The process, from the evidences shown inside, of carving out the interior of the dwelling was by scraping grooves several inches deep and apart, and breaking out the intermediate portion; in this way the work progressed until the room reached the desired size. Inside of these rooms were found many little niches and excavated recesses used for storing household ornaments, the larger ones probably supplying the place of cupboards. Near the roofs of many of the caves are mortises, projecting from which, in many instances, were found the decayed ends of wooden beams or sleepers, which were probably used, as they are now in the modern Pueblo dwellings, as poles over which to hang blankets and clothing, or to dry meat. These dwellings were without fireplaces; but the evidences of fire were plainly visible at the side of each cave, and in none of those visited did we find any orifice for the egress of the smoke but the small doorway. On the outside or in front of these singular habitations are rows of holes mortised into the face of the cliffs about the doors. It is quite evident that these were for the insertion of beams of wood (for forming booths or shelters in the front), as ends of beams were found sticking there, which, in their sheltered position and in this dry climate, may have been preserved for centuries. Upon the top of the mesa of which these cliffs are the exposed sides we found the ruins of large circular buildings made of square stones 8 by 12 inches in size. The walls of some of these structures remain standing to the height of ten or twelve feet, and show that from four to five hundred people can find room within each inclosure. One of these buildings was rectangular and two were round structures. The latter were about 100 and 150 feet in diameter, the rectangular one about 300 feet square. Many small square rooms were constructed in the interior from large cut bricks of the tufa of which the bluffs are composed. These rooms all opened toward the center of the large inclosure, which has but one general doorway. From these ruins we secured great quantities of pottery, arrow and spear heads, knives, grinding-stones, arrow-smoothers, and many of the small flint adzes, which were undoubtedly used for making the blocks for the structures on the mesa and for excavating the cave dwellings. Among the debris in the dwellings are found corncobs and other evidences of the food used by the inhabitants. This certainly indicates that the people who occupied these singular dwellings were agricultural. The faces of some of the more prominent cliffs contained as many as three rows of chambers one above the other; the debris at the foot, sometimes 200 feet deep, covered up at least two rows of these chambers.
