KLOOF AND KARROO. 



was surrounded by stupendous walls of the same 

 ruddy brown rock we had noticed in Paarl Kloof, 

 which here towered to a height of close on a 

 thousand feet. An inspection of these cliffs, which 

 sheered inwards from top to bottom, revealed the 

 fact previously imparted to me by Klaas, that no 

 living being could ever penetrate hither save by the 

 tunnel passage through which we had come. The

 gravel especially where it had been cleansed in 

 the shallow spruits and dongas by the action of rain
