Jim could see clearly now, for the light from the Eye was slowly diminishing in brilliancy, or else his own eyes were growing more accustomed to it. Those carven figures, forming a semi-circle upon the platform were figures of G.o.ds, squat, huge forms seeming to emerge out of the blocks of rock from which they had been fashioned.

Hideous, gruesome carvings they were, resembling some futuristic sculpture of to-day, for the artist who had fashioned them had given hardly more than a hint of the finished representation. It was rather as if the ma.s.ses of rock that had been transported there had become vitalized, foreshadowing the dim yet awful beings that were some day to emerge from them.

Only the arms were clearly sculptured, and each of the half-dozen figures squatting upon its haunches in that semi-circle had four of them. Arms that protruded so as to form an interlacing network, and the fingers were long claws fashioned of some metal. Over the arms the shapeless heads beat down with a leering look, and from each mouth protruded a curved tongue.

A masterpiece of horror, that group, like the great stone figures of the Aztecs, or some of the hideous Indian G.o.ds. Seen under the glare of the Eye, they formed a background of horrible omen. In a flash it dawned upon Jim that these hideous figures might be G.o.ds of b.l.o.o.d.y sacrifice.

"That's why these people seem so gentle," he heard himself saying.

"It's the--the contrast."

He pulled himself together. Again he tried to move towards Lucille, and again that invisible force restrained him.

Yes, it was the captured Atom Smasher upon the platform, and those forms grouped in front of the dignitaries were captured Drilgoes, a dozen or so of them. And the concealed priest was droning a chant again. Every other sound was hushed, but from each square foot of the great amphitheatre a pair of eyes was watching.

A myriad of eyes turned upon the platform! What was going to happen next?

Suddenly the priest's voice died away, and simultaneously the three dignitaries, who seemed to be officiating priests, from their solemn gestures, stepped backward, pa.s.sing beneath the protruding arms of the idols. There sounded the deep whir of some mechanism somewhere, and the same invisible force that had Jim and his two companions in its control suddenly began to agitate the captive Drilgoes.

_It was shuffling them!_ It was forcing them into line, pushing here and pulling there, in spite of the Drilgoes' terrified struggles. They writhed and twisted, groaning and clicking in abject terror as they wrestled with that unseen power, and all in vain. Slowly the foremost of the Drilgoes was propelled forward, inch by inch, until he stood immediately beneath the interlacing arms.

And what happened next filled Jim with sick horror and loathing. For of a sudden the arms began to move, the iron claws cut through the air--a shriek of terror and anguish broke from the Drilgo's mouth ...

and he was no longer a man, but a clawed and pulped ma.s.s of human flesh!

"Aiah! Aiah! Aiah!" broke from the throats of the a.s.sembled mult.i.tude.

The weaving arms had stopped. From behind them an attendant was gathering up what had been the Drilgo in a basket. Then the mechanism had begun again, and again that shrill cry of the spectators was ringing in Jim's ears.

Louder still rose the shriek of old Parrish as he understood. Jim put forth all his strength in a mad effort to break free. A child would have had more chance in the grip of a giant. And each time the arms of the G.o.ds revolved, the unseen force pushed Jim, Lucille, and Parrish nearer the platform.

Now Jim understood. This horrible sacrifice was a part of the religion of the Atlanteans, and he, Lucille, and Parrish, were being reserved for the final spectacle.

And at the sight of Lucille beside him, stonily unconscious, and yet standing, and moving like a mechanical doll, in little forward jerks--at the sight of the girl, hardly six feet distant, and yet utterly beyond the touch of his finger-tips, Jim went mad. He would not shout; he closed his lips in pride of race, pride of that civilization that he had left twelve thousand years ahead of him. Not like the shrieking Drilgoes on the platform, howling as each of them in turn was forced into that maze of revolving knives. But he fought as a madman fights. He hammered at the resilient air, while the sweat ran down his face, he braced his feet upon the wooden tongue, and sought to stay his forward progress. And all the while that infernal force moved him steadily onward.

He was on the platform now. He was traveling the same route that the Drilgoes had taken. The unseen force was shuffling him, Lucille, and Parrish, pushing and pulling them. And, despite Jim's efforts, it was Lucille who was first of the three ... and Jim second ... and old Parrish third....

Jim heard Parrish's hoa.r.s.e whisper behind him, "Death! Death! The uranium!" He was fumbling at his breast, but the significance of the words and gestures escaped him. He was staring ahead. Only three living Drilgoes of the whole number of prisoners remained alive, and suddenly it was borne in upon Jim that he knew the last of the three.

