The collection contains two thousand eight hundred and fifty-eight specimens. Although it consists very largely of vessels and other articles of pottery, yet it embraces almost every object necessary to illustrate the domestic life and art of the tribes from whom the largest number of the specimens were obtained. It includes, in addition to pottery, implements of war and hunting, articles used in domestic manufactures, articles of clothing and personal adornment, basketry, trappings for horses, images, toys, stone implements, musical instruments, and those used in games and religious ceremonies, woven fabrics, foods prepared and unprepared, paints for decorating pottery and other objects, earths of which their pottery is manufactured, mineral pigments, medicines, vegetable dyestuffs, &c. But the chief value of the collection is undoubtedly the great variety of vessels and other articles of pottery which it contains. In this respect it is perhaps the most complete that has been made from the pueblos. Quite a number of articles of this group may perhaps be properly classed as “ancient,” and were obtained more or less uninjured; but by far the larger portion are of modern manufacture. ARTICLES OF STONE. These consist of pestles and mortars for grinding pigments; circular mortars, in which certain articles of food are bruised or ground; _metates_, or stones used for grinding wheat and corn; axes, hatchets, celts, mauls, scrapers &c. The cutting, splitting, pounding, perforating, and scraping implements are generally derived from schists, basaltic, trachytic, and porphyritic rocks, and those for grinding and crushing foods are more or less composed of coarse lava and compact sandstones. Quite a number of the metate rubbing stones and a large number of the axes are composed of a very hard, heavy, and curiously mottled rock, a specimen of which was submitted to Dr. George W. Hawes, Curator of Mineralogy to the National Museum, for examination, and of which he says: “This rock, which was so extensively employed by the Pueblo Indians for the manufacture of various utensils, has proved to be composed largely of quartz, intermingled with which is a fine, fibrous, radiated substance, the optical properties of which demonstrate it to be fibrolite. In addition, the rock is filled with minute crystals of octahedral form which are composed of magnetite, and scattered through the rock are minute yellow crystals of rutile. The red coloration which these specimens possess is due to thin films of hematite. The rock is therefore fibrolite schist, and from a lithological standpoint it is very interesting. The fibrolite imparts the toughness to the rock, which, I should judge, would increase its value for the purposes to which the Indians applied it.”
