ERKOWIT

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 
43i inches.
