Draper, D. Letter on " The Age of the Band Beds." Geol. Mag., 

 New Series, Dec. iv., vol. v., No. 3, 1898, p. 141. 



The writer corrects a statement made by Mr. Gibson in Geol. 



Mag., 1895, p. 549, that the writer found fossils in the dolomite 



associated with the Gats Band Beds. The writer is unaware 



that fossils have been found in this rock.

Wendeborn, B. A. " Storungen der Schichten zwischen Pretoria 

 und Vereeniging im Transvaal und die darans resultirenden 

 Schlusse liber den Verbleib der goldhaltigen Conglomerate." 

 Zeitschrift fur praktische Geologie, Sept., 1897, S. 305-311. 



The paper begins with a short sketch of the succession of 

 the Transvaal formations after Schenk. The relation of the 

 sedimentary rocks to the granite between Pretoria and Johan- 

 nesburg is dealt with, the steep dip of the conglomerates 

 south of the granite mass, and the gradual decrease of dip 

 being especially emphasised. As the folds run east and west 

 the pressure must have been in a north and south direction, and 

 more effective south of the granite than further north. 



The structure of the country between Johannesburg and 

 Pretoria is shown by means of a section to consist of a faulted 

 and denuded anticline — the granite occupying the centre, and 

 the northern fault having a much greater downthrow than that 

 on the south. The author reckons that north of the granite 

 towards Pretoria, the South Beef of the Main Beef Series, lies 

 at a depth of 15,500 feet, and that, therefore, it will be im- 

 possible to attempt to mine this northern portion of the gold- 

 bearing conglomerates. 



The numerous " reefs " of small extent which overlie the 

 main gold-bearing series have been probably formed, at least in 

 part, from the debris of the denuded anticline, and as all the 

 later sedimentary series, even the coal-bearing formation, 

 contain traces of gold, a similar origin for these is likely.
