98 THE ASBESTOS HILLS 



same may be the case on the farm Folmink near the 

 Orange Kiver. 



The Lower Griqua Town beds form the longest range 

 of hills in the north of the Colony. Starting from the 

 Orange River near Prieska under the name of the 

 Asbestos Hills it has a north-north-east course at first, 

 but turns more and more to the north towards Daniel's 

 Kuil and then to the north-north-west, where it is 

 crossed by the Bechuanaland fence near the Gakarusa 

 beacon ; it maintains this trend past Kuruman (under 

 the name of the Kuruman hills) to the poort of the 

 Kuruman Kiver, where it again turns north; beyond 

 the place where it is cut through by the Mashowing it 

 turns to the north-north-east again, and continues in 

 that direction past Heuning Vlei. Though not an un- 

 broken range, for it is crossed by the rivers named as 

 well as by a tract of low ground near Daniel's Kuil, it is 

 a distinct feature for some 300 miles, and even where 

 the rocks are for miles together hidden under sand, as 

 is the case north of the Mashowing, there is a belt of 

 rising ground or " bult " to mark its position. It rises 

 to its greatest height near the Bechuanaland fence, 

 where the Gakarusa beacon stands 6,069 feet above 

 sea level. Beyond Heuning Vlei the strike of the 

 Lower Griqua Town beds turns more and more towards 

 the east ; but the rocks only appear in a few low hills 

 projecting from the sand ; they terminate at the Molopo 

 near the north-western corner of the Mafeking Division. 

 This long sinuous course indicates the changes of 

 strike of the Transvaal formation in Cape Colony more 

 clearly than any other feature.
