The Best of Clifford D. Simak Page 2

  IT was Gregory Manning who had financed and headed the rescue expedition which took the first Pluto flight off that dark icebox of a world when the exploration ship had crashed. It was he who had piloted home the winning ship in the Jupiter derby, sending his bulleting craft screaming around the mighty planet in a time which set a Solar record. It was Gregory Manning who had entered the Venusian swamps and brought back, alive, the mystery lizard that had been reported there. And he was the one who had flown the serum to Mercury when the lives of ten thousand men depended upon the thrumming engines that drove the shining ship inward toward the Sun.

  Russell Page had known him since college days. They had worked out their experiments together in the school laboratories, had spent long hours arguing and wondering... debating scientific theories. Both had loved the same girl, both had lost her, and together they had been bitter over it... drowning their bitterness in a three-day drunk that made campus history.

  After graduation Gregory Manning had gone on to world fame, had roamed over the face of every planet except Jupiter and Saturn, had visited every inhabited moon, had climbed Lunar mountains, penetrated Venusian swamps, crossed Martian deserts, driven by a need to see and experience that would not let him rest. Russell Page had sunk into obscurity, had buried himself in scientific research, coming more and more to aim his effort at the discovery of a new source of power... power that would be cheap, that would destroy the threat of Interplanetary dictatorship.

  Page turned away from the rectifier room.

  "Maybe I'll have something to show Greg soon," he told himself. "Maybe, after all these years...."

  * * *

  Forty minutes after Page put through the call to Chicago, Gregory Manning arrived. The scientist, watching for him from the tiny lawn that surrounded the combined home and laboratory, saw his plane bullet into sight, scream down toward the little field and make a perfect landing.

  Hurrying toward the plane as Gregory stepped out of it Russell noted that his friend looked the same as ever, though it had been a year or more since he had seen him. The thing that was discomfiting about Greg was his apparently enduring youthfulness.

  He was clad in jodhpurs and boots and an old tweed coat, with a brilliant blue stock at his throat. He waved a hand in greeting and hurried forward. Russ heard the grating of his boots across the gravel of the walk.

  Greg's face was bleak; it always was. A clean, smooth face, hard, with something stern about the eyes.

  His grip almost crushed Russ's hand, but his tone was crisp. "You sounded excited, Russ."

  "I have a right to be," said the scientist. "I think I have found something at last."

  "Atomic power?" asked Manning. There was no flutter of excitement in his voice, just a little hardening of the lines about his eyes, a little tensing of the muscles in his cheeks.

  Russ shook his head. "Not atomic energy. If it's anything, it's material energy, the secret of the energy of matter."

  They halted before two lawn chairs.

  "Let's sit down here," invited Russ. "I can tell it to you out here, show it to you afterward. It isn't often I can be outdoors."

  "It is a fine place," said Greg. "I can smell the pines."

  The laboratory perched on a ledge of rugged rock, nearly 7,000 feet above sea level. Before them the land swept down in jagged ruggedness to a valley far below, where a stream flashed in the noonday Sun. Beyond climbed pine-clad slopes and far in the distance gleamed shimmering spires of snow-capped peaks.

  From his leather jacket Russ hauled forth his pipe and tobacco, lighted up.

  "It was this way," he said. Leaning back comfortably he outlined the first experiment. Manning listened intently.

  "Now comes the funny part," Russ added. "I had hopes before, but I believe this is what put me on the right track. I took a metal rod, a welding rod, you know. I pushed it into that solidified force field, if that is what you'd call it... although that doesn't describe it. The rod went in. Took a lot of pushing, but it went in. And though the field seemed entirely transparent, you couldn't see the rod, even after I had pushed enough of it in so it should have come out the other side. It was as if it hadn't entered the sphere of force at all. As if I were just telescoping the rod and its density were increasing as I pushed, like pushing it back into itself, but that, of course, wouldn't have been possible."

  He paused and puffed at his pipe, his eyes fixed on the snowy peaks far in the purple distance. Manning waited.

  "Finally the rod came out," Russ went on. "Mind you, it came out, even after I would have sworn, if I had relied alone upon my eyes, that it hadn't entered the sphere at all. But it came out ninety degrees removed from its point of entry!"

  "Wait a second," said Manning. "This doesn't check. Did you do it more than once?"

  "I did it a dozen times and the results were the same each time. But you haven't heard the half of it. When I pulled that rod out--yes, I could pull it out--it was a good two inches shorter than when I had pushed it in. I couldn't believe that part of it. It was even harder to believe than that the rod should come out ninety degrees from its point of entry. I measured the rods after that and made sure. Kept an accurate record. Every single one of them lost approximately two inches by being shoved into the sphere. Every single one of them repeated the phenomenon of curving within the sphere to come out somewhere else than where I had inserted them."

  "ANY explanation of it?" asked Manning, and now there was a cold chill of excitement in his voice.

