Sultan Mahaya was considered the best and most just ruler in those quarters; and when Speke proposed crossing the lake to the island of the Ukerewe, he urged him on no account to make the attempt. Mansur also did his best to dissuade him, and, boats not being obtainable, he was compelled to give up his design.

Speke, arguing from the fact that the source of the Nile at the highest spot which had been reached, two thousand feet above the level of the sea, is considerably lower than the surface of the lake, which is four thousand feet, is of opinion that the waters of the lake must flow into it. The lake has, however, numerous feeders which flow from the Mountains of the Moon. Indeed, from that and several other reasons, he felt convinced that the lake is the real and long-looked-for source of the Nile.

As no boats of any size were to be obtained, and having gained all the information he could, regretting that he was unable to extend his explorations, he bade the Sultan and his Arab friend adieu, and on the 6th of August commenced his return journey.

The country through which he passed abounds in game. Elephants are finer here than in any other part of the world, and some have tusks exceeding five hundred pounds the pair in weight. The people are mostly agricultural; and when a stranger comes among them, they welcome him, considering his advent as a good omen, and allow him to do what he likes.

His black attendants were in much better humour on the return journey, as they were now going home, and, as the country was well stocked with cattle, they could obtain as much meat as was required. One village through which he passed, being full of sweet springs, had a dense population possessing numerous herds of cattle.

“If they were ruled by a few score of Europeans, what a revolution a few years would bring forth! An extensive market would be opened to the world, and industry and commerce would clear the way for civilisation and enlightenment,” Speke remarks.

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 Cazé, 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.
