ed in the stones, another wall was piled up on it as
straight as possible. In this manner it became possible to add each
cell separately.

There are several doors visible in _A_, as marked on the ground-plan.
Those in the eastern and western wings open from east to west, those in
the northern wing from north to south; therefore transversely to the
length of each structure. But I have also seen longitudinal walls
without passages. The tops of the doors are all gone; the rest is
everywhere similar to the sample found in _B_, and already figured. In
some cases even the sills are gone. Windows I could not find, nor
trap-doors or ladders; there was no trace of steps, and, unfortunately,
no clew to any chimney or vent. Of furniture I secured pieces of new
hearth-stones; of other articles, broken "metates," part of a fine maul
of stone, flint chips, celts, stone skin-scrapers, and, of course,
painted pottery and obsidian. But not one specimen is entire; every
striking implement, etc., has been carried off by amateurs, of whose
presence besides broken beer bottles, with the inscription
"Anheuser-Busch Brewing Co., St. Louis, Mo.," give occasional notice.

Room _I_, in the S.W. corner of the north wing is very well preserved:
so well, indeed, that it is nearly certain that there was no entrance to
it from above. On the contrary, the entrance appears to have been from
the front, as shown in Pl. VIII., where this room stands in full view.
It is perfectly plain inside; eight posts of wood, round, and stripped
of all bark, support the ceiling and roof, whose composition I have
elsewhere described. These posts (which are also shown in Pl. VIII.) are
so distributed as to have one in each corner, and two between, on each
longer side of the room. In the S.E. quarter of the ceiling the
splinters covering the rafters or poles are removed, and fresh straw (or
rather very well preserved) protrudes, as having formed a layer with the
brush. I was at first inclined to take it for wheat-straw, but other
parties insisted that it was mountain grass. For the latter it appears
to be very long, and it has a marked head. I have not, as yet, seen any
wheat-plants grown at these elevations.[124]

Otherwise this chamber appears nearly perfect. In the middle of the
north wall a hole is knocked out, but the two coats of plaster (dark and
white) are almost everywhere preserved. Great interest attaches to this
apartment, from the fact that, according to S
