On the 7th of February news was brought that Sheikh Snay had carried out his intention of attacking Manua Sera, whom he found ensconced in a house at Tura. Manua, however, made his escape, when Snay plundered the whole district, and shot and murdered every one he fell in with, carrying off a number of slaves. The chief, in consequence, threatened to attack Caze as soon as the merchants had gone off on their expeditions in search of ivory. Soon after this it was reported that Snay and other Arabs had been killed, as well as a number of slaves. This proved to be true. Finding that nothing more could be done at Caze, the travellers, assembling their caravan, commenced their march northward on the 17th of March. On the 24th they reached Mininga, where they were received by an ivory merchant named Sirboko. Here one of Sirboko's slaves, who had been chained up, addressed Speke, piteously exclaiming: "Oh, my lord, take pity on me! When I was a free man, I saw you on the Tanganyika lake; my people were there attacked by the Watuta, and, being badly wounded, I was left for dead, when, recovering, I was sold to the Arabs. If you will liberate me, I will never run away, but serve you faithfully." Touched by this appeal, Speke obtained the freedom of the poor man from his master, and he was christened Farham, or Joy, and enrolled among his other freemen. The abominable conduct of the Arabs, who persisted in attacking the natives and devastating the country, placed the travellers in an awkward position. The Hottentots, too, suffered so much from sickness that, as the only hope of saving their lives, it was necessary to send them back to Zanzibar. Speke therefore found it necessary to return to Caze, which he reached on the 2nd of May, leaving Grant, who was ill, behind at Mininga. He here heard of a tribe of cannibals, who, when they cannot get human flesh, give a goat to their neighbours for a dying child, considering such as the best flesh. They are, however, the only cannibals known in that district.
