At 7 A. M. they drew near Nyambwa, where excellent water was found. The villagers here crowded around them with shouts and yells, and finally became so insolent that Stanley grabbed one of them by the neck and gave him a sound thrashing with his donkey-whip. This enraged them, and they walked backward and forward like angry tom-cats, shouting, "Are the Wagogo to be beaten like slaves?" and they seemed by their ferocious manner determined to avenge their comrade, but the moment Stanley raised his whip and advanced they scattered. Finding that the long lash, which cracked like a pistol, had a wholesome effect, whenever they crowded upon him so as to impede his progress, he laid it about him without mercy, which soon cleared a path. The Sultan Kimberah was a small, queer and dirty old man, a great drunkard, and yet the most powerful of all the Ugogo chiefs. Here they had considerable trouble in arranging the amount of tribute, but at length everything was settled and the caravan passed on and entered on a vast salt plain containing a hundred or more square miles, from the salt springs of which the Wagogo obtained their salt.

Early in the morning he began to take his quinine, and kept repeating the doses at short intervals until a copious perspiration told him he had broken the fever which had been consuming him for fourteen days. During this time, the sultan of the district, attracted by Stanley's lofty tent, with the American flag floating above it, visited him. He was so astonished at the loftiness and furnishing of the tent, that in his surprise he let fall the loose cloth that hung from his shoulders and stood stark naked in front of Stanley, gaping in mute wonder.

On the 4th of June, the caravan was started forward again, and after three hours' march it came upon another district, containing only two villages occupied by pastoral Wahumba and Wahehe. These live in cow-dung cone huts, shaped like Tartar tents. Stanley says:
