classed as arrowpoints, knives, drills, and scrapers. The materials 
are mainly jasper, flint, chalcedony, quartzite, and obsidian. The 
dull gloss or luster, which 
is particularly apparent 
on the obsidian imple- 
ments, shows them to be 
very old. In length these 
vary from 4 to 24 inches. 
The workmanship of 
many is poor, but some are 
of unusual beauty. A few 
ornaments are also figured. 
Two of these show diag- 
onal incised lines. 
It is impossible to say 
how many of these objects

dwellers on the mesas. 
The most notable feature in connection with the stone implements 
from the mesa sites is the lack in variety and quantity of everything 
but chipped instruments. 
BONE IMPLEMENTS 
Bone implements are not numerous. Besides three bone awls no 
other artifacts of bone were exhumed in the mesa ruins. 
As might be expected, all articles of wood and other perishable 
material not consumed by the burning of the buildings had entirely 
decomposed. 
SuMMARY 
The inhabitants of the mesas were an agricultural people whose 
domiciles were one-storied aggregations of cell-like chambers, usu- 
ally grouped to form a rectangle. Generally speaking, the rooms 
extended down into the earth, and with few exceptions the sections 
of the walls above ground were constructed of upright poles coy- 
ered with plaster. 
Thus far no kiva has been found in, or connected with, a jacal 
dwelling. It is possible, however, that when excavated some of 
the numerous circular pits will prove to have features linking them 
unmistakably to the kivas of later time.
