Next morning (January 27) I had instructions to set up a stone-heap on a little hill about four miles from camp. I made my way to it direct through a tangle of jungle-growths, and from the summit obtained the photograph of the source of the river at the point of outflow from the lake which forms the frontispiece of this book. I believe this to be the only photo of the place in existence. I descended the hill, and walked along the riverbank towards the place where we had arranged to lunch. The soil was boggy, covered in some parts by reed-grass and in others by jungle-growths. Hippo spoor was everywhere. This tract is not well-wooded; there are a few palms, and some scattered trees of other kinds, chiefly mimosas. The bed of the river is hard rock, and the water was clear and drinkable. The depth varied very greatly, from a few inches in the rapids to some six metres in the pools. I saw the stream at its lowest. Watermarks showed clearly that in flood time it rises sixteen to eighteen feet above this level. When I reached the place where we were to lunch, I saw a big herd of hippos basking on the surface of the river. Crawley and I walked towards them, and when they saw us, they sank, leaving only their snouts visible. These offered an interesting target for rifle-fire, and for awhile the hippos watched our practice with unconcern. Then a shot told—there was a “general post”—and not a sign of the huge beasts remained in sight. After this I took my rod and tried for a fish in a pool below a rapid. While I was standing there, I saw a large white eagle, a splendid fellow, which had been watching me fishing, swoop from the branch of a high tree. He circled twice above me, and then pounced upon a young duck, that was hiding under a ledge in the river-bed, and bore it off. The parent birds were close at hand, and I heard their loud, frightened, and indignant cackling. I do not think wild duck are plentiful hereabouts. No doubt they are harried by these eagles and have to find safer breeding-places. We saw only a very few. I landed a plump fish of the perch tribe, which weighed about four pounds. He showed no fight, but came tamely into shallow water, where the boy who was with me picked him up. My friends came late into camp after a hard day’s work upon their survey. The high ground beside the head waters of the Blue Nile is pleasant and healthy and could support a large population. The maximum temperature in the day, when we were there, was about eighty-five degrees. Usually a cool, exhilarating breeze was blowing, and we did not feel the heat disagreeably. If this place were more easily accessible, it would be a perfect pleasure-resort and a most valuable sanatorium for residents in the Soudan.
