vision, that after the jasper had been mined it 

 was directly subjected to a hammering process 

 that determined the precise quality of the mass. 

 This was a necessary preliminary, for the imple- 

 ment-maker and the miner were not one and the 

 same person, or, if so, pursued the two occupations 

 at different times. 



Before considering the adjacent workshop sites, 

 let me prevent a possible misconception. Here is 

 not the one sole source of supply from which the 

 Indians derived jasper, but, I take it, the principal 

 one. It is true a block of jasper, if pure and
