Section _f f g g_:-- Lower story. 22 × 6 132 Second story. 22 × 5 110 Third story. 22 × 4 88 Fourth story. 22 × 3 66 -- 396 ---- Total number of rooms contained in building _B_ 517 These rooms are very nearly of equal size, the largest one being _III._ 2.85 m. × 4.78 m.--9 ft. × 16 ft.--on one side, and 3.71 m.--12 ft-on the other, with an entering angle; the smallest room adjoining to it measuring 2.25 m. × 2.70 m.--7 ft. × 9 ft. The entire structure, therefore, presents the appearance of a honeycomb, or rather of a bee-hive, and perfectly illustrates, among the lower degrees of culture of mankind, the prevailing principle of communism in living, which finds its parallel in the lower classes of animals. Tradition, historical relation, and analogy, tell us that this house was used as a dwelling,[105] and that consequently it was, to all intents and purposes, a communal house. The height of the various stories it is almost impossible to determine. I have measured walls which appeared to be perfect, and they gave me an average of 2.28 m.--7 ft. 6 in.--elevation. Should such be the rule, the western wall of the building, at its greatest height south, would have risen about 11 m.--36 ft. The northern appendix I have ignored in the above computation, because its whole appearance gives no ground for definitive statements. It seems really to be an annex, and in fact the whole building seems to have progressed, in its construction, from south to north, in point of date and time. The southern portion of the building--the one which appears to have been erected on a plane surface--was, in all probability, the one first built. The northern portions were added to it gradually as occasion required. This is further shown by the fact that in these northern sections, along the line _a, b, c_, parts of the third story wall are patched with regular adobe bricks, about half as large as those in the church, but still made by the same process.[106] The rest of the structure is exclusively composed of stone.
