plements as applied to artifacts under treatment. Hand-held ob- 

 jects in process of manufacture were 



rubbed on stationary grindstones (fig. 



205), and numerous examples have 



been observed where depressions and 



grooves are worn in the surfaces of 



rock bodies in situ (fig. 20G). 



Edged scraping tools of varied 

 forms were in univer- 



scraping Sal use bv primitive 



peoples, but little can 



be said regarding their use in the 



treatment of stone. There can be no 



doubt, however, that stone scrapers as 



well as knives of stone and metal 



served in shaping the softer stones, as 



catlinite, soapstonc, cannel coal, and 



fire clay. Artifacts made of these ma- 

 terials bear unmistakable traces of the 



employment of implements of this 

 type. Sharp - pointed 



En.i,aavin^c implements were em- 



ployed in engraving 



figures on stone surfaces, as countless 



examples indicate, but the particular 



tools employed are not readily identified
