We fully expected that the owners of the captives we had liberated would show their displeasure, at least by their tongues; but they seemed ashamed; only one ventured a remark, and he, in the course of common conversation, said, with a smile, "You took the Governor's slaves, didn't you?" "Yes, we did free several gangs that we met in the Manganja country." The Portuguese of Tette, from the Governor downwards, were extensively engaged in slaving. The trade is partly internal and partly external: they send some of the captives, and those bought, into the interior, up the Zambesi: some of these we actually met on their way up the river. The young women were sold there for ivory: an ordinary-looking one brought two arrobas, sixty-four pounds weight, and an extra beauty brought twice that amount. The men and boys were kept as carriers, to take the ivory down from the interior to Tette, or were retained on farms on the Zambesi, ready for export if a slaver should call: of this last mode of slaving we were witnesses also. The slaves were sent down the river chained, and in large canoes. This went on openly at Tette, and more especially so while the French "Free Emigration" system was in full operation. This double mode of disposing of the captives pays better than the single system of sending them down to the coast for exportation. One merchant at Tette, with whom we were well acquainted, sent into the interior three hundred Manganja women to be sold for ivory, and another sent a hundred and fifty. CHAPTER XI. Arrival of H.M.S. "Gorgon"--Dr. Livingstone's new steamer and Mrs. Livingstone--Death of Mrs. Livingstone--Voyage to Johanna and the Rovuma--An attack upon the "Pioneer's" boats. We anchored on the Great Luabo mouth of the Zambesi, because wood was much more easily obtained there than at the Kongone.
