deep, and the same depth was kept to within a few hundred yards of the principal mouth of the Rusizi.  The current was very sluggish; not more than a mile an hour.  Though we constantly kept our binocular searching for the river, we could not see the main channel until within 200 yards of it, and then only by watching by what outlet the fishing; canoes came out.  The bay at this point had narrowed from two miles to about 200 yards in breadth.  Inviting a canoe to show us the way, a small flotilla of canoes preceded us, from the sheer curiosity of their owners.  We followed, and in a few minutes were ascending the stream, which was very rapid, though but about ten yards wide, and very shallow; not more than two feet deep.  We ascended about half a mile, the current being very strong, from six to eight miles an hour, and quite far enough to observe the nature of the stream at its embouchure.  We could see that it widened and spread out in a myriad of channels, rushing by isolated clumps of sedge and matete grass; and that it had the appearance of a swamp.  We had ascended the central, or main channel.  The western channel was about eight yards broad.  We observed, after we had returned to the bay, that the easternmost channel was about six yards broad, and about ten feet deep, but very sluggish.  We had thus examined each of its three mouths, and settled all doubts as to the Rusizi being an effluent or influent.  It was not necessary to ascend higher, there being nothing about the river itself to repay exploration of it.

The question, “Was the Rusizi an effluent or an influent?” was answered for ever.  There was now no doubt any more on that point.  In size it was not to be compared with the Malagarazi River, neither is it, or can it be, navigable for anything but the smallest canoes.  The only thing remarkable about it is that it abounds in crocodiles, but not one hippopotamus was seen; which may be taken as another evidence of its shallowness.  The bays to the east of the Rusizi are of the same conformation as those on the west.  Carefully judging from the width of the several bays from point to point, and of the several spits which separate them, the breadth of the lake may be said to be about twelve or fourteen miles.  Had we contented ourselves with simply looking at the conformation, and the meeting of the eastern and western ranges, we should have said that the lake ended in a point, as Captain Speke has sketched it on his map.  But its exploration dissolved that idea.  Chamati Hill is the extreme northern termination of the western range, and seems, upon a superficial examination, to abut against the Ramata mountains of the eastern range, which are opposite Chamati; but a valley about a mile in breadth separates the two ranges, and through this valley the Rusizi flows towards the lake.* Though Chamati terminates the western range, the eastern range continues for miles beyond, north-westerly.  After its issue from this broad gorge, the Rusizi runs seemingly in
