The 24th of June, 1861, was a memorable day. Although this was actually the beginning of my work, I felt that by the experience of this night I had obtained a clew to one portion of the Nile mystery, and that, as “coming events cast their shadows before,” this sudden creation of a river was but the shadow of the great cause. The rains were pouring in Abyssinia! THESE WERE SOURCES OF THE NILE!
The journey along the margin of the Atbara was similar to the route from Berber, through a vast desert, with a narrow band of trees that marked the course of the river. The only change was the magical growth of the leaves, which burst hourly from the swollen buds of the mimosas. This could be accounted for by the sudden arrival of the river, as the water percolated rapidly through the sand and nourished the famishing roots.
