After a treacherous attack by the people of King Chumbiri——Stanley’s thirty-second battle——the natives showed a more peaceable disposition. They had heard of western coast white men and knew something of their ways. So there was a pleasant flow of water and a safe shore, for many days. But now the river was about to change. It received the Ikelemba, a powerful stream of tea-colored water, 1000 yards wide. Its waters flowed along in the same bed, unmixed with those of the Congo, for 150 miles. This immense tributary and that of the Ibari, were reported to come from great lakes, 800 miles to the south, and probably the same that Livingstone and Cameron both mention in their travels. For 900 miles the Congo has had a fall of only 364 feet, or a third of a foot to the mile. We are now within 400 miles of the Atlantic, yet 1150 feet above it, and on the edge of the great table lands of Central Africa. The days of smooth sailing are at an end. The mountains come close to the stream, and the channel narrows. The white chalky cliffs remind Frank Pocock of the coasts of Dover in his own England. A roar is heard in advance. The cataracts have begun again, and they sound as ominously as the war-cry of the natives hundreds of miles back in the woods and jungles. We have now been over four months on this river, and the next two hundred miles are to be the most tedious, laborious and disastrous of all. The terrors of Stanley Falls are here duplicated a thousand times. Bluffs rise 1500 feet high. Between them the river rushes over piles of boulders, or shoots with frightful velocity past the bases of impending crags, up which one must quickly scramble or else be carried into the boiling whirlpools below. These falls we shall call the “Livingstone Falls.” In their general features they are not like Niagara, or Victoria on the Zambesi, but a succession of headlong rushes, as if the river were tearing down a gigantic rock stairway. Of the Great Ntamo Fall, Stanley says: “Take a strip of sea, blown over by a hurricane, four miles in length by half a mile in breadth, and a pretty accurate conception of its rushing waves may be obtained. Some of the troughs were one hundred yards in length, and from one to another the mad river plunged. There was first a rush down into the middle of an immense trough, and then, by sheer force, the enormous volume would lift itself upwards steeply until, gathering itself into a ridge, it suddenly hurled itself twenty or thirty feet straight upwards before rolling down into another trough. The roar was deafening and tremendous. I can only compare it to the thunder of an express train through a rock tunnel.”
