tangular chamber. It was impossible to ascertain the form of this 
second room, as the writer was not permitted to approach the connect- 
{ ing doorway, which was closed 
with a slab of cottonwood. This 
chamber, used as a receptacle for 
religious paraphernalia, was said 
to connect with an upper room 
within the cluster of dwellings 
close by, but this could not be 
verified at the time of our visit. 
The plan indicates that such an 
adjoining chamber, if of average 
size, could easily extend partly 
under the dwellings on either 
the west or south side of the 
court. The rocky mesa summit 
is quite irregular in this vicinity, 
with rather an abrupt ascent to 
the passageway on the south as 
shown in Pl. xxi. Southeast 
from the kiva there is a large 
mass of rocks projecting above 
the general level, which has been 
incorporated into a cluster of 
dwelling rooms. Its character 
and relation to the architecture 
may be seen in Pl. xx. So 
irregular a site was not likely to 
be built upon until most of the 
available level surface had been 
taken up, for even in masonry of 
much higher development than 
can be found in Tusayan the 
builders, unable to overcome 
such obstacles as a large mass 
of protruding rock, have accom- 
modated their buildings to such 
irregularities. This is very 
noticeable in the center cluster 
of Mummy Cave (in Canyon del 
Muerto, Arizona), where a large 
mass of sandstone, fallen from 
the roof of the rocky niche in 
which the houses were built, has
