JEANCON] EXCAVATIONS IN. THE CHAMA VALLEY 9 
we judged that for some reason the round room was built at a later 
period than the remaining part of theruin. The oblong room below 
it is not complete; the south wall is gone and only partial traces of 
the west wall remain. The east wall runs out into the plaza for a 
distance of 1 m. and is below the wall of the round room. The walls 
of the oblong room are of the same type of construction as is found 
in all parts of the ruin. The walls of the round room are built almost 
entirely of bowlders from the river bottom. They were laid up in 
adobe mortar and plastered over with the same material. There are 
two well-defined floor levels, that of the oblong room being 485 mm. 
below the other. Both floors were made in the same way. In the 
east wall of the round room, where the wall was carried down to the 
level of the lower room, is a small doorway built level with the ground 
outside, similar to the openings found in the modern kiva of today. 
The old wall of the oblong room was torn down so that the doorway 
in the outer wall could be utilized. The distance between the walls 
is 585 mm. In the ground which was used to bring the level of the 
oblong room to that of the round room were found only the sherds 
of biscuit and incised ware. On the round room level were no sherds, 
but a few pieces of flaked stone, some pieces of bone, of no definite 
form, and a piece of deer antler. All of these articles are of the same 
type and character as those found elsewhere in the ruin. 
As to the function of the room, no opinion has been formed, as 
there is not enough material to indicate its character. Whether it 
was a watchtower (judging from its prominent position overlooking 
the whole valley in all directions) or whether it was a kiva I am not 
prepared to say. 
The walls of the round room are so far gone that it is impossible 
to even estimate the height of the room. It is along the north wall 
in which this room occurs that practically all of the rooms are washed 
out, and the amount of débris which formed the mound of the round 
room would hardly be enough to give a room over 1 m. in height. 
Possibly there were adobe walls placed above the stone walls to give 
the required height, but no trace of these remains. 
KITCHEN OR COOKING ROOM 
In room 1, location 6, were several interesting fireplaces. (PI. 4.) 
In about the middle of the west wall was a fireplace 457 mm. long 
by 231 mm. wide. It was well plastered and raised 5 cm. above the 
floor. Alongside of this was a semicircular plastered place, 350 mm. 
wide and 86 mm. deep, level with the floor. In this were found the 
remains of a cooking pot. In the southeast corner of the same room 
was a large adobe plate, 475 mm. by 401 mm., set 51 mm. above the 
floor, with a binding wall on the north and south. This plate was 
covered with a thick, hard coat of floor composite and was very greasy.
