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.
