This subsidencecaused great alarm to the natives, who feared the white wizards might emptythe whole lake by throwing medicines into Lu-Kuga. See, said a chief toM. Giraud, how they cross the lake and the water goes with them.

According to the latest measurements, Tanganyika stands over 2,600 feetabove the sea, which would give the emissary a fall of about 7 feet per mile,during its course of 120 miles to the Congo. Throughout its upper course, whichalone has hitherto been surveyed, the current is very rapid, without, however,forming any cascades. Its foaming waters flow through a charming valleybetween wooded hills, rising on both sides from 800 to 2,000 feet above the THE MIDDLE CONGO. 425 surroundiug grassy plains, studded here and there witli clumps of tivcs midroamed over by herds of buffaloes aud antelopes.
