84 STONE ART. [eth.ann.13 



The Bureau collection includes the following specimens: 



The high polish sometimes found on the top of a round-pointed celt 

 may be due to its working slightly in the socket in its handle of wood, 

 deerhoni, or other material. 

 By celts having a scraper-form edge is meant those having the edge 

 to one side of the median line, due to constant use of one 

 face. This face, at the edge, is in a straight line from side 

 to side; it may have a chisel-like flattening, or may curve 

 toward the iniddle of the celt for a short 

 distance and then have the same form to 

 the top as the other face, which is convex 

 or curved, as in the ordinary hatchet-celt. 

 They form a medium between celts whose 

 faces gradually curve from top to edge, 

 and the celt-scrapers which are flat on one 

 side. Among the thicker celts this form is 

 quite rare, though several, especially one 

 from Kanawha valley, West Virginia (rep- 

 resented in figure74), are quite pronounced. 

 Inthe thinner specimeus,however, a majority are of this 

 pattern, while in some types, nearly all indeed, even 

 those up to G inches long, are so beveled. The type, 

 of which an illustration is shown in figure 71, is of very 

 hard black slate; the same form is presented in figures 66 and 70. 



From Bai'tow county, Georgia, is a scraper made from the edge of 

 a celt which has been broken diagonally across from one face to the 

 other. A stem like that of a spear-head has been formed by chipping 

 away the sides of the part broken, which gives a convenient attach- 

 ment for a handle; the original edge is unchanged except in the wear 

 which has resulted from its new use.
