Our explorations during the field season of 1880 and 1881 were restricted to the Pueblo tribes located along the Rio Grande and its tributaries in New Mexico. The chief object in view was to secure as soon as possible all the ethnological and archaeological data obtainable before it should be lost to science by the influx of civilized population which is being rapidly thrown into this region by the extension of railroads into and through it. Not only are the architectural remains being rapidly destroyed and archaeological specimens collected and carried away by travelers, excursionists, and curiosity hunters, but the ancient habits and customs of these tribes are rapidly giving way and falling into disuse before the influence of eastern civilization. Our party, consisting, besides myself, of Mr. Galbraith, archaeologist, Mr. Morancy, assistant, and Mr. J. K. Hillers, photographer, proceeded to Santa Fe, N. Mex., where an outfit was secured for the season's work. From here we proceeded to Taos, one of the most extensive pueblos in the Rio Grande region. This village is situated on the Rio Taos a few miles from the Rio Grande, and just under the shadow of the Taos Mountains. It comprises two large sections, one on each side of the Rio Taos. These are compactly built and each six stories high. The industrial pursuits of these Indians are principally pastoral and agricultural, they having a good market for their products in the Mexican village of Fernandez de Taos, containing a population of about 4,000 Mexicans and eastern people. The party spent several days here making investigations and collections. The collection made was small but quite varied and novel, though few of the articles obtained were of their own manufacture. Quite a number of stone implements were secured, among which were some stone knives, pipes, a number of rude stone axes and hammers, arrow smoothers, &c. The pottery obtained here is chiefly of the common type and resembles that from San Juan, from whence in all probability it was received by exchange and barter. Earthenware, so far as I can learn, is not now made in Taos, except by a few families where a Taos Indian has married a woman from San Juan or some other tribe where the manufacture of pottery is carried on. If this industry was ever, practiced by the Taos Indians it must have been at a remote period; in fact there seems to be no tradition of it now among them.
