On ascending the hill we kept finding palaeoliths, made mostly of 

 a more quartzitic sandstone than the usual Stellenbosch type — a 

 sandstone that, we found later, occurs only some 4 or 5 miles from 

 the spot. 



Well-nigh at the top {B in text-figure) were palaeoliths, some 

 jammed into the interstices of the rocks, which are perforated and 

 vermiculated by sand action in a very singular manner. Here and

there also we found the small Cape Flat type of flakes and pot- 

 sherds. 



More numerous than the large implements, there occurred at that 

 altitude, some 400 feet from the first find, large detaching hammers 

 of the type of Fig. 75. Their weight had offered probably more 

 resistance to their removal to a lower level. 



Proceeding along the line of the hill, we did not find any boucher, 

 but at a lower level we met instead with many large hammers or 

 nuclei similar to those found at the higher level. Fig. 75 of PI. XI., 

 picked up there, represents a moderately-sized one. 



Arrested no longer by the layer of ironstone, which is not to be 

 found there, they have by the pulsating effect of the removal of the 

 sand reached the floor of the dune, and have in several instances
