ADMINISTRATIVE REPORT 13 
The inhabitants of the great compound first described 
obtained their water supply by means of two principal 
reservoirs fed by the drainage from the great sandstone 
shelf on the southern slope of the mesa summit. These 
reservoirs are natural depressions in the rock, but the capac- 
ity of the larger one, which measures 35 by 90 feet and is 
about 5 feet in maximum depth, has been greatly augmented 
on the western side by an artificial retaining wall 14 feet 
long and 10 feet in thickness, with an exposed face of 25 
feet on the reservoir side. So well did this reservoir evi- 
dently serve the ancient mesa dwellers that during seasons 
of unusual rain, water still stands to a considerable depth 
within the depression. The smaller reservoir is triangular 
in outline and measures about 15 by 19 feet. An inter- 
esting feature in connection with the larger reservoir is the 
remains of a rude dike extending 60 feet along the rocky 
shelf above referred to, built for the purpose of diverting the 
flow of rain water from its natural course into the reservoir. 
It is not yet known where the ancients of this pueblo 
customarily buried their dead, but probably the interments 
were made in the talus of the mesa, as is the case with the 
Hopi, of Arizona, to-day. There was found, however, in the 
corner of the shallow cavern in the northern face of the mesa, 
above the talus, a small cist, formed by a low and broken 
wall of masonry, which contained the somewhat incomplete 
skeletons of two adult females, one incomplete skeleton of 
a boy, and the incomplete and defective skeletons of two 
infants. With one exception these remains had been greatly 
disturbed by rats, which had burrowed their way through 
the bones and their accompaniments to the bottom of the 
cist and fairly filled the repository with cactus spines, excreta, 
and other débris of nest building. The remains were accom- 
panied with several pottery vessels, chiefly bowls, one of 
which was covered with a well-preserved mat, plaited of a 
fibrous plant which Mr. Lyster H. Dewey, of the Department 
of Agriculture, identifies as a scirpus, and almost certainly 
Scripus validus. The ornamentation of this pottery, as well 
as of the numerous sherds scattered about the ruins, consists 
of plain red, black on red, white on red, plain black, black
