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.
