The approach of the Centennial Anniversary of the Treaty of Greenville, and the want of a convenient, authen tic account of this important bit of local and national history, explain, in part, the appearance of this work. In order to give a clear and comprehensive idea of the significance of this event, a sketch of the previous history of the territory affected thereby is incorporated. The quotations, except where noted, are from the American State Papers, Vol. I, of Indian Affairs.
