We have no time to accompany Livingstone on his six years' journeys in East Africa. Among the most important discoveries he made was that of the great Lake Nyassa, from the neighbourhood of which 19,000 slaves were carried annually to Zanzibar, to say nothing of the far greater numbers who died on the way to the coast. One day Livingstone went down to the mouth of the Zambesi to meet an English ship. On board were his wife and a small specially built steamer called the Lady Nyassa, designed for voyages on rivers and lakes. Shortly afterwards his wife fell ill and died, and was buried under the leafy branches of a bread-fruit tree. In spite of his grief he went on with his work as diligently as before, and when the time came for him to sail home, he thought of selling the Lady Nyassa to the Portuguese. But when he heard that the boat was to be used to transport slaves, he kept it, steered a course for Zanzibar, and then resolved to cross the Indian Ocean in the small open boat by the use of both sails and steam. This was one of Livingstone's most daring exploits, for the distance to Bombay was 2500 miles across the open sea, and in the beginning of January the south-west monsoon might be expected with its rough, stormy seas. He hoped, however, to reach Bombay before the monsoon broke, so with three white sailors and nine Africans, and only fourteen tons of coal, he steamed out of the harbour of Zanzibar, saw the coast of Africa fade away and the dreary waste of water close round him on all sides.
Two of the white sailors fell ill and were unfit for work, and the bold missionary had to depend almost entirely on himself. Ocean currents hindered the progress of the Lady Nyassa, and for twenty-five days she was becalmed, for the coal had to be used sparingly, and when the sails hung limp from the mast there was nothing to be done but to exercise patience. Fortunately there was sufficient food and drinking water, and Livingstone was accustomed to opposition and useless waiting. He had to ride out two violent storms, and the Lady Nyassa was within a hair's breadth of turning broadside to the high seas. In view of the immense watery waste that still lay before him he meditated making for the Arabian coast, but as a favourable wind got up and the sailing was good he kept on his course. At length the coast of India rose up out of the sea, and after a voyage of six weeks the Lady Nyassa glided into the grand harbour of Bombay. The air was hazy and no one noticed the small boat, but when it was known that Livingstone was in the city, every one made haste to pay him homage.
In the year 1866 Livingstone was again in Africa. We find him at the mouth of the Rovuma, a river which enters the sea to the east of Lake Nyassa. He had thirty-seven servants, many of them from India, and one of his men, Musa, had been with him before. He crossed the country to Lake Nyassa, but when he wished to pass over to the eastern shore in native boats, he was stopped by the Arabs, who knew that he was the most formidable opponent of the slave-trade. He had no choice but to go round the lake on foot, and little by little he made contributions to human knowledge, drew maps, and made notes and collections. He came to districts he already knew, where black women were carried off by crocodiles on the bank of the Shiré River, where he had lost his wife, and where all the missionaries sent out on his recommendation had died of fever.
His staff of servants soon proved to be a worthless lot. The Indians were dismissed, and few of the others could be depended on. The best were Susi and Chuma, who by their faithfulness gained a great reputation both in Africa and Europe. Musa, on the contrary, was a scoundrel. He heard from an Arab slave-dealer that all the country through which Livingstone was about to travel was inhabited by a war-like tribe, who had lately fallen upon a party of forty-four Arabs and killed all but the narrator himself. Musa and most of his comrades were so frightened that they ran away. On his arrival at Zanzibar, Musa informed the British Consul that Livingstone had been attacked and murdered and all his goods plundered. The false account was so cleverly concocted and so thoroughly rehearsed that Musa could not be convicted of deceit. Every one believed him, and the English newspapers contained whole columns of reminiscences of the deceased. Only one friend of Livingstone, who had accompanied him on one of his journeys and knew Musa, had any doubts. He went himself to Africa, followed Livingstone's trail, and learned from the natives that the missionary had never been attacked as reported, but that he was on his way to Lake Tanganyika.
The road thither was long and troublesome, and the great explorer suffered severe losses. Provisions ran short, and a hired porter ran away with the medicine chest. From this time Livingstone had no drugs to allay fever, and his health broke down. But he came to the southern extremity of Tanganyika, and the following year discovered Lake Bangweolo. He rowed out to the islands in the lake, and very much astonished the natives, who had never seen a white man before. Extensive swamps lay round the lake, and Livingstone believed that the southernmost sources of the Nile must be looked for in this region. This problem of the watershed of the Nile so fascinated him that he tarried year after year in Africa; but he never succeeded in solving it, and never knew that the river running out of Bangweolo is a tributary of the Lualaba or Upper Congo.
Most of his men mutinied on the shore of Bangweolo. They complained of the hardships they endured and were tired of munching ears of maize, and demanded that their master should lead them to country where they could get sufficient food. Mild and gentle as always, Livingstone spoke to them kindly. He admitted that they were right, and confessed that he was himself tired of struggling on in want and hardship. They were so astonished at his gentleness that they begged to remain with him.
Livingstone was dangerously ill on this journey and had to be carried on a litter. There he lay unconscious and delirious with fever, and lost entirely his count of time. The troop moved again towards Tanganyika, and was to cross the lake in canoes to the Ujiji country on the eastern shore. If he could only get so far, he could rest there, and receive new supplies and letters from home.
Worn out and exhausted he at length reached Ujiji, a rendezvous for the Arab slave-dealers. But his fresh supplies had disappeared entirely. He wrote for more from the coast, and urged the Sultan of Zanzibar to see that nothing went astray. He wrote heaps of letters which never reached their destination. A packet of forty-two were sent off at one time, not one of which arrived, for at that time the tribes to the east of the lake were at war with one another.
Livingstone did not allow his courage to fail. No difficulties were great enough to crush this man. With Susi and Chuma and a party of newly enlisted porters, he set out westwards across the lake, his aim being to visit the Manyuema country, through the outskirts of which flows the Lualaba. If Livingstone could prove in which direction this mighty river ran, whether to the Mediterranean or the Atlantic, he could then return home with a good conscience. He had determined in his own mind that he would not leave the Dark Continent until he had solved the problem, and for this he sacrificed his life without result. The canoes sped over the lake, and on the western shore he continued his journey on foot to the land of the Manyuemas. He marched on westwards. When the rainy season came on he lost several months, and when he set out again on his next march he had only three companions, two of them being the faithful Susi and Chuma. In the dark thickets of the tropical forests he wounded his feet, dragged himself over fallen trunks and decaying rubbish, and waded across swollen rivers; and among the crowns of the lofty trees and in the dense undergrowth lurked malaria, an invisible miasma. He fell ill again and had to rest a long time in his miserable hut, where he lay on his bed of grass reading his tattered Bible, or listening to the native's tales of combats with men and apes, for gorillas lived in the forests.
Thus year after year passed by, and not the faintest whisper from the noisy world reached his ears. The only thing that retained him was the Lualaba. Did its waters run in an inexhaustible stream to the western ocean, or did they flow gently through forests, swamps, and deserts to Egypt? If he could only answer that question, he would go by the nearest way to Zanzibar and thence home. He had heard nothing of his children and friends for years. The soil of Africa held him prisoner in a network of forests and lianas.
