The easternmost island in mid-river is about 100 yards across at its widest part, and between it and another island is a distance of from 250 to 300 yards. From the second island to the low shore opposite Nyangwé is about 250 yards, and these channels have a slightly swifter flow than the main river. The mean depth of the central channel was 12½ feet, the westernmost 11 feet, and the entire width of clear water flow was about 1300 yards. During the months of April, May, and June, and the early part of July, the Lualaba is full, and overspreads the low lands westward for nearly a mile and a half. The Lualaba then may be said to be from four thousand to five thousand yards wide opposite Nyangwé. The Arabs, wherever they settle throughout Africa, endeavour to introduce the seeds of the vegetables and fruit-trees which grow in their beloved island of Zanzibar. At Unyanyembé, therefore, they have planted papaws, sweet limes, mangoes, lemons, custard-apples, pomegranates, and have sown wheat and rice in abundance. At Ujiji also they have papaws, sweet limes, pomegranates, lemons, wheat, rice, and onions. At Nyangwé, their fruit consists of pine-apples, papaws, and pomegranates. They have succeeded admirably in their rice, both at Nyangwé, Kasongo’s, and Mwana Mamba’s. Onions are a failure, the Arabs say, because of a species of worm which destroys them. The banana (_Musa paradisaica_) and plantain (_Musa sapientum_) are indigenous. The Wagenya, as the Arabs call them, or Wenya—pronounced Wainya—as they style themselves, are a remarkable tribe of fishers, who inhabit both banks of the Lualaba, from the confluence of the Kamalondo on the left bank down to the sixth cataract of the Stanley Falls, and on the right bank from the confluence of the Luama down to Ubwiré or Usongora Meno. The Wenya were the aborigines of Nyangwé, when the advanced party of Muini Dugumbi appeared on the scene, precursors of ruin, terror, and depopulation to the inhabitants of 700 square miles of Manyema. Considering that the fertile open tract of country between the Luama and Nyangwé was exceedingly populous, as the ruins of scores of villages testify, sixty inhabitants to the square mile would not be too great a proportion. The river border, then, of Manyema, from the Luama to Nyangwé, may be said to have had a population of 42,000 souls, of which there remain probably only 20,000. The others have been deported, or massacred, or have fled to the islands or emigrated down the river. The Arabs and Wangwana have murdered also the word Lualaba, or Lualowa. They have given us instead Ugalowa, Ugarowa, which must be rejected, as I never heard a single native west of the Tanganika use the term. It originated, no doubt, from some slave of Uhiyau, or Nyassa, Bisa, Unyamwezi, or other parts. Had an intelligent Arab heard the name first, we should most probably have received something nearer the correct word.
