ABSTRACT
Since Ludwig Krapf had left the East African coast in 1855, the Royal Geographical Society had sent Burton and Speke into the interior to settle the issue of the Nile watershed. Krapf and Rebmann gave form to some of the whispered realities of interior, such as Lake Zamburu. But more important, they both traveled beyond the coast and substantially added to what was known about East Africa's rivers and mountains. Avanchers was clearly familiar with the work of Krapf, Rebmann, and Erhardt and also with the writings of the armchair geographer James MacQueen. New and Wakefield were to work together for next decade, and unlike Krapf and Rebmann, they had an extremely harmonious relationship. According to Thomas Wakefield, Sadi had some interesting things to say about the lake: It's the limit of Sadi's journey from Sigirari. Sadi's description of the lake was of great significance because it included measurements that later proved to be accurate to within a few miles.
