To dare the cataract was certain death. The canoes were brought to anchor, and a battle with the natives began. They were too strong, and Stanley retraced his course a little way, where he landed and encamped. Another trial, a fierce surge through the ranks armed with lances and poisoned arrows, gave them headway. The first cataract was rounded, and now they were in the midst of that wonderful series of waterfalls, where the Lualaba cuts its way for seventy miles through a range of high hills, with seven distinct cataracts, in a channel contracted to a third of its ordinary breadth, where the stream tumbles and boils, flinging itself over ledges of rock, or dashing frantically against the walls that hem it in, as if it were struggling with all its giant power to escape from its prison. Within the gorge the ear is stunned with the continual din of the rushing waters, and the attention kept constantly on the strain to avoid the perils of rock, rapid, whirlpool, and cataract with which the course is strewn. With extreme caution and good-luck the rapids may be run in safety; but how are frail canoes to survive the experiment of a plunge over a perpendicular ledge, in company with millions of tons of falling water, into an abyss of seething and gyrating foam? Ashore, the cannibal natives lie in wait to oppose a landing, or better still, to slay or capture victims for their sport or larder. A toilsome ascent has to be made to the summit of the bluffs forming the river banks over rough boulders and through tangled forest. In places where the fall of the stream is slight it may be possible to lower down the boats, by means of strong hawsers of creepers, to the pool below; but in other cases the canoes have to be dragged painfully up the cliffs, and launched again with almost equal toil where the current seems a little calmer. All this while the poisoned arrows are hissing through the air, spears are launched out of every thicket, and stones are slung or thrown at the unlucky pioneers from each spot of vantage. Only by van and rear guards and flanking parties, and maintaining a brisk fire can the assailants be kept at bay. The vindictive foe are as incessant in their attacks by night as by day; and the whiz of the flying arrow, the hurtling of lances through the temporary stockade and the sharp crack of the rifle, mingle with the dreams of the sleeper. The descent of Stanley Falls was not made without loss of life and property. In spite of every precaution, canoes would be dragged from their moorings and be sucked down by the whirlpools or swept over the falls; or the occupants would lose nerve in the presence of danger, and allow their craft to drift into the powerful centre current, whence escape was hopeless.
