Mr. John H. Becker, of Berlin, in an able paper addressed to the Congrès des Américainistes at Luxembourg (_Compte Rendu de la Seconde Session_, tom. i, pp. 325–50), after offering plausible arguments for the identification of Tulan Zuiva of the Quichés, Hue hue Tlapalan of the Toltecs, Amaquemecan of the Chichimecs, and Oztotlan of the Aztecs, with the region of the upper Rio Grande del Norte and Rio Colorado—the land of the ravines, of grottoes, and of cañons—attempts to trace the Toltec migration as given by Ixtlilxochitl. His interesting solution of the difficult problem is as follows: “The Toltecs driven out of Hue hue Tlapalan by civil wars (towards the end of the fourth century of our era?) move in a westerly direction sixty leagues to Tlapalanconco (northern Sinaloa and Sonora on the Rio Yaqui, where distinct traces of the Nahua language exist?); thence, after eleven years, they go to Hueyxalan, seventy leagues distant (perhaps the northern part of Durango, where the Tepehuana language shows strong Nahua affinities); thence to Xalisco on the coast, one hundred leagues distant; thence to Chimalhuacan Atenco on the coast opposite some islands, one hundred leagues (opposite the islands in the southern end of the Gulf of California)? In that case they did undoubtedly suffer a reverse in Xalisco (where they touched upon the more thickly populated and civilized country, and by which they were forced to retire); thence eastward eighty leagues to Toxpan (in the neighborhood of the Laguna de Tlahuila and on the upper Sabina River). In that country there is even now a tribe of Tochos, and the Tarahumara language there spoken, shows distinct affinities to the Nahua tongue; thence eastward one hundred leagues to Quahuitzlan Anahuac, on the coast with inlets—the coast-land of the state of Tamaulipas, on the Gulf of Mexico? About this locality there can scarcely be a doubt, since this eastern coast country and the eastern plateau bore the general name Quetzalapan or Huitzilapan, until the Nahuas took possession of them, when the plateau was designated as _Huitznahuac_, and the name above given would be the natural one to apply to the coast, since while _nahuac_ (_an_) means simply the Nahualand, _Anahuac_ (_an_) means the ‘Nahua land on the water,’ while Quahuitzlan is the old name retained in order to distinguish this Anahuac on the Gulf coast from the Anahuac around the Mexican lakes. Here they ‘suffered great hardships,’ and finally went westward eighty leagues to Zacatlan (the northern part of the State of Zacatecas?); from there eighty leagues to Totzapan, probably again in the neighborhood of Toxpan before mentioned (where the Tusanes are located even to-day); thence one hundred and forty leagues to Tepetla (the extraordinary distance shows that at last they gained a decisive victory, and broke through the frontier of the more civilized country which they had hitherto felt). Tepetla, mountainland, must consequently
