Astounding Stories, April, 1931

"Randall!" It was Lanier's thick exclamation. "Randall – those scar-marks on their – faces – you see – ?"

"See?"

"Those marks! These creatures had eyes once but must have been forced down here by the Martians. These may once have been – ages ago – human!"

At that thought Randall felt horror overcoming his senses. He was aware that the great worm monster holding them was dragging them forward through the cavern, that others of the swarms there were crowding around them, feeling them blindly with their tentacles, helping to drag them forward.

Half-carried and half-dragged they went, scores of tentacles now holding them, great worm shapes crawling forward on all sides of them and accompanying them along the cavern's length. He glimpsed worm monsters here and there emerging from the upward tunnels with masses of strange plant stuff in their grasp that others blindly devoured. His senses reeled from the suffocating air, the great cavity being but a half-score feet in height, burrowed from the damp earth by these numberless things.

The faint, strange light of the radio-active patches showed him that they were approaching the cavern's end. Tunnels opened from its end as from all its walls and floor, and into one Randall was dragged by the creatures, one before and one behind, grasping him, and Lanier being brought behind him in the same way. In the close tunnel the heavy air was deadly, and he was but partly conscious when again, after moments of crawling along it, he felt himself dragged out into another cavern.

This earth-walled cavity, though, seemed to extend farther than the first, though of the same height as the first and with a few radio-active illuminating patches. In it seethed and swarmed literally hundreds on hundreds of the worm monsters, a sea of great crawling bodies. Randall and Lanier saw that they were being carried and dragged now toward the farther end of this larger cavity.

As they approached it, pushing through the swarming creatures who felt them with inquisitive tentacles as their captors took them forward, the two men saw that a great shape was looming up in the faint light at the cave's far end. In moments they were close enough to discern its nature, and a horror and awe filled them at sight of it more intense than they had yet felt.

For the looming shape was a huge earthen image or statue of a worm! It was shaped with a childish crudeness from the solid earth, a giant earthen worm shape whose body looped across the cave's end, and whose tentacled head or front end was reared upward to the cavity's roof. Before this awful earthen shape was a section of the cave's floor higher than the rest, and on it a great crudely shaped rectangular earthen block.

"Lanier – that shape!" whispered Randall in his horror. "That earthen image, made by these creatures – it's the worm god they've made for themselves!"

"A worm god!" Lanier repeated, staring toward it as they were dragged nearer. "Then that block…"

"Its altar!" Randall exclaimed. "These things have some dim spark of intelligence or memory! They're brought us here to – "

Before he could finish, the clutching tentacles of the worm monsters about them had dragged them up onto the raised floor beside the block, beneath the looming earthen worm shape. There they glimpsed for the first time in the faint light another who stood there held tightly by the tentacles of two worm monsters. It was a Martian!

The big crocodilian shape was apparently a prisoner like themselves, captured and brought down from above. His reptilian eyes surveyed Lanier and Randall quickly as they were dragged up and held beside him, but he took no other interest. To the two men, at the moment, it seemed that his great crocodilian shape was human, almost, so much more man-like was it than the grotesque worm monsters before them.

With a half-dozen of the creatures holding the two men and the Martian tightly, another great worm monster crawled to the edge of the raised earth floor in front of the giant worm god's image, and then reared up the first third of his thick body into the air. By then the great, faint-lit cavity stretching before them was filled with countless numbers of the monsters, pouring into it from all the tunnels that opened into it from above and below, packing it thick with their grotesque bodies as far as the eye could reach in the dim light.

They were seething and crawling in that great mass; but as the worm monster on the elevation upreared, all in the cavity seemed suddenly to quiet. Then the upreared eyeless thing began to move his long tentacles. Very slowly at first he waved them back and forth, and slowly the masses of monsters in the cavity, all turned by some sense toward him, did likewise, the cavity becoming a forest of upraised tentacles waving rhythmically back and forth in unison with those of the leader.

