THE STONE AGE IN NEW JERSEY. 209 
These sites of skilled arrow-makers’ workshops were usually on 
projecting points op bluffs overlooking a broad expanse of country ; 
and when once visited, are known immediately by the countless 
numbers of thin, splintery flakes that cover the whole ground. 
One such place in particular had evi- 
dently been so occupied for many gen r- 
ations, or by a score o° arrow makers 
during their lifetime, considering the vast 
amount of chips and refuse material on 
the ground. It was a paradise for the 
mineralogist, for all our mineral produc- 
tions, suitable for chipping, seemed to 
be there in abundance. After a rain, 
when the chips were free from dust, the 
many colored jaspers presented a beau. g 
tiful appearance. Isolated specimens of L 
minerals, available for arrow making, are 
frequently found. in the fields, that do not belong there according 
to the given “localities” of mineralogists. One of the finest 
agates we have ever seen, was a partially 
chipped mass found just beyond the town 
limits of Trenton, N. J. 
Triangular arrowheads, with concave bases, 
are very abundant and present some little 
variations in detail. Figure ‘1 is a beau- 
G ` tiful specimen of one of these varieties, and 
Natural size. is of a shape and size that we frequently 
meet with. They are mostly of black 
quartzose stone, or cut from a hard piece of 
slate. The specimen figured is of yellow 
jasper, with veins of white quartz running 
h it. A second illustration of this

== of Fig. 52. It is one of the handsomest 
specimens that we have ever seen. It is cut 
from a greenish gray jasper, and remains in its perfect condition. 
ake the preceding this size and form also is mostly represented

more brittle than is this many colored jasper, of which so many of 
Cur arrowheads have been made. A third variety of this class of
