was at the highest point eighty feet above the floor. The houses were
arranged in an arc of a circle so large as hardly to deviate from a
straight line. The front row seems to have been of but one story,
while the adjoining row back of it had two stories. The roof of
the houses at no place reached the roof of the cave. Each room was
about twelve feet square, and the walls, which showed no evidence
of blocks or bricks, varied in thickness from fifteen inches at the
base to seven inches at the top of the highest. At some places large
stones were built into the walls; in another wall wooden posts and
horizontal sticks or laths were found. The surface of the walls,
which were protected against the weather, was smooth and even, and
the interior walls showed seven or eight coatings of plaster. The
floors, where they could be examined, were smoothly cemented and so
hard as to effectively resist the spade. The pine poles which formed
the roof were smooth, but not squared; they were three to four inches
in diameter; and some of them were twenty-four feet long. According
to all appearances, they had been hewn with a blunt instrument, as
they were more hacked than cut. Many of them were nicely rounded
off at the ends, and several inches from the ends a groove was cut
all around the pole.

In the centre of the back rooms of the ground floor there was
usually a pine pole, about ten inches in diameter, set up like a
rude pillar. Resting on this and the side walls of the rooms in a
slight curve was a similar pole, also rounded, and running parallel
to the front of the houses; and crossing it from the front to the
rear walls were laid similar poles or rafters about four inches in
diameter. The ends of these were set directly into the walls, and
covering them was a roofing of mud, some three inches thick, hard,
and on the upper surface smooth. The second story, where it had not
