Throughout the struggle the tawny beast kept up a continual grunting, choking snarl, while the man fought in utter silence. At last the whole length of the professor's left arm had been dragged through, until only his hand itself was in the mouth of the puma. Shoving it down her hot gullet, he gripped the base of her tongue so chokingly that the struggling panther was unable to close her jaws, and, for the first time during the fight, the professor was free from the pain of her piercing teeth.

In a desperate struggle to release the grip which was shutting off her breath, the puma lurched over and fell full length on her back in the loose sand, dragging the man down with her, and the professor found himself with his left hand deep in her gullet, his right hand still clutching the beast's throat desperately, while his knees, with the weight of his body back of them, pressed full against her ribs on each side. As they struck the ground he sank his elbows into the armpits of the puma beneath him, spreading her front legs and pinning them down, so that her frantic claws could reach inward only enough to rip his coat, without wounding the flesh beneath. Once on the ground, the panther struggled fiercely, pitching and bucking in an effort to release herself from the man's weight so that she could be in a position to make use of the curved scimitars with which all four of her paws were armed. The loose sand shifted and gave her no purchase.

As they fought, Professor Ditson felt his strength leaving him with the blood that flowed from his gashed and mangled arm. Raising himself a little, he surged down with both knees and felt a rib snap under his weight and the struggling body relax a trifle. For the first time he dared hope to do what no man had done since the cavemen contended with their foes among the beast-folk, and to his surprise noted that he was beginning to take a certain grim pleasure in the combat. The fury of the fight had pierced through the veneer of education and culture, and Professor Amandus Ditson, the holder of degrees from half a dozen learned universities, battled for his life that day with a beast of the forest with all the desperation and fierce joy which any of his prehistoric forebears might have felt a hundred thousand years ago.

It had become a question as to which would give up first—the man or the beast. Fighting off the waves of blackness which seemed to surge up and up until they threatened to close over his head, he fought desperately with clutching hands and driving knees, under which the thin ribs of the puma snapped like dry branches, until at last, with a long, convulsive shudder, the great cat stopped breathing. Even as he felt the tense body relax and become motionless under his grip, the blackness closed over his head.

There the rest of the party, alarmed by his long absence, found him an hour later. His gaunt body was stretched out on the dead panther and his right hand was sunk in the long fur, while his left hand and arm were buried to the elbow in the fierce gaping mouth and his bowed knees still pinned the great cat down. Around the dead beast and the unconscious man sat four black vultures. Thrusting forward from time to time their naked, red, hooded heads, they seemed about to begin their feast when the rescuing party arrived. With his face hidden in the panther's tawny fur, Professor Ditson seemed as dead as the beast that lay beneath him. It was not until Hen had pried his fingers away from the puma's throat and carefully drawn his gashed hand from the beast's gullet that his eyes flickered open and his gaunt chest strained with a long, labored breath.

"I was wrong," were his first words. "The Felis concolor does occasionally attack man. I'll make a note of it," he went on weakly, "in the next edition of my zoölogy."

"I was wrong, too," burst out Jud, pressing close up to the exhausted scientist and clasping his uninjured hand in both of his. "I thought you were nothin' but a perfesser, but I want to say right here an' now that you're a man."

The danger, however, was not yet over. The scratches and bites of a panther or a jaguar, like those of a lion or tiger, almost invariably cause death from blood-poisoning if not immediately treated. Under Professor Ditson's half-whispered directions, they stripped off his clothes, washed away the blood and dirt with clear water, and then, using the little surgical kit which he always wore at his belt, injected a solution of iodine into every scratch and tooth-mark.

"It is necessary," said the scientist, gritting his teeth as the stinging liquid smarted and burned like fire, "but I do not believe that life itself is worth so much suffering."

The rest of the party, however, did not agree with this perhaps hasty opinion, and persisted in their treatment until every puncture was properly sterilized. Then, bandaged with great handfuls of cool sphagnum moss and attended by the faithful Hen Pine, the professor slept the clock around. While he was asleep, Will and Pinto slipped away together to see if they could not bring back a plump curassow from which to make broth for him when he finally woke up; while Jud and Joe, with similar good intentions, scoured the jungle for the best-flavored fruits they might find.
