A JOURNEY DOWN THE ROVUMA RTVER, PORTUGUESE EAST AFRICA. 45 



September — . Easterwoods camp by Rovuma liver. Flies crawl up trouser 

 tegs to the knee. Counti-y is fairly thickly covered with trees, but they are 

 leatless at this time of the year. No buffalo, but nswale (impala), water- 

 buck and kudu plentiful. Fly very numerous ; one caught in grass hut. 



October 14th. Eight miles east of Chualezi contluence (26). Dull day. Fly 

 caught in open native hut, thick bush all round ; Rovuma 100 yards away. 

 Fly plentiful when sun shining, scarce when dull. Game (waterbuck) 

 plentiful. 



October 17th. Fly not seen ; they stopped as soon as traces of waterbuck 

 disappeared. Country diiFerent — broken and stony, with thick shrubby 

 undergrowth, at present absolutely leafless and charred by fire. Day bright, 

 with steady breeze. 



October 18th. Hilly country close to the Rovuma, which clings to the hills and 

 flows in a deep rocky hollow. Elephant, eland, zebra, kudu and sable 

 country ; no waterbuck and no fly. 



October 19th. No fly till we arrived near the river, when one specimen seen at 

 the same time as were some waterbuck. Other game teems. 



October 20th. One fly seen. Eland and other game present. The fly was 

 found by the river — none were seen away from it, though conditions 

 favoured them. Perfect day. Country same as on the 18th October — 

 thickly covered with short leafless trees, sandy, and dry leaves under foot. 



October 21st. One fly seen in -the bwalo* of a big village on the Lusanjesi, 

 15 miles from camp of the 20th October. 



October 22nd. No fly seen. 



October 23rd. One fly seen in high lying land near the Lujenda-Rovuma 

 confluence. 



October 26th. No tsetse seen since Lujenda crossed. Country similar to that 

 previously met with in which fly swarmed, except perhaps that the bush is 

 more dense. Leafless undergrowth is the prevailing feature. 



October 28th. Saw one tsetse fly. Day sunny. Dense river undergrowth — 

 palms and green shrubs. 



October 29th. One fly caught in upland tree country ; trees mostly leafless. 

 Oribi and elephant the only inhabitants ; no water within about 10 miles. 

 A few other flies seen, though very scai'ce. Day very hot ; in afternoon 

 some clouds. 



October 30th to November 1st. No fly seen. 



Since the 2nd November no fly caught and no record kept. On one or two 



occasions however single specimens were seen near the river, in thick green 



country. Sun very hot in day time. Buffalo generally present inland from the 



river, to which they came down during the night to drink. The last of such 



specimens was seen at Palma on the coast. 



Fly were first seen at Chisindo, — 30 miles east of Lake Nyasa, and last, on the 



East Coast near the Rovuma mouth. There appeared to be few, if any, spots 



throughout the entire journey which fly did not inhabit.

 congregate. :
