... a circular room still in a fair state of preservation. The wall that lies nearest the precipice is for the most part in ruins; the rest of the room is well preserved. After about half a meter of dust and rubbish had been removed, we were able to ascertain that the walls formed a cylinder 4.3 meters in diameter. The thickness of the wall is throughout considerable, and varies, the spaces between the points where the cylinder touches the walls of adjoining rooms[24] having been filled up with masonry. The height of the room is 2 meters. The roof has long since fallen in, and only one or two beams are left among the rubbish. To a height of 1.2 meters from the floor the wall is perfectly even and has the form of a cylinder, or rather of a truncate cone, as it leans slightly inward. The upper portion, on the other hand, is divided by six deep niches into the same number of pillars. The floor is of clay, hard, and perfectly even. Near the center is a round depression or hole, five-tenths of a meter deep and eight-tenths of a meter in diameter. This hole was entirely full of white ashes. It was undoubtedly the hearth. Between the hearth and the outer wall stands a narrow, curved wall, eight-tenths of a meter high. Behind this wall, in the same plane as the floor, a rectangular opening, 1 meter high and six-tenths of a meter broad, has been constructed in the outer wall. This opening forms the mouth of a narrow passage or tunnel of rectangular shape, which runs 1.8 meters in a horizontal direction and then goes straight upward, out into the open air. The tunnel lies under one of the six niches, which is somewhat deeper than the others. The walls are built of carefully hewn blocks of sandstone, the inner surface being perfectly smooth and lined with a thin, yellowish plaster. On closer examination of this plaster it is found to consist of several thin layers, each of them black with soot. The plaster has evidently been repeatedly restored as the walls became blackened with smoke. A few smaller niches and holes in the walls, irregularly scattered here and there, have presumably served as places of deposit for different articles; a bundle of pieces of hide, tied with a string, was found in one of them. The lower part of the wall, to a height of four-tenths of a meter, is painted dark red around the whole room. This red paint projects upward in triangular points, arranged in threes, and above them is a row of small round dots of red.... Circular rooms, built and arranged on exactly the same plan as that described above, reappear with exceedingly slight variations in size and structure in every cliff dwelling except the very smallest ones.... The number of estufas [kivas] varies in proportion to the size of the buildings and the number of rooms, ... [The ruin described contained two kivas.] ... The description of the first
