Kamrou flung off his long and heavy cloak. He stood there in the flamelight, broad-chested, beautifully muscled, lean of hip, the perfect picture of a fighting man. Naked he was, save for his loin-cloth. And still he smiled.

Stern likewise stripped away his own cloak. Clad only like the chief, he faced him.

"Well, now," said he, "here goes! And may the best man win!"

Kamrou waved the circle back at one side. It opened, revealing the great pit to southward of the flame. Stern saw the vapors rising, bluish in that strange light, from the perpetual boiling of the black waters in its depths. Oddly enough, even at that moment a stray bit of scientific thought nicked into his consciousness--the memory that under compressed air water boils only at very high temperatures. Down here, in this great pressure, the water must easily be over three hundred degrees to seethe like that.

He, too, smiled.

"So much the better," thought he. "The hotter, the sooner it's all over for the man who goes!"

Up rose numbers of the two-p.r.o.nged torches. Stern got confused glimpses of the Folk--he saw the terrible, barbaric eagerness with which they now antic.i.p.ated this inevitable tragedy of at least one human death in its most awful form.

Beatrice he no longer saw. Where was she? He knew not. But in a long, last cry of farewell he raised his voice. Then, with Kamrou, he strode toward the steaming, boiling pit in the smooth rock floor.

Two tall men broke through the tensely eager throng. In their hands they bore each a golden jar, curiously shaped and chiseled, and bearing a whimsical resemblance to a coffee-urn.

"What the devil now?" wondered Stern, eager to be at work. He saw at once the meaning of the jars. One of the bearers approached Kamrou.

The other came to him. They raised the vessels, and over the antagonists' bare bodies poured a thin, warm stream of some rank-smelling oil. All over the skin they rubbed it, till the bodies glistened strangely in the flamelight. Then, with muttered words he could not catch, they withdrew.

All seemed confused and vague to Stern as in a painful dream. Images and pictures seemed to present themselves to his brain. The light, the fog and heat, the rising stream, the roaring of the flame, and over all the throb-throb-throb of those infernal copper drums worked powerfully on his senses.

Already he seemed to feel the grip of Kamrou, the pangs of the hard struggle, the sudden plunge into the vat of scalding death.

With a strong effort he flung off these fancies and faced his sneering foe, who now--his red-wealed face puckered into a malicious grin--stood waiting.

Stern all at once saw the patriarch once more.

"Go, son!" cried the old man. "Now is the moment! When the drums cease, lay hold of him!"

Even as he spoke, the great drums slowed their beat, then stopped.

Stern, with a final thought of Beatrice, advanced.

All the advantage lay with Kamrou. Familiar with the place was he, and with the rules of this incredible contest. Everywhere about him stood crowding hundreds of his Foll; owing him their allegiance, hostile to the newcomer, the man from another world. Out of all that mult.i.tude only two hearts' beat in sympathy and hope for him; only two human beings gave him their thoughts and their support--a helpless girl; a feeble, blind old man.

Kamrou stood taller, too, than Stern, and certainly bulked heavier. He was in perfect condition, while Stern had not yet fully recovered from the fight in the Abyss, from the great change in living conditions there in the depths, and--more important still--from the harsh blow of the rock that had numbed his elbow on the beach.

His arms and hands, too, still felt the cramping of the cords that had bound him. He needed a few hours yet to work them into suppleness and perfect strength. But respite there was none.

He must fight now at once under all handicaps, or die--and in his death yield Beatrice to the barbaric pa.s.sions of the chief.

Oddly enough there recurred to his mind, as he drew near the waiting, sneering Kamrou, that brave old war-cry of the Greeks of Xenophon as they hurled themselves against the vastly greater army of the Persians--"Zeus Sotor kai Nike!--Zeus Savior and victory!"

The shout burst from his lips. Forward he ran, on to the battle where either he or the barbarian must perish in the boiling pit--forward, _to what? To victory--to death?_

Kamrou stood fast till Stern's right hand had almost gripped his throat--for Stern, the challenger, had to deliver the first attack.

