It was the desire of the government to put an end to the ancient warfare between the two great tribes of Minnesota Indians. Pike in 1806 had induced some of their chiefs to smoke the calumet. In 1820 Governor Cass repeated the operation with the result of burning much good tobacco. Agent Taliaferro conceived a plan for keeping the peace between the Sioux and the Chippeways, which was to survey and stake out a partition line between their countries. In 1824, by permission of President Monroe, he took a delegation of Sioux, Chippeways, and Menominees to Washington, where an arrangement was made for a “grand convocation” of all the northwestern nations, to be held in the summer of 1825 at Prairie du Chien. That convocation was held, with many spectacular incidents, and a variety of adjustments were consummated. In particular it was agreed between the Sioux and Chippeway nations that their lands should be separated by a line to be drawn and marked by the white man’s science. That line, when tardily staked out ten years later, started from a point in the Red River of the North near Georgetown, passed east of Fergus Falls and west of Alexandria, crossed the Mississippi between St. Cloud and Sauk Rapids, and went on in a general southeast direction to the St. Croix, which it struck not far from Marine. The savages paid little respect to this air line, but went on with their accustomed raids. Within a year there was a bloody encounter in sight of the agent’s office. A single example of these savage frays may be given to illustrate their recurrence in series. In April, 1838, a party of Sioux hunting in the valley of the Chippeway River (of Minnesota) left a party of three lodges in camp near Benson, Swift County. Hole-in-the-day, the Chippeway chief from Gull River, with nine followers, came upon this camp, and professing himself peaceable was hospitably treated. In the night following he and his men rose silently, and upon a given signal shot eleven of the Sioux to death. One woman and a wounded boy escaped. In August of the same year Hole-in-the-day, with a small party, was at Fort Snelling. His arrival becoming known to neighboring Sioux, two or three relatives of the victims of the April slaughter waylaid him near the Baker trading-house, and opened fire. Hole-in-the-day escaped, but the warrior with whom he had changed clothes was killed.
