start again, and in an hour cross the mouth of the little river Hebué. Unfortunately these streams add nothing to the beauty of the scenery; and were it not for the gaps in the hills suggesting the probable course of rivers, they might be passed without notice, for the mouths are always concealed by bulrushes, or other tall aquatic reeds; and inland they are just as closely hidden by forest vegetation. In half an hour more we enter a small nook called Luguvu Khambi, very deep, and full of crocodiles and hippopotami. On landing, we fire the usual alarm-guns--a point to which our captain is ever strictly attentive--cook our dinners, and turn in for the night. Here I picked up four varieties of shells--two univalves and two bivalves--all very interesting from being quite unknown in the conchological world. There were numbers of them lying on the pebbly beach. 7th.--We started at dawn as usual; but again at sunrise, the wind increasing, we put in for the shore, for these little cranky boats can stand no sea whatever. Here a herd of wild buffaloes, horned like the Cape ones, were seen by the men, and caused some diversion: for, though too blind myself to see the brutes at the distance that the others did, I loaded and gave them chase. Whilst tracking along, I saw fresh prints of elephants, which, judging from their trail, had evidently just been down to drink at the lake; and sprang some antelopes, but could not get a shot. The sea going down by noon, we proceeded, and hugged a bluff shore, till we arrived at Insigazi, a desert place, a little short of Kabogo, the usual crossing-point. Although the day was now far advanced, the weather was so promising, whilst our stores were running short, that impatience suggested a venture for the opposite shore to Kivira, an island near it, and which, with the Uguhha heights in the background, is from this distinctly visible. This line is selected for canoes to cross at, from containing the least expanse of water between the two shores, between Ujiji and the south end. The Kabogo Island, which stands so conspicuously in the missionaries' map that hung on the Royal Geographical Society's walls in 1856, is evidently intended for this Kabogo or starting-point, near which we now are, and is so far rightly placed upon their map as representing the half-way station from Ujiji to Kasengé, two places on opposite sides of the lake, whither the Arab merchants go in search of ivory. For Kabogo, as will be seen by my map, lies just midway on the line always taken by boats travelling between those two ports--the rest of the lake being too broad for these adventurous spirits. In short, they coast south from Ujiji to Kabogo, which constitutes the first half of the journey, and then cross over.
