The principal members of this stock are the Utes, Shoshonees and Comanches in the north, various tribes in Sonora, Chihuahua, Sinaloa and Durango in the center, and the Nahuas or Aztecs in the south. It is not to be understood that the one of these derived its idioms from the other, but rather that at some remote epoch all three were offshoots from some one ancestral stem. This was at a period before the grammatical forms of the tongue had reached full development, and probably when it was in a stage of isolation, with tendencies to suffix agglutination and incorporation. Since then the stages of growth which the several dialects have reached have been various. The one which far outstripped all others was the Nahuatl, which arrived at clear and harmonious sounds, fixed forms, and even some recognizable traces of inflection, though always retaining its incorporative character.
The establishment of the unity of this linguistic family we owe to the admirable labors of Joh. Carl Ed. Buschmann, who devoted years of patient investigation to examining the traces of the Nahuatl, or as he preferred to call it, the Aztec language, in Mexico and throughout the continent to the north. In spite of deficient materials, his sharp-sighted acumen discovered the relationship of the chief tongues of the group, and later investigations have amply confirmed his conclusions.[133]
Long before his day, however, the Spanish missionaries to the tribes of Sonora and Sinaloa had recognized their kinship to the Aztecs, and Father Ribas, in his history of the missions established by the Jesuits in Mexico, published in 1645, stated that the root-words and much of the grammar of all these dialects was substantially the same as those of the Nahuatl.[134]
It is without doubt the most numerous stock now surviving. According to the census figures of the governments of the United States and Mexico for 1880, the numbers were as follows:[135]
| Shoshonian group, including Pimas in U. S. | 26,200 |
| Sonoran group in Mexican Territory | 84,000 |
| Aztecan group | 1,626,000 |
a. The Ute or Shoshonian Branch.
The northern, or Ute branch, which I so call from its most prominent member, includes the Shoshonees, Utes and Comanches, with their numerous sub-tribes and affiliated bands. They occupied at the beginning of this century an immense area, now included in south-eastern Oregon, Wyoming, Montana, Idaho, Nevada, parts of California, New Mexico and Arizona, northern and western Texas, and the states of Durango and Chihuahua in Mexico. Other names by which they are known in this area are Snakes, Bannocks, Moquis, etc. Everywhere their tongue is unmistakably the same. “Any one speaking the Shoshonee language may travel without difficulty among the wild tribes from Durango, in Mexico, to the banks of the Columbia River.”[136] Their war parties scoured the country from the Black Hills of Dakota far into the interior of Mexico.
So far as can be ascertained, the course of migration of this group, like that of the whole stock, has been in a general southerly direction. The Comanche traditions state that about two hundred winters ago they lived as one people with the Shoshonees somewhere to the north of the head-waters of the Arkansas River.[137] This is borne out by similar traditions among the northern Shoshonees.[138] That very careful student, Mr. George Gibbs, from a review of all the indications, reached the conclusion that the whole group came originally from the east of the Rocky Mountain chain, and that the home of its ancestral horde was somewhere between these mountains and the Great Lakes.[139] This is the opinion I have also reached from an independent study of the subject, and I believe it is as near as we can get to the birth-place of this important stock.
This stock presents the extreme of both linguistic and physical development. No tongue on the continent was more cultured than the Nahuatl, and so were those who spoke it. The wretched root-digging Utes, on the other hand, present the lowest type of skulls anywhere found in America.[140] The explanation is easy. It was owing to their lack of nutrition. Living on the arid plains of the interior, little better than deserts, they had for generations been half starved. They were not agricultural, but lived along the streams, catching fish, and making a poor bread from the seeds of the wild sun-flower and the chenopodium. Their houses were brush huts, or lodges of dressed buffalo skins; and where the winters were cold, they dug holes in the ground in which they huddled in indescribable filth.
