The lad did as he was bid. But in order to get well behind the covey of guinea-fowl, which are dreadful things to run, he made a little circuit through the thickest part of the clump. As he did so his quick eye was arrested by a most unusual performance on the part of one of the flat-crowned mimosa-trees. Suddenly, and without the slightest apparent reason, it rose into the air, and then, behold! where its crown had been a moment before, appeared its roots. Such an “Alice in Wonderland” sort of performance on the part of a tree could not but excite the curiosity of an intelligent youth. Accordingly, Roger pushed forwards, and slipped round an intervening tree. This was what he saw: In a little glade about ten paces from him, flapping its ears, stood an enormous elephant with great white tusks, looking as large as a house and as cool as a cucumber. Nobody, to look at the brute, would have believed that he had given them a twenty miles’ trot under a burning sun. He was now refreshing himself by pulling up mimosa-trees as easily as though they were radishes, and eating the sweet fibrous roots. Roger saw this, and his heart burned with ambition to kill that elephant—the mighty great beast, about a hundred times as big as himself, who could pull up a large tree and make his dinner off the roots. Roger was a plucky boy, and, in his sportsmanlike zeal, he quite forgot that a repeating carbine is not exactly the weapon one would choose to shoot elephants with. Indeed, without giving the matter another thought, he lifted the little rifle, aimed it at the great beast’s head, and fired. He hit it somewhere, that was very clear, for next moment the air resounded with the most terrific scream of fury that it had ever been his lot to hear. That scream was too much for him; he turned and fled swiftly. Elephants were evidently difficult things to kill. Fortunately for Roger, the elephant could not for some seconds make out where his tiny assailant was. Presently, however, he winded him, and came crashing after him, screaming shrilly, with his trunk and tail well up. On hearing the shot and the scream of the elephant, Ernest, who was standing some way out in the open, in anticipation of a driving shot at the guinea-fowl, had run towards the spot where Roger had entered the bush; and, just as he got opposite to it, out he came, scuttling along for his life, with the elephant not more than twenty paces behind him. Then Ernest did a brave thing. [Illustration: “Ernest did a brave thing.”]
