Propounds the theory that the gold in the Banket is deposited 

 from solution, gold salt being the trichloride and the reducing 

 agent organic matter, and sulphuretted hydrogen obtained from 

 the decomposition of it or by the action of bacteria elaborating 

 the gas. The small percentage of phosphoric acid in the 

 analysis of Banket ores proves the former presence of animal 

 matter. The pebbles of quartz were deposited from rapid 

 streams, and the interstices being comparatively free from 

 currents allowed the deposition of gold. The coarse reefs are 

 poor. The depth of the ocean in which the Banket was formed 

 was 23,000 feet. E. H. L. S.

The dolomites north and south of Johannesburg at Six Mile 

 Spruit and Klip Eiver can be traced to the farm Bosch-pan, 

 where the two series meet. Below the dolomite is the Black 

 Beef series resting unconformably on older quartzites and 

 conglomerates. The Hospital Hill States can also be traced 

 westward to Witkop in the Vaal Biver where the Black Beef 

 series crosses over into the Orange Free State, so that this 

 Beef is continuous from Klip Biver to the Vaal, displaced only 

 by a fault on the farm Oog van Wonderfontein. Near Klerks- 

 dorp the Main Beef series is well known ; on the commonage 

 at Klerksdorp conglomerates similar to the Elsburg series occur 

 overlaid by an amygdaloidal diabase. The conglomerates on 

 the west are repeatedly folded. E. H. L. S.
