In this vast current, rushing along at the rate of thirty miles an hour, the strongest steamer would be as helpless as a cockle-shell, and as for frail canoes, they had to be dragged from rock to rock, or taken clear from the water and borne by land around the obstructions. Frequently canoes were wrecked and then a halt had to be ordered till new ones were hewn from trees. Yet amid trial, sickness and sore distress they had to pause at times in wonder before the imposing sights that opened on them. One was that of the Edwin Arnold River which flings itself with a single bound of 300 feet into the Congo, clearing the base of its cliff by ten yards. Still more wonderful is the cascade of the Nkenke, which is a plunge of a 1000 feet; and near by another with a fall of 400 feet. Many gaps were made in the ranks of Stanley’s companions through this “Valley of Shadow.” In one day (March 28) he saw eleven of his men swept over a cataract and disappear in the boiling waters below. First a boat, in which was Kalulu, an attendant of Stanley in all his journeys, was sucked within the power of a fall and plunged into the abyss. Hardly had the eye turned from this horror when another canoe was seen shooting down the stream toward what appeared to be certain death. By almost a miracle it made an easy part of the cataract and the occupants succeeded in reaching the shore in safety. Close behind came a third with a single occupant. As the boat made its plunge the occupant rose and shouted a farewell to his companions on the shore. Then boat and man disappeared. A few days afterwards he re-appeared like an apparition in camp. He had been tossed ashore far below and held a prisoner by the natives, who had picked him up more dead than alive. [Illustration: THE LADY ALICE IN THE CONGO RAPIDS.] On April 12, the “Lady Alice” herself, with her crew, came to the very verge of destruction. The boat was approaching a bay in which the camp for the night was to be made, when a noise like distant thunder fell on the ears of the crew. The river rose before them into a hill of water. It was a whirlpool, at its full. All hands bent to their paddles and the boat was plunged into the hill of water before it broke. They thus escaped being sucked into a vortex which would have sunk the boat and drowned all. As it was, the boat was whirled round and round through a succession of rapids, before the crew could bring her under control again. Fortunately the natives were still friendly and of superior type. They had many European manufactures, which pass from tribe to tribe in regular traffic, and enjoyed a higher civilization than those of the Central African regions. Stanley rested with these people for several days while his carpenter made two new canoes.
