ra; 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, 1869._--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 Ujiji is a good example, and it shows by large light greenish
patches on the surface 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 Riverein Lake, or
lacustrine river.

In going to Moenekuss, the paramount chief of the Manyuema, forty days
are required. The headmen of trading parties remain with this chief (who
is said by all to be a very good man), and send their people out in all
directions to trade. Moenemogaia says that in going due north from
Moenekuss they come to a large river, the Robumba, which flows into and
is the Luama, and that this again joins the Lualaba, which retains its
name after flowing with the Lufira and Lofu into the still unvisited
Lake S.S.W. of this: it goes thence due north, probably into Mr. Baker's
part of the eastern branch of the Nile. When I have gone as far north
along Lualaba as I can this year, I shall be able to judge as to the
course I ought to take after receiving my goods and men from Zanzibar,
and may the Highest
