The piles were driven with some difficulty, and diagonal struts were fastened from the top of the front row to the base of the rear. Horizontal beams then secured the entire line of skeleton bridge.
For two days 1,500 men were employed in making fascines of long, thick reeds tied in large bundles, in the centre of which was concealed a mass of about fifty pounds of stiff clap. These bundles were firmly lashed with twisted rushes. I had 500 corn sacks filled with sand and clay, these were to form the foundation of the dam, and to prevent the water from burrowing beneath.
Every company of troops had to prepare a certain number of fascines, which were piled on the side of the river, which had now exposed solid banks overgrown with the high reedy grass. This immensely long and thick grass, resembling sugar-canes, was exactly the material that we required. It was this gratis that created natural obstructions, and would therefore assist us in our artificial obstruction or dam. The sailors of the fleet worked in divisions under separate officers.
On March 13, all the preparations were completed for the work of filling in the dam. Great piles of solid balls of clay, of about 40 lbs. each, had been arranged in convenient places to stop up any leaks that should occur.
I stood on one of the stranded boats only a few yards from the row of piles. The men were all in their places. The buglers and drummers stood upon another vessel ready to give the signal.
At the first bugle, every two men lifted the sacks of sand and clay. At once all the drums and bugles then sounded the advance, and 500 heavy sacks were dropped into the row of piles, and firmly stamped down by the men. The troops now worked with intense energy. It was a race between the Soudanis and the Egyptians; this was labour to which the latter were accustomed in their own country. The sailors worked as vigorously as the troops; piles of fascines and clay balls were laid with extraordinary rapidity, while some stamped frantically and danced upon the entangled mass, all screaming and shouting in great excitement, and the bugles and drums kept up an incessant din. A long double line of men formed a transport corps, and passed a never-failing supply of fascines to the workers who stood in the water and kneaded firmly the adhesive mass.
At 2.15 P.M. the river was completely shut in, and the people with increased energy worked at the superstructure of the dam, which now rose like a causeway for about one hundred and ten yards from shore to shore.
At 3.30 the water had risen to an extent that obliged the men in some places to swim. The steamer that had been hopelessly stranded, and the entire fleet, were floating merrily in the pond. Thank God, I had forgotten nothing in the preparatory arrangements for the expedition. Without the spades, hoes, grass-knives, bill-hooks, timber, &c., &c., we never could have succeeded in this journey.
My diahbeeah was in the lake waiting for the fleet to accomplish the passage. I had made an excursion one day in the dingy to examine the south end of the lake, which I found to be about eight miles in length. On returning, I was rather anxious for the small boat, as a bull hippopotamus made a hostile demonstration. The water was not more than five feet six inches deep; thus as the hippo, after having snorted and sunk, continued to approach the boat, I could distinguish the path of his advance by the slight wave raised upon the surface. He presently raised his head about twenty yards from the boat, but at the same time he received a Reilly explosive shell under the eye which ended his worldly cares.
There were many hippopotami in this lake, and, very shortly after I had killed the first, I shot a second much in the same manner. I always carried a harpoon in the boat with the rope and ambatch float. The latter was painted red, so that it could be easily observed. I therefore, stuck the harpoon in the dead hippopotamus as a mark, and hastened back to my diahbeeah for assistance, as the flesh of two hippopotami would be very welcome to the people, who had not received rations of butcher's meat for many weeks. On arrival at the diahbeeah we quickly made sail, and soon returned to the hippopotamus. By the time we had cut up this large animal and secured the flesh, the sun was so low that I considered it would be better to fasten the other hippo by a rope attached to the hind legs, and tow it bodily astern of the diahbeeah. It could then be divided on the following day.
In this manner we returned to our anchorage at the tail of the lake, close to the entrance of the new channel. By the time we arrived, the moon was up. The diahbeeah was close to a mud-bank covered with high grass, and about thirty yards astern of her was a shallow part of the lake about three feet deep. A light boat of zinc was full of strips of hippopotamus' flesh, and the dingy was fastened alongside.
After dinner and a pipe, the usual arrangements were made for the night. There were many servants, male and female, on board; these began to suspend their mosquito curtains to the rigging and to creep beneath; the sailors, after chatting for a considerable time, dropped off to sleepuntil the sentry was the only man on board who was on the alert. I always slept on the poop-deck, which was comfortably arranged with sofas and carpets.
The night was cold, and the moon clear and bright. Every one was wrapped up in warm blankets, and I was so sound asleep, that I cannot describe more until I was suddenly awoke by a tremendous splashing quite close to the diahbeeah, accompanied by the hoarse wild snorting of a furious hippopotamus. I jumped up, and immediately perceived a hippo which was apparently about to attack the vessel. The main deck being crowded with people sleeping beneath their thick mosquito curtains, attached to the stairs of the poop-deck, and to the rigging in all directions, rendered it impossible to descend. I at once tore away some of the ties, and awakened the sleepy people. My servant, Suleiman, was sleeping next to the cabin door. I called to him for a rifle. Before the affrighted Suleiman could bring the rifle, the hippopotamus dashed at us with indescribable fury. With one blow he capsized and sank the zinc boat with its cargo of flesh. In another instant he seized the dingy in his immense jaws, and the crash of splintered wood betokened the complete destruction of my favourite boat. By this time Suleiman appeared from the cabin with an unloaded gun in his hand and without ammunition. This was a very good man, but he was never overburdened with presence of mind; he was shaking so fearfully with nervousness, that his senses had entirely abandoned him. All the people were shouting and endeavouring to scare the hippo, which attacked us without ceasing with a blind fury that I have never witnessed in any animal except a bull-dog.
By this time I had procured a rifle from the cabin, where they were always kept fixed in a row, loaded and ready for action, with bags of breechloading ammunition on the same shelf.
The movements of the animal were so rapid as he charged and plunged alternately beneath the water in a cloud of foam and wave, that it was impossible to aim correctly at the small but fatal spot upon the head.
The moon was extremely bright, and presently, as he charged straight at the diahbeeah, I stopped him with a No. 8 Reilly shell. To my surprise, he soon recovered, and again commenced the attack.
I fired shot after shot at him without apparent effect. The diahbeeah rocked about upon the waves raised by the efforts of so large an animal; this movement rendered the aim uncertain. At length, apparently badly wounded, he retired to the high grass; there he lay by the bank, at about twenty-five yards' distance, snorting and blowing.
I could not distinguish him, as merely the head was above water, and this was concealed by the deep shadow thrown by the high grass. Thinking that he would die, I went to bed; but before this I took the precaution to arrange a white paper sight upon the muzzle of my rifle, without which, night shooting is very uncertain.
