of Table Mountain Sandstone, which is not seen in the southern 

 hills. It is quite clear that the material of which these hills are 

 composed has been derived from at least three sources ; and, from 

 a careful examination, it appears certain that the gravels are 

 successively newer towards the north. Pig. 2 shows the interpre- 

 tation of the section which I adopted, after a critical examination in 

 company with Dr. Melle, of Robertson, who is well acquainted with 

 the geology of the neighbourhood. Of course, in this section the 

 exact position of the fault is hypothetical, but compass-bearings of 

 points where it is known give the general position with fair accuracy. 

 It must come somewhere under the gravel-ridge marked G, which 

 obviously overlies the Enon Conglomerate, and is overlain in turn 

 by the coarse breccia B.

I conclude, therefore, that the Enon Conglomerate does not 

 extend over the line of the fault on to the Malmesbury Beds, but 

 is cut off by the fault on the northern side. 



It is of interest to note that the Enon Beds of this area are not 

 wholly conglomeratic ; but near Klaas Voogds Station there is a 

 development of fine grey or white sandstone, which shows some 

 approximation to the more normal marine Cretaceous deposits of 

 the Uitenhage district. This is probably the westernmost point to 

 which the marine Uitenhage facies has been traced. Unfortunately, 

 no fossils were found here. 



X. The Ashton District. 1 



Ashton Station, on the New Cape Central Railway, lies about 

 12 miles east of Robertson, and from it an important road leads 

 through Kogmans Kloof to the town of Montagu, which lies on 

 the other side of the Langebergen. The general character of the 

 country is very similar to what is seen farther west, but on the 

 whole the topography is simpler. 



The belt of Malmesbury rocks is here much narrower, being not
