A remarkable fact about the American Indians, and one which is astanding puzzle to ethnologists, is the wide range of colour andcomplexion to be found among them. From the white tint of the Menominee,Dakota, Mandan and Zuni tribes, many of whom have auburn hair and blueeyes, to the almost negro blackness of the Karos of Kansas and the nowextinct tribes of California, the Indian races run through every shadeof red-brown, copper, olive, cinnamon, and bronze. (See Short's _NorthAmericans of Antiquity_, Winchell's _Pre-Adamites_, and Catlin's_Indians of North America_; see also _Atlantis_, by Ignatius Donnellywho has collected a great mass of evidence under this and other heads.)We shall see by and by how the diversity of complexion on the Americancontinent is accounted for by the original race-tints on the parentcontinent of Atlantis.
