 moorland at the summit of the Aberdare Range. The spot was 

 within a stone's throw of the Safari camp at an elevation of approxi-

 broad flattened summit which extends in a North and South direc- 

 tion in a series of rolling downs for many miles. The downs are 

 clothed everywhere by a thick carpet of alpine shrubs, chiefly various 

 species of Alchemilla, interspersed with a few tussocks of rank grass, 

 and widely scattered thickets of heather bushes.

 Alchemallse shrubs grow so densely that travel over the moorland 

 is very much like wading through soft snow-drifts. The duikers do 

 not live in the open moorland, but frequent the heather thickets 

 where the ground is firmer. At night, however, they wander about 

 over these boggy and shrubby moors, upon the shrubs of which they
