[4] The report of Louis Antoine Bougainville, written in 1757 and based on the reports of Canadian officials, shows the extent of French commerce at the close of the period of French control. At Green Bay (La Baye) trade was carried on with the Folles-Avoines, Sacs, Foxes, Sioux, and other tribes, the annual output being from five to six hundred packages of furs. In the North, extending westward along what is now the international boundary to the Lake of the Woods and then along the lakes and rivers of the Lake Winnipeg system, was the territory of the post known as "The Sea of the West". This included seven forts and produced a yearly supply of from three to four hundred packages. "These regions are everywhere vast prairies; this is the route to take for the upper Missouri."--_Wisconsin Historical Collections_, Vol. XVIII, pp. 167-195. A picturesque account of the life of the French traders is given in Neill's _The History of Minnesota_ (Fourth Edition), pp. 115-119.

In 1792, Peter Grant built a trading house on the site of St. Vincent, Minnesota, on the east bank of the Red River, and in 1800-1801 the fort of Pembina was erected by the great traveller, Alexander Henry, the younger.--_South Dakota Historical Collections_, Vol. I, p. 138.

Traders of the Hudson's Bay Company also frequented the spot. Sergeant John Ordway records in his journal for December 1, 1804, that "a Scotsman who is tradeing at the Mandens came to visit us. he belonged to the hudson bay company.... he brought over Tobacco Beeds & other kinds of Goods. & traded with the Mandens for their furs & buffalow Robes. they bring Some Guns to trade for horses &. C. this hudsons bay comp^y lay Garrisoned near the N. W. Comp^y.... Eight or 10 days travel by land a North course from this."--_Wisconsin Historical Collections_, Vol. XXII, p. 169.
