"March 17.—The lake is about 2 1/2 miles long, and varies from 150 to 300 yards in width, with a mean depth of ten feet. I sent men ahead in the boat to explore the exit; they now report it to be closed by a small dam, after which we shall enter another lake. Thunder and clouds threatening in the southeast.
"About half-an-hour before sunset I observed the head of a hippopotamus emerge from the bank of high grass that fringed the lake. My troops had no meat—thus I would not lose the opportunity of procuring, if possible, a supply of hippopotamus beef. I took a Reilly No. 8 breechloader, and started in the little dingy belonging to the diahbeeah. Having paddled quietly along the edge of the grass for a couple of hundred yards, I arrived near the spot from which the hippopotamus had emerged.
"It is the general habit of the hippopotami in these marsh districts to lie in the high grass swamps during the day, and to swim or amuse themselves in the open water at sunset.
"I had not waited long before I heard a snort, and I perceived the hippopotamus had risen to the surface about fifty yards from me. This distance was a little too great for the accurate firing necessary to reach the brain, especially when the shot must be taken from a boat, in which there is always some movement. I therefore allowed the animal to disappear, after which I immediately ordered the boat forward, to remain exactly over the spot where he had sunk. A few minutes elapsed, when the great ugly head of the hippopotamus appeared about thirty paces from the boat, and having blown the water from his nostrils, and snorted loudly, he turned round and seemed astonished to find the solitary little boat so near him. Telling the two boatmen to sit perfectly quiet, so as to allow a good sight, I aimed just below the eye, and fired a heavy shell, which contained a bursting charge of three drachms of fine-grained powder. The head disappeared. A little smoke hung over the water, and I could not observe other effects. The lake was deep, and after vain sounding for the body with a boathook, I returned to the diahbeeah just as it became dark.
"March 18.—A heavy shower of rain fell, which lasted for an hour and a half. When the rain ceased, the day continued cloudy with variable wind. The body of the hippopotamus was discovered at daybreak floating near us, therefore all hands turned out to cut him up, delighted at the idea of fresh meat. There was about an acre of high and dry ground that bordered the marsh in one spot; to this the carcase of the hippopotamus was towed. I was anxious to observe the effects of the explosive shell, as it was an invention of my own that had been manufactured by Mr. Reilly, [*] the gunmaker, of London. This shell was composed of iron, covered with lead. The interior was a cast-iron bottle (similar in shape to a stoneware Seltzer water bottle); the neck formed a nipple to receive a percussion-cap. The entire bottle was concealed by a leaden coating, which was cast in a mould to fit a No. 8, or two-ounce rifle. The iron bottle contained three drachms of the strongest gunpowder, and a simple cap pressed down upon the nipple prepared the shell for service.
[*Footnote: Mr. Reilly, of 502 New Oxford Street, has been most successful in heavy rifles, with which he has supplied me in both my African expeditions.]
"On an examination of the head of the hippopotamus, I found that the shell had struck exactly beneath the eye, where the bone plate is thin. It had traversed the skull, and had apparently exploded in the brain, as it had entirely carried away the massive bone that formed the back of the skull. The velocity of the projectile had carried the fragments of the shell onwards after the explosion, and had formed a sort of tunnel which was blackened with burnt powder for a considerable distance along the flesh of the neck. I was quite satisfied with my explosive shell.
"The hippopotamus having been divided among the men, I sent Raouf Bey with a large force to assist the steamers, which still remain fixed in the same spot.
"At 2 p.m. it poured with rain until 9 p.m. Everything is soaking; and I have great anxiety about our large stores of corn.
"March 19.—Fine day, but all cargo, stores, &c., are wet. The miserable vessels of the Soudan are without decks, thus one heavy shower creates much damage. The men are busy drying their clothes, &c. Two soldiers died. Steamers far astern in the sudd, regularly fixed.
