liaunts arc easily discoverable, but generally difficult of 
access, and not safe to approach. The torrents of water 
rushing down the steep sides of the high stratified mountains, 
frequently carry with them the loose materials, and leave a 
succession of caverns, of which the Bosjesman pitches on the 
highest, for his temporary habitation, not only as the means 
of removing him farther from the danger of a surprise, but 
as affording him at the same time the command of a greater 
extent of country. 
In one of these retreats we discovered their recent traces. 
The fires were scarcely extinguished, and the grass on which 
they had slept was not yet withered. On the smooth sides of 
the cavern were drawings of several animals that had been 
made from time to time by these savages. Many of them 
were caricatures ; but others were too Avell executed not to ar- 
rest our attention. The different antelopes, that were there 
delineated, had each their character so well discriminated, 
tliat the originals, from whence the representations had been 
taken, could, without any difficulty, be ascertained. Among 
the numerous animals that were drawn, the figure of a zebra 
was remarkably well executed ; all the marks and cliaracters 
of this animal were accurately represented, and the propor- 
tions seemingly correct. The force and spirit of drawings, 
which are given by bold touches judiciously applied, and by the 
effect of light and shadow, could not be expected from sa- 
vages ; but for accuracy of outline and correctness of the dif- 
ferent parts, worse drawings than that of the zebra have 
passed through the engravers hands. The materials with 
which they had been executed were charcoal, pipe-clay, and
