Part 2

Chandler tossed his pencil aside and stood up. "Nor is there any need to get a decision at this moment. The drill--with or without the capsule--will be basically the same. I'd like to see a motion for work to proceed on the drill. The matter of the X-factor can be decided later."

"I make such a motion," said the Canadian.

The motion was passed.

It was Marta who selected the site. She chose a grassy meadow in northern Michigan that stood directly in the path of the advancing glacier. But long before the first fingers of the glacier could search out the site, searing billows of heat would spread like a spider web across the mountain heights and northern reaches of North America, the north Atlantic and northwestern Europe.

Only Marta's stubborn insistence that this was the most central location had worn down a number of European delegates who had wanted operations to begin on their side of the Atlantic.

Kotenko, with a green light from Chandler, ordered three long-abandoned automotive plants into action in Michigan. Scientists and technicians from many nations of the World Council were brought together in the old General Motors Technical Center in Detroit. Plans were drawn, models constructed and a test vehicle sent to the center of Saturn's moon, Mimas.

* * * * *

Chandler carefully studied Kotenko's report of the Mimas probe, then met with the Russian in the latter's office.

"I know why you're here," said Kotenko, offering Chandler a black Russian cigar. "You must take into consideration that this was only a scale model."

"But it had full power," Chandler argued.

"The initial descent was held to fifty miles an hour." Kotenko lit Chandler's cigar. "A fast start and we would have done it with power to spare. And remember that we haven't licked the heat problem. The test drill was softened by friction heat."

"You still couldn't have made it to the center of Rhea, let alone to the core of the Earth," Chandler said.

"It can be done," Kotenko insisted, "and without resorting to your X-factor."

"I've requested a special meeting of the World Council together with the committee to clear the way for using the X-factor."

"I'll oppose it. Since I am in full charge of constructing the drill, my words will bear some weight."

"I doubt if you will object," Chandler said. "I've just received a report from the State Department. They have good reason to believe that your government will back the release of one capsule."

Kotenko stared at Chandler. Finally he rotated his cigar in his fingers and studied the burning end. "Then I'll resign."

"No, you won't. Your government wouldn't permit it." He smiled at the Russian. "And neither would I. You're too valuable a man."

Kotenko was still studying his cigar as Chandler left.

* * * * *

The X-factor capsule arrived under an international guard with the blessings of slightly over half of the member nations. Kotenko didn't resign, but his friendliness vanished.

That same day, Marta broke in on Chandler and, to the consternation of his secretary, hugged him.

"We've done it!" she cried.

"Here, here, take it easy." He held her at arm's length. "All right, what have we done?"

"Remember the things you said to me about slowing down the molecular activity of metals?"

Chandler nodded.

"Well," she continued, "we've just had a major breakthrough in the metallurgical lab, once you showed us the way. We can practically remove all of the heat conductivity. In less than a month we can start manufacture of the conduits."

Chandler smiled. The last obstacle was over.

"And more than that," Marta said, "we can build a test drill that will go down into one of the big moons--one with a molten core."

"The next drill," said Chandler, "will be the _real_ thing to tap the core of the Earth."

Marta kissed him.

The drill took less than the projected year to build. On the grassy Michigan meadow, as several hundred dignitaries, reporters and curious spectators in wind-whipped overcoats were held in check by armed troops, the giant device was lowered toward a concrete basin. Sizzling arc lights mounted on the control ring, a circular concrete building surrounding the basin, illuminated the scene against the growing darkness of night.

The Soviet press was lauding the drill as a Russian achievement. Most Western papers gave the credit to Dr. Paul Chandler. But Chandler knew it was Kotenko's idea, made possible by his own mental resources, surprising even to himself.

Chandler felt a deep pride as he gazed at the drill, complete with the controversial capsule.

* * * * *

"Excuse me, Dr. Chandler." A reporter with dry, unkempt hair stepped up. "I still don't see how that thing will work."

"In simple words, the rock is drawn into the bottom something like air into a jet engine," said Chandler. "The rock is vaporized and expelled out the top where the vapor together with the device itself presses the molten material into the walls of the shaft. Because the rock has had its heat conductivity removed, it hardens and remains permanently solid. A tubular force field keeps the shaft from collapsing."

"I understand that much." The reporter took out a folded square of paper and a pencil. "But what makes the thing go?"

"It has a gravity drive, giving it many times its normal weight." Marta Neilson had moved up to Chandler's elbow. "It simply sinks toward the center of the Earth like a pebble sinking in a pond of water."

"What is your reaction to Senator Caldwell's remark that the administration is at last returning all of the nation's gold into a hole in the ground?"

Chandler laughed. "Don't get me mixed up in politics."

"Are you disturbed by the Interplanetary Council of Churches' charge that any attempt to stop the glacier is defying the will of God?"

"Nor religion, either, please."