Back and forth – back and forth – Randall felt caught in some torturing nightmare as he watched the countless tentacle-feelers waving thus from one side to the other. It was a ceremony, he knew – some strange rite springing perhaps from dim memory alone, that these worm monsters carried out thus before the looming shape of their worm god. Only the six that held the three captives never relaxed their grip.

Still on and on went the strange and senseless rite. By then the close, damp air of that cavity far beneath Mars' surface was sinking Randall and Lanier deeper into a half-consciousness. The Martian beside them never moved or spoke. The upstretched tentacles of the leader and of the great worm horde before him never ceased swaying rhythmically from side to side.

Randall, half-hypnotized by those swaying tentacles and but semi-conscious by then, could only estimate afterward how long that grotesque rite went on. Hours it must have endured, he knew, hours in which each opening of his eyes revealed only the dimly-illuminated cavern, the worm monsters that filled it, the forest of tentacles waving in unison. It was only toward the end of those hours that he noticed vaguely that the tentacles were waving faster and faster.

And as the tentacles of leader and worm horde waved alike ever more swiftly an atmosphere of growing excitement and expectation seemed to hold the horde. At last the upstretched feelers were whipping back and forth almost too swiftly for the eye to follow. Then abruptly the worm leader ceased the motion himself, and while the horde before him continued it, turned and crawled to the three captives.

In an instant, as though in answer to a second command, the two worm monsters who held the Martian dragged him forward toward the great earthen block before the worm god's image. Two others of the creatures came from the side, and the four swiftly stretched the Martian flat on the block's top, each of the four grasping with their tentacles one of his four taloned limbs. They seemed to hesitate then, the worm leader beside them, the tentacles of the horde waving swiftly still.

Abruptly the tentacles of the leader flashed up as though in a signal. There was a dull ripping sound, and in that moment Randall and Lanier saw the Martian on the block torn literally limb from limb by the four great worm monsters who had held his four limbs!

The tentacles of the horde waved suddenly with increased, excited swiftness at that. Randall shrank in horror.

"They've brought us here for that!" he cried. "To sacrifice us on that altar that way to their worm god!"

But Lanier too had cried out, appalled, as he saw that awful sacrifice, and both strained madly against the grip of the worm creatures. Their struggles were in vain, and then in answer to another unspoken command the two monsters that held Randall were dragging him also to the earthen altar!

He felt himself gripped by the four great creatures around the block, felt as he struggled with his last strength that he was being stretched out on the block, each of the four at one of its corners grasping one of his limbs. He heard Lanier's mad cries as though from a great distance, glimpsed as he was held thus on his back the great shape of the earthen worm god reared over him, and then glimpsed the leader of the monsters rearing beside him.

The dull sound of the swift-waving tentacles of the horde came to him, there was a tense moment of agony of waiting, and then the tentacles of the leader flashed up in the signal!

But at the same moment Randall felt his limbs released by the four monsters that had held them! There seemed sudden wild confusion in the great cave. The strange rite broke off; the horde of worm monsters crawled frantically this way and that in it. Randall slipped off the block; staggered to his feet.

The worm monsters in the cave were swarming toward the downward tunnel openings! The two captives forgotten, the creatures were pouring in crawling, fighting swarms toward those openings. And then, as Randall and Lanier stared stupefied, there came a red flash from one of the upward tunnels and a brilliant crimson ray stabbed down and mowed a path of annihilation in the cave's earthen side!

The two heard great thumping sounds from above, saw the tunnels leading from above becoming suddenly many times greater in size as red rays flashed down along them to gouge the tunnel's walls. Then down from those enlarged tunnels there were bursting long shining shapes, great centipede-machines crawling down the tunnels which their rays made larger before them! And as the centipede-machines burst down into the cavern their crimson rays stabbed right and left to cut paths of annihilation among the worms.

"The Martians!" Lanier cried. "They didn't find us above – they knew we must have been taken by these things – and they've come down after us!"

