The culture of the Pueblos, both ancient and modern, bears every mark of local and independent growth. A knowledge of metals, other than to a limited extent for ornament, is nowhere evident. Tillage of the fields in a rude manner was the main source of the food supply. Pottery of fine temper and in symmetrical forms was manufactured by the women. That they had any other domestic animal than a fowl, and sometimes a dog, has not been shown. Mats and clothing were woven of the fibres of bark and grass, and the culture of cotton was at one time common, especially among the Moquis and Pimas. The arts of weaving feathers and working shells into decorative objects are not yet lost. Apart from the development of the art of architecture, there was little in the culture of the Pueblo tribes to lift them above the level of the Algonkins. The acequias, or irrigation trenches, about which much has been written, were a necessity of their climate, and were in use among their southern neighbors in Sonora, and the Navajos. LINGUISTIC STOCKS OF THE PUEBLOS. KERA STOCK. | Pueblos of Kera or Queres, Cochiti, Laguna, Acoma, | Silla, etc., on the upper Rio Grande, Jemez and San | Juan rivers. TEHUA STOCK. | _Jemez_, on the Jemez river. | _Piros_, on Rio Grande and in Chihuahua. | _Tanos_, near Albuquerque, New Mexico. | _Taos_, at Taos Pueblo. | _Tehuas_, at Tesuque and neighboring Pueblos. ZUÑI STOCK. | At Zuñi Pueblo. III. THE CENTRAL GROUP. 1. THE UTO-AZTECAN TRIBES. Of all the stocks on the North American Continent, that which I call the _Uto-Aztecan_ merits the closest study, on account of its wide extension and the high development of some of its members. Tribes speaking its dialects were found from the Isthmus of Panama to the banks of the Columbia River, and from the coast of the Pacific to the Gulf of Mexico. The relationship of these numerous bands is unquestionable, although many of them have freely adopted words from other stocks. This, however, will not surprise us if we recall that most of the Aryac languages of the old world owe about one third of their radicals to non-Aryac sources.
