Definitions
(Ethnol.) , the tribe, or tribes, of North American aborigines who built, in former times, extensive mounds of earth, esp. in the valleys of the Mississippi and Ohio Rivers. Formerly they were supposed to have preceded the Indians, but later investigations go to show that they were, in general, identical with the tribes that occupied the country when discovered by Europeans.