"Back, Lanier!" Randall shouted. "Quick, before they see us, behind this – "

As he spoke he was jerking Lanier with him behind the looming earthen statue of the great worm god. Crouched there between the statue and the cave's wall they were hidden precariously from the view of those in the cavern. And now that cavern had become a scene of horror unthinkable as the centipede-machines pouring down into it blasted the frantically crawling worm monsters with their rays.

The worm monsters attempted no resistance, but sought only to escape into their downward tunnels, and in moments those not caught by the rays had vanished in the openings. But the centipede-machines, after racing swiftly around the cavity, were following them, were going down into those downward tunnels also, their rays blasting down ahead of each to make the tunnel large enough for them to follow.

In a moment all but one had vanished down into the openings, the remaining one having its front or head jammed in one of the openings from the failure of its operator to blast a large enough opening before him. As Lanier and Randall watched tensely they saw the machine's control room door open and a Martian descend. He inspected the tunnel opening in which his vehicle was jammed, then with a hand ray-tube began to disintegrate the earth around that opening to free his machine.

Randall clutched his companion's arm. "That machine!" he whispered. "If we could capture it, it would give us a chance to get back to the city – to Milton and the matter-transmitter!"

Lanier started, then nodded swiftly. "We'll chance it," he whispered. "For our twenty-four hours here must be almost up."

They hesitated a moment, then crept forward from behind the great earthen statue. The Martian had his back to them, his attention on the freeing of his mechanism. Across the dim-lit cavern they crept softly, and were within a dozen feet of the Martian when some sound made him wheel quickly to confront them with the deadly tube. But even as he whirled the two had leaped.

The force of their leap sent them flying through that dozen feet of space to strike the Martian at the moment his tube levelled. One hissing call he uttered as they struck him, and then with all his strength Lanier had grasped the crocodilian body and bent it backward. Something in it snapped, and the Martian collapsed limply. The two looked wildly around.

Nothing showed that the Martian's call had been heard, and after a moment's glance that showed the head of the centipede machine already freed, they were clambering up into its control room, closing the door. Randall seized the knob with which he had seen the machines operated. As he pulled it toward him the machine moved across the tunnel opening and raced smoothly over the cavern's floor. As he turned the knob the machine turned swiftly in the same direction.

He headed the long mechanism toward one of the upward-curving tunnels which the Martians had blasted larger in descending. They were almost to it when there flashed up into the cavity from one of the downward tunnel openings a centipede-machine, and then another, and another. The Martians in their transparent-windowed control rooms took in at a glance the dead crocodilian on the floor, and then the three great machines were darting toward that of Randall and Lanier.

"The Martian we killed!" Randall cried. "They heard his call and are coming after us!"

"Turn to the wall!" Lanier shouted to him. "I have the rays – "

At that moment there was a clicking beside Randall and he glimpsed Lanier pulling forth two small grips he had found, then saw that two crimson rays were stabbing from tubes in their machine's front toward the others even as their own rays darted back. The beams that had been loosed toward them grazed past them as Randall whirled their machine to the wall, and he saw one of the three attacking mechanisms vanish as Lanier's beams struck it.

Around – back – with instinctive, lightninglike motions he whirled their centipede-machine in the great dim-lit cave as the two remaining ones leapt again to the attack. Their rays shot right and left to catch the two men's vehicle in a trap of death, and as Randall swung their own mechanism straight ahead he glimpsed at the cavern's far end the great earthen worm god still upreared.

On either side of them the red beams burned as they leapt forward, but as though running a gauntlet of death Randall kept the machine racing forward in the succeeding second until the two others loomed on either side of it. Then Lanier's beams were driving in turn to right and left of them and the two vanished as though by magic as they were struck.

"Up to the surface!" Lanier cried, his eyes on the glowing dial of his wrist-watch. "We've been held hours here – we've but a half-hour or more before earth midnight!"

Randall sent their machine racing again toward one of the upward tunnels, and as the long mechanism began to climb smoothly up the darkness he heard Lanier agonizing beside him.

