Expanding Dr Schweinfurth's remarks, he explained that "it was contended that the Nile did not flow out of Lake Victoria, and thence through Lake Albert, and so northward, but that one river flowed out of Lake Victoria and another out of Lake Albert, and that these two rivers united and formed the Nile. This statement could not be positively denied, inasmuch as no one had actually gone along the river from Foweira to Magungo. So I went along it with much suffering, and settled the question. I also found that from Foweira or Karuma Falls there was a series of rapids to Murchison Falls, thus _by degrees_ getting rid of the 1000-feet difference of level between Foweira and Magungo." While mapping this region, Gordon one day marched eighteen miles through jungle and in pouring rain, and on each of the four following days he also walked fifteen miles--and the month was August, only a few miles north of the Equator, or, in other words, the very hottest period of the year. Having established the course of the Nile and its navigability to the Murchison Falls close to the Victoria Nyanza, General Gordon gave what he thought was a finishing touch to this exploring expedition by effecting an arrangement with King Mtesa. But in order to explain the exact significance of this step, and the consequent disappointment when it was found that the arrangement was illusory and destitute of practical value, it is necessary to go back a little, and trace the course of events in the Uganda region.
