DISCOVERY OF THE DU^RU. 507 



Wadelai, October 26, 1886. 



Dear Friend, — Before Dr. Junker left Uganda for the coast, 

 he collected a caravan, after immense difficulty, and with the 

 aid of Mr. Mackay of the Church Missionary Society, and 

 gained permission from King Mwanga to send it here. Besides 

 a good quantity of cloth, there were many presents from them- 

 selves, as well as newspapers from 1884 to 1886, a few books, 

 Graphics, and — what pleased me most and will prove most 

 valuable — a good many numbers of Nature ; so that at last 

 I am permitted once more to see what is taking place in 

 the scientific world. I see with deep sorrow that many of 

 my old friends have gone before me to their last rest — Marno, 

 Hansal, Dr. Behm, Dr. Nachtigal — all are no more. I am 

 now almost the last of those who knew the Sudan ; most 

 of my friends have gone to rest, having finished their fight — 



whilst I ? In one of your former letters you ask me to 



send one of my papers to be published in England, so I send 

 you the enclosed paper, which you can publish where you like.* 

 It is an account of a tour to the Albert Nyanza, which I 

 wrote on purpose for you. You must excuse its many faults, 

 but the circumstances under which it was composed will, I 

 hope, be sufficient explanation of its shortcomings. Since I 

 wrote it, I have made two other excursions to the lake, and 

 have gathered a considerable amount of fresh details. I might 

 perhaps send at once the detailed map which I have drawn 

 up, but as there are several points which I should like to 

 clear up more fully, I will wait a while, and only give you, in 

 the meantime, the chief result of my work, which is the dis- 

 covery of a new river flowing from the Usongora mountains. 

 It is of considerable size, and flows into the lake at the south. 

 The river, which is called Kakibi by the Wasongora, and 

 Dueru by the Wamboga, contains a large island near its 

 junction with the lake. On account of numerous cataracts, 

 however, it is very difficult to navigate ; but, on the other 

 hand, it pours into the lake throughout the whole year a large 

 volume of water. The town of Hamgurko is situated on its 

 banks, at a short distance from the lake, and a considerable
