The next day was a march of eight miles, from East Mvumi to West Mvumi, where lived the Sultan of the district. The quantity and variety of provisions which arrived at our boma did not belie the reports respecting the productions of Ugogo. Milk, sour and sweet, honey, beans, matama, maweri, Indian corn, ghee, pea-nuts, and a species of bean-nut very like a large pistachio or an almond, water-melons, pumpkins, mush-melons, and cucumbers were brought, and readily exchanged for Merikani, Kaniki, and for the white Merikani beads and Sami-Sami, or Sam-Sam. The trade and barter which progressed in the camp from morning till night reminded me of the customs existing among the Gallas and Abyssinians. Eastward, caravans were obliged to despatch men with cloth, to purchase from the villagers. This was unnecessary in Ugogo, where the people voluntarily brought every vendible they possessed to the camp. The smallest breadth of white or blue cloth became saleable and useful in purchasing provisions--even a loin-cloth worn threadbare. The day after our march was a halt. We had fixed this day for bearing the tribute to the Great Sultan of Mvumi. Prudent and cautious Sheikh Thani early began this important duty, the omission of which would have been a signal for war. Hamed and Thani sent two faithful slaves, well up to the eccentricities of the Wagogo sultans--well spoken, having glib tongues and the real instinct for trade as carried on amongst Orientals. They bore six doti of cloths, viz., one doti of Dabwani Ulyah contributed by myself, also one doti of Barsati from me, two doti Merikani Satine from Sheikh Thani, and two doti of Kaniki from Sheikh Hamed, as a first instalment of the tribute. The slaves were absent a full hour, but having wasted their powers of pleading, in vain, they returned with the demand for more, which Sheikh Thani communicated to me in this wise: "Auf! this Sultan is a very bad man--a very bad man indeed; he says, the Musungu is a great man, I call him a sultan; the Musungu is very rich, for he has several caravans already gone past; the Musungu must pay forty doti, and the Arabs must pay twelve doti each, for they have rich caravans. It is of no use for you to tell me you are all one caravan, otherwise why so many flags and tents? Go and bring me sixty doti, with less I will not be satisfied."
