 22, was down the Mississippi to Prairie du Chien and thence to Green Bay by the Fox-Wisconsin portage. At Fort Snelling the party were feasted with fresh vegetables from the post garden. At the Sioux agency, then on the Mendota side of the Minnesota, some chiefs of the Sioux and Chippeways were got together in council and a reluctant consent was obtained to cease from troubling one another. The high contracting parties were content to gratify the white man, but they understood the farcical nature of the convention. Governor Cass reported the cost of the expedition at $6156.40-1/4. It seems proper to interpolate here some account of the expedition conducted by Major Stephen H. Long of the topographical engineers of the army, in 1823, to the valleys of the Minnesota and Red rivers. Six years before, that officer had made an uneventful journey to St. Anthony’s Falls, of which he left a graphic and appreciative description. His party, escorted by a detail of soldiers, left Fort Snelling on July 9 with Joseph Renville as interpreter and guide. At Traverse des Sioux, Long abandoned his canoes and set out overland by the well-worn trail for Lake Traverse, where he was welcomed at the headquarters of the Columbia Fur Company. On August 2 Long reached Pembina, where he established a monument to mark a point astronomically determined in the international boundary. His instructions had been to strike east from Pembina and trace the boundary to the Lake of the Woods. This he found to be impracticable. Putting his people into bark canoes, he descended the Red River past Fort Garry to Lake Winnipeg, traversed the south arm of that water, and ascended the Winnipeg River to Rat Portage on the Lake of the Woods. The homeward journey by the old Dawson route to Lake Superior, along the north shore to the Sault Sainte Marie and thence by the lower lakes and the Erie Canal, was rapidly made without notable incident. Professor William H. Keating of the University of Pennsylvania, who was geologist of the expedition, published a narrative abounding in varied and interesting knowledge. It will ever remain indispensable to the historian of the period and region.
