Though ill with fever both times, he was able to conquer disease sufficiently to satisfy himself that this little lake, Dilolo, four thousand feet above the sea level, is located exactly on the watershed between the Atlantic and Indian Oceans, and distributes its contents impartially between the two seas. A drop of rain blown by the wind to the one or the other end of the lake may re-enforce the tumbling floods that roar through the channels of the Congo and rush sixty miles out into the salt waters of the Atlantic, or may make with the Zambesi the dizzy leap through the great Victoria Falls and mingle with the Indian ocean. No similar phenomenon is known anywhere. Lake Kivo may form a corresponding band of union between the Congo and the Nile, but this we do not know. Apart from the eccentric double part it plays, the physical features of Dilolo are tame and ordinary enough. It has, of course, hippopotami and crocodiles as every water in Central Africa has, and its banks are fringed with marshes covered with profuse growth of rushes, cane, papyrus, and reeds. Around it stretch wide plains, limitless as the sea, on which for many months of the year the stagnant waters rest, balancing themselves, as it were, between the two sides of a continent, unable to make up their mind whether to favor the east coast or the west with their tribute. No trees break the horizon. The lands in the fens bear only a low growth of shrub, and the landscape is dismal and monotonous in the extreme. “Dilolo means despair,” and the dwellers near it tell a story curiously resembling the tale of the “Cities of the plain,” and the tradition handed down regarding some of the lakes in Central Asia, of how a venerable wanderer came to this spot near evening and begged for the charity of shelter and food, how the churlish inhabitants mocked his petition, with the exception of one poor man who gave the stranger a nook by his fire and the best his hut afforded, and how after a terrible night of tempest and lightning the hospitable villager found his guest gone and the site of his neighbor’s dwellings occupied by a lake. When the rains have ceased and the hot sun has dried up the moisture the outlook is more cheerful. A bright golden band of flowers of every shade of yellow stretches across the path, then succeeds a stripe of blue, varying from the lightest tint to purple, and so band follows band with the regularity of the stripes on a zebra.
