ABORIGINAL CHIPPED STONE IMPLEMENTS OF NEW YORK 33 



symmetrical, but in some examples the surface is so distinctly 

 curved as to leave no doubt of their being knives. This is true of 

 other forms. 



Fig. 72 is an unusual form of the triangular arrow or knife, hav- 

 ing a truncate base and convex sides. It is of common flint, one and 

 one quarter inches long and very thin. This comes from Owego, 

 on the Susquehanna, and is quite rare in this state, and probably 

 elsewhere. Neither the truncate base, nor the convex edges are 

 features of our triangular arrows. Usually the base is indented, and 

 the sides straight, but in larger implements both features may appear, 

 and often do, separately or together. 



Fig. 73 is a broad, notched, and finely serrated arrow-head of dark 

 flint, from Seneca river and one and seven eighths inches long. Dis- 

 tinctly serrated flints are quite rare in New York, but frequent 

 farther west and south. Those most distinctly serrated, and preserv- 

 ing the knife or arrow form, have been considered saws, and might 

 well have been used as such. This was Evans' view of those found 

 in Great Britain, but it has met with but moderate endorsement here. 

 This feature, however, is so conspicuous in some that they will here- 

 after be referred to as saws in this paper, simply as a possible use. 



Fig. 74 is a thick stemmed arrow-head of dark flint, two and one 

 half inches long, and found on Seneca river. It is distinctly shoul- 

 dered, and has a convex base and edges. The form is quite common. 

 Fig. 75 is of quite a different character, resembling some before 

 figured, but with a narrower base, the lateral edges also presenting 

 two nearly straight lines. This is two and one eighth inches long, 

 rather thin and of dark common hornstone, from the same vicinity. 

 Fig. 76 is quite curious in form, although one of the stemmed arrows 

 with expanding bases. It is quite thick, while at the same time 

 slender in outline, and is of dark flint, two inches long. The work is 

 rather coarse. 



Fig. yy is almost unique, while having the leading features of some 

 preceding forms. It is one and one half inches wide, and but one 

 and one quarter long, broadly shouldered, and with a concave ex- 

 panding base. The straight edges meet at an obtuse angle. It is of 

 light colored flint, rather thick, and like the last, comes from the
