In another half hour, during which time they got no shot, Juno, the pointer, became curiously restless. She seemed to neglect the sport in front of her, and turned perpetually to sniff the breeze which blew from their left flank. Suddenly, after quartering the ground in that direction, she stopped and barked furiously. "What’s the old girl up to?" ejaculated Tom. "I’ll go and see." As he turned his horse that way, the pointer, hitherto standing with hackles up, manifestly in a state of intense anger, suddenly turned and fled, her tail between her legs. Guy Hardcastle, curious to know what had so alarmed the dog, walked his nag that way. The two cousins rode on together for thirty yards, and then, with a curious hissing sound, there rose, ten paces in front of them, the head and neck of an enormous serpent. The reptile reared itself so suddenly, and its aspect was so menacing, that Guy’s pony shied violently and swerved off, nearly unseating its rider as it did so. "Look out, Guy!" cried his cousin. "It’s a python. Canter away a bit and slip in louper cartridges [buck shot], and then we’ll have a go at the brute. He’s been following us." They cantered away forty or fifty yards, changing their cartridges as they did so, and then returned to the charge. Meanwhile the python, which had undoubtedly been stalking them, had thought better of it, and, seeing more formidable quarry than it had bargained for, was slipping away. The lads galloped to the spot where they had last seen it; and Tom, pointing to a movement in the long grass in front of them, exclaimed excitedly, "There it goes; come on!" Guy, who was not used to snakes, didn’t half like the idea of stalking such a monster; but as his cousin galloped on, he touched his pony with the spur and rode after him. Nearer and nearer they drew towards the rustling grass. Suddenly the movement ceased, and the huge, evil-looking head rose before them. The serpent was undeniably angry, and a big python in a rage is a formidable opponent. "Shoot," whispered Tom in a steady voice. Guy needed not incitement. Already his gun was up; they fired together, and as the double report rattled out, the great serpent, stricken in the head and neck, fell writhing into the pale grass. One of the two shots had luckily broken its backbone a foot or so below the head; but the huge serpent was by no means disabled, and now, half impotent though it was, it struggled furiously to reach its adversaries. Beating and flapping the earth in its agony and rage, it writhed itself towards the two horsemen, who now separated and gave it another shot apiece. Then, recharging their guns, they returned, and finished the wounded monster with a couple more charges. Having ascertained that the snake was really dead, they dismounted and approached it; then, stretching out the reptile to its full length, Tom took a tape measure from his pocket and ran over its dimensions.
