of the red ware. Again, it might be argued that the simplicity of 
some of the patterns of the incised ware would give it an earlier place 
in the chronology. This would not necessarily follow. With the 
difference in paste and the difficulty of a new method of applying a 
decoration, it is natural to . ~ 
find pieces that are not so 
well made, just as we have 
seen that some of the biscuit 
ware is better than others. 
During the author’s excava- 
tions on the Rio Oso, some 
years ago, he found some 
very elaborate designs in the 
incised ware. Some of these 
were wonderfully well exe- 
cuted and showed a finish 
that could only be obtained 
by long practice. On the Rio 
Oso most of the finer designs 
were composed of leaves and Fig. 21.—Decoration on biscuit ware water jar. 
branches of ferns. At Po-shu 
they had evidently not attained such a high degree of efficiency and 
the designs are simpler. At Po-shu the incisions were applied to 
different sized pots and dishes. Some very handsome small pieces 
were found, and one water jar was taken out whole and is the finest 
specimen of incised ware that the 
author has ever seen. 
Plate 42, A, is a small bowl. 
The sharp incurve at the top is 
typical of the incised ware and 
does not occur in the small pieces 
of the biscuit ware. The decora- 
tion is simple, consisting of trian- 
gles and oblique lines within the 
triangles, 
The other designs in Figures 
23-26 were taken from sherds that 
were found in the ruin and show 
some of the variations that were 
used. 
The graceful form of Plate 44, B, makes a pleasing appearance and 
suggests that the piece is a copy of a large water jar with certain 
modifications, It is broader and not so tall as a water jar, but in 
the smaller piece these points seem to improve its general appear-
