mains of what appears to have been a circular room, perhaps 8 or 10 
feet in diameter, though it is too much broken down to determine this 
accurately. Only a small portion of the south wall can be definitely 
traced. On the south slope of the mesa are indications of walls, too 
vaguely defined to admit of the determination of their direction. Similar 
vestiges of masonry are found on the north and west, but not extend- 
ing to as great a distance from the knoll as those on the south.

In that portion of the ruin which lies on top of the knoll, the walls so 
far as traced conform to the shape of the site. The ground plan of the 
buildings that onee occupied the slopes can not be traced, and it is im- 
possible to determine whether its walls were carried through continu- 
ously. 
The masonry exhibited in the few surviving fragments of wall is of 
unusually good quality, resembling somewhat that of the Fire House, 
Fig. 7, and other ruins of that class. The stones are of medium size, 
not dressed, and are rather rougher and less flat than is usual, but the 
wall has a good finish. The stone, however, is of poor quality. Most 
of the débris about the ruin consists of small stone fragments and sand, 
comparatively few stones of the size used in the walls being seen. The 
material evidently came from the immediate vicinity of the ruin. 
Pottery fragments were quite abundant about this ruin, most of the 
ware represented being of exceptional quality and belonging to the 
older types; red ware with black lines and black and white ware were 
especially abundant.