"God, if we have only enough time to get to that matter-transmitter before the Martians start flashing to earth through it!"

"But Milton?" Randall cried. "We don't know whether he's alive or dead! We can't leave him!"

"We must!" said Lanier solemnly. "Our duty's to the earth now, man, to the world that we alone can save from the Martian invasion and conquest! At the hour of twelve Nelson will have the matter-receiver turned on and at that hour the Martian will start flashing to earth – unless we prevent!"

Suddenly Randall grasped the knob in his hands more tightly as light showed above them. They had been climbing upward through the enlarged tunnel at their machine's highest speed, and now as the tunnel curved the light grew stronger. Suddenly they were emerging into the thin sunlight of the Martian day.

In the crimson jungle about them were many Martians, milling excitedly to and fro, and other centipede-machines that were blasting their way down through tunnels to the worm world beneath.

Randall and Lanier, breathless, crouched low in the transparent-windowed control room as they sent their mechanism racing through this scene of swarming activity. Both gasped as one of the centipede-machines clashed against their own in passing, its Martian driver turning to stare after them. But there came no alarm, and in a moment they had passed out of the swarm of Martians and machines and were heading through the jungle in the direction of the city.

Through the weird red vegetation their mechanism raced with them, Randall holding it at its highest speed, and in minutes they came out of the jungle and were racing over the clear space between it and the great canal. Beyond that canal loomed into the thin sunlight the clustering cones of the mighty Martian city, two towering above all the others – the cone of the Martian Master and the other cone in which was the matter-transmitter and receiver.

It was toward the latter that Lanier pointed. "Head straight toward that cone, Randall – we've but minutes left!"

They were racing now up over the great arch of the canal's metal bridge, and then scuttling smoothly off it and along the broad metal street through which they had fled in darkness hours before. In it Martians and centipede-machines were coming and going in great numbers, but none noticed the human forms of the two crouched low in their mechanism's control room.

They were rushing then toward the looming cone of the Martian Master. As they flashed past it Randall saw Lanier's face working, knew the desire that tore at him even as at himself to burst inside and ascertain whether or not Milton still lived in the laboratories from which they had fled. But they were past it, faces white and grim, were rushing on through the Martian city at reckless speed toward the other mighty cone.

It seemed that all in the great city were heading toward the same goal, streams of crocodilian Martians and masses of shining centipede-machines filling the streets as they moved toward it. As they came closer to the mighty structure, hearts pounding, they saw that around it surged a mighty mass of Martians and machines. The hordes waiting to be released through the matter-transmitter inside upon the unsuspecting earth!

"Try to get the machine inside!" Lanier whispered tensely. "If we can smash that transmitter yet…"

Randall nodded grimly. "Keep ready at the ray-tubes," he told the other.

As unobtrusively as possible he sent their long mechanism worming forward through the vast throng of machines and Martians, toward the great cone's door. Crouching low, the hands of their watches closing fast toward the twelfth figure, they edged forward in the long machine. At last they were moving through the mighty door, into the cone's interior.

They moved slowly on through the mass of machines and crocodile forms inside, then halted. For at the great crowd's center was a clear circle hundreds of feet across, and as Randall gazed across it his heart seemed to leap once and then stop.

At the center of that clear circle rose the two cubical metal chambers of the matter-transmitter and receiver. The transmitting chamber, they saw, was flooded with humming force, with white light pouring from its inner walls. It was already in operation, and the masses of Martians in the great cone were only waiting for the moment to sound when the receiver on earth would be operating also. Then they would pour into the chamber to be flashed in masses across the gulf to earth! The eyes of all in the cone seemed turned toward an erect dial-mechanism beside the chambers which was clocklike in appearance, and that would mark the moment when the first Martian could enter the transmitting-chamber and flash out.

A little distance from the two metal chambers stood a low dais on which there sat the hideous triple-bodied form of the Martian Master. Around him were the massed members of his council, waiting like him for the start of their age-planned invasion of earth. And beside the dais was a figure between two crocodilian guards at sight of whom Randall forgot all else.

