Beyond Lake Nu the White Nile breaks into an intricate series of curves and meanders, through which its current rushes with great rapidity, and with such strength that the steamer was compelled to throw off the towing-rope of the two Nile boats, and leave them to themselves. The sailors and servants accordingly landed, and set to work with sturdy arms to haul them against the stream. But in the worst fury of the current the rope broke, and the boats drifting downward, seemed doomed to destruction. Osman Aga, a resolute and courageous soldier, who was on the deck of the steamer at the time, seized another rope and sprang instantly into the river. With vigorous strokes he made for the shore. He had almost gained it, and had flung the rope to the crew of the nearest boat, when the strength of the current overpowered him, and he sank! After awhile his surviving comrades recovered the brave fellow's body, and gave it honourable burial in the native fashion at the foot of a patriarchal tree, on the trunk of which was cut a memorial inscription. Some days after this sad event, Miss Tinne ascended the river to Heiligenkreuz, an Austrian missionary station. There she remained until mid-September, making a short excursion into the interior; crossing rivers, penetrating into swampy forests, and visiting villages inhabited by a quite naked population, feeding upon bats, snakes, termites, and raw roots. As the voyagers drew near Gondokoro they observed that the scenery assumed a grander character. The river-banks lay deep in the shadow of luxuriant tropical forests, in the recesses of which the ruins of ancient buildings were sometimes visible. Gondokoro, long regarded as the _ne plus ultra_ of the Nile Valley, was reached on the 30th of September. It proved to be the farthest limit of the African explorations of our heroine. She ardently desired to advance; to share some of the glory which crowns the names of Speke and Grant, Baker and Petherick; to behold with her own eyes the vast expanse of the blue Victorian Sea; to trace to its fountain-head the course of the Nile; but the authorities threw obstacles in her way which proved to be insurmountable. Apart from these, the progress of the expedition was arrested by the malarious fever which attacked herself and most of her followers. In her own case the attack was so severe as at one time to threaten her life.
