Instead, he filled his lungs with air before the huge reptile dragged him beneath the surface, and then, with all the might of his great muscles, fought bitterly for freedom. But out of his native element the ape-man was too greatly handicapped to do more than excite the monster to greater speed as it dragged its prey swiftly through the water.

Tarzan’s lungs were bursting for a breath of pure fresh air. He knew that he could survive but a moment more, and in the last paroxysm of his suffering he did what he could to avenge his own death.

His body trailed out beside the slimy carcass of his captor, and into the tough armour the ape-man attempted to plunge his stone knife as he was borne to the creature’s horrid den.

His efforts but served to accelerate the speed of the crocodile, and just as the ape-man realized that he had reached the limit of his endurance he felt his body dragged to a muddy bed and his nostrils rise above the water’s surface. All about him was the blackness of the pit—the silence of the grave.

For a moment Tarzan of the Apes lay gasping for breath upon the slimy, evil-smelling bed to which the animal had borne him. Close at his side he could feel the cold, hard plates of the creature’s coat rising and falling as though with spasmodic efforts to breathe.

For several minutes the two lay thus, and then a sudden convulsion of the giant carcass at the man’s side, a tremor, and a stiffening brought Tarzan to his knees beside the crocodile. To his utter amazement he found that the beast was dead. The slim knife had found a vulnerable spot in the scaly armour.

Staggering to his feet, the ape-man groped about the reeking, oozy den. He found that he was imprisoned in a subterranean chamber amply large enough to have accommodated a dozen or more of the huge animals such as the one that had dragged him thither.

He realized that he was in the creature’s hidden nest far under the bank of the stream, and that doubtless the only means of ingress or egress lay through the submerged opening through which the crocodile had brought him.

His first thought, of course, was of escape, but that he could make his way to the surface of the river beyond and then to the shore seemed highly improbable. There might be turns and windings in the neck of the passage, or, most to be feared, he might meet another of the slimy inhabitants of the retreat upon his journey outward.

Even should he reach the river in safety, there was still the danger of his being again attacked before he could effect a safe landing. Still there was no alternative, and, filling his lungs with the close and reeking air of the chamber, Tarzan of the Apes dived into the dark and watery hole which he could not see but had felt out and found with his feet and legs.
