arrowheads, is given in figure 53. The base is so slightly 
curved as to make one doubt where to place the specimen. It is 
very nearly an equilateral triangle, but is particularly to be noticed, 
in that it has not been made with a well defined point; or if so 
originally, has since been sharpened down to a curved edge, and 
again used as an arrowpoint. Such arrowheads must have been 
shot with tremendous force to render them 
effective, for the cutting edge is never 
sharp as points that have been chipped; 
and as they now are, these curved topped 
specimens seem better adapted to crush 
than to penetrate. The specimen described —

form immediately preceding this, is given in Fig. 54, of slate, but 
well cut: this style is very sparingly met with. The peculiarity, 
as will be seen at a glance, consists in the manner in which the — 
point has been chipped. A single specimen of this style would 
probably excite no comment. The peculiarity would be considered 
as resulting from a chance blow of the arrow maker. This how- 
ever is proved not to be so from the fact that a score oF more 4 
have been gathered, each, in size and mineral, Fig. Ko fo 
the fac-simile of the others. It is probable 
that one maker may have fashioned all that 
we have found, and the style originated and 
died with him. 
A handsome form is represented in Fig. 55. 
It has the appearance at first glance of having 
been barbed as in Fig. 50 but the carefully 
chipped sides of the base induce us to believe 
that it is now in its original condition. With 
a shaft much narrower than the base of the 
specimen, this would be one of the most ef- 
fective arrowpoints that we have figured. It 
is not a common variety in this neighborhood 
(Trenton, N. J.) but we have met with quite a num

ments of this form are much more abundant than of
