262 THE ROGGEVELD SHEETS 



beds, having passed diagonally through a thickness of 

 about 1,000 feet of strata in the course of sixty miles. 

 The lowest sheet forms the foothills of the Eoggeveld ; 

 outliers of it cap the Guap Mountain and Klip Kug Kop. 

 An offshoot from the lowest sheet runs along the foot 

 of the Roggeveld escarpment as far as the Rhenoster 

 River, a distance of fifty miles ; a second offshoot, at 

 a higher level, follows the first one for about the same 

 distance. A fourth sheet is connected with the third at 

 Roode Fontein on the edge of the Roggeveld, and in 

 addition to forming the edge of the escarpment for many 

 miles to the south of that place, covers a wide extent of 

 country to the north round Kreits Berg (Zand Kop), 

 Roep-mij-niet and Hantam, as well as a great tract to 

 the east. 



There appears to be no direct connection of the 

 Roggeveld sheets with those to the north-east in the 

 vicinity of Sutherland. The latter are the continua- 

 tions of a sheet which forms the summit of the western 

 Nieuweveld, where it drops gradually to the level of the 

 northern part of the Gouph ; it has thus been traced be- 

 tween points of 100 miles apart. 



East of the Tafel Berg, that fine flat-topped mountain 

 with such gracefully shaped slopes below the 400 foot 

 kranz of columnar dolerite, which can be seen together 

 with its neighbour, Spitz Kop, from the railway beyond 

 Prince Albert Road, the Nieuweveld summits are formed 

 by outliers of sheets that occupy wide stretches of 

 country behind the escarpment (Plate XVI.). Some of 

 the sheets appear as continuous outcrops, usually in the 

 form of cliffs 100 to 400 feet high, for about twenty
