FLAKED AND CHIPPED STONE. 



b. Implements with chipiDed convex edges, mostly serrated at the opposite 

 side, or provided with a row of stems, perhaps for being more securely 

 hafted (Fig. 43, gray flint, California). The specimens of this character 

 were all obtained from California, where the aborigines are known to 

 have employed asphaltum for cementing their stone tools into handles. 



CUTTING TOOLS (J). 



c. Small sickle-shaped implements designed, as it seems, for some cutting 



purpose (Fig. 44, dark-brown jasper, California). 



d. Crescent-shaped implements, some of them truncated at one end ; probably 



knives and saws (Fig. 45, lydite, Pennsylvania). A somewhat similar 

 type occurs in Northern Europe. 



e. Arrow-head-shaped (notched or stemmed) implements, ajiparently repre- 



senting sawing and cutting tools, the part used being either one of the 

 sides which is convex, or the obtuse point (Fig. 46, reddish jasper, Ten- 

 nessee; Fig. 47, semi-opal, Georgia). 



f. Roughly chipped implements with convex edges and massive backs. They 



resemble the "choppers" found in some caves of Southei-n France, and 

 described by Lartet and Christy in the " Reliquiae Aquitanica; '' (Fig. 48, 

 gray hornstone, shell-heap, Maine). 



10. Dagger-shaped Implements. — The dagger form is in most cases indi- 

 cated rather than fully developed. There is, however, in the collection a
