feature. It is one of the finest examples of the kind, and is made of 

 dark olive green slate, five by two inches. It was found on the 

 Seneca River, west of Cross Lake. Fig. 55 has a somewhat similar 

 dorsal groove, and is of ironstone, with a sharply ridged back, 

 beveled down to the cutting edge. In section it is triangular, and 

 the dimensions are four and one eighth by one and seven eighths 

 inches. It was found near Cayuga Lake. 



Fig. 61 is a broad gouge of rare form, closely resembling that 

 of some celts. It is a handsome mottled stone four and one 

 eighth by two and three eighths inches, and comes from the Oswego 

 River. The back is ridged, and the central part of the upper sur- 

 face at first slightly depressed, then quickly hollowed to the edge. 

 Both ends are neatly rounded. 



Fig. 72 is a reduced illustration of a curious implement combining 

 the celt and gouge. The groove extends about half way from 

 one end, while the other, which is broader, has a chisel edge. Toward 

 the gouge end it is three eighths of an inch thick. It is picked and 

 ground, and the dimensions are two and three fourths by one and 

 three fourths inches. It comes from Seneca Lake. 



An angular gouge of green gneiss from Jefferson County, has an 

 angular groove, ending squarely at the upper end about midway 

 in the implement. This is an unusual feature. It is six sided in 

 section, nine and one eighth by one and three fourths inches wide, 

 and is every way a remarkable article. Another large and curious 

 gouge is from South Lake, Herkimer County. It is of black iron- 

 stone, and has a deep and long secondary groove in the center, with 

 finer ones on either side of this. The length of the implement is 

 12^ and the breadth two and one fourth inches. 



Usually dorsal grooves are confined to the long gouges, but one 

 from Brewerton, having the gouge cavity about one third of the 

 length, has a broad and deep groove across the back, with a broad 

 and shallow one above this. The back is somewhat flat, while the 

 front is much curved. It is of light cream colored limestone, four 

 and one quarter by two and three eighths inches wide. A long 

 gouge from the same place is much contracted at the upper end, 

 and is picked all over. It is of sandstone, six and seven eighths
