We left Tete at noon on the 22d, and in the afternoon arrived at the garden of Senhor A. Manoel de Gomez, son-in-law and nephew of Bonga. The Commandant of Tete had sent a letter to the rebel Bonga, stating that he ought to treat me kindly, and he had deputed his son-in-law to be my host. Bonga is not at all equal to his father Nyaude, who was a man of great ability. He is also in bad odor with the Portuguese, because he receives all runaway slaves and criminals. He does not trust the Portuguese, and is reported to be excessively superstitious. I found his son-in-law, Manoel, extremely friendly, and able to converse in a very intelligent manner. He was in his garden when we arrived, but soon dressed himself respectably, and gave us a good tea and dinner. After a breakfast of tea, roasted eggs, and biscuits next morning, he presented six fowls and three goats as provisions for the journey. When we parted from him we passed the stockade of Bonga at the confluence of the Luenya, but did not go near it, as he is said to be very suspicious. The Portuguese advised me not to take any observation, as the instruments might awaken fears in Bonga's mind, but Manoel said I might do so if I wished; his garden, however, being above the confluence, could not avail as a geographical point. There are some good houses in the stockade. The trees of which it is composed seemed to me to be living, and could not be burned. It was strange to see a stockade menacing the whole commerce of the river in a situation where the guns of a vessel would have full play on it, but it is a formidable affair for those who have only muskets. On one occasion, when Nyaude was attacked by Kisaka, they fought for weeks; and though Nyaude was reduced to cutting up his copper anklets for balls, his enemies were not able to enter the stockade.
On the 24th we sailed only about three hours, as we had done the day before; but having come to a small island at the western entrance of the gorge of Lupata, where Dr. Lacerda is said to have taken an astronomical observation, and called it the island of Mozambique, because it was believed to be in the same latitude, or 15d 1', I wished to verify his position, and remained over night: my informants must have been mistaken, for I found the island of Mozambique here to be lat. 16d 34' 46" S.
