192 KLOOF AND KARROO. 



to an opening, and here a most singular sight fell 

 upon my vision. Hitherto we had been so shut 

 in that the sun failed to penetrate between the 

 narrowing cliffs- except, probably, for a short while 

 as it passed immediately above them. 



" Suddenly, as the gorge widened on either hand, 

 a blaze of sunlight glowed and glistened on the 

 upright walls to the left hand of us. As I looked
