And again:——“The story of the descent of the great river is an Iliad in itself. Through hunger and weariness; through fever, dysentery, poisoned arrows, and small-pox; through bellowing hippopotami, crocodiles, and monsters; past mighty tributaries, themselves great first-class rivers; down roaring rapids, whirlpools, and cataracts; through great canoe-fleets of saw-teethed, fighting, gnashing cannibals fiercer than tigers; through thirty-two battles on land and river, often against hundreds of great canoes, some of them ninety feet long and with a hundred spears on board; and, at last, through the last fearful journey by land and water down the tremendous cañon below Stanley Pool, still they went on, and on, relentlessly on, till finally they got within hailing and helping distance of Boma, on the vast estuary by the sea; and on August 9, 1877, the news thrilled the civilized world that Stanley was saved, and had connected Livingstone’s Lualaba with Tuckey’s Congo! After 7,000 miles’ wanderings in 1,000 days save one from Zanzibar, and four times crossing the Equator, he looked white men in the face once more, and was startled that they were so pale! Black had become the normal color of the human face. Thus the central stream of the second vastest river on the globe, next to the Amazon in magnitude, was at last explored, and a new and unsuspected realm was disclosed in the interior of a prehistoric continent, itself the oldest cradle of civilization. The delusions of ages were swept away at one masterful stroke, and a new world was discovered by a new Columbus in a canoe.” [Illustration: THE BELLOWING HIPPOPOTAMI.] It was on that memorable march that he came across the wily Arab, Tippoo Tib, at the flourishing market-town of Nyangwe, who was of so much service to Stanley on his descent of the Lualaba (Congo) from Nyangwe to Stanley Falls, 1,000 miles from Stanley Pool, but who has since figured in rather an unenviable light in connection with efforts to introduce rays of civilization into the fastnesses of the Upper Congo. This, as well as previous journeys of Stanley, established the fact that the old method of approaching the heart of the Continent by desert coursers, or of threading its hostile mazes without armed help, was neither expeditious nor prudent. It revolutionized exploration, by compelling respect from hostile man and guaranteeing immunity from attack by wild beast. For nearly three years Stanley was lost to the civilized world in this trans-continental journey. Its details, too, are narrated elsewhere in this volume, with all its vicissitude of 7,000 miles of zigzag wandering and his final arrival on the Atlantic coast——the wonder of all explorers, the admired of the scientific world.
