THE STONE AGE IN NEW JERSEY. 149 
not grooved,* and illustrate the various shapes that occur in 
varying numbers. A majority of the axes found in New Jersey 
are water-worn pebbles of sandstone, porphyry, granite, ser- 
pentine, etc., that have originally borne more or less resem- 
blance to some one of the shapes then in use. Such cobble stones 
are usually grooved, on each side and beneath, and the stone worn 
smooth upon the upper edge (Fig. 10), which is a common shape ; 
or the groove circles the stone (Fig. 11). In a number of speci- 
mens, the original surface of the stone has been ground or chipped 
away from the groove making it a more marked feature in the im- 
plement (Fig. 12). This 
specimen has had con- 
siderable work put upon 
it, as is seen by the gen- 
eral elegance of the out- 
line. There is no indica- 
tion of its having once 
been polished; and the 
edge, which is now mu- 
tilated, was probably 
never very sharp. As a 
Tule, these cobble stone 
axes are not polished 
except upon the edge; 
the axe (Fig. 10) and the 
beautiful specimen (Fig. 
15) being exceptions. In 
size, axes of this des- 1-2 natural size (side view). 1-2 natural size 
cription vary very much, 
the little specimen (Fig. 13) being but three inches in length by 
two in breadth, and is the smallest grooved example that we 
have. It is of sandstone, and a repetition in outline of the more 
accurately made specimen (Fig. 10). On the other hand, the 
uncouth axe (Fig. 14) is an example of the maximum size of this 
style. While this specimen, unquestionably, is an axe, it is of 
such rude workmanship, that we can scarcely imagine any man so 
primitive, as to be willing to make use of it. Its greatest length
