Es-sat's four handlike members and his long, sinuous tail permitted him to move with consummate ease whither he chose—a gigantic rat upon a mighty wall. As he progressed upon his way he avoided the cave mouths, passing either above or below those that lay in his path.
The outward appearance of these caves was similar. An opening from eight to as much as twenty feet long by eight high and four to six feet deep was cut into the chalklike rock of the cliff, in the back of this large opening, which formed what might be described as the front veranda of the home, was an opening about three feet wide and six feet high, evidently forming the doorway to the interior apartment or apartments. On either side of this doorway were smaller openings which it were easy to assume were windows through which light and air might find their way to the inhabitants.

From many of these smaller apertures small streams of water trickled down the escarpment, and the walls above others was blackened as by smoke.