"Then maybe you'll discuss your own field," the reporter said. "Are you aware of the petition signed by thousands of African and Middle Eastern scientists?"

"I've read about it," Chandler admitted.

"Do you feel that taking an X-bomb into the center of the Earth is completely safe?"

"Nothing is completely safe." Chandler pointed to the reporter's feet. "The ground may give way under your feet right now, but I'd bet my life that it won't."

The reporter studied the ground under his feet, then scribbled a few words on his paper. A moment later, he spotted Kotenko and excused himself.

Marta gave Paul's hand a firm squeeze and he squeezed back. Dr. White stepped up and offered his congratulations, adding the suggestion that perhaps now they should turn their attention to destroying the Bering Strait Dam. Chandler parried the question and the Englishman left to exchange pleasantries with the Indian delegate, who was engaged in an animated conversation with several committee members.

"Well," said Marta, smiling up at Chandler, "tomorrow's the big day."

"Worries me," Chandler said.

"You mean the composition of the core?"

Chandler nodded at the drill. "Basically, that thing is an X-bomb. If fusion were to occur in the core and that core _were_ made up of compacted hydrogen atoms, I think the Earth might crack apart along the fault lines surrounding the Pacific Ocean basin."

"What could cause fusion?" Marta asked.

"Losing control from the surface."

"How do you mean?"

"Well, it'll tax the abilities of the controllers every minute," Chandler explained, "to compensate for variations in density and gravity. If that thing got away from them, even for a few moments, its velocity could build to a point where it would hit the center of the Earth's gravity at the speed of a meteor."

Marta's eyes opened wide. "And, of course, it would stop almost instantaneously."

"Most of the energy of its forward motion would be converted to heat, which would develop a temperature far more than enough to trigger the thing," Chandler said.

"But it's made of non-conductive alloys," Marta said.

"Which would only make it happen quicker by reflecting the heat back in on itself."

* * * * *

The press photographers' strobe lights began to flicker as the drill was lowered into the center of the control ring. Someone was making a speech, thin sounds wavering across the meadow, as Chandler and Marta started walking toward the VIP geodesic dome, where most of the top scientists were quartered.

Marta stared at Chandler for a moment. "Why didn't you say something about this to me, Paul? Now I know why Kotenko favored hydrogen fusion without the X-factor."

"It wouldn't have done the job," Chandler said. "Just not enough controllable power."

"Kotenko thought so."

"He was wrong."

"Then why did you insist upon the drill? Surely some of the other methods were workable. What about India's suggestion to set off a number of H-bombs underground to produce pockets of magma? That would have produced plenty of tappable heat."

"I don't know," was Chandler's honest answer. "Call it a hunch or a premonition, but I think it's the drill or nothing. Once the core is tapped, the danger is over; we won't have to drill any more holes. We'll have an unending source of heat, and non-conductive conduits to pump it anywhere on Earth."

"Paul," Marta said, "I've always gone along with you on just about everything. Maybe the fact that I'm a woman has been outweighing the fact that I'm also a scientist. But let's talk now about the moral obligation of a scientist."

"I'm interested in one thing--the best method to save civilization from certain destruction."

"But have you the right to gamble like this? Which is worse, the destruction of civilization or the destruction of the Earth?"

"Marta," he said, "man at last stands at the brink of fulfilling his destiny. He is already establishing colonies on two planets and within a hundred years will have a firm foothold in the Solar System. In the millennia that follow, the Galaxy will be his."

Marta stopped in horror. "That sounds like Colonial talk!"

Chandler smiled reassuringly. "In this case, what's best for the Colonies is also best for the Mother Planet."

"But surely there's time to halt operations long enough to try some of the other methods first."

"If we were to falter now," said Chandler as they began walking again, "politicians would have most of us replaced inside of twenty-four hours. Would you like to see that drill start its plunge to the core without someone on hand who knows how to handle it?"

"No, I wouldn't," Marta said. "I'm not sure I want to see it start at all." She touched his arm. "Paul, this is a side of you I've tried hard not to see. You're--you're almost obsessed with the belief that the drill is the only answer. And you're battling ruthlessly against counter-ideas and time. After all, even the most radical estimates give us at least two more centuries. Granted there'll be a southern migration, but--"

"Don't ask me how I know," Chandler said, "but we don't have two or even one century. _We don't have ten years!_ When the ice cap at the South Pole was at its peak, it exerted tremendous pressures on the continental land masses."

"The old shifting crust theory?"

"Yes. A theory tossed into discard when the big thaw came at the South Pole. Now, at an almost unbelievable rate, the ice is building in the north. This same seesawing effect has gone on throughout the Pleistocene. The stresses go one way against the crustal blocks of land, then the other way. It might be likened to bending a wire one way, then the other, until fatigue causes it to snap."

"And you're convinced that the crust is about to let go?"

"With catastrophic consequences."

