Every doubt is removed, after considerable questioning of the natives; we return a quarter before five o’clock from this ascent, and stop above the Kièhr, which we had come up from the White Nile, in order to examine it, even to its issue, and had taken hitherto for an independent mountain stream. At six o’clock we go to the neighbouring island, between the Nile and the gohr Kièhr. At sunset 29°; this will be a hot night. _11th February._—We remain near the large island of Tui, make a section of the Nile, and find the main stream below the bay, where it divides into three arms, a hundred and twenty-eight mètres broad. It is called here Landofò; the Kokis inhabit its left shore. The Liénns possess the right, together with our island, and the shores of the gohrs, between which is the island of Tobo. Only a few of the latter tattoo the forehead; some, the shoulders, as far as the upper part of the arm; and others, the upper part of the back: some have also coloured themselves with ochre. _12th February_—Observations are to be made also to-day, in order to start in the afternoon. I purchase for a few large glass beads, the first _fine_ elephant’s tooth, and I design it, being the largest of all, as a cabinet specimen for my country. Now, at last, it is evident to every one, that we are navigating back our old road. It is fortunate for me that I am able to set up continuously and write my journal, affected as I am with fever all the day after the hot nights. At half-past two o’clock we bear off, and reach at half-past four the end of the island of Tobo, near which we land at sunset by the left shore, having made four miles and a half with a strong current, and the stroke of the oar. Thermometer, in the morning, 20°; noon, 32°; evening, 30°. _13th February._—We are to set out half an hour after sunrise; in the meantime the men are slaughtering in haste some cows, which natives of uncommon size have brought us. We do not proceed, therefore, till seven o’clock, in a north-westerly direction. The river makes such short bends that we bound every moment against the shore, notwithstanding the very strong fall, and we tear off also a corner of the loose earth. This, as well as the carelessness in steering, causes the vessel to draw water continually. Nine o’clock. We stop at the left shore, near some dome-palms; the water is a little deeper here, as if a broad arm of the Nile, from E.S.E., joins with our narrow one, or we with it. Here also they bring us cotton for sale. Eleven o’clock. We go on with a favourable east wind. The tokuls for dwellings are the peristyles already described. At noon we see several hippopotami, some of them real monsters; these may remain here pretty constantly, being perhaps their hunting district, because the river is, on the whole, of great depth in this place.
