CHIPPED IMPLEMENTS. 



Fig. 12. 



Flint flake. 



on village sites, where implements generally have been chipped. Singly 

 this form does not often occur, showing, I think, it is a chance flake only. 

 There is a general resemblance running through this 

 pattern of chipped flint and the spoon-shaped scrapers; 

 but the absence of smoothed or bevelled fig. vs. 

 edges enables a distinction readily to be 

 made. 



Fig. 12, likewise, is a chip or flake 

 only, but one so similar in outline to Fig. 2 

 that it might well have been used as a 

 cutting tool. The difference between the 

 two, however, is quite marked. The one 

 has a well-defined secondarily chipped 

 cutting edge; the flake, Fig. 12, has but 

 the naturally thin edge, characteristic of a splinter of flint of 

 allied mineral. 



Implements for drilling: Perforators. — The ordinary 

 stone drill, so common in the Atlantic coast States, and occur- 

 ring in numbers in the Oregon shellmounds, as shown by the 

 beautiful specimens collected by Mr. Paul Schumacher (Pea- 

 body Mus., No. 7636), is not represented by any specimens 

 from Dos Pueblos, although the existence of the Oregon 

 specimens renders it probable that they were in use by the 

 California coast tribes. 



Another and almost unique form was met with, however, 

 which, for want of any definite knowledge of its use, is here 

 provisionally described as a drill or perforator, the distinction 

 being drawn between the two that drills were used in boring 

 in stone, and so were rapidly worn away, while a perforator 

 was intended for making holes in softer substances. This dis- 

 tinction may, indeed, not be warranted, but the variation in 

 the character of these pointed flints suggests this difference in 



their USe. Flint drill.
