The Best of Clifford D. Simak

  Russ grinned, but it was a sour one.

  "No use," said Greg. "Chambers would tie us up in a mile of legal red tape. It would be just like walking up and handing it to him."

  "You guys go ahead and work," Wilson stated. "I'm taking a vacation. Three months is too damn long to stay out in a spaceship."

  "It doesn't seem long to me," said Greg, his tone cold and sharp.

  No, thought Russ, it hadn't seemed long. Perhaps the hours had been rough, the work hard, but he hadn't noticed. Sleep and food had come in snatches. For three months they had worked in space, not daring to carry out their experiments on Earth... frankly afraid of the thing they had.

  He glanced at Manning.

  The three months had left no mark upon him, no hint of fatigue or strain. Russ understood now how Manning had done the things he did. The man was all steel and flame. Nothing could touch him.

  "We still have a lot to do," said Manning.

  Russ leaned back and puffed at his pipe.

  Yes, there was a lot to do. Transmission problems, for instance. To conduct away such terrific power as they knew they were capable of developing would require copper or silver bars as thick as a man's thigh, and even so at voltages capable of jumping a two-foot spark gap.

  Obviously, a small machine such as they now had would be impractical. No matter how perfectly it might be insulated, the atmosphere itself would not be an insulator, with power such as this. And if one tried to deliver the energy as a mechanical rotation of a shaft, what shaft could transmit it safely and under control?

  "Oh, hell," Russ burst out, "let's get back to Earth."

  Harry Wilson watched the couple alight from the aero-taxi, walk up the broad steps and pass through the magic portals of the Martian Club. He could imagine what the club was like, the deference of the management, the exotic atmosphere of the dining room, the excellence of the long, cold drinks served at the bar. Mysterious drinks concocted of ingredients harvested in the jungles of Venus, spiced with produce from the irrigated gardens of Mars.

  He puffed on the dangling cigarette and shuffled on along the airy highwalk. Below and above him, all around him flowed the beauty and the glamor, the bravery and the splendor of New York. The city's song was in his ears, the surging noises that were its voice.

  Two thousand feet above his head reared giant pinnacles of shining metal, glinting in the noonday Sun, architecture that bore the alien stamp of other worlds.

  Wilson turned around, stared at the Martian Club. A man needed money to pass through those doors, to taste the drinks that slid across its bar, to sit and watch its floor shows, to hear the music of its orchestras.

  For a moment he stood, hesitating, as if he were trying to make up his mind. He flipped away the cigarette, turned on his heel, walked briskly to the automatic elevator which would take him to the lower levels.

  There, on the third level, he entered a Mecho restaurant, sat down at a table and ordered from the robot waiter, pushing ivory-tipped buttons on the menu before him.

  He ate leisurely, smoked ferociously, thinking. Looking at his watch, he saw that it was nearly two o'clock. He walked to the cashier machine, inserted the metallic check with the correct change and received from the clicking, chuckling register the disk that would let him out the door.

  "Thank you, come again," the cashier-robot fluted.

  "Don't mention it," growled Wilson.

  Outside the restaurant he walked briskly. Ten blocks away he came to a building roofing four square blocks. Over the massive doorway, set into the beryllium steel, was a map of the Solar System, a map that served as a cosmic clock, tracing the movement of the planets as they swung in their long arcs around the Sun. The Solar System was straddled by glowing, golden letters. They read: interplanetary building.

  It was from here that Spencer Chambers ruled his empire built on power.

  Wilson went inside.

  CHAPTER FOUR

  The new apparatus was set up, a machine that almost filled the laboratory... a giant, compact mass of heavy, solidly built metal work, tied together by beams of girderlike construction. It was meant to stand up under the hammering of unimaginable power, the stress of unknown spatial factors.

  Slowly, carefully, Russell Page tapped keys on the control board, setting up an equation. Sucking thoughtfully at his pipe, he checked and rechecked them.

  Harry Wilson regarded him through squinted eyes.