  "Theories, no real explanations. Remember that you can't see the rod after you push it into the sphere. It's just as if it isn't there. Well, maybe it isn't. You can't disturb anything within that sphere or you'd change the sum of potential-kinetic-pressure energies within it. The sphere seems dedicated to that one thing... it cannot change. If the rod struck the imperm wire within the field, it would press the wire down, would use up energy, decrease the potential energy. So the rod simply had to miss it somehow. I believe it moved into some higher plane of existence and went around. And in doing that it had to turn so many corners, so many fourth-dimensional corners, that the length was used up. Or maybe it was increased in density. I'm not sure. Perhaps no one will ever know."

  "Why didn't you tell me about this sooner?" demanded Manning. "I should have been out here helping you. Maybe I wouldn't be much good, but I might have helped."

  "You'll have your chance," Russ told him. "We're just starting. I wanted to be sure I had something before I troubled you. I tried other things with that first sphere. I found that metal pushed through the sphere will conduct an electrical current, which is pretty definite proof that the metal isn't within the sphere at all. Glass can be forced through it without breaking. Not flexible glass, but rods of plain old brittle glass. It turns without breaking, and it also loses some of its length. Water can be forced through a tube inserted in the sphere, but only when terrific pressure is applied. What that proves I can't even begin to guess."

  "You said you experimented on the first sphere," said Manning. "Have you made others?"

  Russ rose from his chair.

  "Come on in, Greg," he said, and there was a grin on his face. "I have something you'll have to see to appreciate."

  * * *

  The apparatus was heavier and larger than the first in which Russ had created the sphere of energy. Fed by a powerful accumulator battery, five power leads were aimed at it, centered in the space between four great copper blocks.

  Russ's hand went out to the switch that controlled the power. Suddenly the power beams flamed, changed from a dull glow into an intense, almost intolerable brilliance. A dull grumble of power climbed up to a steady wail.

  The beams had changed color, were bluish now, the typical color of ionized air. They were just power beams, meeting at a common center, but somehow they were queer, too, for though they were capable of slashing far out into space, they were stopped dead. Their might was pouring into a common center and going no farther. A splash of intens
ely glowing light rested over them, then began to rotate slowly as a motor somewhere hummed softly, cutting through the mad roar and rumble of power that surged through the laboratory.

  The glowing light was spinning more swiftly now. A rotating field was being established. The power beams began to wink, falling and rising in intensity. The sphere seemed to grow, almost filling the space between the copper blocks. It touched one and rebounded slightly toward another. It extended, increased slightly. A terrible screaming ripped through the room, drowning out the titanic din as the spinning sphere came in contact with the copper blocks, as force and metal resulted in weird friction.

  With a shocking wrench the beams went dead, the scream cut off, the roar was gone. A terrifying silence fell upon the room as soon as the suddenly thunking relays opened automatically.

  * * *

  The sphere was gone! In its place was a tenuous refraction that told where it had been. That and a thin layer of perfectly reflective copper... colorless now, but Manning knew it was copper, for it represented the continuation of the great copper blocks.

  His mind felt as if it were racing in neutral, getting nowhere. Within that sphere was the total energy that had been poured out by five gigantic beams, turned on full, for almost a minute's time. Compressed energy! Energy enough to blast these mountains down to the primal rock were it released instantly. Energy trapped and held by virtue of some peculiarity of that little borderline between Force Fields 348 and 349.

  Russ walked across the room to a small electric truck with rubber caterpillar treads, driven by a bank of portable accumulators. Skillfully the scientist maneuvered it over to the other side of the room, picked up a steel bar four inches in diameter and five feet long. Holding it by the handler's magnetic crane, he fixed it firmly in the armlike jaws on the front of the machine, then moved the machine into a position straddling the sphere of force.

  With smashing momentum the iron jaws thrust downward, driving the steel bar into the sphere. There was a groaning crash as the handler came to a halt, shuddering, with only eight inches of the bar buried in the sphere. The stench of hot insulation filled the room while the electric motor throbbed, the rubber treads creaked, the machine groaned and strained, but the bar would go no farther.

  Russ shut off the machine and stood back.

  "That gives you an idea," he said grimly.

  "The trick now," Greg said, "is to break down the field."

  Without a word, Russ reached for the power controls. A sudden roar of thunderous fury and the beams leaped at the sphere... but this time the sphere did not materialize again. Again the wrench shuddered through the laboratory, a wrench that seemed to distort space and time.

  Then, as abruptly as it had come, it was gone. But when it ended, something gigantic and incomprehensibly powerful seemed to rush soundlessly by... something that was felt and sensed. It was like a great noiseless, breathless wind in the dead of night that rushed by them and through them, all about them in space and died slowly away.

  But the vanished steel did not reappear with the disappearance of the sphere and the draining away of power. Almost grotesquely now, the handler stood poised above the place where the sphere had been and in its jaws it held the bar. But the end of the bar, the eight inches that had been within the sphere, was gone. It had been sliced off so sharply that it left a highly reflective concave mirror on the severed surface.

  "Where is it?" demanded Manning. "In that higher dimension?"

  Russ shook his head. "You noticed that rushing sensation? That may have been the energy of matter rushing into some other space. It may be the key to the energy of matter!"

