PREHISTORIC FISHING. 



Figs. 202 and 203 (on the preceding page) . Two hooks cut from the shell 

 of Mytilus Calif ornianus, and exhibiting on both sides the natural surfaces of 

 the valve, which is from one-eighth to one-fourth of an inch in thickness. They 

 resemble so much the originals of Figs. 194 and 195 that a further description 

 is unnecessary. Traces of asphaltum are seen on the shanks of these hooks. 

 They were found by Mr. Stephen Bowers on Santa Cruz Island. 



FIGS. 204 and 205. Shell fish-hooks. Santa Cruz Island. (26252). 



Figs. 204 and 205. Of the same material, and also obtained at Santa Cruz 

 Island by Mr. Bowers, are the hooks represented by these two figures, which 

 show with sufficient distinctness in what manner the line was fastened. 



FIG. 206. Shell fish-hook. San Nicolas Island. (20406). 



Fig. 206. This specimen, cut from a piece of the Haliotis, is apparently 

 very old, yet still retains the beautiful iridescence of that shell. Both curves are 

 cut angularly. The point is broken off, and the upper portion of the shank 

 damaged. The thickness is about three-sixteenths of an inch. This specimen 

 was obtained by Mr. Schumacher on San Nicolas Island.
