“‘I did try before setting out for Manyema,’ he said, ‘to engage canoes and proceed northward, but I soon saw that the people were all confederating to fleece me as they had Burton, and had I gone under such circumstances I should not have been able to proceed to Manyema to explore the central line of drainage, and of course the most important line--far more important than the line of the Tanganyika; for whatever connection there may be between the Tanganyika and the Albert the true sources of the Nile are those emptying into the central line of drainage. In my own mind I have not the least doubt that the Rusizi River flows from this lake into the Albert. For three months steadily I observed a current setting northward. I verified it by means of water plants. When Speke gives the altitude of the Tanganyika at only 1,880 feet above the sea I imagine he must have fallen into the error by frequently writing the Anno Domini, and thus made a slip of the pen; for the altitude is over two thousand eight hundred feet by boiling point, though I make it a little over three thousand feet by barometers. Thus you see that there are no very great natural difficulties on the score of altitude, and nothing to prevent the reasonable supposition that there may be a water connection by means of the Rusizi or some other river between the two lakes. Besides, the Arabs here are divided in their statements. Some swear that the river goes out of the Tanganyika, others that it flows into the Tanganyika.’ “Dr. Livingstone left the island of Zanzibar in March, 1866. On the 7th of the following month he departed from Mikindini Bay for the interior, with an expedition consisting of twelve Sepoys from Bombay, nine men from Johanna, of the Comoro Isles seven liberated slaves and two Zambesi men (taking them as an experiment), six camels, three buffaloes, two mules and three donkeys. He thus had thirty men, twelve of whom--viz., the Sepoys--were to act as guards for the expedition. They were mostly armed with the Enfield rifles presented to the Doctor by the Bombay Government. The baggage of the expedition consisted of ten bales of cloth and two bags of beads, which were to serve as currency by which they would be enabled to purchase the necessaries of life in the countries the Doctor intended to visit. Besides the cumbrous moneys they carried several boxes of instruments, such as chronometers, air thermometers, sextant and artificial horizon, boxes containing clothes, medicines, and personal necessaries.