  Gregory Manning stared at the bar. "I'm staying with you, Russ. I'm seeing this thing through."

  "I knew you would," said Russ.

  Triumph flamed briefly in Manning's eyes. "And when we finish, we'll have something that will break Interplanetary. We'll smash their stranglehold on the Solar System." He stopped and looked at Page. "Lord, Russ," he whispered, "do you realize what we'll have?"

  "I think I do, Greg," the scientist answered soberly. "Material energy engines. Power so cheap that you won't be able to give it away. More power than anybody could ever need."

  CHAPTER THREE

  Russ hunched over the keyboard set in the control room of The Comet and stared down at the keys. The equation was set and ready. All he had to do was tap that key and they would know, beyond all argument, whether or not they had dipped into the awful heart of material energy; whether, finally, they held in their grasp the key to the release of energy that would give the System power to spare.

  His glance lifted from the keyboard, looked out the observation port. Through the inkiness of space ran a faint blue thread, a tiny line that stretched from the ship and away until it was lost in the darkness of the void.

  One hundred thousand miles away, that thread touched the surface of a steel ball bearing... a speck in the immensity of space.

  He thought about that little beam of blue. It took power to do that, power to hold a beam tight and strong and steady through the stress of one hundred thousand miles. But it had to be that far away... and they had that power. From the bowels of the ship came the deep purr of it, the angry, silky song of mighty engines throttled down.

  He heard Harry Wilson shuffling impatiently behind him, smelled the acrid smoke that floated from the tip of Wilson's cigarette.

  "Might as well punch that key, Russ," said Manning's cool voice. "We have to find out sooner or later."

  Russ's finger hovered over the key, steadied and held. When he punched that key, if everything worked right, the energy in the tiny ball bearing would be released instantaneously. The energy of a piece of steel, weighing less than an ounce. Over that tight beam of blue would flash the impulse of destruction....

  His fingers plunged down.

  Space flamed in front of them. For just an instant the void seemed filled with an angry, bursting fire that lapped with hungry tongues of cold, blue light toward the distant planets. A flare so intense that it was visible on the Jovian worlds, three hundred million miles away. It lighted the night-side of Earth, blotting out the stars and Moon, sending astronomers scurrying for their telescopes, rating foot-high streamers in the night editions.

  Slowly Russ turned around and faced his friend.

  "We have it, Greg," he said. "We really have it. We've tested the control formulas all along the line. We know what we can do."

  "We don't know it all yet," declared Greg. "We know we can make it work, but I have a feeling we haven't more than skimmed the surface possibilities."

  * * *

  Russ sank into a chair and stared about the room. They knew they could generate alternating current of any frequency they chose by use of a special collector apparatus. They could release radiant energy in almost any quantity they desired, in any wave-length, from the longest radio to the incredibly hard cosmics. The electrical power they could measure accurately and easily by simple voltmeters and ammeters. But radiant energy was another thing. When it passed all hitherto known bonds, it would simply fuse any instrument they might use to measure it.

  But they knew the power they generated. In one split second they had burst the energy bonds of a tiny bit of steel and that energy had glared briefly more hotly than the Sun.

  "Greg," he said, "it isn't often you can say that any event was the beginning of a new era. You can with this--the era of unlimited power. It kind of scares me."

  Up until a hundred years ago coal and oil and oxygen had been the main power sources, but with the dwindling of the supply of coal and oil, man had sought another way. He had turned back to the old dream of snatching power direct from the Sun. In the year 2048 Patterson had perfected the photocell. Then the Alexanderson accumulators made it possible to pump the life-blood of power to the far reaches of the System, and on Mercury and Venus, and to a lesser extent on Earth, great accumulator power plants had sprung up, with Interplanetary, under the driving genius of Spe
ncer Chambers, gaining control of the market.

  The photocell and the accumulator had spurred interplanetary trade and settlement. Until it had been possible to store Sun-power for the driving of spaceships and for shipment to the outer planets, ships had been driven by rocket fuel, and the struggling colonies on the outer worlds had fought a bitter battle without the aid of ready power.

  Coal and oil there were in plenty on the outer worlds, but one other essential was lacking... oxygen. Coal on Mars, for instance, had to burned under synthetic air pressures, like the old carburetor. The result was inefficiency. A lot of coal burned, not enough power delivered.

  Even the photocells were inefficient when attempts were made to operate them beyond the Earth that was the maximum distance for maximum Solar efficiency.

  Russ dug into the pocket of his faded, scuffed leather jacket and hauled forth pipe and pouch. Thoughtfully he tamped the tobacco into the bowl.

  "Three months," he said. "Three months of damn hard work."

  "Yeah," agreed Wilson, "we sure have worked."

  Wilson's face was haggard, his eyes red. He blew smoke through his nostrils.

  "When we get back, how about us taking a little vacation?" he asked.

  Russ laughed. "You can if you want to. Greg and I are keeping on."

  "We can't waste time," Manning said. "Spencer Chambers may get wind of this. He'd move all hell to stop us."

  Wilson spat out his cigarette. "Why don't you patent what you have? That would protect you."
