120 Annals of the South African Museum. 



The supposition that these cylindrical stones were used as anvils 

 is, of course, untenable. Fig. 166 is as smooth as if it had been 

 polished ; Fig. 167 shows no mark like that which a hammer would 

 leave, and the proposition that the huge pieces served as braying 

 tools would certainly not apply to Fig. 173, the ornamentation of 

 which makes it too uneven for effectively fulfilling this purpose. 



For the present it is safer to figure or mention these stone imple- 

 ments than to try to explain their purport.
