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. Had I been alone, it would have been no hard lot to die upon the untrodden path before me; but there was one who, although my greatest comfort, was also my greatest care, one whose life yet dawned at so early an age that womanhood was still a future. I shuddered at the prospect for her, should she be left alone in savage lands at my death; and gladly would I have left her in the luxuries of home instead of exposing her to the miseries of Africa. It was in vain that I implored her to remain, and that I painted the difficulties and perils still blacker than I supposed they really would be. She was resolved, with woman's constancy and devotion, to share all dangers and to follow me through each rough footstep of the wild life before me. "And Ruth said, Entreat me not to leave thee, or to return from following after thee; for whither thou goest I will go, and where thou lodgest I will lodge; thy people shall be my people, and thy God my God; where thou diest will I die, and there will I be buried: the Lord do so to me, and more also, if aught but death part thee and me." Thus accompanied by my wife, on the 15th of April, 1861, I sailed up the Nile from Cairo. The wind blew fair and strong from the north, and we flew toward the south against the stream, watching those mysterious waters with a firm resolve to track them to their distant fountain. I had a firman from the Viceroy, a cook, and a dragoman. Thus my impedimenta were not numerous. The firman was an order to all Egyptian officials for assistance; the cook was dirty and incapable; and the interpreter was nearly ignorant of English, although a professed polyglot. With this small beginning, Africa was before me, and thus I commenced the search for the sources of the Nile. On arrival at Korosko, twenty-six days from Cairo, we started across the Nubian Desert. During the cool months, from November until February, the desert journey is not disagreeable; but the vast area of glowing sand exposed to the scorching sun of summer, in addition to the withering breath of the simoom, renders the forced march of two hundred and thirty miles in seven days, at two and a half miles per hour, one of the most fatiguing journeys that can be endured.
