212 LIVINGSTONE'S LAST JOUKNALS. [Chap. VIII.. 



run. The Lokhopa, for instance, was asserted by all the 

 men at Moamba's to flow into Lokholu, and then into a 

 river going to Liemba, but a young wife of Moamba, who 

 seemed very intelligent, maintained that Lokhopa and 

 Lokholu went to the Chambeze ; I therefore put it down 

 thus. The streams which feed the Chambeze and the 

 Liemba overlap each other, and it would require a more 

 extensive survey than I can give to disentangle them. 



North of Moamba, on the Merenge, the slope begins to 

 Liemba. The Lofu rises in Chibue's country, and with its 

 tributaries we have long ridges of denudation, each some 

 500 or 600 feet high, and covered with green trees. The 

 valleys of denudation enclosed by these hill ranges guide 

 the streams towards Liemba or the four rivers which flow 

 into it. The country gradually becomes lower, warmer, and 

 tsetse and mosquitoes appear ; so at last we come to the 

 remarkable cup-shaped cavity in which Liemba reposes. 

 Several streams fall down the nearly perpendicular cliffs, 

 and form beautiful cascades. The lines of denudation are 

 continued, one range rising behind another as far as the 

 eye can reach to the north and east of Liemba, and pro- 

 bably the slope continues away down to Tanganyika. The 

 watershed extends westwards to beyond Casembe, and the 

 Luapula, or Chambeze, rises in the same parallels of lati- 

 tude as does the Lofu and the Lonzua. 



The Arabs inform me that between this and the sea, 

 about 200 miles distant, lies the country of the Wasango — 

 called Usango — a fair people, like Portuguese, and very 

 friendly to strangers. The Wasango possess plenty of 

 cattle : their chief is called Merdre.* They count this 

 twenty-five days, Avhile the distance thence to the sea at 

 Bagamoio is one month and twenty-five days — say 440 

 miles. Uchere is very far off northwards, but a man told 



* The men heard in 1873 that he had been killed.
