At five o’clock we again advance to the south, for the natives do not shew themselves. On the left we notice one, and on the right two, lakes. We see, from the mast, at the distance of a quarter of an hour, a lake of an hour long, and half of that in breadth; and some hundred paces at the side of the left shore, a lake, not broad, but, judging from the green grass, about two hours’ long. Behind, towards the west, another lake shews itself, on the margin of which the Haba recedes about an hour and a half; and behind us also, on the left shore, a third lake to N.W. In front, towards S.S.W., a lake, behind which another, in S.S.W., in the obtuse angle formed by the river there to the right shore; therefore, at one glance we observed _five lakes_ on the left shore, joining, very certainly, at high-water, and taking up an enormous space. There is no tree to be seen on the left to announce the far-distant right shore; yet a margin of wood shews itself in the distance on the left from E.S.E. to W. The air appears to be clearer, for I see the smoke, in many places, ascending straight up. At sunset we have the lake at our side, which lies, at five o’clock, S.S.W. of us, and behind it another strip of water flashes up in the south. From S. we go again in a semicircle to E. and N.E., and immediately again southward. We sail, indeed, since five o’clock, but have made, deducting the water-course, which has gradually got up again to a mile in rapidity, scarcely half a mile in the hour. At seven o’clock, E.N.E., and at eight o’clock S. by E., and soon afterwards from W.S.W. to S. and S.E. to E., from E. to S.W., E.S.E., and N.E., sometimes with the sails, sometimes libàhn, equally quick, for the north wind is very slack. In the level extensive arch, S. by W. to S.S.W., at last we halt at the corner, where the river winds to N.E. A large lake twinkles here on the left shore. The river retains, generally, a breadth of about five hundred paces; its depth is here two fathoms and a half. This seldom amounts to more than three, and was to-day, in one part, only two fathoms. Nevertheless, the river always contains a large quantity of water, for the shores, precipitous and deep, nearly fall away in a right angle. It is surprising that we have not yet found a flint, or any other stone, in the Nile sand. The Mountains of the Moon must therefore be still far distant from us. The thermometer, at sunrise, 20°, at ten o’clock 26°, at twelve o’clock 27°, and rose till three o’clock to 29°. After sunset, 26°, a heat too great for me, as I was not well; although I had borne, at Khartùm, on the shores of the Blue river, a heat of 42° to 45° throughout the hot days; and was subsequently to endure, in the city of Sennaar, for three days, at three o’clock in the afternoon, 48° Reaumur.
