I suggest that we remain here until we are all thoroughly rested and then take up a systematic search for the city of Korsar."

The plan met with general approval and preparations were made for a stay of several days.

"I believe," said Gridley to Captain Zuppner, "that it would be well to issue strict orders that no one is to leave the ship, or rather its close vicinity, without permission from you and that no one be allowed to venture far afield except in parties commanded by an officer, for we have every assurance that we shall meet with savage men and far more savage beasts everywhere within Pellucidar."

"I hope that you will except me from that order," said Tarzan, smiling.

"I believe that you can take care of yourself in any country," said Zuppner.

"And I can certainly hunt to better effect alone than I can with a party," said the ape-man.

"In any event," continued Zuppner, "the order comes from you as commander, and no one will complain if you exempt yourself from its provisions since I am sure that none of the rest of us is particularly anxious to wander about Pellucidar alone."

Officers and men, with the exception of the watch, which changed every four hours, slept the clock around.

Tarzan of the Apes was the first to complete his sleep and leave the ship. He had discarded the clothing that had encumbered and annoyed him since he had left his own African jungle to join in the preparation of the O-220, and it was no faultlessly attired Englishman that came from the cabin and dropped to the ground below, but instead an almost naked and primitive warrior, armed with hunting knife, spear, a bow and arrows, and the long rope which Tarzan always carried, for in the hunt he preferred the weapons of his youth to the firearms of civilization.

Lieutenant Dorf, the only officer on duty at the time, saw him depart and watched with unfeigned admiration as the black-haired jungle lord moved across the open plain and disappeared in the forest.

There were trees that were familiar to the eyes of the ape-man and trees such as he had never seen before, but it was a forest and that was enough to lure Tarzan of the Apes and permit him to forget the last few weeks that had been spent amidst the distasteful surroundings of civilization. He was happy to be free from the ship, too, and, while he liked all his companions, he was yet glad to be alone.

In the first flight of his new-found freedom Tarzan was like a boy released from school. Unhampered by the hated vestments of civilization, out of sight of anything that might even remotely remind him of the atrocities with which man scars the face of nature, he filled his lungs with the free air of Pellucidar, leaped into a nearby tree and swung away through the forest, his only concern for the moment the joyousness of exultant vitality and life. On he sped through the primeval forest of Pellucidar. Strange birds, startled by his swift and silent passage, flew screaming from his path, and strange beasts slunk to cover beneath him. But Tarzan did not care; he was not hunting; he was not even searching for the new in this new world. For the moment he was only living.

While this mood dominated him Tarzan gave no thought to the passage of time any more than he had given thought to the timelessness of Pellucidar, whose noonday sun, hanging perpetually at zenith, gives a lie to us of the outer crust who rush frantically through life in mad and futile effort to beat the earth in her revolutions.

Nor did Tarzan reckon upon distance or direction, for such matters were seldom the subjects of conscious consideration upon the part of the ape-man, whose remarkable ability to meet every and any emergency he unconsciously attributed to powers that lay within himself, not stopping to consider that in his own jungle he relied upon the friendly sun and moon and stars as guides by day and night, and to the myriad familiar things that spoke to him in a friendly, voiceless language that only the jungle people can interpret.

As his mood changed Tarzan reduced his speed, and presently he dropped to the ground in a well-marked game trail. Now he let his eyes take in the new wonders all about him. He noticed the evidences of great age as betokened by the enormous size of the trees and the hoary stems of the great vines that clung to many of them—suggestions of age that made his own jungle seem modern—and he marvelled at the gorgeous flowers that bloomed in riotous profusion upon every hand, and then of a sudden something gripped him about the body and snapped him high into the air.

Tarzan of the Apes had nodded. His mind occupied with the wonders of this new world had permitted a momentary relaxation of that habitual wariness that distinguishes creatures of the wild.

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.

But even as he permitted these thoughts partially to reassure him, there came strongly to his nostrils a scent that always caused the short hairs upon his head to rise, not in fear but in natural reaction to the presence of an hereditary enemy. It was not an odor that he had ever smelled before. It was not the scent spoor of Numa the lion, nor Sheeta the leopard, but it was the scent spoor of some sort of great cat. And now he could hear its almost silent approach through the underbrush and he knew that it was coming down toward the trail, lured either by knowledge of his presence or by that of the beast whose approach Tarzan had been awaiting.

It was the latter who came first into view—a great ox-like animal with wide-spread horns and shaggy coat—a huge bull that advanced several yards along the trail after Tarzan discovered it before it saw the ape-man dangling in front of it. It was the thag of Pellucidar, the Bos Primigenus of the paleontologist of the outer crust, a long extinct progenitor of the bovine races of our own world.

For a moment it stood eyeing the man dangling in its path.

Tarzan remained very quiet. He did not wish to frighten it away for he realized that one of them must be the prey of the carnivore sneaking upon them, but if he expected the thag to be frightened he soon realized his error in judgment for, uttering low grumblings, the great bull pawed the earth with a front foot, and then, lowering his massive horns, gored it angrily, and the ape-man knew that he was working his short temper up to charging pitch; nor did it seem that this was to take long for already he was advancing menacingly to the accompaniment of thunderous bellowing. His tail was up and his head down as he broke into the trot that preluded the charge.

The ape-man realized that if he was ever struck by those massive horns or that heavy head, his skull would be crushed like an eggshell.

The dizzy spinning that had been caused by the first stretching of the rawhide to his weight had lessened to a gentle turning motion, so that sometimes he faced the thag and sometimes in the opposite direction. The utter helplessness of his position galled the ape-man and gave him more concern than any consideration of impending death. From childhood he had walked hand in hand with the Grim Reaper and he had looked upon death in so many forms that it held no terror for him. He knew that it was the final experience of all created things, that it must as inevitably come to him as to others and while he loved life and did not wish to die, its mere approach induced within him no futile hysteria. But to die without a chance to fight for life was not such an end as Tarzan of the Apes would have chosen. And now, as his body slowly revolved and his eyes were turned away from the charging thag, his heart sank at the thought that he was not even to be vouchsafed the meager satisfaction of meeting death face to face.

In the brief instant that he waited for the impact, the air was rent by as horrid a scream as had ever broken upon the ears of the ape-man and the bellowing of the bull rose suddenly to a higher pitch and mingled with that other awesome sound.

Once more the dangling body of the ape-man revolved and his eyes fell upon such a scene as had not been vouchsafed to men of the outer world for countless ages. Upon the massive shoulders and neck of the great thag clung a tiger of such huge proportions that Tarzan could scarce credit the testimony of his own eyes.
