Sessé Island extends from a point six miles south of Kibonga, westward to a point seven miles south of Jumba’s village, and southward—parallel almost with the coast of Uddu—to a distance of about twenty-three miles. Its extreme length is about forty-two miles, while its extreme breadth must be about twenty miles. The principal canoe builders and the greater number of the sailors of Mtesa’s empire dwell in Sessé, and because of their coal-black colour, timidity, superstition, and general uncleanly life, are regarded as the helots of Uganda. _April 21._—On the 21st we made a tedious, eventless voyage along the low, swampy, and jungly shores of Ujaju to Dumo, a village situated on the mainland nearly opposite the extreme southern end of Sessé Island. From a curious stony hill near Dumo, which bears traces of ancient effects of water, we obtained a distant view of the outskirts of a pastoral plateau rising westward. Magassa appeared in the evening from his unsuccessful quest for canoes. He gave a graphic account of the dangers he had encountered at Sessé, whose inhabitants declared they would rather be beheaded by the _Kabaka_ than risk themselves on an endless voyage on the stormy sea, but he had obtained a promise from Magura, the admiral in charge of the naval yards at Sessé, that he would endeavour to despatch fourteen canoes after us. Meanwhile, Magassa had left me at Chiwanuko with five canoes, but returned with only two, alleging that the other three leaked so much that they were not seaworthy. He suggested also that, as Magura might cause great delay if left alone, I should proceed with Sentum and Sentageya, and leave him in charge of five. Having witnessed his vanity and heard of his atrocious conduct near Chiwanuko, I strongly suspected him of desiring to effect some more mischief at Dumo, but I was powerless to interpose the strong arm, and therefore left him to answer for his shortcomings to Mtesa, who would doubtless hear of them before long.
