"We … entered the rich flat district of Mininga, where the gingerbread-palm grows abundantly. The greatest man we found here was a broken-down ivory-merchant called Sirboko, who gave us a good hut to live in. … one of Sirboko's slaves, chained up by him, in the most piteous manner cried out to me, "Hai Bana wangi, Bana wangi (Oh, my lord, my lord), take pity on me! When I was a free man I saw you at Uvira, on the Tanganyika Lake, when you were there; but since then the Watuta, in a fight at Ujiji, speared me all over and left me for dead, when I was seized by the people, sold to the Arabs, and have been in chains ever since. Oh, I say, Bana wangi, if you would only liberate me I would never run away, but would serve you faithfully all my life." This touching appeal was too strong for my heart to withstand, so I called up Sirboko, and told him, if he would liberate this one man to please me, he should be no loser; and the release was effected. He was then christened Farhan (Joy), and was enrolled in my service with the rest of my freed men."--Speke, loc. cit., referring to 1861
