With the exception of one chamber in building A, I nowhere met anything like a roof. This one appears to be nothing else than a ceiling-floor, but of nearly 0.75 m.—2 ft. 6 in.—in thickness. It is, as [Pl. VIII.] shows, much covered by fallen stones, and its original height may have been increased by débris; but at all events it was thoroughly impermeable, and such as would be required in a climate[p. 60] where, indeed, it seldom rains, but "whenever it rains it pours."
There is a certain air of sameness cast over the entire structure which has strongly impressed me with the thought that not only was it used as a dwelling for a large number (as the reports, indeed, establish), but also that all its inhabitants lived on an equal footing,—as far as accommodations for living were concerned. There are no special quarters, no spacious halls. The few rooms of somewhat larger size are naturally explained by the mode of construction, adapting the house to the configuration of the rock, and not conversely as we do. It was, therefore, a large joint-tenement structure, harboring, perhaps, when fully occupied, several hundreds of families.
In regard to ingress and egress, not only have I found no doors in any fragments of exterior walls, but the many persons I have asked have always assured me that there had been none, that the house was entered by means of ladders, ascending to the top of each story in succession, and descending into the rooms also by ladders and through trap-doors in the roofs. They have also assured me that each room of each story communicated with the one above and below, also by means of trap-doors and ladders. It is quite certain that there are no staircases nor steps, and that consequently ladders were used, in the same manner as they are still used by the Indians of the pueblos of Zuñi, Moqui, Acoma, Taos, and others. Ingress and egress, therefore, must have taken place, not horizontally "in and out," but vertically "up and down." I have not been able to identify any one of the trap-doors referred to, but I should not be surprised to hear that they have been subsequently found in the north-west corner of each room. By referring to the diagram of the floor ([Pl. III.], Fig. 4), it will be seen that the rectangular spaces between the beams and overlying poles are almost everywhere large[p. 61] enough, if the superstructure of splinters (or brush) and clay is removed, to give passage to any man. The ladders themselves have completely disappeared.
On one and the same floor, I found in the side walls at a few places, the remains of low and narrow openings through which a man might pass in a stooping position and "sidling." Nowhere could I see the full height of these small doorways, so that I do not know whether there was a lintel, or whether they terminated in an open angle, like the doorways of Yucatan. I have seen openings showing the peculiar so-called "aboriginal arch" of Yucatan on a small scale, and I also have seen that an accidental "knocking-out" of one or two stones from the walls produced a hole or gap very similar in shape to the doorways at Uxmal and other pueblos of Southern Mexico, though of course on a small scale. It is self-evident that, the coincidence being accidental, I do not place any stress upon it in view of "tracing relationships." The coincidence is of ethnological, and not of ethnographical, value. As far as I could ascertain, they were certainly 1 m.—3 ft. 3 in.—high, whereas their average width may have been 0.45 m.—18 in. (Those I measured averaged between 0.42 m. and 0.48 m.—16 in. and 19 in.) Their appearance is shown in [Pl. II.], Fig. 5.
a is what might be termed a door-sill, a smooth oval stone, evidently from the drift, probably dioritic, at all events a dark-green hornblende rock. In the present instance one was not long enough to fill the gap left between the walls, and two were superposed. I saw no traces of wooden lintels or sills. These doorways appeared to be generally about 0.50 m.—20 in.—above the floor, but if we deduct 0.20 m.—8 in.—for the clay (measure having been taken from the timbers), 0.30 m.—12 in.—will remain as their approximate height over the chambers.[p. 62]
The few doors that I could observe are all in the longitudinal walls, and none of them in the transverse; that is, they all open from east to west. But not all the longitudinal partitions have doorways. It cannot, therefore, be admitted that every transverse row was occupied by one family, still less that the family apartments were arranged longitudinally. I rather suspect that this arrangement was vertical, or perhaps vertical and transverse. This surmise is given, however, for what it may be worth. Windows I could not find, although small apertures undoubtedly existed in all the outer walls, both for light and for air.
The chambers being all very much ruined, the lower ones filled with the stones and decayed ruins of the superposed stories,—of these stories themselves but part of the walls, denuded and often twisted, remaining,—I have not been able, with one single exception, to secure or even see any of what we would call the "furniture." Small fragments of grinding-stones (metates) are sparsely scattered over the entire ruins, otherwise the only object of daily use as articles of furniture met with by me has been a hearth, which I found or dug out in situ, in room I, and which, complete, forms part of the collections sent by me to Cambridge.
The place where this hearth was situated is marked on the diagram in room I. It stood on the floor against the north wall, and is composed of three plates of stone, originally ground and polished (as the specimen found in building A will show, which is a fragment only), and, judging from new fragments found, of diorite or other hornblende rock. There are three plates,—a basal one, 40 m.—16 in.—long and 20 m.—8 in.—wide, and two sides, placed vertically east and west of the base,—all three resting against the north wall of the room. [Pl. III.], Fig. 4, is a diagram of the room, the floor timbers, and the hearth.[p. 63]
The basal plate was covered with 0.10 m.—4 in.—of very white ashes, which I have also secured, and the rear of the hearth, which is formed by the original "first coat" of earth daubed over the wall, is thoroughly baked by the heat produced in front of it, as the samples sent will show.[111]
Of course, I looked at once for an opening where the smoke arising from the hearth, etc., could have escaped. I am sorry to say, however, that I utterly failed in finding anything like a chimney,—not only in B, but in all the other buildings. Still, in the ruined condition of the place, this is no proof of their non-existence.[112]
