Other Arab and Wasuahili merchants have corroborated Snay's statement, as also a Hindi merchant, called Musa, whom I especially mention, as I consider him a very valuable informant--not only from the straightforward way he had of telling his story, but also because we could converse with one another direct, and so obviate any chance of errors. After describing his route to the north in minute detail, stage by stage, with great precision, which was to the same effect as all the other accounts, he told me of a third large river to the northward of the Line, beyond Uganda; this he spoke of as much larger than the Katonga, and generally called the Usoga River, because it waters that district. Although he had recently visited Kibuga, and had lived with Sultan Mtésa, the present reigning monarch in place of Sunna, who died since Snay was there, he had no positive or definite idea of the physical features of any of the country beyond the point which he had reached; but he produced a negro slave who had been to Usoga, and had seen the river in question. This man called the river Kivira, and described it as being much broader, deeper, and stronger in its current than either the Katonga or Kitangulé river; that it came from the lake, and that it intersected stony hilly ground on its passage to the north-west. This river Kivira, I now believe (although I must confess I did not until I made Snay alter his original statement about the direction of its flow, and so proved he meant this for his Jub), is the Nile itself. On a subsequent occasion, when talking to a very respectable Suahili merchant, by name Sheikh Abdullah bin Nasib, about the N'yanza, he corroborated the story about the mariners, who are said to keep logs and use sextants, and mentioned that he had heard of the Kidi and Bari people living on the Kivira river. Now, the Bari people mentioned by him are evidently those who have long since been known to us as a tribe living on the Nile in latitude 5° north and longitude 32° east, and described by the different Egyptian expeditions sent up the Nile to discover its source. M. Ferdinand Werne (says Dr Beke) has published an account of the second expedition's proceedings, in which he took part; and which, it appears, succeeded in getting farther up the river than either of the others. "The author states that, according to Lacono, King of Bari, the course of the river continues thence southwards a distance of thirty days' journey." This, by Dr Beke's computation, places the source of the Nile just where I have since discovered the N'yanza's southern extremity to be--in the second degree south latitude, lying in the Unyamuézi country.[48]
