[Illustration: RECEPTION OF THE CHIEF RUHINGI.] “This is one of the many things which he has yet to examine.” It thus appearing that the Rusizi is an affluent, not an effluent, of Tanganyika Lake, the expedition failed to sustain the explorer’s hypothesis, but added a useful item of geographical knowledge to the then existing stock. Nor does it follow that because the Rusizi flows into the Tanganyika, there is no river flowing out of it into that system of lakes which had before been discovered by the explorer, and of which the Chambesi--almost a system of rivers itself--is the largest affluent yet discovered. Should Dr. Livingstone’s hypothesis of an effluent from the west shore of Tanganyika Lake not be sustained, and its waters found to procure outlet by Lake Nyassa and the Zambesi, his future discoveries will in all probability show a similar formation of the continent in east central Africa to that which he discovered to be the fact when he explored Lake Dilolo in the land of the Balonda. The explorers remained in Ujiji until after “merry Christmas,” both engaged much of the time in writing accounts of their explorations, which have appeared or will yet appear in this volume. Meanwhile, they had determined to make a journey together to Unyanyembe. This journey is described in telegraphic brevity: KWIHARA, UNYANYEMBE, February 21, 1872. After spending Christmas at Ujiji Dr. Livingstone, escorted by the NEW YORK HERALD Expedition, composed of forty Wanguana soldiers, well armed, left for Unyanyembe on the 26th of December, 1871. In order to arrive safely, untroubled by wars and avaricious tribes, we sketched out a road to Unyanyembe, thus:-- Seven days by water south to Urimba. Ten days across the uninhabited forests of Kawendi. Twenty days through Unkonongo, direct east. Twelve days north through Unkonongo. Thence five days into Unyanyembe, where we arrived without adventure of any kind, except killing zebras, buffaloes, and giraffes, after fifty-four days’ travel. The expedition suffered considerably from famine, and your correspondent from fever, but these are incidental to the march in this country. The Doctor tramped it on foot like a man of iron. On arrival at Unyanyembe I found that the Englishman Shaw whom I had turned back as useless, had about a month after his return succumbed to the climate of the interior and had died, as well as two Wanguana of the expedition who had been left behind sick. Thus during less than twelve months William Lawrence Farquhar, of Leith, Scotland, and John William Shaw, of London, England, the two white men I had engaged to assist me, had died; also eight baggage carriers and eight soldiers of the expedition had died.
