The country is also, he says, high, dry, and healthy, while the air is neither too hot nor too cold. On the evening of the 25th of August he marched into Caze, under the influence of a cool night and bright moon, his attendants firing off muskets and singing, while men, women, and children came flocking out, piercing the air with loud, shrill noises. The Arabs all came forth to meet him and escort him to their depot, where Captain Burton, who had been very anxious as to his safety, greeted him, numerous reports having been set afloat about him. Captain Burton being now restored to health, they set off together for Zanzibar, whence they shortly afterwards returned to England. CHAPTER FOURTEEN.

Captain Speke, who had already made two expeditions into Africa, which have been described--on the second of which he discovered the great lake, Victoria Nyanza--started, on the 20th of July, 1858, on a third expedition, in the hopes of proving that the Nile has its source in that lake. He was accompanied by an old Indian brother officer, Captain Grant. Having reached the island of Zanzibar, where some time was spent in collecting a sufficient band of followers, they left Zanzibar on the 25th of September, in a corvette placed at their disposal by the sultan, and crossed over to Bagomoyo, on the mainland.
