"You are really in earnest? You really want to go?" asked the old man, unbelievingly.

  "I am going. Try to stop me."

  Dr. White glanced at his watch.

  "We will start in exactly thirty-four minutes," he said.

  * * * * *

  "Ten seconds to go." George, standing with watch in hand, spoke in a precise manner, the very crispness of his words betraying the excitement under which he labored.

  The blue light, hissing, drove from disk to disk; the room thundered with the roar of the machine, before which stood Dr. White, his hand on the lever, his eyes glued on the instruments before him.

  In a line stood the men who were to fling themselves into the light to be warped into another dimension, there to seek out and fight an unknown enemy. The line was headed by a tall man with hands like hams, with a weather-beaten face and a wild mop of hair. Behind him stood a belligerent little cockney. Henry Woods stood fifth in line. They were a motley lot, adventurers every one of them, and some were obviously afraid as they stood before that column of light, with only a few seconds of the third dimension left to them. They had answered a weird advertisement, and had but a limited idea of what they were about to do. Grimly, though, they accepted it as a job, a bizarre job, but a job. They faced it as they had faced other equally dangerous, but less unusual, jobs.

  "Five seconds," snapped George.

  The lever was all the way over now. The half-globe showed, within its milky interior, a hideously distorted landscape. The light had taken on a hard, brittle appearance and its hiss had risen to a scream. The machine thundered steadily with a suggestion of horrible power.

  "Time up!"

  The tall man stepped forward. His foot reached the disk; another step and he was bathed in the light, a third and he glimmered momentarily, then vanished. Close on his heels followed the little cockney.

  With his nerves at almost a snapping point, Henry moved on behind the fourth man. He was horribly afraid, he wanted to break from the line and run, it didn't matter where, any place to get away from that steady, steely light in front of him. He had seen three men step into it, glow for a second, and then disappear. A fourth man had placed his foot on the disk.

  Cold sweat stood out on his brow. Like an automaton he placed one foot on the disk. The fourth man had already disappeared.

  "Snap into it, pal," growled the man behind.

  Henry lifted the other foot, caught his toe on the edge of the disk and stumbled headlong into the column of light.

  He was conscious of intense heat which was instantly followed by equally intense cold. For a moment his body seemed to be under enormous pressure, then it seemed to be expanding, flying apart, bursting, exploding....

  * * * * *

  He felt solid ground under his feet, and his eyes, snapping open, saw an alien land. It was a land of somber color, with great gray moors, and beetling black cliffs. There was something queer about it, an intangible quality that baffled him.

  He looked about him, expecting to see his companions. He saw no one. He was absolutely alone in that desolate brooding land. Something dreadful had happened! Was he the only one to be safely transported from the third dimension? Had some horrible accident occurred? Was he alone?

  Sudden panic seized him. If something had happened, if the others were not here, might it not be possible that the machine would not be able to bring him back to his own dimension? Was he doomed to remain marooned forever in this terrible plane?

  He looked down at his body and gasped in dismay. It was not his body!

  It was a grotesque caricature of a body, a horrible profane mass of flesh, like a phantasmagoric beast snatched from the dreams of a lunatic.

  It was real, however. He felt it with his hands, but they were not hands. They were something like hands; they served the same purpose that hands served in the third dimension. He was, he realized, a being of the fourth dimension, but in his fourth-dimensional brain still clung hard-fighting remnants of that faithful old third-dimensional brain. He could not, as yet, see with fourth-dimensional eyes, think purely fourth-dimensional thoughts. He had not oriented himself as yet to this new plane of existence. He was seeing the fourth dimension through the blurred lenses of millions of eons of third-dimensional existence. He was seeing it much more clearly than he had seen it in the half-globe atop the machine in Dr. White's laboratory, but he would not see it clearly until every vestige of the third dimension was wiped from him. That, he knew, would come in time.

  He felt his weird body with those things that served as hands, and he found, beneath his groping, unearthly fingers, great rolling muscles, powerful tendons, and hard, well-conditioned flesh. A sense of well-being surged through him and he growled like an animal, like an animal of that horrible fourth plane.

