white surfaces. I have not observed any natural enemies, nor have I seen 

 the {\y drinking. 



Cattle are kept in large herds over the whole of the country above 

 described, and I have observed them being bitten when being watered at 

 many of the rivers. The cattle infected with Nagana (?) at the Ponga are 

 said to have come from the Chungu, less than a mile distant, where there are 

 large herds apparently quite healthy, though I have seen them being bitten 

 by G.fusca. 



There is a history of all the cattle having died off in two places, at one 

 of which, Katumbi on the Kaporo River, no attempt has since been made to 

 keep them ; at the other, Mwaisandoro, on the Makeye, there are at present 

 a number of cattle, apparently healthy. G.fusca was found at both places. 



A few isolated cases of Sleeping Sickness have been found in Nyasaland, 

 one in this District, but none in the part described above.
