Leaving Bagamoyo for the interior.--Constructing a Bridge.-- Our first troubles.--Shooting Hippopotami.--A first view of the Game Land.--Anticipating trouble with the Wagogo.--The dreadful poison--flies.--Unlucky adventures while hunting.-- The cunning chief of Kingaru.--Sudden death of my two horses.--A terrible experience.--The city of the "Lion Lord." On the 21st of March, exactly seventy-three days after my arrival at Zanzibar, the fifth caravan, led by myself, left the town of Bagamoyo for our first journey westward, with "Forward!" for its mot du guet. As the kirangozi unrolled the American flag, and put himself at the head of the caravan, and the pagazis, animals, soldiers, and idlers were lined for the march, we bade a long farewell to the dolce far niente of civilised life, to the blue ocean, and to its open road to home, to the hundreds of dusky spectators who were there to celebrate our departure with repeated salvoes of musketry. Our caravan is composed of twenty-eight pagazis, including the kirangozi, or guide; twelve soldiers under Capt. Mbarak Bombay, in charge of seventeen donkeys and their loads; Selim, my interpreter, in charge of the donkey and cart and its load; one cook and sub, who is also to be tailor and ready hand for all, and leads the grey horse; Shaw, once mate of a ship, now transformed into rearguard and overseer for the caravan, who is mounted on a good riding-donkey, and wearing a canoe-like tepee and sea-boots; and lastly, on, the splendid bay horse presented to me by Mr. Goodhue, myself, called Bana Mkuba, "the big master," by my people--the vanguard, the reporter, the thinker, and leader of the Expedition.
