POLISHED STONE ARTICLES USED BY THE NEW YORK ABORIGINES 67 



But a few typical specimens are figured, but these knives vary 

 much in proportions and details. The barbs are usually formed 

 by cutting a groove between the cutting edge and tang, and the 

 notches may be simply cuts or half circular grooves. The surface 

 is usually ground all over, and all is polished except the flattened 

 tang, which is often slightly roughened by a coarser grinding. In 

 Eskimo knives this is inserted in a handle, and the New York speci- 

 mens are usually beveled for this purpose. A few others may be 

 mentioned. 



One of greenish slate, from Baldwinsville, is one and three fourths 

 long by one and one fourth inches wide, and is barbed and notched. 

 A similar one is of the same dimensions. A slender one of dark 

 slate is barbed, but has the base broken. It is four and three fourths 

 inches long by one and one half wide. A curious one of red slate 

 is very broad. It is broken, but was originally three and one fourth 

 long by two and one fourth inches broad. It may have been a little 

 longer, but the edges have more than the usual convex sweep. All 

 these are from the same place. 



Another broken one, from the same locality, is of dark slate, 

 shouldered, and without lateral notches. The present size is three 

 and one fourth by one and one half inches, and it was once a fine 

 implement. One which is barbed and has a convex edge, is flat in 

 the center, instead of having the usual ridge. It is two and three 

 fourths by one and one half inches. Another fine one of grey slate, 

 also from the Seneca River, has a very sharp point, and is seven 

 and one half by one and one fourth inches, an unusual size. 



A small one of grey slate, from the Oswego River, is barbed, and 

 has both blade and base very tapering. It is two inches by one. A 

 long one of grey slate, from Baldwinsville, is also barbed, and is 

 four and one half by one and three eighths inches. A handsome 

 one of brown slate is from the same place, and is shouldered. The 

 surface is rounded and not distinctly ridged. It is three and one 

 eighth inches long by one and one fourth broad. 



A shouldered one of black slate, from the Oswego River, is three 

 and one fourth inches long by one and one fourth wide. One 

 from Onondaga Lake is barbed and has the sharp end neatly
