336 IMPLEMENTS OF STONE AND FLINT. 



No. 4 (left hand lower row) is a more unfinished but 

 undoubtedly worked stone of the same rock, with the flat 

 underside only partly flattened, a most useful specimen in 

 showing the method of production. 



No. 5 (right hand lower row) is a nearly finished speci- 

 men of the same stone in which the natural angles are made 

 use of. 



No one, I think, can study these without coming to the 

 conclusion that these are artifacts.
