All nations of the globe have migrated from earlier into more recent seats, but with many of them these migrations took place in epochs so far distant that they have lost all recollections of them. These latter we call autochthonic; the Kalapuya of Willámet Valley, Oregon, and the Washo around Carson, Nevada, who claim to have originated from bulrushes in the vicinity, belong to these. All tribes of the Maskoki stock possess migration legends, and so do the Dakota and Iroquois. Their migration legends are intermingled with myths and mythic ideas; nevertheless, they prove that the migrations took place in comparatively recent times, and that these accounts are not pure astronomical or other fictions.
