JEANCON ] EXCAVATIONS IN THE CHAMA VALLEY 1 ay 
only able to dig a trench about a meter in width and 40 cm. in depth 
around the inside of the walls. At that rate it would have taken 
us almost two weeks to completely uncover the whole building, and 
it was abandoned for some other time. (PI. 10.) 
The building was unusually large, as will be seen from the diagram 
in Figure 3. The same types of walls and pottery were found as in 
all other locations of the ruin. There are evidences that the origi- 
nal building was raised several feet above the ground, thus making 
it only semisubterranean. On the east side, in the interior, were the 
charred remains of two posts which assisted in holding up the roof. 
As the wooden portions of the building had all been destroyed by 
fire there was no way of telling how the roof beams were arranged. 
A curious thing in connection with the plaster on the walls was that 
it was white, not colored, as we found the plaster in so many places; 
the floor was also covered with a wash of white. There were seven 
coats of plaster on the walls. 
STONE ARTIFACTS 
While the stone artifacts of the collection do not present any strik- 
ingly new features, there are many of them that are of great interest. 
Especially interesting are the partly formed pieces which occur in 
large numbers. 
A curious thing in connection with the finding cf the stone artifacts 
is that in direct conjunction with the crudest types were found some 
of the finest specimens that could be desired. It does not necessa- 
rily follow that the same person made both types, but it is logical to 
suppose that excellent workers of stone dwelt in the village, and 
while some of the finer pieces may have been acquired by barter, 
undoubtedly some of the cruder ones were made by experienced 
workmen. Possibly it was the intention to finish some of the roughly 
chipped pieces, but for reasons unknown to us this was not done. 
It is also possible that some of the roughly made pieces were never 
intended to be finished, and as they answered the purpose for which 
they were intended they were left as they are now. There are speci- 
mens in the collection representing almost every stage of the work, 
from the beginning to the end of the process. 
CHIPPED IMPLEMENTS 
AXES 
Axes range from the crudest forms and workmanship to beauti- 
fully made and polished specimens. The technique is interesting, in 
that it shows many varieties of chipping. 
With the exception of the crudely chipped two-headed ax, it is my 
belief that all of the axes were for domestic purposes. The sharp
