THE CAPE SYSTEM 141 



the Bokkeveld "^ Other clean-cut sections through the 

 junction may be seen lower down the Gamka (Gouritz) 

 Eiver in the Pogha Hills and near the new road to 

 Cloete's Pass, and at the north end of Meiring's Poort. 



The Bokkeveld beds are well exposed in the Cold and 

 Warm Bokkeveld s, in the Hex Kiver Valley especially 

 between De Dooms and Klein Straat stations, and 

 along the northern flank of the Zwartebergen. They 

 occupy wide areas in the Ladismith Karroo and south of 

 the Langebergen ; but south of the Zwartebergen they 

 have been greatly changed by the movements which 

 gave rise to those mountains, and are much cleaved. 

 They have only been found within the folded belt south 

 and west of the Karroo. No outliers have been met 

 with in the Pre-Cape region of the west and north, and 

 in Pondoland they have been removed by denuda- 

 tion, if they were ever deposited there. There can be 

 little doubt that they once overlay the sandstone of 

 Table Mountain, although the nearest outcrop is at 

 Grabouw, east of Hottentot's Holland, about thirty-six 

 miles in a straight line from Table Mountain. 



Where typically developed the Bokkeveld beds con- 

 sist of shales and sandstone arranged in a definite order, 

 although the details vary from one locality to another. 

 The lowest division consists of shales and thin sand- 

 stones about 300 feet thick and contains many fossils, 

 amongst which are trilobites belonging to the genera 

 Phacops and Homalonotus ; brachiopods of the genera 

 Leptoccelia, Spirifer, Chonetes and Orthothetes ; Orthoceras,

 the Bokkeveld beds will be found in that Eeport.
