212 KOLITHIC IMPLEMENTS FROM THE PLATEAU 



waste of material, but I find that the shape of the flint is par- 

 ticularly well adapted for grasping in the hand, and that the 

 maker would seem to have taken this into consideration in 

 selecting the position for the hollow. 



The only other really abundant implement is the borer, 

 which, as its name implies, is a pointed tool- used for making 

 holes in soft substances such as wood. In some the points are 

 short while in others they are long and tapering. Fig. 5 is a 

 good example. 



The massive pointed implement represented by fig. 6 is 

 noteworthy. I can say little more of this than that there are 

 many ways in which such an implement could j be employed.

The working, being of an opaque yellow colour, is much lighter 

 than the rest of the flint. As in the other specimens figured in 

 this paper the reverse side is a more or less plane surface. 



The implements found in the plateau gravel range over a 

 very long period of time. This is shewn by the association of 

 unworn with much rolled specimens, and by the occurrence of the 

 most crude forms side by side with comparatively well-finished 

 examples. 



2. The bluntly pointed implements though resembling Borers are probably double Spoke- 

 shaves. Rutot (I.e.) says "les poinCons, qui ne sont peutetre que de simples grattoirs a deux 

 encoches, la point £tant sans usage,"