  But the terrible sounds that came from between his slobbering lips were not those of his own voice, they were the voices of many men.

  * * * * *

  Then he knew. He was not alone. Here, in this one body were the bodies, the brains, the power, the spirit, of those other ninety-eight men. In the fourth dimension, all the millions of third-dimensional things were one. Perhaps that particular portion of the third dimension called the Earth had sprung from, or degenerated from, one single unit of a dissolving, worn-out fourth dimension. The third dimension, warped back to a higher plane, was automatically obeying the mystic laws of evolution by reforming in the shape of that old ancestor, unimaginably removed in time from the race he had begot. He was no longer Henry Woods, newspaperman; he was an entity that had given birth, in the dim ages when the Earth was born, to a third dimension. Nor was he alone. This body of his was composed of other sons of that ancient entity.

  He felt himself grow, felt his body grow vaster, assume greater proportions, felt new vitality flow through him. It was the other men, the men who were flinging themselves into the column of light in the laboratory to be warped back to this plane, to be incorporated in his body.

  It was not his body, however. His brain was not his alone. The pronoun, he realized, represented the sum total of those other men, his fellow adventurers.

  Suddenly a new feeling came, a feeling of completeness, a feeling of supreme fitness. He knew that the last of the ninety-eight men had stepped across the disk, that all were here in this giant body.

  Now he could see more clearly. Things in the landscape, which had escaped him before, became recognizable. Awful thoughts ran through his brain, heavy, ponderous, black thoughts. He began to recognize the landscape as something familiar, something he had seen before, a thing with which he was intimate. Phenomena, which his third-dimensional intelligence would have gasped at, became commonplace. He was finally seeing through fourth-dimensional eyes, thinking fourth-dimensional thoughts.

  Memory seeped into his brain and he had fleeting visions, visions of dark caverns lit by hellish flames, of huge seas that battered remorselessly with mile-high waves against towering headlands that reared titanic toward a glowering sky. He remembered a red desert scattered with scarlet boulders, he remembered silver cliffs of gleaming metallic stone. Through all his thoughts ran something else, a scarlet thread of hate, an all-consuming passion, a fierce lust after the life of some other entity.

  He was no longer a composite thing built of third-dimensional beings. He was a creature of another plane, a creature with a consuming hate, and suddenly he knew against whom this hate was directed and why. He knew also that this creature was near and his great fists closed and then spread wide as he knew it. How did he know it? Perhaps through some sense which he, as a being of another plane, held, but which was alien to the Earth. Later, he asked himself this question. At the time, however, there was no questioning on his part. He only knew that somewhere near was a hated enemy and he did not question the source of his knowledge....

  * * * * *

  Mumbling in an idiom incomprehensible to a third-dimensional being, filled with rage that wove redly through his brain, he lumbered down the hi
ll onto the moor, his great strides eating up the distance, his footsteps shaking the ground.

  At the foot of the hill he halted and from his throat issued a challenging roar that made the very crags surrounding the moor tremble. The rocks flung back the roar as if in mockery.

  Again he shouted and in the shout he framed a lurid insult to the enemy that lurked there in the cliffs.

  Again the crags flung back the insult, but this time the echoes, booming over the moor, were drowned by another voice, the voice of the enemy.

  At the far end of the moor appeared a gigantic form, a form that shambled on grotesque, misshapen feet, growling angrily as he came.

  He came rapidly despite his clumsy gait, and as he came he mouthed terrific threats.

  Close to the other he halted and only then did recognition dawn in his eyes.

  "You, Mal Shaff?" he growled in his guttural tongue, and surprise and consternation were written large upon his ugly face.

  "Yes, it is I, Mal Shaff," boomed the other. "Remember, Ouglat, the day you destroyed me and my plane. I have returned to wreak my vengeance. I have solved a mystery you have never guessed and I have come back. You did not imagine you were attacking me again when you sent your minions to that other plane to feed upon the beings there. It was I you were attacking, fool, and I am here to kill you."

