Not only were the external walls of these old villages of the plains semicircular, as though built in conformity with the curved rock walls of the hollows in the cliffs, but they were continuous. That is, in all the rounded town ruins, except those which seem to have been reconstructed in more recent times, the outer walls were built first as great semicircular inclosures, hollow artificial cliffs, so to say, and afterward the house walls were built up against them inside, not into them, as they would have been had these outer and the inner walls been built up together. Moreover, not only were the ground plans of these towns of the plains semicircular, as though built in conformity with the curved rock walls of hollows in the cliffs in ancestral fashion, but the storerooms were also still tucked away in the little flaring spaces next to these now outer and surrounding walls, instead of being placed near the more convenient entrances fronting the courts. The huts or sheds for the turkeys, too, were placed not in the inclosures of the courts, but against and outside of these external walls of the villages; and while many of the dead were buried, as in the cliff houses, under the floors of the lowermost rooms, others of them, almost always men, and notably victims of war or accident, were still buried out beyond even the turkey huts. So both the turkey huts and some of the graves of these round villages retained the same positions relative to one another and to the "rearward" of the dwellings that had very naturally been given them in the cliff villages; for in these, being behind the houses and in the rear of the caves, they occupied the most protected areas; while in the round villages, being behind the houses, they were thrown quite outside of the villages, hence occupied the most exposed positions, which latter fact would appear inexplicable save by considering it as a survival of cliff-town usage. The kivas, or assembly rooms of the round villages, were placed generally in front of the houses facing the courts, as of old they had been built in the mouths of the caverns, also in front of the houses facing the canyons. Moreover, they were, although no longer in the way, wholly or in part subterranean, that is, sunk to the level of the court or plaza, as in the cliff towns they had been built (except where crowding rendered it necessary to make them two-storied, as in some cases) up the front slopes only to the height of the general cave floor or of the lowermost house foundations. Finally, there were no doorways in the lower stories of the rounded villages, the roofs of which were reached by ladders; but in the upper stories there were passages, some of which, although here no longer so needfully small, were still economically fashioned as of old--wide at the top, narrow at the base, like the T-shape granary avenues of the cliff ruins.
