STONE AGE IN NEW JERSEY. 287 



tliesame type with smooth edges, we find tliat theyare invariably thinner. 

 To secure the serrated edge, it was probably necessary to make them 

 so; and, of course, these thiu specimens were more frequently broken in 

 the manufacture, and more liable to injury in the daily i<se to which they 

 were put, to say nothing of the two centuries of plowing and other 

 exposures to which they have been subjected since the termination of 

 the stone age in New Jersey. 



Figure G5 represents a beautiful form of large arrow-head, which we 

 have thus far only been able to duplicate once. It is of a slaty stone, 

 not smoothly chipped over the surface, remarkable for accuracy of 

 outline, and is of unusual size. Another noticeable feature is the small 

 size of the stem, or base, in comparison with the body of the speci- 

 men. The surface is so weather-worn and soft, that the exact mineral- 

 ogical nature of the material cannot be determined. Exclusive of the 

 base, the specimen measures two inches in length by one inch and 

 three-quarters in greatest width. We believe it to be an arrow, rather 

 than a spear point, as the stem has never been very strong for so large 

 a specimen, and there would be less strain upon it in its use as an arrow- 

 head than as a spear-point ; in the latter case, the struggles of the ani- 

 mal w'ould be likely to break it off while the shaft was being held in the 

 grasp of the hunter. Moreover, weight is to be considered in the recog- 

 nition of these doubtful specimens, and figure 05 is no heavier than 

 many of the smaller jasper arrow-points. 



Figure GG is a form of notched-base arrow-head, more or less com- 

 mon in all localities. In general appearance, it is much like figures 

 62 and G4, but is peculiar in having a central notch in the stem. The 

 object of this third notch is not clear. The specimen is chipped from a 

 black, slat3" stone, is very thin, and the sides have been slightly ser- 

 rated. These si)ccimeus are not very variable in size, but few having 

 been found much larger, and but two or three smaller. Inasmuch as 

 they are very noticeably serrated arrow-points, we give two illustrations 

 of both the larger and smaller specimens. 



Figure G7 represents a tri-notched, stemmed arrow-head, perfect in 

 detail, and particularly interesting from the deep, well-marked serrations 

 that extend along the greater portion of the sides. The specimen meas- 

 ures two and one-eighth inches in length from the bottom of the cen- 

 tral notch to the point. It is chipped from a porous, yellowish jasper 

 or agate ; the extreme i)oint being more dense and glassy than the body 

 of the specimen. There is no doubt this specimen was used exclusively 

 as an arrow-point. We have a few examples similar in size and charac- 

 ter from New Jersey, but all somewhat broken. The one figured is 

 from Indiana. 



Figure 68 represents a third example of triple-notched arrow-point; 

 the barb on one side, however, being broken ofi". It is of yellow jasper, 

 with deeply-serrated sides and an acute point. We have seldom seen 

 an arrow-point better suited for killing birds and small mammals. With