"Milton! My God, Lanier, it's Milton!"

"Milton! They've brought him here to torture or kill him if they find he's lied about the moment they could flash to earth!"

Milton! And at sight of him something snapped in Randall's brain.

With a single motion of the knob he sent their centipede-machine crashing out into the clear circle at the mighty cone's center. A wild uproar of hissing cries broke from all the thousands in it as he sent the mechanism whirling toward the dais of the Martian Master. He saw the crocodilian forms there scattering blindly before him, and then as his rays drove out and spun and stabbed in mad figures of crimson death through the astounded Martian masses he saw Milton looking up toward them, crying out crazily to them as his two guards loosed him for the moment.

A high call from the Martian Master ripped across the hall and was answered by a shattering roar of hissing voices as Martians and machines surged madly toward them. Randall and Lanier in a single leap were out of the centipede-machine, and in an instant had half-dragged Milton with them in a great leap up to the edge of the humming transmitting chamber.

Milton was shouting hoarsely to them over the wild uproar. To enter that transmitting chamber before the destined moment was annihilation, to be flashed out with no receiver on earth awaiting them. They turned, struck with all their strength at the first Martians rushing up to them. No rays flashed, for a ray loosed would destroy the chamber behind them that was the one gate for the Martians to the world they would invade. But as the Martian Master's high call hissed again all the countless crocodilian forms in the great cone were rushing toward them.

Braced at the very edge of the humming, light-filled chamber, Randall and Lanier and Milton struck madly at the Martians surging up toward them. Randall seemed in a dream. A score of taloned paws clutched him from beneath; scaled forms collapsed under his insane blows.

The whole vast cone and surging reptilian hordes seemed spinning at increasing speed around him. As his clenched fists flashed with waning strength he glimpsed crocodilian forms swarming up on either side of them, glimpsed Lanier down, talons reaching toward him, Milton fighting over him like a madman. Another moment would see it ended – reptilian arms reaching in scores to drag him down – Milton jerking Lanier half to his feet. The Martian Master's call sounded – and then came a great clanging sound at which the Martian hordes seemed to freeze for an instant motionless, at which Milton's voice reached him in a supreme cry.

"Randall – the transmitter!"

For in that instant Milton was leaping back with Lanier, and as Randall with his last strength threw himself backward with them into the humming transmitting-chamber's brilliant light, he heard a last frenzied roar of hissing cries from the Martian hordes about them. Then as the brilliant light and force from the chamber's walls smote them, Randall felt himself hurled into blackness inconceivable, that smashed like a descending curtain across his brain.

The curtain of blackness lifted for a moment. He was lying with Milton and Lanier in another chamber whose force beat upon them. He saw a yellow-lit room instead of the great cone – saw the tense, anxious face of Nelson at the switch beside them. He strove to move, made to Nelson a gesture with his arm that seemed to drain all strength and life from him; and then, as in answer to it Nelson drove up the switch and turned off the force of the matter-receiver in which they lay, the black curtain descended on Randall's brain once more.

Two hours later it was when Milton and Randall and Lanier and Nelson turned to the laboratory's door. They paused to glance behind them. Of the great matter-transmitter and receiver, of the apparatus that had crowded the laboratory, there remained now but wreckage.

For that had been their first thought, their first task, when the astounded Nelson had brought the three back to consciousness and had heard their amazing tale. They had wrecked so completely the matter-station and its actuating apparatus that none could ever have guessed what a mechanism of wonder the laboratory a short time before had held.

The cubical chambers had been smashed beyond all recognition, the dynamos were masses of split metal and fused wiring, the batteries of tubes were shattered, the condensers and transformers and wiring demolished. And it had only been when the last written plans and blue-prints of the mechanism had been burned that Milton and Randall and Lanier had stopped to allow their exhausted bodies a moment of rest.

Now as they paused at the laboratory's door, Lanier reached and swung it open. Together, silent, they gazed out.
