Before he had time to retreat, the bushes parted and out from them leaped a jaguar. Its spotted back reared high in the air and, with an infuriated squall, it came down at Hal’s feet. An arrow sticking out of its thick neck told the story.

Obviously the animal was as much surprised as Hal, for it backed down a moment, crouching on its hind legs and swinging its tail with a great thumping sound each time it switched on the ground. But not for a moment did it take its savage eyes from the astonished young man before it.

Hal saw at once that the animal was suffering great pain from the arrow, but the wound was not mortal. Its frequent squalls betokened anger and revenge against all humanity, and, from the hard glint in its eyes, this retaliation would be thorough.

Hal did not stir from the spot, but, with a stealthy gesture, he reached around to his back pocket. The next second he had aimed the gun at a spot right between the jaguar’s steely eyes, but his aim was poor with his left hand and he knew it. Consequently, the second the explosion occurred, he was fleeing toward the nearest tree.

Up the slimy trunk he clambered, but not before the animal reached out and clawed his right leg. Nevertheless, he hitched himself up, biting his lips with pain, and settled on the nearest bough. Meanwhile, the jaguar was crawling after him, hissing and emitting blood-curdling cries.

Hal aimed the gun again, this time supporting it as best he could with his swollen right hand. The bullet sang, the jaguar screamed, and before its echo had died away in the tree tops, it fell with a terrific thud and rolled five or six feet before its spotted body became rigid in death.

For a long time, Hal stayed where he was, fearing that the cat might suddenly revive. But when ten minutes had passed and there was no sign of such a miracle, he carefully replaced the gun in his pocket and undertook to get down from his uncomfortable retreat.

He soon found that he could not use his leg at all and had to slide to the ground, blistering his good hand and feeling faint when he tried to stand upright. He reached out to support himself on the tree trunk but a wave of giddiness passed through his throbbing head and though he felt himself sinking he seemed not to be able to prevent it.

He found himself in a heap and seemed to have neither the strength nor the desire to do aught but stretch out and lie where he was. Pain governed him now from head to foot and he feared for his wounded leg. But the fear soon gave way to a sort of apathy out of which he did not rise.

His eyes noted indifferently the sun climbing higher in the blue heavens. It gleamed quite strongly through the swaying branches and, in its glistening light, various-colored birds flitted about. Suddenly he saw something black moving with a familiar whirling motion.
