The party ascended the great river by the Kongone mouth; they were on board a small steamer named the "Ma-Robert," and reached Teté on the 8th of September.
During the following year they investigated the lower course of the Zambesi, and its left affluent the Shiré, and having visited Lake Shirwa, they explored the territory of the Manganjas, and discovered Lake Nyassa. In August, 1860, they returned to the Victoria Falls.
Early in the following year, Bishop Mackenzie and his missionary staff arrived at the mouth of the Zambesi.
In March an exploration of the Rovouma was made on board the "Pioneer," the exploring party returning afterwards to Lake Nyassa, where they remained a considerable time. The 30th of January, 1862, was signalized by the arrival of Mrs. Livingstone, and by the addition of another steamer, the "Lady Nyassa;" but the happiness of reunion was very transient; it was but a short time before the enthusiastic Bishop Mackenzie succumbed to the unhealthiness of the climate, and on the 27th of April Mrs. Livingstone expired in her husband's arms.
A second investigation of the Rovouma soon followed and at the end of November the doctor returned to the Zambesi, and reascended the Shire. In the spring of 1803 he lost his companion Mr. Thornton, and as his brother and Dr. Kirk were both much debilitated, he insisted upon their return to Europe, while he himself returned for the third time to Lake Nyassa, and completed the hydrographical survey which already he had begun.
A few months later found him once more at the mouth of the Zambesi; thence he crossed over to Zanzibar, and after five years' absence arrived in London, where he published his work, "The exploration of the Zambesi and its affluents."
Still unwearied and insatiable in his longings, he was back again in Zanzibar at the commencement of 1866, ready to begin his fourth journey, this time attended only by a few sepoys and negroes. Witnessing on his way some horrible scenes which were perpetrated as the result of the prosecution of the slave-trade, he proceeded to Mokalaosé on the shores of Lake Nyassa, where nearly all his attendants deserted him, and returned to Zanzibar with the report that he was dead.
Dr. Livingstone meanwhile was not only alive, but undaunted in his determination to visit the country between the two lakes Nyassa and Tanganyika. With none to guide him except a few natives, he crossed the Loangona, and in the following April discovered Lake Liemmba. Here he lay for a whole month hovering between life and death, but rallying a little he pushed on to the north shore of Lake Moero. Taking up his quarters at Cazembé for six weeks, he made two separate explorations of the lake, and then started farther northwards, intending to reach Ujiji, an important town upon Lake Tanganyika; overtaken, however, by floods, and again abandoned by his servants, he was obliged to retrace his steps. Six weeks afterwards he had made his way southwards to the great lake Bangweolo, whence once more he started towards Tanganyika.
This last effort was most trying, and the doctor had grown so weak that he was obliged to be carried, but he reached Ujiji, where he was gratified by finding some
