Dweru was discovered by Stanley in 1875, and named by him Beatrice Gulf. Stanley now ascertained that the two lakes were connected. His expedition crossed the Kafuru, as the connecting stream is called, and entered the till then unvisited Hima kingdom of Ankole. Stanley’s guess at the shape of the Albert Edward was incorrect, and it needed subsequent expeditions to give us a truer idea of the form and area of this sheet of water, the eastern shore of which still remains unsurveyed. [Illustration: SHORES OF THE VICTORIA NYANZA, NEAR EMIN PASHA GULF.] Passing through Ankole, Stanley reached the southwestern extremity of the Victoria Nyanza, which he named Emin Pasha Gulf. On his journeys of circumnavigation in 1875, he had been deceived by a chain of islands into an incorrect limitation of the area of the Victoria Nyanza in this direction. He now realised that the lake extends much further to the southwest than was previously thought by Speke and himself, and is therefore not of the heart-shape assigned to it in the earliest maps; it is, in fact, much longer from north to south than it is broad from east to west. The rest of Stanley’s great journey took him out of the Nile watershed. But the discoveries which he made in the Albertine region of the Nile basin whetted the curiosity of Emin Pasha, who longed to return to these mysterious regions. He did so in 1890, as a German official. Accompanied by Dr. Franz Stuhlmann, a very able explorer, he directed his steps to these regions of fascinating interest, the Snow-mountains, and the Great Forest. In 1891 Dr. Stuhlmann made an ascent of the Ruwenzori range on its western aspect nearly to the snow-line. He revealed the existence of its remarkable Alpine vegetation of giant groundsels and lobelias. He also attempted to discriminate between the many different snow-peaks of this lofty range, though with only partial success, his failure in arriving at a complete result, like that of subsequent travellers, being due to the constant presence of clouds. Emin and Stuhlmann together added a good deal to our knowledge of the Semliki, and to the clearing up of geographical points connected with the line of watershed between the Nile and the Congo systems immediately west of Lake Albert. Emin Pasha resolved to return by way of the Congo, and was therefore left to do so by Stuhlmann, who returned to his duties in German East Africa. Re-entering the great Congo forest, and following a northern affluent of the Ituri-Aruwimi, Emin was captured by one of the slave-trading, Arabised Manyema who had recently invaded this region to secure ivory and slaves. As a German official, Emin (together with other Germans) had confiscated property belonging to these Manyema, had released slaves, and had severely punished slave-raiders. From motives of revenge, therefore, he was sentenced to death by his captor, and his throat was cut in his house one day in October, 1892. [Illustration: DR. FRANZ STUHLMANN.
