In the mean time, the troops at the vessels, that were within about 300 paces, having heard the rapid and continued firing, supposed that I had been attacked by the natives. The "Forty Thieves" rushed to the rescue. I heard the bugle, and presently the voices of the men as they approached, running through the bush at full speed. The hippopotamus had moved from his thorny retreat, and was walking slowly forward, when he was stumbled against by "The Forty," some of whom literally ran against him. The animal appeared quite stunned and stupid, and he merely stood and stared at his new assailants. The sight was perfectly ridiculous. Every rifle was fired into him; but the hollow bullets of the sniders had no penetration, and we might as well have peppered the stone bulls of Nineveh, in the British Museum. At length, after having been the centre of a blaze of fireworks, as every man did his best to kill him during the space of about a minute, he coolly approached the edge of the cliff, which was quite perpendicular and about eighteen feet high. A tremendous splash was the end of the encounter, as the hippo committed himself to the deep, with a clumsy jump from the midst of the disappointed soldiers. I was constantly annoyed by the want of penetration of the Boxer hollow bullets. The "Dutchman" carried three drachms of No. 6-grain powder, which should have driven a solid bullet through a large antelope; but the hollow Boxer projectile invariably disappeared in small fragments upon striking a bone; or it expanded, and had no further penetrating power after striking a thick hide. The sniders, although admirable military weapons, possessed a very small power of penetration. I have frequently seen the bodies of natives with only one bullet-mark; and I have extracted bullets that ought to have passed completely through. My "Forty Thieves" were now proud of themselves as experienced in various sports, and they were terribly disgusted at the escape of the hippopotamus. They were never idle for a single day. If no other work was on hand, I practised them at the target, or they were treated to a few hours' drill. Sometimes I took them fishing: this was always a great amusement, as the expedition was well furnished with nets.
