18J: MOVEMENTS OF GLOSSINA MORSITANS IN THE LUNDAZI DISTRICT. 



My district is bounded by the Luangwa on the west, the Wira and 

 Kamimbi to the north, Nyasaland on the east, and by Fort Jameson District 

 (13° 5') on the south. 



The old Nawalia station on the Nyamadzi River, west o£ the Luangwa 

 (about 12° 25' S.), was free from fly until 1904 ; there was always a small 

 herd of Government cattle there. About the middle of 1904 there was an 

 alarm of tsetse having spread into the neighbourhood, and the cattle were 

 sent away. In 1905-6 I occasionally saw a specimen in the police lines, 

 but never one actually at my residence. I am told by Europeans that now 

 the old lines (which have become a native village) are full of fly, and there 

 are usually some also about my old quarters. 



In the south end of my district the fly has spread a good deal, up the 

 Lukuzi River ; it first appeared about Masumba's in 1904 (lOf miles up- 

 stream from Kambwiri's) ; in 1906-7 it appeared at Chinunda''s_, and the 

 cattle there died ; and last year I saw it for about 5 or 6 miles along the 

 road from Chinunda^s towards Fort Jameson. 



Mr. Forsyth tells me that the natives about the Luwumbu River, where 

 he has been hunting, say that before the rinderpest (in the early ''90's'') 

 game was very abundant indeed, especially buflalo, and there were great 

 quantities of fly ; but after the rinderpest there was almost no game at all, 

 and the fly disappeared at once ; from that time to this the game has been 

 coming in again and constantly increasing, and the fly has spread every 

 year. This is exactly what the natives round Nawalia told me in 1904-5 ; 

 they especially mentioned the amount of wildebeeste, and spoke of the fly 

 as a plague even in the villages. 



The Rev. D. Fraser, of Loudon, has told me that my northernmost green 

 patch was a fly-free country, with several small herds of cattle, about 

 10 years ago. He also tells me that, according to the natives, the whole 

 course of the Rukuru River (parallel with my eastern border) was fly-infested 

 about 20 or 25 years ago ; it is now one line of cattle-owning villages. He 

 does not know whether the change coincided with the rinderpest. There is 

 little or no large game along the Rukuru^ as the Angoni are constant and 

 energetic hunters.
