I gave him two cloths and a double blanket as a present.

He discovered afterwards what he knew before, that all had been injured by the wet on the way here, and sent two back openly, which all saw to be an insult.

He asked a little coffee, and I gave a plateful; and he even sent again for more coffee after I had seen reason to resent his sending back my present.

I replied, "He won't send coffee back, for I shall give him none." In revenge he sends round to warn all the Ujijians against taking my letters to the coast; this is in accordance with their previous conduct, for, like the Kilwa people on the road to Nyassa, they have refused to carry my correspondence.
This is a den of the worst kind of slave-traders; those whom I met in Urungu and Itawa were gentlemen slavers: the Ujiji slavers, like the Kilwa and Portuguese, are the vilest of the vile.

It is not a trade, but a system of consecutive murders; they go to plunder and kidnap, and every trading trip is nothing but a foray.
