Among the natives of Obbo, who had accompanied us to Latooka, was a man named Wani, who had formerly travelled far to the south, and had offered to conduct Ibrahim to a country rich in ivory that had never been visited by a trader: this man had accordingly been engaged as guide arid interpreter. In an examination of Wani I discovered that the cowrie-shells were brought from a place called "Magungo." This name I had previously heard mentioned by the natives, but I could obtain no clue to its position. It was most important that I should discover the exact route by which the cowries arrived from the south, as it would be my guide to that direction. The information that I received from Wani at Latooka was excessively vague, and upon most slender data I founded my conclusions so carefully that my subsequent discoveries have rendered most interesting the first scent of the position which I eventually followed with success. I accordingly extract, verbatim, from my journal the note written by me at Latooka on the 26th of May, 1863, when I first received the clue to the Albert N'yanza: "I have had a long examination of Wani, the guide and interpreter, respecting the country of Magungo. Loggo, the Bari interpreter, has always described Magungo as being on a large river, and I have concluded that it must be the Asua; but, upon cross-examination, I find he has used the word 'Bahr' (in Arabic signifying river or sea) instead of 'Birke' (lake). This important error being discovered gives a new feature to the geography of this part." According to his description, Magungo is situated on a lake so large that no one knows its limits. Its breadth is such that, if you journey two days east and the same distance west, there is no land visible on either quarter, while to the south its direction is utterly unknown. Large vessels arrive at Magungo from distant and unknown parts, bringing cowrie-shells and beads in exchange for ivory. Upon these vessels white men have been seen. All the cowrie-shells used in Latooka and the neighbouring countries are supplied by these vessels, but none have arrived for the last two years. "His description of distance places Magungo on about the 2 degrees N. lat. The lake can be no other than the 'N'yanza,' which, if the position of Magungo be correct, extends much farther north than Speke had supposed. The 'white men' must be Arab traders who bring cowries from Zanzibar. I shall take the first opportunity to push for Magungo. I imagine that country belongs to Kamrasi's brother, as Wani says the king has a brother who is king of a powerful country on the west bank of the Nile but that they are ever at war with each other.
