Tribe after tribe was passed, some of which had not been seen on the ascent, because the steamers were constantly seeking out new channels. Whenever it was deemed politic, stops were made and treaties entered into. All on board suffered much from the river breezes, heightened by the velocity of the steamers. These breezes checked perspiration too suddenly, and some severe prostrations occurred. By Christmas the flotilla was back to Iboko, where thieving was so rampant as to necessitate the seizure of one of the offenders and his imprisonment in a steamer. The chief, Kokoro, came alongside in a canoe to commend Stanley for ridding the tribe of a fellow who could bring such disgrace upon it; and he was really very earnest in his morality till he looked in upon the prisoner and found it was his son. Then there was lamentation and offers to buy the boy back. Stanley’s terms were a restitution of the stolen articles, and these not being met, he sailed away with the offender, promising to return in ten days to insist upon his conditions. [Illustration: RECEPTION BY AN AFRICAN KING.] The populous districts of Usimbi and Ubengo were passed. At Ukumiri the whole population came out to greet the steamers, as it did at Bungata and Uranga. As many of these places had not been visited on the upward journey, it was manifest that word of the treaties and the impression made were being gradually and favorably disseminated by the canoe-traders. Equator Station was found in a flourishing condition. It was January 1st, 1884, when the steamers began an upward journey again to Iboko, in order to keep faith with Kokoro by returning his son. The old chief, Mata Bwyki, was indignant at the seizure of one of his subjects, but seeing that Stanley had returned and was acquainted with the tribal custom that a thief could be held till the stolen goods were restored, he fell in with his idea of justice, and went so far as to insist on a return of the stolen articles, or else the imprisonment which Stanley had inflicted. This attitude resulted in a restoration of the property and the temporary shame of the culprits.
