6 THE AMERICAN NATURALIST. 
Besides the tools whose functions are indicated by their forms, 
as perforators, scrapers, etc., chipped flint was used in America 
for cutting implements and as points for various kinds of pro- 
jectiles, including arrows, light spears thrown with a throwing 
stick, harpoons with detachable heads, hand lances, small jave- 
lins, and thrusting weapons; but the greater number of flint 
implements of the common types, of lengths varying from 
about two inches to seven inches, were probably used as knife 
blades. Nor are we safe in assuming that the stemmed and 
notched forms were all projectile points, as an examination of 
Fig. 2, 6, and Fig. 3 will show. It is of course impossible with 
our present knowledge to classify correctly all forms of chipped 
implements, but a study of the few prehistoric hafted examples 
known will materially aid us in the work. .
