164 THE WITTEBERG BEDS 



Kouga) hills are in this area. The axis of the main 

 anticline of the Wittebergen disappears eastwards south 

 of Laingsburg, where a long syncline of the Dwyka 

 series lies south of the eastern part of the range. The 

 Witteberg beds pass round the western end of the Dwyka 

 syncline into Eland's Berg, which disappears eastwards 

 in a similar manner to the Wittebergen, but the beds 

 pass round another westerly rising Dwyka syncline into 

 the long range of foothills north of the Zwartebergen, 

 and extend far to the east, certainly as far as Willow- 

 more ; they reappear from under a syncline of the 

 Dwyka series in the GJ-root Kiver and Klein Winterhoek 

 ranges to the north. East of the Klein Winterhoek 

 Mountains the Witteberg beds form the Zuurbergen, 

 the hills near Commadagga, Botha's Hill and the hills 

 south of Grahamstown, and much of the country be- 

 tween Grahamstown and the coast. 



The Witteberg country in the IL astern Province is 

 much better covered with vegetation than that in the 

 west, chiefly on account of the greater rainfall, but pos- 

 sibly the eastern rocks are somewhat more argillaceous 

 and less quartzitic than the western, and therefore give 

 rise to better soils. Whether the Witteberg series as a 

 whole becomes finer grained towards the east is still 

 uncertain, for it has not been closely examined in that 

 part of the country. 



To the south of the Langebergen and east of Robert- 

 son the Witteberg beds are distinctly less quartzose and 

 coarse grained than to the north of that range ; a change 

 takes place in them similar to that noted in the Bokke- 

 veld series, as they are followed southward p. It hag
