When the early settlers began to pioneer the unbroken forests of North America, they considered the various Indian tribes to be the true Aborigines of this continent. But long before the red man, even long before the growth of the present forests, there lived an ancient race, whose origin and fate are surrounded with impenetrable darkness. The remains of their habitations, temples and tombs, are the only voices that tell us of their existence. Over broad areas, in the most fertile valleys, and along the numerous tributaries of the great rivers of the central and western portions of the United States, are to be found these wonderful remains, of the existence and origin of which, even the oldest red man could give no history.
