ERKOWIT 383 



camelry from Tokar. The plan, however, had to be 

 abandoned owing to an unanticipated circumstance. A 

 biting fly of seroot type, but even more vicious, at this 

 season invades the hills on such scale as to drive man and 

 beast pell-mell to lower regions. Not even a camel can 

 withstand the attack of these flying terrors. Two friends 

 (Messrs Gerald Legge and Wormald) had completed an 

 expedition to the Karora hills just in time ; they found 

 plenty of ibex, though good heads distinctly scarce, and 

 were lucky in securing one specially fine specimen of 

 43! inches.
