from the tribal caves ten summers before; the stunning shock upon learning that Jotan had taken Dylara with him when he and his party of fellow Ammadians began their journey back to far-off Ammad, mother country of a civilization and culture far in advance of the Cro-Magnon cave dwellers.*

The thrust of a knife from the cowardly and treacherous hand of Sephar's high priest had come near to costing Tharn his life on the eve of his departure in quest of Dylara. As it was, an entire moon passed before the caveman was able to leave his bed.

Pryak, the high priest, had died horribly in payment of his treachery; but Tharn suffered a thousand deaths from enforced idleness while the girl he loved was being carried farther and farther from the one person who possessed the ability to effect her rescue.

And then, over a moon ago, Tharn bade farewell to his mother and to the father whose name he bore, and plunged into the heart of the unfamiliar territory south of Sephar, taking up the trail of those Ammadians who held Dylara.

Near sunset of this particular day, Tharn awoke from a nap, as it was his practice during the baking heat of mid-afternoons. By thus conserving his strength during the more trying portion of the days, he was able to spend many hours after nightfall, when the air was cooler, in pursuit of his quarry.

Rising to his feet on a softly swaying branch a full hundred feet above the jungle floor, Tharn flexed the mighty muscles of arms and legs, his naked chest swelling as he drew in great draughts of humid atmosphere. The slender fingers of his strong, sun-bronzed hand pushed back the shock of thick black hair crowning his finely shaped head and strikingly handsome features, while the flashing, intelligent gray eyes roved quickly over the mazes of foliage surrounding him.

Nor was it his eyes alone that probed those curtains of growing things; ears and a nose keen as those of any jungle dweller were no less active.

He was on the point of descending to the game trail below when Siha, the wind, brought to his sensitive nostrils the scent of man commingled with the acrid smell of Sadu, the lion.

For the space of a dozen heartbeats he stood there, high above the hard-packed earth, while his keen mind rapidly analyzed the message his nose had picked up. From the strength of those scents he knew both man and beast were not far away, while the direction of the breeze told him their position.

Since the day Tharn, the son of Tharn, set out in search of the girl he loved, he had encountered men on several occasions and always those meetings were unpleasant. The Cro-Magnon tribes inhabiting the mountain ranges between Sephar and the land of Ammad were distinguished by their ability as fighters and an unflagging suspicion of strangers. Were it not for Tharn's tremendous strength and incredible agility, he would have died long ere this.

Consequently his first reaction was to let Sadu and the unknown man settle their impending quarrel without his own intervention. But a basic part of Tharn's character was his ready willingness to come to the aid of the underdog, to champion the cause of the weak and oppressed. It was a trait which had brought him to the brink of disaster more than once; but Tharn, were he to have given the matter any thought at all, would not have had it otherwise.

Thus it was that the caveman altered his course to the east and he set off through the trees, swinging among the branches with the ease and celerity of little Nobar, the monkey. Now and then, with the agility of long practice, he sent his lithe body hurtling across some gap between trees, to grasp with unerring accuracy the limb his quick eye had selected. Yet notwithstanding his seemingly reckless pace his passage was almost soundless; and though the tangled verdure appeared as a solid wall, only rarely did his flying figure scrape against the riot of vegetation hemming him in.

A few minutes later the giant Cro-Magnard swung into the branches of a tree at the edge of a large circular clearing. Even as he reached the broad surface of a bough extending over the floor of the open ground, he caught sight of his old enemy, Sadu, the lion, crouching in the trail almost directly beneath him. Simultaneously he saw Sadu's intended prey: a slender Cro-Magnon youth, some four years younger than Tharn himself, who was standing stiffly erect, facing the lion, a flint-tipped spear poised in his right hand.

Tharn felt himself thrill to the boy's unflinching courage even as he recognized its futility, since no human could thus withstand the iron-thewed engine of destruction that was Sadu, the lion.

Tharn was given no opportunity to make use of his arrows or grass rope; for even as he observed the two figures below, the lion's tail shot stiffly erect, a shattering roar split apart the jungle stillness and Sadu charged.

As a swimmer dives from a springboard, so did Tharn launch himself into space, his right hand snatching the flint knife from the folds of his loincloth as he left the branch.

Never before had the cave lord thus attacked the king of beasts; but never before had he sought to wrest Sadu's prey, unharmed, from the animal's fangs and claws. As it was, he landed full upon the lion's back, crushing the beast to earth only inches short of its goal.

Voicing a startled shriek, Sadu rebounded from the forest floor like a tawny ball and turned to rend his foolhardy attacker.

Tharn, however, was not on the ground. His mind, trained from birth to function with lightning-like rapidity, had chosen the only way to prevent his unplanned act from resulting in certain death for himself. And so it was, as his diving body crushed Sadu to the ground, he passed his strong left arm about its neck, locked his powerful legs about its loins, and plunged his flint knife into its side, seeking the savage heart.

Roaring, snarling and spitting in a frenzy of rage, Sadu reared high and toppled back upon the human leech. But Tharn's legs locked only the tighter while the heavy knife, backed by biceps like banded layers of steel, sank home again and again.

Had the battle endured seconds longer the outcome might very well have been reversed. But before then Tharn's weapon tore twice into that untamed heart, and Sadu, with a final fearsome shriek, collapsed to move no more.

As Tharn rose to his feet, his calm gray eyes met the awed, half-mesmerized gaze of the boy whose life he had saved. At sight of the incredulous expression on the young face, the cave lord's firm lips curved in a winning smile that lighted up his strong, noble features.

As for Trakor, he could not have moved or spoken had his life depended on it. There was no doubt in his mind but that he was in the presence of one of the gods old Wokard often described. Who else but a god could slay Sadu with only a knife; who else but a god could possess such a combination of inhuman strength and unbelievable agility? The noble poise of that handsome head above broad shoulders, the soft sinuous curves of that straight and perfect figure, the unclouded bronze skin, the calm dignity of bearing and manner—all those things were attributes of the benign gods who watched over and protected the people of Gerdak's tribe.

Tharn's smile broadened as he guessed something of what was running through the boy's mind.

"Do you," he asked, "hunt often for Sadu with only a spear?"

Trakor shivered. "I would not hunt him with a forest of spears! When he came out of the grasses my blood turned to water and my toes crawled under my heels. Now I know what it is to be afraid!"

"You should have taken to the trees
