Clifford D. Simak An Anthology

Hellhounds of the Cosmos-2

The scientist's eyes glowed brightly as he bent forward in his chair. The newspaperman said simply: "I have no idea."

"Man," cried the old man, "can't you see that it would be a matter of dimensions? From the fourth dimension to the third, from the third to the second, from the second to the first, from the first to a questionable existence or plane which is beyond our understanding or perhaps to oblivion and the end of life. Might not the fourth have evolved from a fifth, the fifth from a sixth, the sixth from a seventh, and so on to no one knows what multidimension?"

Dr. White paused to allow the other man to grasp the importance of his statements. Woods failed lamentably to do so.

"But what has this to do with the Horror?" he asked.

"Have you absolutely no imagination?" shouted the old man.

"Why, I suppose I have, but I seem to fail to understand."

"We are facing an invasion of fourth-dimensional creatures," the old man whispered, almost as if fearful to speak the words aloud. "We are being attacked by life which is one dimension above us in evolution. We are fighting, I tell you, a tribe of hellhounds out of the cosmos. They are unthinkably above us in the matter of intelligence. There is a chasm of knowledge between us so wide and so deep that it staggers the imagination. They regard us as mere animals, perhaps not even that. So far as they are concerned we are just fodder, something to be eaten as we eat vegetables and cereals or the flesh of domesticated animals. Perhaps they have watched us for years, watching life on the world increase, lapping their monstrous jowls over the fattening of the Earth. They have awaited the proper setting of the banquet table and now they are dining.

"Their thoughts are not our thoughts, their ideals not our ideals. Perhaps they have nothing in common with us except the primal basis of all life, self-preservation, the necessity of feeding.

"Maybe they have come of their own will. I prefer to believe that they have. Perhaps they are merely following the natural course of events, obeying some immutable law legislated by some higher being who watches over the cosmos and dictates what shall be and what shall not be. If this is true it means that there has been a flaw in my reasoning, for I believed that the life of each plane degenerated in company with the degeneration of its plane of existence, which would obey the same evolutional laws which govern the life upon it. I am quite satisfied that this invasion is a well-planned campaign, that some fourth-dimensional race has found a means of breaking through the veil of force which separates its plane from ours."

"But," pointed out Henry Woods, "you say they are fourth-dimensional things. I can't see anything about them to suggest an additional dimension. They are plainly three-dimensional."

"Of course they are three-dimensional. They would have to be to live in this world of three dimensions. The only two-dimensional objects which we know of in this world are merely illusions, projections of the third dimension, like a shadow. It is impossible for more than one dimension to live on any single plane.

"To attack us they would have to lose one dimension. This they have evidently done. You can see how utterly ridiculous it would be for you to try to attack a two-dimensional thing. So far as you were concerned it would have no mass. The same is true of the other dimensions. Similarly a being of a lesser plane could not harm an inhabitant of a higher plane. It is apparent that while the Horror has lost one material dimension, it has retained certain fourth-dimensional properties which make it invulnerable to the forces at the command of our plane."

The newspaperman was now sitting on the edge of his chair.

"But," he asked breathlessly, "it all sounds so hopeless. What can be done about it?"

Dr. White hitched his chair closer and his fingers closed with a fierce grasp upon the other's knee. A militant boom came into his voice.

"My boy," he said, "we are to strike back. We are going to invade the fourth-dimensional plane of these hellhounds. We are going to make them feel our strength. We are going to strike back."

Henry Woods sprang to his feet.

"How?" he shouted. "Have you...?"

Dr. White nodded.

"I have found a way to send the third-dimensional into the fourth. Come and I will show you."

The machine was huge, but it had an appearance of simple construction. A large rectangular block of what appeared to be a strange black metal was set on end and flanked on each side by two smaller ones. On the top of the large block was set a half-globe of a strange substance, somewhat, Henry thought, like frosted glass. On one side of the large cube was set a lever, a long glass panel, two vertical tubes and three clock-face indicators. The control board, it appeared, was relatively simple.

Beside the mass of the five rectangles, on the floor, was a large plate of transparent substance, ground to a concave surface, through which one could see an intricate tangle of wire mesh.

Hanging from the ceiling, directly above the one on the floor, was another concave disk, but this one had a far more pronounced curvature.

Wires connected the two disks and each in turn was connected to the rectangular machine.

"It is a matter of the proper utilization of two forces, electrical and gravitational," proudly explained Dr. White. "Those two forces, properly used, warp the third-dimensional into the fourth. A reverse process is used to return the object to the third. The principle of the machine is—"

The old man was about to launch into a lengthy discussion, but Henry interrupted him. A glance at his watch had shown him press time was drawing perilously close.

