Now began a journey full of thrilling events. Almost every day brought its danger from storm, shoal, animal or hostile natives. For weeks the shores of the Nyanza stretched on, promontory behind promontory, and still the tired mariners toiled along the margin of the unknown lands on their lee, and out and in among the numerous islands. From the starting point round the eastern shore, the coast shows a succession of bold headland and deep bay, at the head of which is generally a river draining the highlands behind. Sometimes a dark mountain mass, covered with wood, overhangs the waters, rising abruptly to a height of three thousand feet or more; and then again there will intervene between the hills and the lake an open plain, grazed over by herds of zebras, antelopes, and giraffes. There is great diversity also in the islands. Many of them are bare masses of rock, supporting no green blade; others are swathed to the summit in masses of rank intertwisted vegetation that excludes the perpendicular rays of the sun. Some of the smallest are highly cultivated, and occupied by a dense population; one or two of the largest, such as Ugingo, betray no sign of human beings inhabiting their dismal shades. Generally the region is rocky, broken, hilly, and intensely tropical in character. Behind the coast ranges absolutely nothing is known beyond a few vague reports picked up from native sources. The rivers are not large, and it is not probable that they have their sources so far off as the great snowy range that runs down midway between the lake and the east coast of Africa. Some geographers have chosen to call this chain by the old name of “Mountains of the Moon,” throwing the old land mark from the southern borders of Sahara to a point quite south of the equator and at right angles with their former direction. Between the lake and these snow-capped mountains roam the Mdai, a fierce pastoral tribe that subsists by plundering its weaker neighbors. Stanley heard of hills that smoked in these ranges, and probably they contain active volcanoes. He also heard of the mythical Lake Baringo further north. This lake has appeared almost everywhere on African maps. If it is ever found, it may prove to be the reservoir of the Ashua, an important Nile tributary, after the stream leaves both Victoria and Albert Nyanza.
