The history of events at Zanzibar for some years following consists principally of relations of capture of slave-dhows and the confiscation of the vessels, the visit of the Zanzibar prince to England, the appointment of a number of vice-consuls to the principal ports along the coast, the departures of explorers for inner Africa, the gradual but steady increase of missionaries in the interior, and the establishment of Christian missions at Usambara, Mombasa, and Nyassa. Meanwhile the Arabs in the far interior had discovered a new field for bolder operations in a country west of Lake Tanganika, called Manyuema, and the enormous forested area adjoining it to the north, which has lately been discovered to be about 400,000 square miles in extent. Nyangwé, the principal town of Manyuema, is situate but a few miles south of the vast forest, on the right bank of the Lualaba. It was the furthest point of Livingstone’s explorations. Manyuema is surpassingly beautiful, the soil is exceedingly fertile, and the people, though troubled by tribal feuds, are industrious cultivators. By the time Livingstone had penetrated the country the Arabs had assumed lordship over it, and each chief was compelled to pay tribute to them in ivory. The Arabs not only monopolized the ivory, but the fear of them was so great among the Manyuema that, to protect themselves from too many masters, they elected to serve some one powerful Arab, to whom they surrendered themselves, their liberties, as well as their properties of all kinds. In a few years Manyuema was emptied of its elephant teeth. The Arabs then began to extend their operations into the forest, suffering many a disaster and mishap as they advanced. But continuous practice enabled them in the end to thwart the craft of the forest natives, and to acquire that experience by which eventually they easily became masters of every country they entered. The success attending the ventures of such men as Dugumbi, Mtagamoyo, Mohammed-bin-Nasur, and Abed-bin-Salim, and scores of lesser leaders, increased the avarice and excited the ardor of younger and more daring spirits. An apprenticeship with men who had grown gray in the arts of slave-catching and ivory-raiding had taught them that it was a waste of time to pretend to barter cloth and beads as practised in lands east of Lake Tanganika. They had realized how complete was the isolation of the forest aborigines, how the little settlements buried in the recesses of the forest were too weak to resist their trained battalions, and how the natives shrank from facing the muzzles of their thundering guns, and how they might range at will and pillage to their hearts’ content through an unlimited area without let or hindrance.
