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.
