236 TSETSE ON LAKE EUDOLPH. 



but, when once the point of the Jambeni hills is weathered, 

 the country becomes more open and the grass less rank, 

 and from there onward it is healthy for them " (pp. 161-

December, 1895. On the eastern shore of Lake Budolph, 

 near the northern end. — " Another frequent and disagree- 

 able accompaniment of abundant game was a fly, two 

 specimens of which I caught, that I have always taken 

 for the female of the ' Tetse,' though in this I may be in 

 error. It is larger than the typical one and of a uniform 

 brownish colour with no markings, but in other respects 

 exactly similar both as to appearance and habits,* and I 

 have always before noticed it associated with the smaller 

 striped variety, though I saw none of the latter kind here. 

 Whether this kind is poisonous or not I am not sure. My 

 donkeys never suffered from having passed here; but then 

 they can stand a feio ' fly,' though where the ' Tetse ' is 

 numerous they soon succumb " (p. 282).

On the left bank of the Njoko River, near its confluence 

 tvith the Zambesi, August, 1895. — *' Many of the northern 

 tributaries of the Zambesi, unlike the dry sand rivers 

 of South Africa, flow through wide alluvial valleys, occa- 

 sionally quite 1000 yards in width. These valleys, though 

 dry in winter, become swampy in the rainy season. The 

 rich soil produces excellent cattle pasture, capable of 

 sustaining vast herds in those districts which are not 

 infested by the Tsetse-fly. This cruel little pest is parti- 

 cularly numerous on the lower reaches of the Njoko 

 River. I The excessive attention they paid to the back of 

 my neck resulted in boil-like lumps, which at one time 

 threatened to give much pain and inconvenience ; but zinc 

 ointment and a protecting handkerchief proved a rapid 

 and efficacious remedy. 



* [The fly here alluded to is obviously Glossina fusca, Walker, one of 

 the two large species of Tsetse-flies : the other largo species is Glossina 

 lonrjipennis, Corti, which is found in Somaliland. — E. E. A.]
