by causing the weft threads to pass over one warp thread and then 
under two, and so on, instead of taking the warp threads in regular 
succession, one down, one up. The next weft thread takes a set 
oblique to the former, throwing up one of the two deposed by the 
preceding. In some twills it is one in three, or one in four.’”’ 
In the case of the twilled baskets of Po-shu the weave was one 
under and three over. <A curious thing in connection with one set of 
basket impressions is that one side of the clay shows a negative of 
the weave and the other side shows a positive. (Pl. 62.) Whether 
the basket rotted away from between the two pieces, or whether it 
rotted away before the top part was made we do not know, but both 
sides of the basket are seen and the two prints fit within each other 
exactly. The general appearance of the weave is that of a basket 
that is still made at Zuni, N. Mex., and said to be of very old origin. 
It also resembles the so-called diagonal weave that is found in the 
old Hopi and Zufii mantas. The fabric from which the baskets were 
made at Po-shu was probably yucca. A small part of one of these 
baskets was found, but it is very difficult to determine the material.

PICTOGRAPHS 
Only two pictographs were found during the excavation. The hills 
and the river bottoms in the vicinity were carefully searched, but 
yielded no results. 
On a rock 150 m. from the southwest corner of plaza No. 1 are two 
pictographs. One (pl.63,A)isa turkey cock. Thisis 25 cm. in height. 
Accompanying it is the picture of a snake which is 50 cm. in length. 
(P1.63,6.) On the top of the rock are rubbing places or cupping stones, 
and on the side of the rock below the tail of the bird are more cups. 
Just what the function of these cups was is not known. Ina former 
exploration on the Rio Oso the author saw many stones with the 
cups pounded or rubbed in them. Upon asking the Indians as to 
their meaning, it was claimed that no one knew what they were for. 
Finally one man was found who said that at certain times of the 
year, and during certain ceremonies, it was and still is the custom 
for the women to go at daybreak and pound on the rocks to attract 
the attention of the ‘‘Sun god.’’ The same rocks were always used, 
and that accounted for the holes. The informant’s name was Aniceto 
Swaso. The information is given here and the reader may draw his 
own conclusions. Ido not venture to say that it is or is not correct. 
SHRINES 
In making a reconnaissance of the surrounding country near the 
ruin we found many shrines and stone works that were at first rather 
mystifying. Leading from the ruin'in many directions were paths
