DISCOVERY OF THE DUERU. 507 WADELAI, October 26, 1886.

Dear FRiIEND,—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 themselves, 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.

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 lke 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 discovery 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 Duéru 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 Hameurko is situated on its banks, at a short distance from the lake, and a considerable * See page 162.