It was the Drilgo, Cain, who had been their companion in the Atom Smasher--there, not a dozen feet distant. Cain, his b.e.s.t.i.a.l face, with the ridged eyebrows and great jaws convulsed with terror and dripping sweat. Cain, immediately in front of Lucille.

"G.o.d, let her not wake! Let her never know!" Jim breathed. The agony would be but momentary. And there was nothing a man could not endure if he must. He could even endure to see Lucille become--what the Drilgoes had become. It would soon be over now.

The Eye was blinking overhead. The hideous stone faces of the Atlantean G.o.ds looked down in leering mockery. Another of the Drilgoes had gone the same route as the others. Cain was the second now, Lucille the third victim, and he, Jim, would be the fourth.

Gritting his teeth, Jim saw the next Drilgo propelled forward into the whirling knives. He saw the man fling up his arms, as if to shield his head--and then he was a man no longer, and the horrible knives revolved, and "Aiah! Aiah! Aiah!" cried the mult.i.tude.

Once more the mechanism whirred.... Once more the arms revolved. A howl of terror broke from Cain's lips as he was propelled onward....

Then suddenly the whirring stopped. The arms of the stone G.o.ds, with their hooked, razorlike claws, to which clung particles of flesh, were arrested in mid-air. Cain, unharmed, was leaning backward, his features set in a mask of awful fear.

Simultaneously Jim knew that the force which had held him in thrall was gone. He flung his arms out. He was free. He grasped Lucille, held her tightly against his breast, stood there drawing great, labored breaths, waiting--for what?

A film was creeping over his eyes, but he was aware that the Eye had suddenly gone out. And out of the dark the priest was chanting.

Then came a deep-drawn sigh from the spectators, followed by a ringing shout. In place of the Eye the full moon appeared, sailing overhead.

And, holding off that deathly weakness, Jim understood. The sacrifice had ended; a new month had begun....

CHAPTER VII

_Back to Long Island_

Jim, seated beside Lucille, was listening to Cain's gruntings and chucklings as he expounded the situation to old Parrish.

It was the day following the scene in the amphitheatre. The four had been escorted back along the tongue of flooring into a hall with walls of fretted stone and sumptuous colorings. The floor was strewn with rich rugs woven of some vegetable fibre. There were divans and low chairs. At brief intervals, servitors, always smiling, pa.s.sed carrying trays with wines and foods. And in the corridors were always glimpses of the guards.

"It was the rising of the full moon saved our lives, Dent," Parrish explained. "It appears they have this sacrifice at each of the moon's phases. The victims, captives or criminals, are eaten by the priests.

We've got a week's respite, Dent, and then--G.o.d help us."

Jim's arm tightened about Lucille, but the girl turned and smiled into his face. There was no longer any fear there. And Jim swore to himself that he would yet find some way of outwitting their devilish captors.

"What the devil are we supposed to be, criminals or what?" he asked her father. "Why do they smile at us all the time in that confounded way?"

Parrish questioned the Drilgo, but apparently he was unable to explain himself to him. "Maybe they think it an honor for us, Dent," he answered, "or maybe it's their idea of etiquette. Anyway, we four are to head the list when the moon's at the three-quarters. G.o.d, if only we could reach the Atom Smasher, I'm certain I could find out how it works!"

Jim had tried more than once to reach it. Through the colonnades at the end of the hall he could see the mechanism standing on the platform, always being inspected by half a dozen or so of the dignitaries of Atlantis. But all his attempts to cross that tongue of flooring had been vetoed by the guards.

They had presented their hands to him, palms outward, and on the palms were fine steel points, about two inches long, set into leather gauntlets. It had been impossible to try conclusions with them.

Two days went by. Once a group of dignitaries had entered the hall and, with smiles and profuse bows, inspected the prisoners. Then they had departed. And Jim had paced the floor, to and fro, thinking desperately.

There was no sort of weapon with which to hazard an attack. Jim knew that they were under the closest observation. He could only wait and hope. And if all else failed, he meant to hurl himself, with Lucille in his arms, off the tongue of floor into the depths below when their time came.

On the third morning, after a troubled sleep induced by very weariness, Jim was awakened by one of the guards, and started up to see one of the bowing dignitaries before him, and Parrish and Lucille sitting up among their rugs.

Bowing repeatedly, the smiling old man addressed some words to Jim, and then turned to Parrish.

"He says he wants you to show him the way the Atom Smasher works,"

said Parrish. "Now's our chance, Dent. He thinks it's simply an apparatus for neutralizing the blue-white ray. Don't let him guess--"
