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. x 4.78 m.--9 ft. x 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. x 2.70 m.--7 ft. x 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
