As Sharp had shot a brace of hippo in our pool, we had them dragged out on to the sandbank opposite, and built a grass screen at the lower end of the hippo tunnel which led down through the bush from the high ground above the river. Fortunately, as it afterwards transpired, we took the precaution to block up the top entrance with stones. Here Sharp and I posted ourselves for the night in hopes of lions. When all was quiet, scores of vast crocodiles came out of the pool, and so successfully did they rend and tear the huge carcases that in the morning nothing remained but a few bones. It was a gruesome sight, the great loathsome reptiles tearing vast blocks of hide like brown paper, then crawling away to digest their morsel, then again advancing to the attack, while a row of hyænas sat silhouetted against the sky on the high bank opposite, or trotted uneasily to and fro, moaning and howling unceasingly, yet fearing to approach the evil mass of reptiles. Crowds of mosquitoes and sandflies added their plaintive song. Suddenly with a mighty rush five hippo dashed down the bank, then, recovering from their alarm, strolled quietly by at five yards, the moonlight gleaming white on their wet backs. Having heard some lions at sunrise to the east I started in pursuit, and, following along an extensive dry donga that cut through the plain, found some fresh spoor which I lost in the endless sea of dry long grass that covered the greater part of the plain. This I fired, and then came round by the river, hoping to see some of them if they were driven from their cover. When nearly home I saw a lion stand up in the low scrub about a thousand yards away. He had our wind, and started across the bare plain at a gallop, making for the long grass. I set off in hot pursuit with my gun-boy. When the lion stopped to look I stopped, hoping that he would think I was not following him. Whereupon my boy, who would never learn the trick, sailed gracefully over my shoulder. The lion, apparently taking us for some harmless mountebanks, slackened his pace, and only reached the grass about five hundred yards ahead of me. Rushing in on his tracks, I was fortunate enough to catch a glimpse of his mane above the grass, as he crossed a place where the grass was rather shorter than elsewhere. He had turned at right angles from his course, and had ceased to worry himself about me. Following hard, I got a chance at sixty yards, and knocked him over with a shot from the .500 magnum high on the shoulder. Owing to the smoke, the lack of landmarks, and the height of the grass (about 4 ft. 6 in.), I lost his exact whereabouts, and after slipping in another cartridge, walked past him. He suddenly rose at twenty-five yards and charged straight. The incredible rapidity of his onslaught and the cover afforded by the grass rendered aiming impossible. I merely swung the gun on him and dropped him at four yards with a shot in the neck, then hastily retired. After