  Ouglat leaped and the thing that had been Henry Woods, newspaperman, and ninety-eight other men, but was now Mal Shaff of the fourth dimension, leaped to meet him.

  Mal Shaff felt the force of Ouglat, felt the sharp pain of a hammering fist, and lashed out with those horrible arms of his to smash at the leering face of his antagonist. He felt his fists strike solid flesh, felt the bones creak and tremble beneath his blow.

  His nostrils were filled with the terrible stench of the other's foul breath and his filthy body. He teetered on his gnarled legs and side-stepped a vicious kick and then stepped in to gouge with straightened thumb at the other's eye. The thumb went true and Ouglat howled in pain.

  Mal Shaff leaped back as his opponent charged head down, and his knotted fist beat a thunderous tattoo as the misshapen beast closed in. He felt clawing fingers seeking his throat, felt ghastly nails ripping at his shoulders. In desperation he struck blindly, and Ouglat reeled away. With a quick stride he shortened the distance between them and struck Ouglat a hard blow squarely on his slavering mouth. Pressing hard upon the reeling figure, he swung his fists like sledge-hammers, and Ouglat stumbled, falling in a heap on the sand.

  Mal Shaff leaped upon the fallen foe and kicked him with his taloned feet, ripping him wickedly. There was no thought of fair play, no faintest glimmer of mercy. This was a battle to the death: there could be no quarter.

  * * * * *

  The fallen monster howled, but his voice cut short as his foul mouth, with its razor-edged fangs, closed on the other's body. His talons, seeking a hold, clawed deep.

  Mal Shaff, his brain a screaming maelstrom of weird emotions, aimed pile-driver blows at the enemy, clawed and ripped. Together the two rolled, locked tight in titanic battle, on the sandy plain and a great cloud of heavy dust marked where they struggled.

  In desperation Ouglat put every ounce of his strength into a heave that broke the other's grip and flung him away.

  The two monstrosities surged to their feet, their eyes red with hate, glaring through the dust cloud at one another.

  Slowly Ouglat's hand stole to a black, wicked cylinder that hung on a belt at his waist. His fingers closed upon it and he drew the weapon. As he leveled it at Mal Shaff, his lips curled back and his features distorted into something that was not pleasant to see.

  Mal Shaff, with doubled fists, saw the great thumb of his enemy slowly depressing a button on the cylinder, and a great fear held him rooted in his tracks. In the back of his brain something was vainly trying to explain to him the horror of this thing which the other held.

  Then a multicolored spiral, like a corkscrew column of vapor, sprang from the cylinder and flashed toward him. It struck him full on the chest and even as it did so he caught the ugly fire of triumph in the red eyes of his enemy.

  He felt a stinging sensation where the spiral struck, but that was all. He was astounded. He had feared this weapon, had been sure it portended some form of horrible death. But all it did was to produce a slight sting.

  For a split second he stood stock-still, then he surged forward and advanced upon Ouglat, his hands outspread like claws. From his throat came those horrible sounds, the speech of the fourth dimension.

  "Did I not tell you, foul son of Sargouthe, that I had solved a mystery you have never guessed at? Although you destroyed me long ago, I have returned. Throw away your puny weapon. I am of the lower dimension and am invulnerable to your engines of destruction. You bloated...." His words trailed off into a stream of vileness that could never have occurred to a third-dimensional mind.

  Ouglat, with every line of his face distorted with fear, flung the weapon from him, and turning, fled clumsily down the moor, with Mal Shaff at his heels.

  * * * * *

  Steadily Mal Shaff gained and with only a few feet separating him from Ouglat, he dived with outspread arms at the other's legs.

  The two came down together, but Mal Shaff's grip was broken by the fall and the two regained their feet at almost the same instant.

  The wild moor resounded to their throaty roaring and the high cliffs flung back the echoes of the bellowing of the two gladiators below. It was sheer strength now and flesh and bone were bruised and broken under the life-shaking blows that they dealt. Great furrows were plowed in the sand by the sliding of heavy feet as the two fighters shifted to or away from attack. Blood, blood of fourth-dimensional creatures, covered the bodies of the two and stained the sand with its horrible hue. Perspiration streamed from them and their breath came in gulping gasps.

