ruin. The compass readings were made from an ordinary hand 
compass and are nearly enough correct to give a general idea of the 
orientation. 
Rooms 
A peculiar feature of the ruin is the size of the rooms. The largest 
is 5.76 by 2 m.; the smallest is 2.15 by 2m. Most of the rooms are 
about 3 to 3.5 m. long and 2 to 2.5 m. wide. Large rooms such as 
these are unusual on the Jemez Plateau and might be taken as an 
indication that the ruin is of a late pre-Spanish period. (PI. 3.) 
Only one room of any depth was found. Room 5, location 10, 
was 2.25 m. deep, 4.84 m. long, and 1.91 m. wide. The tops of the 
walls showed no marks of where the joists had been set in, so that 
it is reasonable to suppose that originally the room was higher. This 
would mean a good-sized room of 1.78 m. or more in depth. The 
size of this room corresponds pretty well with the older rooms in 
the modern pueblos. 
Rooms at the end of the row were usually smaller than at any 
other place, although in location 7 was found a very small one em- 
bodied in the main group. In some cases the uses to which the 
rooms were put were very clearly shown. A kitchen or cooking 
room—room 1, location 6—will be referred to later, as will also the 
Weaving room—room 2, location 6. Four rooms, which I judged 
were ceremonial rooms from the objects found in them, were in 
almost the same relative location in each row—on the east, north, 
west, and south sides of plaza No.1. They were not all on the same 
flocr level. Room 10, lccation 12 (east side), was a ground-floor 
room; room 2, location 9 (north side), was a second-story room; 
room 14, location 8 (west side), was a second-story room; room 14, 
lecation 7 (south side), was a ground-floor room. None of these 
had a bench or other distinguishing feature such as occurs in a kiva or 
kisu, and I only judge their use from the ceremonial objects which 
were found in them. 
Room 23, location 3, in the second story, was unquestionably a 
storage room of some sort, for in this room we found a vast number 
of broken bewls, storage jars, and other pottery, which indicated, 
from the manner in which the fragments lay, that they had been 
packed one inside of the other. 
ROUND ROOM 
At the northeast corner of plaza No. 2 is one of the most inter- 
esting features of the whole ruin. This is a round room built over 
an oblong one. (Pl. 4.) The north line of plaza No. 2 projects 
beyond the east line, forming a sort of guard wall for the north- 
ern entrance to plaza No. 1. Ata point where the two lines meet 
is the round room. From evidences determined by the excavations,