  "What the hell is going to happen now?" he asked.

  "We'll have to wait and see," Russ answered. "We know what we want to happen, what we hope will happen, but we never can be sure. We are working with conditions that are entirely new."

  Sitting beside a table littered with papers, staring at the gigantic machine before him, Gregory Manning said slowly: "That thing simply has to adapt itself to spaceship drive. There's everything there that's needed for space propulsion. Unlimited power from a minimum of fuel. Splitsecond efficiency. Entire independence of any set condition, because the stuff creates its own conditions."

  He slowly wagged his head.

  "The secret is some place along the line," he declared. "I feel that we must be getting close to it."

  Russ walked from the control board to the table, picked up a sheaf of papers and leafed through them. He selected a handful and shook them in his fist.

  "I thought I had it here," he said. "My math must have been wrong, some factor that I didn't include in the equation."

  "You'll keep finding factors for some time yet," Greg prophesied.

  "Repulsion would have been the answer," said Russ bitterly. "And the Lord knows we have it. Plenty of it."

  "Too much," observed Wilson, smoke drooling from his nostrils.

  "Not too much," corrected Greg. "Inefficient control. You jump at conclusions, Wilson."

  "The math didn't show that progressive action," said Russ. "It showed repulsion, negative gravity that could be built up until it would shoot the ship outside the Solar System within an hour's time. Faster than light. We don't know how many times faster."

  "Forget it," advised Greg. "The way it stands, it's useless. You get repulsion by progressive steps. A series of squares with one constant factor. It wouldn't be any good for space travel. Imagine trying to use it on a spaceship. You'd start with a terrific jolt. The acceleration would fade and just when you were recovering from the first jolt, you'd get a second one and that second one would iron you out. A spaceship couldn't take it, let alone a human body."

  "MAYBE this will do it," said Wilson hopefully.

  "Maybe," agreed Russ. "Anyhow we'll try it. Equation 578."

  "It might do the trick," said Greg. "It's a new approach to the gravity angle. The equation explains the shifting of gravitational lines, the changing and contortion of their direction. Twist gravity and you have a perfect space drive. As good as negative gravity. Better, perhaps, more easily controlled. Would make for more delicate, precise handling."

  Russ laid down the sheaf of papers, lit his pipe and walked to the apparatus.

  "Here goes," he said.

  His hand went out to the power lever, eased it in. With a roar the material energy engine built within the apparatus surged into action, sending a flow of power through the massive leads. The thunder mounted in the room. The laboratory seemed to shudder with the impact. Wilson, watching intently, cried out, a brief, choked-off cry. A wave of dizziness engulfed him. The walls seemed to be falling in. The room and the machine were blurring. Russ, at the controls, seemed horribly disjointed. Manning was a caricature of a man, a weird, strange figure that moved and gestured in the mad room.

  Wilson fought against the dizziness. He tried to take a step and the floor seemed to leap up and meet his outstretched foot, throwing him off balance. His cigarette fell out of his mouth, rolled along the floor.

  Russ was shouting something, but the words were distorted, loud one instant, rising over the din of the apparatus, a mere whisper the next. They made no se
nse.

  There was a peculiar whistling in the air, a sound such as he had never heard before. It seemed to come from far away, a high, thin shriek that was torture in one's ears.

  Giddy, seized with deathly nausea, Wilson clawed his way across the floor, swung open the laboratory door and stumbled outdoors. He weaved across the lawn and clung to a sun dial, panting.

  He looked back at the laboratory and gasped in disbelief. All the trees were bent toward the building, as if held by some mighty wind. Their branches straining, every single leaf standing at rigid attention, the trees were bending in toward the structure. But there was no wind.

  And then he noticed something else. No matter where the trees stood, no matter in what direction from the laboratory, they all bent inward toward the building... and the whining, thundering, shrieking machine.

  Inside the laboratory an empty bottle crashed off a table and smashed into a thousand fragments. The tinkling of the broken glass was a silvery, momentary sound that protested against the blasting thrum of power that shook the walls.

