The Second Cataract has a total descent of sixty feet, and is about nine miles long. For this distance the Nile flows down a rugged stairway formed by successive ledges of black granite. The flood river deeply submerges these steps, and rushes along above them with tremendous force, but with a smooth though swirling surface. As the Nile subsides, the steps begin to show, until the river tumbles violently from ledge to ledge, its whole surface for miles churned to the white foam of broken water, and thickly studded with black rocks. At the Second Cataract, moreover, the only deep channel of the Nile is choked between narrow limits, and the stream struggles furiously between stern walls of rock. These dark gorges present many perils to the navigator. The most formidable, the Bab-el-Kebir, is only thirty-five feet wide. The river here takes a plunge of ten feet in seventy yards, and drops five feet at a single bound. An extensive pool above, formed by the junction of two arms of the river, increases the volume of the water and the force of the stream, so that the 'Gate' constitutes an obstacle of difficulty and danger which might well have been considered insurmountable. It had been expected that in the beginning of July enough water would be passing down the Second Cataract to enable the gunboats and steamers waiting below to make the passage. Everything depended upon the rise of the river, and in the perversity of circumstances the river this year rose much later and slower than usual. By the middle of August, however, the attempt appeared possible. On the 14th the first gunboat, the Metemma, approached the Cataract. The North Staffordshire Regiment from Gemai, and the 6th and 7th Egyptian Battalions from Kosheh, marched to the 'Gate' to draw the vessel bodily up in spite of the current. The best native pilots had been procured. Colonel Hunter and the naval officers under Commander Colville directed the work. The boat had been carefully prepared for the ordeal. To reduce, by raising the free-board, the risk of swamping, the bows were heightened and strengthened, and stout wooden bulwarks were built running from bow to stern. Guns and ammunition were then removed, and the vessel lightened by every possible means. A strop of wire rope was passed completely round the hull, and to this strong belt the five cables were fastened--two on each side and one at the bow. So steep was the slope of the water that it was found necessary to draw all the fires, and the steamer was thus dependent entirely upon external force. It was luckily possible to obtain a direct pull, for a crag of black rock rose above the surface of the pool opposite the 'Gate.' On this a steel block was fixed, and the hawser was led away at right angles until it reached the east bank, where a smooth stretch of sand afforded a convenient place for the hauling parties. Two thousand men were then set to pull at the cables, yet such was the
