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 of the opening. In this opening the supporting
lintel was formed of a number of poles 2 to 4 inches in diameter,
irregularly placed, sometimes two or three in vertical series with very
little filling between them. This construction has been characterized as
a Norman arch. The opening was originally 1 foot 11 inches at the top
and 4 feet 6 inches high. The bottom is 1½ inches wider than the top.

The upper opening in the western end of the southern wall is much like
that just described. A small fragment of masonry above the lintel
remains, and this is within a quarter of an inch of the top of the
opening. Above the opening there was a series of rough lintel poles, 3
to 5 inches in diameter, arranged in three tiers with 4 to 6 inches of
filling between them. Prints of these sticks are left in the wall and
show that some of them were quite crooked. Probably they were of
mesquite, obtained from the immediate vicinity. The edges of the
openings were finished with flat sticks, like those described, and its
bottom was 6 inches to a foot above the floor. The height of the opening
