After a two days’ rest at Kiryama we marched south across the grassy plain to another ferry led by Kaibuga. That which some of us had assumed to be a lake was very firm alluvium and lacustrine deposit, growing a thin crop of innutritious grass, about 18 inches high. As we advanced up the river it sensibly improved; and at the third hour from Kiryama an acacia tree was seen; a little later there were five, then a dozen, wide apart and stunted. At the fourth hour it was quite a thin forest on the left side of the Semliki, while to the right it was a thick impervious and umbrageous tropic forest, and suddenly we were on the bank of the Semliki. At the point we touched the river it was sixty yards wide, with between a four and five-knot current. A little below it widened into 100 yards, a fine, deep, and promising river. Up and down, and opposite, there were broad signs of recent land falls. Its banks consisted of sediment and gravelly débris which could offer no resistance to the strong current when it surged against the base. It washed away great masses from underneath. There was a continual falling of dissolving lumps, as though it was so much snow; then a sudden fall of a two-ton fragment of the superincumbent bank. It was a loopy, and twisting, crooked stream, forming a wide-stretching S in every mile of its course, and its water was of a whitey-brown colour, and weighted with sediment. Out of a tumblerful of the liquid, a fourth of an inch of fine earth would be deposited. By a good aneroid the altitude of the bank, which was about twenty feet above the river, was 2,388 feet above the sea. Lake Albert by the same aneroid was 2,350 feet. There was a difference indicated of 38 feet. I estimated that we were about thirty English miles from the lake.
