scraper-knife-flakes, owing to the continuous survival of the type 

 due probably to the facility of shaping or evolving the implement 

 from any loose stone. But some, such as Figs. 102 and 103, 

 have such a worn appearance that even a long continuation of eolian 

 agencies would be required to impart the same, and the absence of 

 bouchers cannot in their case be claimed for their rejuvenation. 



That this absence may be accidental is proved by the fact that 

 although no palaeolith in the shape of a tongue-shaped or cleaver- 

 like tool can be said to have hitherto been discovered in the East 

 London beach deposit, nor in the " broken ridges just a little back 

 of the beach " where very large worn flakes do, however, occur, yet 

 Mr. J. Wood has quite lately discovered at no great distance from 

 there, near the mouth of the Nahoon River, bouchers, mostly huge 

 (judging from the examples he sent us) ''■'■ lying together with flakes 

 of the kind which I consider belongs to the South African 

 Palteolithic. 



And thus the discrepancy between the styles of the stone tools 

 in McKay's photograph are explained. 



The !'Kwes, mullers, some of the flakes, and the "pygmies" 

 are recent additions deposited at or near the place where imple- 

 ments of palaeolithic type had gravitated, or been manufactured very 

 long before the Strand Looper had left there his own mark of 

 occupation. 



* These bouchers are made of volcanic rock or of Karroo sandstone. They are 

 very roughly trimmed, and all those sent us are large. None is tongue- or almond- 

 shaped ; some are pointed at both ends ; in others, made of sandstone, the butt 

 retains the contour of the rolled pebble. The flakes are of the usual knife-scraper 

 shape, but are plainly worn.
