The earliest accounts of the Minnesota river are connected with the name of Le Sueur. There is no account of his explo rations published by himself.- From Charlevoix and La Harpe may be made out a fragmentary account of his travels. The following notes are derived from a perusal of such early publi cations as are accessible in the libraries of this city and St. Paul together with the publications of the Minnesota Historical Society. The di~covery of the reputed copper mine on the Blue Earth must have been made between 1693 and 1695. He received a commission in 1697 from the government of France to work it, and was furnished with an outfit and means for defence against the Indians.