"Just a second," he said. "You propose to warp a third-dimensional being into a fourth dimension. How can a third-dimensional thing exist there? You said a short time ago that only a specified dimension could exist on one single plane."

"You have missed my point," snapped Dr. White. "I am not sending a third-dimensional thing to a fourth dimension. I am changing the third-dimensional being into a fourth-dimensional being. I add a dimension, and automatically the being exists on a different plane. I am reversing evolution. This third dimension we now exist on evolved, millions of eons ago, from a fourth dimension. I am sending a lesser entity back over those millions of eons to a plane similar to one upon which his ancestors lived inconceivably long ago."

"But, man, how do you know you can do it?"

The doctor's eyes gleamed and his fingers reached out to press a bell.

A servant appeared almost at once.

"Bring me a dog," snapped the old man. The servant disappeared.

"Young man," said Dr. White, "I am going to show you how I know I can do it. I have done it before, now I am going to do it for you. I have sent dogs and cats back to the fourth dimension and returned them safely to this room. I can do the same with men."

The servant reappeared, carrying in his arms a small dog. The doctor stepped to the control board of his strange machine.

"All right, George," he said.

The servant had evidently worked with the old man enough to know what was expected of him. He stepped close to the floor disk and waited. The dog whined softly, sensing that all was not exactly right.

The old scientist slowly shoved the lever toward the right, and as he did so a faint hum filled the room, rising to a stupendous roar as he advanced the lever. From both floor disk and upper disk leaped strange cones of blue light, which met midway to form an hour-glass shape of brilliance.

The light did not waver or sparkle. It did not glow. It seemed hard and brittle, like straight bars of force. The newspaperman, gazing with awe upon it, felt that terrific force was there. What had the old man said? Warp a third-dimensional being into another dimension! That would take force!

As he watched, petrified by the spectacle, the servant stepped forward and, with a flip, tossed the little dog into the blue light. The animal could be discerned for a moment through the light and then it disappeared.

"Look in the globe!" shouted the old man; and Henry jerked his eyes from the column of light to the half-globe atop the machine.

He gasped. In the globe, deep within its milky center, glowed a picture that made his brain reel as he looked upon it. It was a scene such as no man could have imagined unaided. It was a horribly distorted projection of an eccentric landscape, a landscape hardly analogous to anything on Earth.

"That's the fourth dimension, sir," said the servant.

"That's not the fourth dimension," the old man corrected him. "That's a third-dimensional impression of the fourth dimension. It is no more the fourth dimension than a shadow is three-dimensional. It, like a shadow, is merely a projection. It gives us a glimpse of what the fourth plane is like. It is a shadow of that plane."

Slowly a dark blotch began to grow in the landscape. Slowly it assumed definite form. It puzzled the reporter. It looked familiar. He could have sworn he had seen it somewhere before. It was alive, for it had moved.

"That, sir, is the dog," George volunteered.

"That was the dog," Dr. White again corrected him. "God knows what it is now."

He turned to the newspaperman.

"Have you seen enough?" he demanded.

Henry nodded.

The other slowly began to return the lever to its original position. The roaring subsided, the light faded, the projection in the half-globe grew fainter.

"How are you going to use it?" asked the newspaperman.

"I have ninety-eight men who have agreed to be projected into the fourth dimension to seek out the entities that are attacking us and attack them in turn. I shall send them out in an hour."

"Where is there a phone?" asked the newspaperman.

"In the next room," replied Dr. White.

As the reporter dashed out of the door, the light faded entirely from between the two disks and on the lower one a little dog crouched, quivering, softly whimpering.

The old man stepped from the controls and approached the disk. He scooped the little animal from where it lay into his arms and patted the silky head.

"Good dog," he murmured; and the creature snuggled close to him, comforted, already forgetting that horrible place from which it had just returned.

"Is everything ready, George?" asked the old man.

"Yes, sir," replied the servant. "The men are all ready, even anxious to go. If you ask me, sir, they are a tough lot."

"They are as brave a group of men as ever graced the Earth," replied the scientist gently. "They are adventurers, every one of whom has faced danger and will not shrink from it. They are born fighters. My one regret is that I have not been able to secure more like them. A thousand men such as they should be able to conquer any opponent. It was impossible. The others were poor soft fools. They laughed in my face. They thought I was an old fool—I, the man who alone stands between them and utter destruction."

His voice had risen to almost a scream, but it again sank to a normal tone.

"I may be sending ninety-eight brave men to instant death. I hope not."

"You can always jerk them back, sir," suggested George.

"Maybe I can, maybe not," murmured the old man.

Henry Woods appeared in the doorway.
