16 LIVINGSTONE'S LAST JOURNALS. [Chap. I. 



liitlier from Manyuema my goods and fresh men from Zan- 

 zibar will have arrived, and I shall be better able to judge 

 as to the course to be pursued after that. Mokamba is about 

 twenty miles beyond Uvira; the scene of Moeneghere's 

 defeat is ten miles beyond Mokamba ; so the unexplored 

 part cannot be over sixty miles, say thirty if we take 

 Baker's estimate of the southing of his water to be near 

 the truth. 



Salem or Palamotto told me that he was sent for by a 

 headman near to this to fight his brother for him : he went 

 and demanded prepayment ; then the brother sent him three 

 tusks to refrain : Salem took them and came home. The 

 Africans have had hard measures meted out to them in the 

 world's history! 



28th June. — The current in Tanganyika is well marked 

 when the lighter-coloured water of a river flows in and 

 does not at once mix — the Luishe at XJjiji is a good example, 

 and it shows by large light greenish patches on the sur- 

 face a current of nearly a mile an hour north. It begins 

 to flow about February, and continues running north till 

 November or December. Evaporation on 300 miles of the 

 south is then at its strongest, and water begins to flow gently 

 south till arrested by the flood of the great rains there, 

 which takes place in February and March. There is, it 

 seems, a reflux for about three months in each year, flow and 

 reflow being the effect of the rains and evaporation on a 

 lacustrine river of some three hundred miles in length lying 

 south of the equator. The flow northwards I have myself 

 observed, that again southwards rests on native testimony, 

 and it was elicited from the Arabs by pointing out the 

 northern current: they attributed the southern current to 

 the effect of the wind, which they say then blows south. 

 Being cooled by the rains, it comes south into the hot 

 valley of this great Biverein Lake, or lacustrine river.
