Almost in the instant of its occurrence the ape-man realized what had befallen him. Although he could easily imagine its disastrous sequel, the suggestion of a smile touched his lips--a rueful smile--and one that was perhaps tinged with disgust for himself, for Tarzan of the Apes had been caught in as primitive a snare as was ever laid for unwary beasts. A rawhide noose, attached to the downbent limb of an overhanging tree, had been buried in the trail along which he had been passing and he had struck the trigger--that was the whole story. But its sequel might have had less unfortunate possibilities had the noose not pinioned his arms to his sides as it closed about him. He hung about six feet above the trail, caught securely about the hips, the noose imprisoning his arms between elbows and wrists and pinioning them securely to his sides. And to add to his discomfort and helplessness, he swung head downward, spinning dizzily like a human plumb-bob. He tried to draw an arm from the encircling noose so that he might reach his hunting knife and free himself, but the weight of his body constantly drew the noose more tightly about him and every effort upon his part seemed but to strengthen the relentless grip of the rawhide that was pressing deep into his flesh. He knew that the snare meant the presence of men and that doubtless they would soon come to inspect their noose, for his own knowledge of primitive hunting taught him that they would not leave their snares long untended, since in the event of a catch, if they would have it at all, they must claim it soon lest it fall prey to carnivorous beasts or birds. He wondered what sort of people they were and if he might not make friends with them, but whatever they were he hoped that they would come before the beasts of prey came. And while such thoughts were running through his mind, his keen ears caught the sound of approaching footsteps, but they were not the steps of men. Whatever was approaching was approaching across the wind and he could detect no scent spoor; nor, upon the other hand, he realized, could the beast scent him. It was coming leisurely and as it neared him, but before it came in sight along the trail, he knew that it was a hoofed animal and, therefore, that he had little reason to fear its approach unless, indeed, it might prove to be some strange Pellucidarian creature with characteristics entirely unlike any that he knew upon the outer crust.
