BLACK-AND-WHITE WARE 
Trecunouocy: The paste is of a clearer white than is common in 
any other group of black-and-white ware which we have observed, 
with the exception of that from Chaco Canyon. Tempering nor- 
mally consists of very minute angular grains of basaltic (?) rock, 
so fine that they can sometimes be made out only with the aid of 
a strong hand lens. The slip is always fine and, unless fire-clouded 
or otherwise marred in baking, is of a clear, even white. Some of 
the pieces are made of a paste so perfect that the surface, so far as 
can be ascertained, was not treated with any slip at all, the decoration 
having been applied directly to the well-smoothed body clay. This 
procedure is common, so far as the authors know, only in the yellow 
ware of the ancient Hopi ruins.t. Where slip is used it is confined, 
as elsewhere in the Southwest, to the visible parts of vessels. It is 
brought to an even finish, but is seldom highly polished. The pig- 
ment is clear, dull black, with a slightly bluish or slaty cast. Chem- 
ical analyses have not yet been made, but it is probable that it is 
an iron product, as determined by Nordenski6ld for the paint of 
Mesa Verde black-and-white.” 
Suapes: Ollas. (1) Flat upperbody with straight neck—The 
underbody is full, the shoulder abrupt, the upperbody flat and almost 
horizontal. The neck rises almost straight, but is a trifle smaller 
just below the orifice than it is at its base. The lip flares slightly. 
There are three decorative zones—the upper part of the underbody, 
the upperbody, and the neck. Specimens seem to average about 
9 inches high. There is evidently considerable variation in this type, 
both in details of proportion and in size; our material is all frag- 
mentary. The description given here is of a badly broken example 
from Ruin 8. Fewkes* figures a very fine one from the Little 
Colorado. 
(2) Globular body with high neck.—The body is globular, but is 
usually somewhat elongated vertically (pl. 53, a, 6). There is no 
true shoulder. The neck is high, but in most cases continues the 
curving lines of the body without an abrupt break. The lip turns 
outward rather gradually. Decoration zones are a narrow: band 
about the neck and a field consisting of the whole of the body from 
just below the neck to well below the point of greatest diameter. 
Height averages 15 inches, greatest diameter 14 inches. 
(3) Globular body with low neck.—The body is almost spherical. 
The orifice is relatively much larger than in the preceding types; 
the neck very low and abruptly outflaring. A single decorative

ris,, 1915, p: 6%).