But suddenly he slipped aside; and as Stern swerved for him, made a quick leap.

With an agility, a strength and skill tiger-like and marvelous, he caught Stern round the waist, whirled him and would have dashed him toward the pit. But already the engineer's right arm was under Kamrou's left; the right hand had him by the throat, and Kamrou's head went sharply back till the vertebrae strained hard.

Eel-like, elusive, oiled, the chief broke the hold, even as he flung a leg about one of Stern's.

A moment they swayed, tugging, straining, panting. In the old days Stern would not for one moment have been a match for this barbaric athlete, but the long months of life close to nature had hardened him and toughened every fiber. And now a stab of joy thrilled through him as he realized that in his muscles lay at least a force to balk the savage for a little while.

To Stern came back his wrestling lore of the very long ago, the days of Harvard, in the dim, vanished past. He freed his left arm from the gorilla-like grip of Kamrou, and, quick as lightning, got a jiu-jitsu stranglehold.

The savage choked, gurgled, writhed; his face grew purple with stagnant blood. Then he leaped, dragging the engineer with him; they fell, rolled, twisted--and Stern's hold was broken.

A great shout rose as Kamrou struggled up and once more seized the American. He raised him like a child, and took a step, two, three, toward the infernal caldron in the rock floor.

Stern, desperate, wrenched his oiled arms clear. A second later they had closed again about the chief's throat--the one point of attack that Stern had chosen for his best.

The barbarian faltered. Grunting, panting, he shook the engineer as a dog shakes a rat, but the hold was secure. Kamrou's great arms wrapped themselves in a formidable "body-scissors" grip; Stern felt the breath squeezed from his body.

Then suddenly the chief's oily heel slipped on the smooth-worn rock, not ten feet from the lip of the bubbling vat--and for the second time both fell.

This time Stern was atop. Over they rolled, once, twice, straining with madness. Stern's thumbs were sunk deep in the throat of the barbarian at either side. As he gouged harder, deeper, he felt the terrific pounding of the chief's jugular. Hot on his own neck panted the choking breath of Kamrou. Oh, could he only hold that grip a minute longer--even a half-minute!

But already his own breath was gone. A buzzing filled his ears; sparkling lights danced, quivering before his eyes. The blood seemed bursting his brain; far off and vague he heard the droning of the flame, the shouts and cries of the great horde of watchers.

A whiff of steam--hot, damp, terrifying--pa.s.sed across his face, in which the veins were starting from the oily skin. His eyes, half closed, bulged from the sockets. He knew the pit was very close now; dully he heard its steady bubbling.

"If I go--he goes, too!" the engineer swore to himself. "He'll never have--Beatrice--anyway!"

Over and over they rolled, their grips tight-locked as steel. Now Kamrou was on top, now Stern. But the chief's muscles were still strong as ever; Stern's already had begun to weaken.

Strive as he might, he could not get another hold, nor could he throw another ounce of power into that he already had. Up, up, slowly up slipped the chief's arms; Stern knew the savage meant to throttle him; and once those long, prehensile fingers reached his throat, good-by!

Then it seemed to him a voice, very far and small, was speaking to him, coolly, impersonally, in a matter-of-fact way as though suggesting an experiment.

Dazed as he was, he recognized that voice--it was the voice of Dr.

Harb.u.t.t, who once had taught him many a wily trick upon the mat; Harb.u.t.t, dead and gone these thousand years or more.

"Why not try the satsu-da, Stern?" the voice was saying. "Excellent, at times."

Though Stern's face was black and swollen, eyes shut and mouth all twisted awry in this t.i.tanic struggle with the ape-hold of the huge chief, yet the soul within him calmly smiled.

The satsu-da--yes, he remembered it now, strongest and best of all the jiu-jitsu feats.

And, suddenly loosening his hands from the chief's throat, he clenched his right fist, hard as steel.

A second later the "killing-blow" had fallen on the barbarian's neck, just where the swelling protuberance behind the ear marked the vital spot.

Terrible was the force of that blow, struck for his own life, for the honor of Beatrice, the salvation of the world.
