lower edge of a roughly square opening a foot across, cut out from the
block itself and inclined slightly downward toward the exterior. It was
plastered and smoothly finished. This opening corresponds to the one in
the middle room already described. This filling block, with the orifice
under discussion, is shown in figure 330, and in detail in plate LVII.

The lower doorway, shown in figure 330, is much broken out, and although
now but 2 feet 11/2 inches wide at its narrowest part, no trace of the
original surface remains on the northern side. The opening was 4 feet 61/2
inches high and probably less than 2 feet wide, with vertical sides.

In the western wall of the southern room there was but one opening. This
is about 9 inches square, finished smoothly, and occurs in the upper
room, about 6 feet 5 inches above the floor. It is shown in plate LVIII.
The doorway between this room and the western room was smoothly finished
and is in good order except the top, which is entirely gone. It was
covered with double lintels made of poles 2 to 4 inches in diameter, the
lower series about 3 inches above the top of the door. The opening was
originally filled in like that described above, leaving only 8 or 10
inches of the upper part open. The lower part of the block was pierced
by a square hole, like that in the western room, but this has weathered
or been broken out and the block has slipped down, so that now its top
is 1 foot 51/2 inches below what was formerly the top of the opening. The
top of the filling block is still smooth and finished and shows across
its entire width a series of prints probably of flat sticks about an
inch and a half wide, though, possibly these are marks of some finishing
tool. The marks run north and south.

The opening below the one just described was so much filled up at the
time of examination that none of its features could be determined,
except that it was bridged by two tiers of sticks of the usual size as
lintels. The subsequent excavation before referred to, however,
apparently disclosed an opening similar to the one described, and, like
it, filled nearly to the top with a large block.

A little west of the middle of the northern wall there are three niches,
arranged side by side and about 61/2 feet above the first roof beams. The
niches are 10 inches high, a foot wide, and about a foot deep, and are
about 8 inches apart. They are smoothly finished and plastered, but were
roughly made.
