What happened

What happened

On June 16, 1820, Lewis Cass, acting as the United States commissioner, met the Chippewa at the Sault de St. Marie in the Territory of Michigan. The treaty they signed was short, and it concerned land beside the St. Marys River, which runs along the boundary with British Upper Canada.

The Chippewa ceded a tract that began at the Big Rock in the river. It ran down the middle of the river to the Little Rapid, then back from the river far enough "so as to include sixteen square miles of land." In exchange, the Chippewa acknowledged receiving "a quantity of goods in full satisfaction." The treaty does not list the goods or give their value.

The treaty also contains a promise. The United States "will secure to the Indians a perpetual right of fishing at the falls of St. Mary's," along with a place of encampment on the ceded tract, near the fishing ground. That camp could not interfere with the defenses of any military work or with private rights.

The treaty took effect once the President and Senate ratified it, and the Statutes at Large record a proclamation on March 2, 1821. The treaty text does not say what happened to the fishing right afterward.
