From February to October Speke had the most trying experiences which were to await him on this journey. He travelled backwards and forwards from Kaze to Uzinza, endeavouring in all possible ways to get porters to carry him to Usui. In these journeys he caught a severe cold, the effects of which lasted for months in a most distressing cough, and some disease of the chest which he could not diagnose. His caravans were robbed, though the goods were sometimes recovered. Several of his Swahili headmen turned traitors; Bombay alone was faithful. Grant, when he had recovered from fever, marched and countermarched. But Speke had fortunately managed months before to send on word of his coming to Suwarora, Chief of Usui, who himself was a vassal of Rumanika, the great Hima ruler of Karagwe. Suwarora sent an envoy with his mace to invite Speke to proceed at once to his court. This intervention made a good impression on the treacherous chief of Buzinza, Lumeresi. Much of the stolen property was recovered, and the expedition obtaining a few porters started for Usui in October, 1861. Grant was left behind with such of the property as could not be removed. Speke, when he left Buzinza, “was a most miserable spectre in appearance, puffing and blowing at each step he took, with shoulders drooping and left arm hanging like a dead log, which he was unable to swing.” At last, after incredible worries and trouble, occasioned by the demands for “hongo” (tribute) on the part of every petty chief whose territories they crossed, they reached the large country of Usui or Busui at the southwest corner of the Victoria Nyanza. Usui is “a most convulsed looking country of well-rounded hills composed of sandstone.... Cattle were numerous, kept by the Wahuma (Bahima), who would not sell their milk to us because we ate fowls and a bean called _maharagwe_.” In Usui the caravan was incessantly worried at night by the attacks of thieves until one of these was killed, whereupon the Basui congratulated the expedition, saying that the slain man was a wonderful magician. “They thought us wonderful men, possessed of supernatural powers.” Suwarora and his fellow-chief Vikora were most exacting in their demands for hongo. At last, after heart-breaking delays, they got away out of Suwarora’s country.
