64 Annals of the South African Mnsewn. 



small ones in the sense that when a patch of small implements is 

 found, large flakes or coarse chippings are found in smaller numbers 

 comparatively. (2) Do the diabase implements occur in conjunction 

 with the quartzitic ? — Yes ; I can find no dividing line between any. 

 When I say that really all the large implements sent you, with a 

 great many more, were found on the river-banks within a distance 

 of 200 yards along the river, and about 50 yards from it, it will be 

 seen how very difiBcult it was to distinguish between their relative 

 positions ; but with regard to the small agate ones, they, or the 

 greater number of them, were found about a mile away associated 

 with large flakes. . . . 



" On the receipt of your letter I went to a spot about 500 yards 

 from where the implements were found. On a space of 10 feet 

 square I saw flakes, chips, &c., which I am sending you; they show 

 the variety well. I am of opinion that the sign of great age of many 

 of the large implements or flakes is due to weathering." * 



The Vereeniging find was made in 1905. Mr. Ivor Guest kindly 

 sent me a sketch-map of the locality. ^Yhen he visited Bosman's 

 Crossing at Stellenbosch he found that the talus conditions were 

 the same in both places. I pointed out the Bosman's site and all its 

 features to Mr. Leslie in 1908, and he informed me that the situation 

 was identical with that of Vereeniging, which he described as " a 

 talus of 4 or 5 feet in depth and extending some miles along the 

 banks of the Vaal River and about a mile wide ; implements both 

 large and small may be found in any part of it." 



With the evidence before us it is safe to conclude that the 

 Vereeniging deposit is another instance of accumulation in talus, 

 and this by degrees. 



Whether the first makers used quartzite, and those that followed 

 diabase for their manufacture is not likely to be conclusively 

 proved ; f I believe that they were not the same race, or had not the 

 same lithic culture or skill. As to the makers of the small, uncouth 

 agate or chert implements, we can, I think, consider them to have 

 been people, if not of another race, at least of one that had lost this 

 state of culture, and this possibly, if not probably, because the in- 

 vention of another and more effective weapon, or the acquired 

 knowledge of iron, caused them either to discard the ancient types 

 or to restrict themselves to one particular line. These agate, &c., 

 implements are similar to those dealt with further on in the 



* In the face of the Nooitgedacht and Barkly West finds, this conckision is 

 erroneous. 



f The dolerite implements are of a far more advanced type than the quartzite.