  Manning fought along the floor to Russ' side. Russ roared in his ear: "Gravitational control! Concentration of gravitational lines!"

  The papers on the desk started to slide, slithering onto the floor, danced a crazy dervish across the room. Liquids in the laboratory bottles were climbing the sides of glass, instead of lying at rest parallel with the floor. A chair skated, bucking and tipping crazily, toward the door.

  * * *

  Russ jerked the power lever back to zero. The power hum died. The liquids slid back to their natural level, the chair tipped over and lay still, papers fluttered gently downward.

  The two men looked at one another across the few feet of floor space between them. Russ wiped beads of perspiration from his forehead with his shirt sleeve. He sucked on his pipe, but it was dead.

  "Greg," Russ said jubilantly, "we have something better than anti-gravity! We have something you might call positive gravity... gravity that we can control. Your grandfather nullified gravity. We've gone him one better."

  Greg gestured toward the machine. "You created an attraction center. What else?"

  "But the center itself is not actually an attracting force. The fourth dimension is mixed up in this. We have a sort of fourth-dimensional lens that concentrates the lines of any gravitational force. Concentration in the fourth dimension turns the force loose in three dimensions, but we can take care of that by using mirrors of our anti-entropy. We can arrange it so that it turns the force loose in only one dimension."

  Greg was thoughtful for a moment. "We can guide a ship by a series of lenses," he declared at last. "But here's the really important thing. That field concentrates the forces of gravity already present. Those forces exist throughout all of space. There are gravitational lines everywhere. We can concentrate them in any direction we want to. In reality, we fall toward the body which originally caused the force of gravitation, not to the concentration."

  * * *

  Russ nodded. "That means we can create a field immediately ahead of the ship. The ship would fall into it constantly, with the concentration moving on ahead. The field would tend to break down in proportion to the strain imposed and a big ship, especially when you are building up speed, would tend to enlarge it, open it up. But the field could be kept tight by supplying energy and we have plenty of that... far more than we'd ever need. We supply the energy, but that's only a small part of it. The body emitting the gravitational force supplies the fulcrum that moves us along."

  "It would operate beyond the planets," said Greg. "It would operate equally well anywhere in space, for all of space is filled with gravitational stress. We could use gravitational bodies many light years away as the driver of our ships."

  A half-wild light glowed momentarily in his eyes.

  "Russ," he said, "we're going to put space fields to work at last."

  He walked to the chair, picked it up and sat down in it.

  "We'll start building a ship," he stated, "just as soon as we know the mechanics of this gravity concentration and control. Russ, we'll build the greatest ship, the fastest ship, the most powerful ship the Solar System has ever known!"

  "DAMN," said, Russ, that thing's slipped again."

  He glared at the offending nut. "I'll put a lock washer on it this time."

  Wilson stepped toward the control board. From his perch on he apparatus, Russ motioned him away.

  "Never mind discharging the field," he said. "I can get around it somehow."

  Wilson squinted at him. "This tooth is near killing me."

  "Still got a toothache?" asked Russ.

  "Never got a wink of sleep last night."

  "You better run down to Frisco and have it yanked out," suggested the scientist. "Can't have you laid up."

  "Yeah, that's right," agreed Wilson. "Maybe I will. We got a lot to do."

  Russ reached out and clamped his wrench on the nut, quickly backed it off and slipped on the washer. Viciously he tightened it home. The wrench stuck.

  Gritting his teeth on the bit of his pipe, Russ cursed soundlessly. He yanked savagely at the wrench. It slipped from his hand, hung for a minute on the nut and then plunged downward, falling straight into the heart of the new force field they had developed.

  Russ froze and watched, his heart in his throat, mad thoughts in his brain. In a flash, as the wrench fell, he remembered that they knew nothing about this field. All they knew was that any matter introduced in it suddenly acquired an acceleration in the dimension known as time, with its normal constant of duration reduced to zero.

