probably merely because of the hooked ends of the lines. In sketch 
183 there are ‘leaning foot’’ elements which are given the same 
interpretation as those placed in an erect position, but with the added 
qualificatory term “leaning.” Sketch 184, although the angles of the 
elements are obtuse, is still called by the terms bent and broken 
back, leg, or grasshopper, but the name “hook”’ is not applied, being 
reserved for figures like sketch 185, where the angle is acute. These 
two figures do not properly belong to this group on account of their 
different angles, but since they so closely resemble the right-angled 
figures and receive practically the same names, and since they are 
not very common, they have been treated here for convenience sake. 
Sketch 186 gives an odd trident form called fish spear or bird’s foot. 
There is no doubt that, from the character of interpretations given 
the chevron and the right angle with one long side, such as grass- 
hopper, broken back, or bent middle, the people sense a vague re- 
semblance between the two. Nevertheless they are more often 
distinguished by their names than confused, especially since with the 
latter the one side of the angle is so much shorter than the other. 
As with all other groups, the variety of names have this in common, 
that they refer to long, narrow, bent objects or those which are 
distinguished by such features. The wave is no exception, because 
its thin broken crest is one of its conspicuous features. 
The meander.—The meander or simple key figure is generally called 
mouth or notch; no distinction is made for its horizontal or vertical 
arrangement (sketches 187, 188). It is also termed snake or snake 
track. Even in a more elaborate form, as shown in sketches 189 and 
190, or doubled, as in 191, it is always the mouth pattern to those 
who know design names well. When the inner square figure is en- 
tirely closed, as in sketch 192, some people call the resulting pat- 
tern a variation of the grave box. A good all-over arrangement is 
shown in sketch 193. Sketches 194 to 196 (p. 316), showing the 
meander with a facing along one edge, which consists of a straight 
line, are aptly given the additional interpretation caterpillar, and 
more closely resemble the creatures than do most of the other figures 
so named. Sketches 197 and 198 (p. 316) may be considered as 
belonging either with this group or with the right-angle group so 
often called leg or root digger (sketches 172, 180, and 181). They 
are named caterpillar, snail, and head patterns. Sketch 197 is some- 
times specially termed duck’s head. 
Properly speaking, sketches 199 and 200 (p. 316) show meanders of 
larger conception, which are also related to step and ladder as well as 
to checker figures and to the zigzag composed of vertical and horizon- 
tal sections. They are designated as zigzags or steps, and are also 
given the fanciful appellations of mountains, clouds, necklaces, and 
stepped half circles on account of their shape. Probably because of
