In his trip to Loanda, Livingstone had been seeking an outlet to the Atlantic for the Makalolo people. On his return, they were dissatisfied with his route and preferred an outlet eastward toward the Indian Ocean. He therefore resolved to explore a path in this direction for them. With all his wants abundantly supplied by the friendly chief Sekelutu, he set out for this great journey and after a fortnight’s laborious travel reached the Zambesi at the mouth of the Chobe, in November 1855. Sailing down the Zambesi, Livingstone saw rising high into the air before him, at a distance of six miles, five pillars of vapor with dark smoky summits. The river was smooth and tranquil, and his boat glided placidly over water clear as crystal, past lovely islands, densely covered with tropical vegetation, and by high banks with red cliffs peering through their back-ground of palm trees. The traveller was not altogether unprepared for the marvels that lay ahead. Two hundred miles away he had heard of the fame of the great gorge Mozi-oa-Tunia——“the sounding smoke,” where the Zambesi mysteriously disappeared. As the falls were approached the pulse of the river seemed to quicken. It was still more than a mile wide, but it hurried over rapids, and chafed around points of rocks, and the most careful and skillful navigation was needed, lest the canoe should be dashed against a reef, or hurried helplessly down the chasm. The mystery in front became more inexplicable the nearer it was approached, for the great river seemed to disappear suddenly under ground, leaving its bed of hard black rock and well defined banks. By keeping the middle of the stream and cautiously paddling between the rocks, he reached a small island on the tip of the Victoria Falls——a spot where he planted some fruit trees, and for the only time on his travels carved his initials on a tree in remembrance of his visit.
