The hyraxes leave their burrows or ledges towards three in the afternoon and 

 probably feed throughout the night. At eight in the morning and slightly later 

 they bask on their ledges, but are always watchful. After ten o'clock they are not 

 seen out. 



These animals are very shy and make a low barking (somewhat guttural) sound 

 at the approach of danger. They run swiftly along and upward on the strongly 

 inclined rocks where it would be impossible for any man to get a foothold. 



These hyraxes evidently give birth to their young the end of December or the 

 beginning of January. 1 



The hyraxes nibble off the fine grass growing between the rocks. This grass 

 when chewed or rubbed has an aromatic smell. Their stomachs contain, chiefly, this 

 grass finely chewed up. There are many other plants fed upon, also the ordinary grass, 

 especially that sprouting freshly after being burned out in the beginning of the dry 

 season. The natives assured me that the hyraxes are often found far from their 

 rocks, feeding on young sprouting grass.

1 A conclusion scarcely justified by observations made over only 7 months of the year, and on 

 few adult females.
