ged scenery. Where, however, the overlying Glacial Conglom- 

 erate is only now in process of removal, the country retains the 

 rounded outlines characteristic of a glaciated landscape. 



Northern extension of the Glacial Conglomerate. 



I have recently met with good examples of the Glacial 

 Conglomerate much further to the north than any hitherto 

 described.* (Figures 1 and 2.) These are situated near the junc- 



tion of the Elands and Olifants Rivers, about 90 miles north of 

 the latitude of Johannesburg, and are interesting for the addi- 

 tional light they throw upon the northward extent of the coun- 

 try subjected to glacial action in early Karroo times. 



EXPLANATION OF FIGURES. 



Figure 1. — Glacial conglomerate near the junction of the Elands and 

 Olifants Rivers, Transvaal (75 miles NE. of Pretoria). 



Figure 2. — Weathered-out Glacial conglomerate, same locality. The 

 figure stands upon grits of the upper Karroo formation. 



Figure 3. — Glaciated surface. Elands River Valley (25 miles E. of Pre- 

 toria). 



Figures 4 and 5. — Glaciated surfaces north of Balmoral (50 miles E. of 

 Pretoria). 



The striated rocks are red quartzitic sandstones of the Waterberg Series.
