ARROWPOINTS, SPEARHEADS, AND KNIVES. 



909 



Figs. 128 and 129 (see Plate 31, fig. 2) belong to tlie same class. They 

 are from the same locality, Santa Barbara County, California, and 

 evidently the same material, which is stratified Hint 

 or chalcedony, lustrous, having the appearance of a 

 brilliant patina. The edges are parallel and the bases 

 slightly concave. 



VVe now pass to an implement having sutlicient re- 

 semblance to re(]uire its placement in Class C, and 

 although from the same locality as the foregoing im- 

 plement, it has such a difference of material, work- 

 manship, and apparently of service, tbat its manufac- 

 ture and use may have been separated from them by 

 long time or distance or perhaps both. Two speci- 

 mens of this kind are here shown (tigs. 130, 131). They 

 are from Dos Pueblos, Santa Barbara Countj' , Califor- 

 nia, are of black flint, and bear traces (especially the 

 larger, fig. 130) of bitumen having served as an attach- 

 ment for a handle. (See p. 900 and fig. 124.) 



Fig. 130 represents an implement, 10 inches long 

 and 1^ inches wide, its edges being perfectly straight 

 and parallel for 7i inches of the length, and of ex- 

 quisite workmanship. Fig. 131, though not so large 

 is equally as fine (Plate 31, fig. 4). The edges and 

 points are smooth and sharp. The chipping by which 

 they have been reduced has been fine, with small and 

 delicate flakes running from the edge to the center 

 ridge. An inspection of the illustrations will show 

 the beauty of the work. Both specimens bear traces 

 of the bitumen by which the shalt or handle was 

 fastened.

DIVISION II— TRIANGULAR. (Plate 32.) 



This division includes all arrowpoints or spearheads in the form of a 

 triangle, whether the bases or edges be straight, convex, or concave. 

 It might be that the concavity or convexity of the lines of the edges 

 would, in strict geometrical nomenclature, exclude this from being 

 called a triangle, but the author ignores this criticism and has kept 

 the name given by many others and understood by all. 



This class includes all kinds of triangles, whether equilateral or 

 isosceles, and whatever may be the relation of length between the
