tion than the Table Mountain sandstone, a mistake that 

 led to the identification of the Bokkeveld and Malmes- 

 bury beds on the one hand and of the Table Mountain 

 and Witteberg series on the other. This unfortunate 

 confusion which is not met with in the maps or writings 

 of men who had a considerable personal knowledge of 

 the rocks concerned, such as Bain, Wyley and Dunn, 

 did much to obscure the interpretation of the structure 

 of the Colony. The work of the Survey has clearly de- 

 monstrated the correctness of Bain's view of the super- 

 position of the Bokkeveld on the Table Mountain series, 

 and the extension of the Witteberg series over wide 

 areas in the south-west, which were indeed made plain 

 by Wyley l and Dunn. 2 The three members of the 

 Cape system have now been so frequently traversed and 

 mapped between the Cederbergen and Uitenhage by the 

 geologists of the Geological Commission, 3 that there can 

 no longer be any doubt as to their relationship to one 

 another. 



1. THE TABLE MOUNTAIN SEKIES. 



This group of rocks forms the most conspicuous 

 features in Cape Colony. Table Mountain itself, rising 

 3,553 feet above the sea, is visible long before the ship 

 that brings the new-comer to South Africa reaches 

 Table Bay, and on the mountain several characteristics
