our stalks after oryx and zebra were spoilt by my noisy 
camel-men. At length we reached the Bun Feroli again,

of oryx ; but as the water about here had nearly dried 
up, the zebra had shifted their quarters. On the way I 
noticed very curious clouds of sand, sent up sometimes to a 
height of 400 feet into the air by a whirlwind. This sand- 
cloud would often remain at this immense height in one 
huge pillar, which would slowly drift along, not dispersing 
for several minutes. The great quantity of dust was caused 
by the huge herd of camels which had lately been driven to 
and from the wells at Gonsali.
