Many at home imagine that the death-knell of slavery was struck with the events which followed the death of Livingstone. In the great explorer's time we heard much of slavery; we were often appealed to; the Government busied itself; something was really done. But the wail is already forgotten, and England hears little now of the open sore of the world. But the tragedy I have alluded to is repeated every year and every month--witness such recent atrocities as those of the Upper Congo, the Kassai and Sankaru region described by Wissmann, of the Welle-Inakua district referred to by Van Gele. It was but yesterday that an explorer, crossing from Lake Nyassa to Lake Tanganyika, saw the whole southern end of Tanganyika peopled with large and prosperous villages. The next to follow him found not a solitary human being--nothing but burned homes and bleaching skeletons. It was but yesterday--the close of 1887--that the Arabs at the north end of Lake Nyassa, after destroying fourteen villages with many of their inhabitants, pursued the population of one village into a patch of tall dry grass, set it on fire, surrounded it, and slew with the bullet and the spear those who crawled out from the more merciful flames. The Wa-Nkonde tribe, to which these people belonged, were, until this event, one of the most prosperous tribes in East Central Africa. They occupied a country of exceptional fertility and beauty. Three rivers, which never failed in the severest drought, run through their territory, and their crops were the richest and most varied in the country. They possessed herds of cattle and goats; they fished in the lake with nets; they wrought iron into many-patterned spearheads with exceptional ingenuity and skill; and that even artistic taste had begun to develop among them was evident from the ornamental work upon their huts, which were themselves unique in Africa for clever construction and beauty of design. This people, in short, by their own inherent ability and the natural resources of their country, were on the high road to civilization. Now, mark the swift stages in their decline and fall. Years ago an almost unnoticed rill from that great Arab stream, which with noiseless current and ever-changing bed has never ceased to flow through Africa, trickled into the country. At first the Arab was there on sufferance; he paid his way. Land was bought from the Wa-Nkonde chiefs, and their sovereignty acknowledged. The Arab force grew. In time it developed into a powerful incursion, and the Arabs began openly to assert themselves. One of their own number was elevated to the rulership, with the title of "Sultan of Nkonde." The tension became great, and finally too severe to last. After innumerable petty fights the final catastrophe was hurried on, and after an atrocious carnage the remnant of the Wa-Nkonde were driven from their fatherland. Such is the very last chapter in the history of Arab rule in Africa.
