Payne has made it abundantly clear to our mind that the original seat of the Nahuatlacâ (which included both Toltecs and Aztecs) was in British Columbia (see his "History of America," vol. ii. p. 373 et seq.). He thinks they there occupied a position southerly to that of the Athapascan stock, and were probably the first northern people to come into contact with tribes possessed of the maize plant. The knowledge of this staple, he infers, spread rapidly among the northern peoples, and induced them to hasten their southern colonisation, but it does not appear to us probable that this would be an inducement to a savage flesh-eating people averse to a life of agricultural labour. The whole question of pre-historic American migration, and of the gradual civilisation by maize of the peoples who came within its zone, is most admirably discussed in vol. xix. of "The History of North America," by W. J. Magee and Cyrus Thomas (Philadelphia, George Barrie and Sons), published March 1908. The knowledge contained in this work is the outcome of a lifetime's labour in the U.S. Bureau of Ethnology, and its learned authors have undoubtedly produced a monumental treatise which it will take many a generation of research to supersede, if, indeed, that is possible. NOTE 3. (PAGE 9) The authorities for the settlement of the Toltecs in Yucatan are the Tezcucan chronicler Ixtlilxochitl, and Torquemada, who both allege that the immigrants went to Campeachy and the south. NOTE 4. (PAGE 13) There appear to be grounds for believing that the parent deities Xpiyacoc and Xmucane are but derivations from Gucumatz, and represent the male and female attributes of that god. In the "Popol Vuh" they are spoken of as being "covered with green feathers," the usual description of Gucumatz; but it is, of course, possible that they may have received some of his attributes in the general jumble of myths which, we have attempted to show, exists in the first book. Gucumatz, it will be remembered, is Quetzalcohuatl in another form, and the latter is often represented in the papyri as having a woman sitting opposite to him. She does not, however, appear to be at all analogous to Messrs. Förstemann and Schellhas's "Goddess I," whom I take to represent the Mayan equivalent of Xmucane, and who wears on her head the knotted serpent, a reptile characteristic of Quetzalcohuatl. NOTE 5.
