We had now no other resource left us but to proceed with the investigation of the lake in common canoes; for we could not wait any longer, as our supplies were fast on the wane. I was sorry for it, as my companion was still suffering so severely, that anybody seeing him attempt to go would have despaired of his ever returning. Yet he could not endure being left behind. Travelling in canoes, as I could now testify from my late experiences, is, without joke, a very trying business to a sick man, even in the best weather; and here we were still in the height of the monsoon. Negotiations for the means of carrying out our object (of proceeding to the north of the lake, surveying it, and ascertaining whether Hamed's story about a large river running out of it was based upon a true foundation) were then commenced, and Kannina was applied to. He likewise, it appeared, had a plan in view of carrying on some ivory transactions with the Sultan of Uvira, governing a district at the northern end and western shore of the lake, and agreed to take us there, and also show us the river in question. It was settled that we should go in two canoes; Captain Burton, with Kannina, in a very large one, paddled by forty men at once, and I in another considerably smaller--our party to pay all expenses; and, in fact, to do Kannina's business in consideration of his protection. This we did do, and no more; for, after arriving at Uvira, nothing could induce him to take us to the river at the end of the lake, although the remaining distance could have been accomplished in about six hours' paddling. His reason, which he must have known before, was, that the savages resident there, the Warundi tribe, were inimical to his people, the Wajiji. This was a sore disappointment, though not so great as it would have been had we not ascertained that Hamed's story was a mere fabrication. He had never been to the north end of the lake, nor had he had the fight he described with the natives; and, moreover, Bombay assured both Captain Burton and myself that Hamed really meant that the river ran into the lake. Had I thought of it, I should then have changed the course of the Marungu river on my map, and made it run out of the lake, but I did not. Next the sultan's son, who visited us immediately on our arrival at Uvira, told us that the river, which is named Rusizi, drained the high mountains encircling our immediate north, and discharged its waters into the lake. I should not have been satisfied with this counter-statement alone, had I not ascended some neighbouring heights, and observed the mountains increasing in size as they extended away to the northward, and effectually closing in this _low_ lake, which is not quite half the altitude of the surface-level of the general interior plateau. Although wrong in most respects, Hamed was right about the distance the lake's northern end lay from Ujiji; for, properly divided, it takes eight days, the time he specified, exactly.