  When that wrench struck the field, it would cease to exist! But something else might happen, too, something entirely unguessable.

  The wrench fell only a few feet, but it seemed to take long seconds as Russ watched, frozen in fascination.

  He saw it strike the hazy glow that defined the limits of the field, saw it floating down, as if its speed had been slowed by some dense medium.

  In the instant that hazy glow intensified a thousand times--became a blinding sun-burst! Russ ducked his head, shielded his eyes from the terrible blast of light. A rending, shuddering thud seemed to echo... in space rather than in air... and both field and wrench were gone!

  A moment passed, then another, and there was the heavy, solid clanging thud of something striking metal. This time the thud was not in space, but a commonplace noise, as if someone had dropped a tool on the floor above.

  Russ turned around and stared at Wilson. Wilson stared back, his mouth hanging open, the smoldering, cigarette dangling from his mouth.

  "Greg!" Russ shouted, his cry shattering the silence in the laboratory.

  A door burst open and Manning stepped into the main laboratory room, a calculation pad in one hand, a pencil in the other.

  "What's the matter?" he demanded.

  "We have to find my wrench!"

  "Your wrench?" Greg was puzzled. "Can't you get another?"

  "I dropped it into the field. Its time-dimension was reduced to zero. It became an 'instantaneous wrench'."

  "Nothing new in that," said Greg, unruffled.

  "But there is," persisted Russ. "The field collapsed, you see. Maybe the wrench was too big for it to handle. And when the field collapsed the wrench gained a new time-dimension. I heard it. We have to find it."

  The three of them pounded up the stairs to the room where Russ had heard the thump. There was nothing on the floor. They searched the room from end to end, then the other rooms. There was no wrench.

  At the end of an hour Greg went back to the main laboratory, brought back a portable fluoroscope.

  "Maybe this will do the trick," he announced bleakly.

  IT did. They found the wrench inside the space between the walls!

  Russ stared at the shadow in the fluoroscope plate. Undeniably it was the shadow of the wrench.

  "Fourth dimension," he said. "Transported in time."

  The muscles in Greg's cheeks were tensed, that ol
d flame of excitement burning in his eyes, but otherwise his face was the mask of old, the calm, almost terrible mask that had faced a thousand dangers.

  "Power and time," he corrected.

  "If we can control it," said Russ.

  "Don't worry. We can control it. And when we can, it's the biggest thing we've got."

  Wilson licked his lips, dredged a cigarette out of a pocket.

  "If you don't mind," he said, "I'll hit for Frisco tonight. This tooth of mine is getting worse."

  "Sure, can't keep an aching tooth," agreed Russ, thinking of the wrench while talking.

  "Can I take your ship?" asked Wilson.

  "Sure," said Russ.

  Back in the laboratory they rebuilt the field, dropped little ball bearings in it. The ball bearings disappeared. They found them everywhere--in the walls, in tables, in the floor. Some, still existing in their new time-dimension, hung in mid-air, invisible, intangible, but there.

  Hours followed hours, with the sheet of data growing. Math machines whirred and chuckled and clicked. Wilson departed for San Francisco with his aching tooth. The other two worked on. By dawn they knew what they were doing out of the chaos of happenstance they were finding rules of order, certain formulas of behavior, equations of force.

  The next day they tried heavier, more complicated things and learned still more.

  A radiogram, phoned from the nearest spaceport, forty miles distant, informed them that Wilson would not be back for a few days. His tooth was worse than he had thought, required an operation and treatment of the jaw.

  "Hell," said Russ, "just when he could be so much help."

  With Wilson gone the two of them tackled the controlling device, labored and swore over it. But finally it was completed.

  Slumped in chairs, utterly exhausted, they looked proudly at it.

  "With that," said Russ, "we can take an object and transport it any place we want. Not only that, we can pick up any object from an indefinite distance and bring it to us."

  "What a thing for a lazy burglar," Greg observed sourly.

  Worn out, they gulped sandwiches and scalding coffee, tumbled into bed.
