the fact that in a line of crosses depicted on a bowl one of the crosses 
is replaced by a design of similar character. The arms of the cross are 
represented; their intersection is left in white. The interpretation of 
figure 317 as a highly conventionalized bird design is also in accord 
with the same interpretation of a number of similar, although less com- 
plicated, figures which appear with crosses. Thus the three arms of 
plate CLX, a, have highly conventionalized bird symbols attached to 
their extremities. In the cross figure shown in plate CLVIII, d, we find 
four bird figures with short, stumpy tail-feathers. These highly con-

ventionalized birds, with the head in the form of a crook and the tail- 
feathers as parallel lines, are illustrated on many pottery objects, 
nowhere better, however, than in those shown in plates CXXVI, a, and 
CLXx,¢. Figure 318 may be compared with figure 317, 
Numerous modifications of a key pattern, often assuming a double 
triangular form, but with rectangular elements, are found on the exte- 
rior of many food bowls. These are variations of a pattern the sim- 
plest form of which is shown in figure 319, Resolving this figure into 
Fic. 322—W -pattern; terminal spurs 
two parts by drawing a median line, we find the arrangement is bilat- 
erally symmetrical, the two sides exactly corresponding. ach side 
consists of a simple key pattern with the shank inclined to the rim of 
the bowl and a bird emblem at its junction with the other member. 
In figure 320 there is a greater development of this pattern by an 
elaboration of the key, which is continued in a line resembling a 
square spiral. There are also dentations on a section of the edge of 
the lines.
