that the Cretaceous rocks were deposited at a height above their 

 present level equal to the total throw of the fault. He had no 

 doubt that a large part of the movement was of earlier date, and 

 considered that a post-Cretaceous movement of 2000 or 3000 feet 

 was sufficient to account for the phenomenon. He certainly did 

 not believe that the Cretaceous rocks ever extended over the Karroo, 

 and regarded the Enon Conglomerate as a torrential deposit formed 

 at the foot of a mountain-escarpment, probably a fault-scarp. He 

 much regretted that he had had little opportunity of discussing 

 the matter with Dr. Eogers, and awaited with great interest the 

 opinion of South African geologists on the paper. In reply to 

 Dr. Evans, he stated that conglomerates do exist to the north of the 

 fault, but these are of quite different character and undoubtedly 

 recent. In conclusion, the Author admitted that the view put 

 forward by the Cape geologists offered an easier interpretation, but 

 he did not believe it to be correct.