  The lurid sun slid across the purple sky and still the two fought on. Ouglat, one of the ancients, and Mal Shaff, reincarnated. It was a battle of giants, a battle that must have beggared even the titanic tilting of forgotten gods and entities in the ages when the third-dimensional Earth was young.

  Mal Shaff had no conception of time. He may have fought seconds or hours. It seemed an eternity. He had attempted to fight scientifically, but had failed to do so. While one part of him had cried out to elude his opponent, to wait for openings, to conserve his strength, another part had shouted at him to step in and smash, smash, smash at the hated monstrosity pitted against him.

  It seemed Ouglat was growing in size, had become more agile, that his strength was greater. His punches hurt more; it was harder to hit him.

  Still Mal Shaff drilled in determinedly, head down, fists working like pistons. As the other seemed to grow stronger and larger, he seemed to become smaller and weaker.

  It was queer. Ouglat should be tired, too. His punches should be weaker. He should move more slowly, be heavier on his feet.

  There was no doubt of it. Ouglat was growing larger, was drawing on some mysterious reserve of strength. From somewhere new force and life were flowing into his body. But from where was this strength coming?

  A huge fist smashed against Mal Shaff's jaw. He felt himself lifted, and the next moment he skidded across the sand.

  Lying there, gasping for breath, almost too fagged to rise, with the black bulk of the enemy looming through the dust cloud before him, he suddenly realized the source of the other's renewed strength.

  Ouglat was recalling his minions from the third dimension! They were incorporating in his body, returning to their parent body!

  They were coming back from the third dimension to the fourth dimension to fight a third-dimensional thing reincarnated in the fourth-dimensional form it had lost millions of eons ago!

  This was the end, thought Mal Shaff. But he staggered to his feet to meet the charge of the ancient enemy and a grim song, a death chant immeasurably old, suddenly and dimly remembered from out of the mists of countless millenniums, was on his lip
s as he swung a pile-driver blow into the suddenly astonished face of the rushing Ouglat....

  * * * * *

  The milky globe atop the machine in Dr. White's laboratory glowed softly, and within that glow two figures seemed to struggle.

  Before the machine, his hands still on the controls, stood Dr. Silas White. Behind him the room was crowded with newspapermen and photographers.

  Hours had passed since the ninety-eight men--ninety-nine, counting Henry Woods--had stepped into the brittle column of light to be shunted back through unguessed time to a different plane of existence. The old scientist, during all those hours, had stood like a graven image before his machine, eyes staring fixedly at the globe.

  Through the open windows he had heard the cry of the newsboy as the Press put the greatest scoop of all time on the street. The phone had rung like mad and George answered it. The doorbell buzzed repeatedly and George ushered in newspapermen who had asked innumerable questions, to which he had replied briefly, almost mechanically. The reporters had fought for the use of the one phone in the house and had finally drawn lots for it. A few had raced out to use other phones.

  Photographers came and flashes popped and cameras clicked. The room was in an uproar. On the rare occasions when the reporters were not using the phone the instrument buzzed shrilly. Authoritative voices demanded Dr. Silas White. George, his eyes on the old man, stated that Dr. Silas White could not be disturbed, that he was busy.

  From the street below came the heavy-throated hum of thousands of voices. The street was packed with a jostling crowd of awed humanity, every eye fastened on the house of Dr. Silas White. Lines of police held them back.

  "What makes them move so slowly?" asked a reporter, staring at the globe. "They hardly seem to be moving. It looks like a slow motion picture."

  "They are not moving slowly," replied Dr. White. "There must be a difference in time in the fourth dimension. Maybe what is hours to us is only seconds to them. Time must flow more slowly there. Perhaps it is a bigger place than this third plane. That may account for it. They aren't moving slowly, they are fighting savagely. It's a fight to the death! Watch!"
