A SPRING EVBRY TWO MILES.

The prevailing winds on the watershed are from the 
southeast. This is easily observed by the direction of the 
branches, and the humidity of the climate is apparent in 
the numbers of lichens which make the upland forest look 
like the mangrove swamps on the coast. 
In passing over sixty miles of latitude I waded thirty- 
two primary sources from calf to waist deep, and requiring 
from twenty minutes to an hour and a quarter to cross 
stream and sponge. This would give about one source to 
every two miles. 
A Suaheli friend in passing along part of the Lake 
Bangwcolo during six days counted twenty-two from thigh 
to waist deep. This lake is on the watershed, for the vil- 
lage at which I observed on its northwest shore was a few 
seconds into eleven degrees south, and its southern shores 
and springs and rivulets arc certainly in twelve degrees 
south. I tried to cross it in order to measure the breadth 
accurately. The first stage to an inhabited island was 
about twenty-four miles. From the highest point here the 
tops of the trees, evidently lifted by the mirage, could lie 
seen on the second stage and the third stage ; the mainland 
Was seen to be as far as this beyond it. But my canoemen 
had stolen the canoe, and got a hint that the real owners 
were in pursuit and got into a flurry to return home. 
“ They would come back for me in a few days truly,” but I 
had only my coverlet left to hire another craft if they 
should leave me in this wide expanse of water, and being 
4000 feet above the sea it was very cold ; so I returned. 
The length of this lake is, at a very moderate estimate, 
150 miles. It gives forth a large body' of water in the 
Luapula ; yet lakes are in no sense sources, for no large 
river begins in a lake ; but this and others serve an im- 
portant purpose in the phenomena of the Nile. It is one 
largo lake, and unlike the Okara, which, according to Sua- 
heli, who travelled long in our company, is three or four 
lakes run into one huge Victoria Nyanza, gives out a large 
river which, on departing out of Moero, is still larger.
