But the ores of thefe mountams, however abundant, and how- 
ever rich, are of no great value on account of the total want of 
every kind of fuel to fmelt them, as well as of their very great 
diftance from the Cape, and from there being neither bay nor ri- 
ver where they could be put on board of coafting vefTeis. In the 
Khamiefberg is alfo found, in large blocks, that beautiful fpecies

tries, are the fummit of a long extended Table Mountain, whofe 
weftern front rifes out of the Karroo plains behind the Bokke- 
veld, almoft perpendicularly, to the height of two or three 
thoufand feet. Stretching to the eaftward this fummit becomes 
more broken into inequalities of furface, and rifes at length into 
the mountains of Nieuweld^ the Camdeboo, and the Sneuwberg,. 
which may be confidered as one extended chain. The great 
elevation of the Roggeveld, and its being furrounded by Karroo 
plains, make the temperature in winter fo cold, that for four 
months in the year the inhabitants are under the neceffity of 
delcending to the feet of the mountains with their horfes, cattle,, 
and flieep. The ftrongeft and largeft breed of horfes in the 
whole colony is that of the Roggeveld.
