252 TSETSE IN UGANDA PEOTECTORATE. 



" Flies of the genus Glossina (a genus of which the 

 Tse-tse is a member) exist in the Uganda Protectorate. 

 They have been caught there by Mr. Jackson and myself, 

 not to mention many other collectors. But either the 

 true Tse-tse is absent from all parts of the Protectorate 

 or it is unable to obtain there the germs of fever which 

 it is the agent in introducing to the blood of horses, 

 cattle, and other beasts. This is a very fortunate cir- 

 cumstance, as it removes a serious hindrance in the way 

 of rearing live-stock and developing transport" (pp. 413- 

 414).

Tsetse-fly near the Kafue Biver, 1900. — Natives state 

 that the virulence of the bite of the fly has greatly diminished 

 since the extermination 0/ the buffalo by rinderpest. 



" It was not far from here [near the Kafue River, 

 about ninety miles above its confluence with the Zambesi] 

 that we sustained our first losses from the Tsetse-fly ; 

 sixteen donkeys and two horses fell victims to this scourge 

 of the country in the nine months of the expedition. 

 Livingstone thought that donkeys were immune from the 

 evil effects of the fly's bite, but this has long since been 

 disproved; the natives, however, state that since the 

 rinderpest exterminated the buflalo the tsetse has lost 

 much of its venom, and it does indeed seem to be less 

 virulent than formerly, as a horse lives now for three 

 weeks after a bite, whereas in former times it died a few 

 days afterwards."
