Usongora is the great salt field whence all the surrounding countries obtain their salt. It is, from all accounts, a very land of wonders; but the traveller desirous of exploring it should have a thousand Sniders to protect him--for the natives, like those of Ankori, care for nothing but milk and goatskins. Among the wonders credited to it are a mountain emitting “fire and stones,” a salt lake of considerable extent, several hills of rock salt, a large plain encrusted thickly with salt and alkali, a breed of very large dogs of extraordinary ferocity, and a race of such long-legged natives that ordinary mortals regard them with surprise and awe. The Waganda, who have invaded their country for the sake of booty, ascribe a cool courage to them, against which all their numbers and well-known expertness with shield and spear were of little avail. They are, besides, extremely clannish, and allow none of their tribe to intermarry with strangers, and their diet consists solely of milk. Their sole occupation consists in watching their cows, of which they have an immense number; and it was to capture some of these herds that the Emperor of Uganda sent one hundred thousand men, under his Prime Minister, to Usongora. The expedition was successful, for by all accounts the Waganda returned to their country with about twenty thousand; but so dearly were they paid for with the loss of human life, that it is doubtful whether such a raid will again be attempted to Usongora. Upon arriving at Karagwe, Stanley was enabled through the kindness of the King, Rumanika, to explore the frontier of Karagwe as far north as Mpororo, and south as Ugufu. The yacht _Lady Alice_ was conveyed to Speke’s Lake Windermere, and the sections screwed together, and after circumnavigating the lake, they entered the Kagera River, when it almost immediately flashed across Stanley’s mind that he had made another grand discovery--that he had discovered, in fact, the true parent of the Victoria Nile. A glance at Speke’s map will show the reader that he calls the river the Kitangule River, and that he has two tributaries running to it, called respectively the Luchuro and the Ingezi. Speke, so wonderfully correct, with a mind which grasped geographical knowledge with great acuteness, and arranged the details with clever precision and accuracy, Stanley thinks is seriously in error in calling this noble river Kitangule. Neither Waganda nor Wanyamba know it by that name; but they all know the Kagera River, which flows near Kitangule. From its mouth to Wrundi it is known by the natives on both banks as the Kagera River. The Luchuro, or rather Lukaro, means “higher up,” but is no name of any river.
