JEANCON] EXCAVATIONS IN THE CHAMA VALLEY 35 
several of these which furnished pastes of a different composition. 
Some of the pottery is made from a paste having a large content of 
gypsum, as is Shown by the hardness and color of the pieces. The 
red ware is represented in a small proportion in the collection, 
although there was a much larger percentage of red sherds scattered 
over the surface of the ground than is shown in the reconstructed 
pieces. No red pieces were found whole. Forms and decorations 
of the red ware would indicate that they were not made at Po-shu, 
but were brought in from other places, such as Puye, Frijoles Cafion, 
and Frijolito. Sherds of coiled ware differ very much in hardness 
and kind of paste. No pottery with basket impressions was found. 
Taken as a whole, the pottery presents a great variety of form and 
decoration. Unique treatment of well-known designs and a certain 
boldness in the execution of the decoration often occur. If Po-shu 
was a late pre-Spanish pueblo we can in a measure account for the 
great variety of pottery of different periods which was found. 
The distribution of the pottery of different periods was always the 
same inalltherooms. In thesame room, on the same floor level, would 
be found coiled ware, black cooking ware, sometimes of the crudest 
type, biscuit ware, incised ware, and red ware. All types were repre- 
sented. This did not occur in isolated cases but was the rule all 
through the ruin. The surface of the ground all over the ruin site 
was covered with tons of sherds of every type, and while at first it 
seemed that in some locations there was more of one kind of ware 
than another, still, after carefully studying the whole surface, it was 
concluded that while in a few locations one type might have a slight 
preponderance, yet as a whole the distribution was practically the 
same all over the site. 
_ One phase of the distribution of the broken pottery was this: A 
portion of a pot would be found in one location and the missing parts 
would sometimes be found in an entirely different location. In the 
case of a red Puye piece, a large fragment was found in location 3, 
and two weeks later, at a distance of over 188 m. away, in location 
7, the remaining pieces were found. The same thing occurred in 
several instances. Again we would find a fragment of a pot in one 
room and never find any more of it, even after searching with the 
greatest care the room in which it was found and all the surrounding 
rooms. 
It is to be regretted that in a few cases only small fragments of most 
interestingly decorated pieces were recovered. Where there was any 
suspicion that auything interesting was in the room, all of the earth 
removed was screened at least twice and often three times through 
screens of three different sized mesh. 
Only one medium sized and four large pieces were found whole. 
Seventeen small pieces were whole when found. There were very
