e eastern opening in the northern wall, opening into the east room, is
well preserved except the top, which is missing. It measured 4 feet 21/2
inches in height and 1 foot 11 inches wide at the bottom, the top being
nearly an inch narrower. It carried two tiers of lintels of medium size.

The gap in the southern wall of the southern room, shown in the plan,
though now open from the ground up, represents the location of two
doorways, one above the other. Remains of both of these can still be
seen on the ends of the walls. No measurements can be obtained. The
large fallen block near the southwestern corner of the room, which
undoubtedly slipped down from above, shows a finished surface at the
ground level inside, but above it no trace of an opening can be seen,
possibly because the ends of the walls above are much eroded.

The upper opening in the eastern wall of the eastern room was apparently
capped with a single lintel composed of five sticks 4 to 6 inches in
diameter laid level on the top of a course of masonry. The bottom of the
opening is filled either with washed-down material or with the remains
of a block such as that previously described. This opening is the most
irregular one in the building, the top being nearly 4 inches narrower
than the bottom, but the northern side of the opening is vertical, the
southern side only being inclined inward. The opening was 4 feet 11
inches high and 1 foot 81/2 inches wide at the bottom. The opening
immediately below that described, which was the ground floor entrance
from the east, is so much broken out that no evidence remains of its
size and character. There appears to have been only one row of lintel
poles.

The eastern opening in the southern wall of the northern room is well
preserved, the lintels having been torn out by relic hunters without
much destruction of the surrounding masonry. It was neatly finished, and
its bottom, was probably a little above the first roof level. The edges
of the openings were made straight with flat sticks, either used as
implements or incorporated into the structure, and forming almost
perfectly straight edges. Marks of the same method of construction or
finish are apparent in all the other openings, but the remains are not
so well preserved as in this instance. Possibly the immediate lintels of
openings were formed of thin flat sticks, as the lintel poles are often
some inches above the top o
