in the construction of the roof are well marked in the east and west 
walls of the second story. The outer face of the north wall is much 
eroded near the top, exhibiting no evidences of continuation into a 
third story. There was a low parapet rising slightly above the roof 
on the north, as well as on the east and west walls of the north room. 
Both lower and upper stories of the west room have smooth walls, 
but the exterior surface of the walls of the central room, above the 
line of the second floor, is rough, indicating that the western inclosure 
never had more than two stories. The east wall of the west room 
is slightly curved, while the west wall of the same room is straight. 
Rows of holes in the east wall, which formerly received the floor beams, 
are arranged somewhat irregularly. The inner faces of the walls of 
the south room are finely finished, particularly on the south side, 
although the wall itself is in places more broken than the north or 
west walls. The holes for beams in the south wall are less regular 
in arrangement than those in the north wall. 
A fragment of the east wall of the south room remained standing 
up to within a few years, when the repairs were made by contractors. 
At one time the south room was excavated far below its original 
floor, as indicated by the line of erosion on the surface of the north 
wall and a corresponding line on the opposite side walls. There were 
formerly two doors, one above the other, in the south wall, but the 
lintel between them has disappeared, the south wall remaining in the 
form of two very unsteady sections. The interior walls of the east 
room are finely finished, while the exterior surface of the east wall of 
the central room is very much eroded. The exterior surface of the 
east wall of the central section shows the effects of exposure to the 
weather, suggesting that there were but two stories to the eastern 
part. The north wall of the central rooms runs through the east 
wall, without bonding, suggesting later construction of the latter. A 
wide crack left in the east wall where the north wall joins is smoothly 
plastered over for part of its length, a condition which implies earlier 
construction. The inner walls of the central rooms are smooth; the 
marks of reeds, grasses, and rafters indicate the former existence of 
floors in this part of the building. The roughness of the plaster above 
the line of the floor of the second story indicates that there was once 
a low banquette about the room. The row of holes that accommodated 
the beams of the roof of the third story is not flush with the top of 
the wall but somewhat below it, indicating that the walls there were 
formerly continued into a low parapet.

The floors of the second and third stories served us ceilings of the 
first and second stories, respectively, and resemble those of the ordi- 
nary adobe houses of the Southwest. The beams were small cedar
