I could not conceive that anything in this world has power to resist a determined will, so long as health and life remain. The failure of every former attempt to reach the Nile source did not astonish me, as the expeditions had consisted of parties, which, when difficulties occur, generally end in difference of opinion and in retreat; I therefore determined to proceed alone, trusting in the guidance of a Divine Providence and the good fortune that sometimes attends a tenacity of purpose. I weighed carefully the chances of the undertaking. Before me, untrodden Africa; against me, the obstacles that had defeated the world since its creation; on my side, a somewhat tough constitution, perfect independence, a long experience in savage life, and both time and means, which I intended to devote to the object without limit.
England had never sent an expedition to the Nile sources previous to that under the command of Speke and Grant. Bruce, ninety years before, had succeeded in tracing the source of the Blue or Lesser Nile; thus the honor of that discovery belonged to Great Britain. Speke was on his road from the South, and I felt confident that my gallant friend would leave his bones upon the path rather than submit to failure. I trusted that England would not be beaten, and although I hardly dared to hope that I could succeed where others greater than I had failed, I determined to sacrifice all in the attempt.