"You're asking me to accept a great deal on faith."

"When you stood by me back in New San Francisco," Chandler asked, "did you honestly think we could tap the core?"

"I don't know," Marta answered.

"Would you have supported me if I had backed the Canadian plan for tilting the world on its axis?"

* * * * *

Marta seemed lost in deep reflection for a few moments. "I don't really know," she said as they reached the VIP quarters.

At Marta's door, Chandler asked, "Will you stand by me for another twenty-four hours? By that time, the drill will be cushioning to a stop exactly two thousand miles down."

"Unless we lose control," Marta said. "Then, in less than an hour, it could be smashing into the center of the core."

"Will you wait?"

For an answer she kissed him on the cheek, then said softly, "Now we better both get some rest. We start operations in less than six hours." She closed her door.

Chandler entered his room and stretched out on his cot without taking his clothes off. He thought about the plans he had ignored. Some of them might have done the job. He thought of Kotenko, who distrusted him, and Marta, who trusted him. Finally he drifted into sleep.

He dreamed of great cracks snaking their way down city streets, of violent earthquakes, foaming tidal waves, of people trapped in crumbling buildings and, finally, the Earth blooming into another sun.

And as the fireball expanded into oblivion, the shimmering face of the short man appeared. His mouth moved, but Paul sensed rather than heard his words.

"Chandler. Kotenko and the drill."

The face faded to nothing.

Chandler sat bolt upright on the cot. He was dripping with perspiration. The drill! Something was wrong at the drill.

He ran down the hall to Marta's room and rapped on the door.

"Who is it?" Marta's voice called out.

"Paul."

There was a pause. Then the door opened, revealing Marta fastening a negligee.

"Did I oversleep?" she asked, yawning.

"Have you seen Kotenko?"

"No, but I heard him talking to someone in the hall just after you left. It sounded like that reporter."

"Did Kotenko go into his room?"

"I don't know."

Chandler, followed by Marta, continued down the hall to Kotenko's room. He knocked loudly. There was no answer. He knocked again and shouted Kotenko's name. Other doors opened and people stared out.

"The drill," Chandler said, and ran out of the building. As the door swung closed, he heard Marta calling after him. He was conscious of someone pushing through the door behind him as he bounded across the meadow toward the drill.

A small Army verti-plane swung down alongside him.

"Halt!" an amplified voice boomed.

Chandler stopped and faced the plane. "It's me, Dr. Chandler."

The plane settled down beside him. "Oh, yes, sir," the voice apologized. "We saw you running and--"

"Quick, take me to the drill," Chandler said.

"Yes, sir," said the voice.

The verti-plane floated down beside the massive control ring and Chandler, followed by two armed soldiers, raced through the main doors.

"Halt."

Guards surrounded them.

"Has Kotenko been here?" asked Chandler.

"Yes, sir," replied one of the guards recognizing Chandler. "He took a team of technicians to the Gismo."

"Follow me," Chandler ordered, and pushed through the inner door.

Hesitantly, the guards followed.

* * * * *

Down in the basin, Chandler saw the yellow glow of a work light. Figures were silhouetted against it. He took the spiral stairs two at a time. The soldiers clambered down behind him.

"Stay where you are, Chandler," said the voice of Kotenko, his stocky figure back-lighted at the base of the drill.

"What're you doing, Kotenko?" Chandler demanded,

"Removing the X-factor capsule."

"You're tampering with government property," Chandler said, primarily to orientate the confused guards.

"I am not going to permit the drill to go down there with the X-factor," Kotenko said firmly.

"It'll never get beyond the thousand-mile level," Chandler warned, moving toward the shadowy figure.

"I am armed," Kotenko warned.

* * * * *

Chandler stopped. Marta, clad in an overcoat, came down the stairs. Several others followed.

"Those techs will never do it now that they know the situation," Chandler said, moving still closer.

"My dear Dr. Chandler, they are citizens of the Soviet. They will do as I say."

"Put down your gun," the soldier at Chandler's side ordered.

"I have already set up the drill for descent," Kotenko said. His shadow hand touched a black lever on a portable field control unit. "As soon as the X-factor capsule is withdrawn, down it goes."

"But you can never maintain control without a full crew," Marta said.

"I have crew enough," Kotenko told her. "Without the X-factor, complete control is not so important."

Chandler leaped for Kotenko, but the Russian's gun blasted white flame. A searing pain ripped into Chandler's chest. He fell to his knees.

The soldier's rifle cracked and Kotenko's silhouette crumbled against the control lever. Electro-mechanisms whirred and the drill suddenly plunged into the depths of the Earth, carrying most of Kotenko's crew with it.

"Good God!" someone cried.

Marta was kneeling beside Chandler, tears streaming down her face. "Paul!" she sobbed. "Oh, Paul!"

Chandler could taste the warm saltiness of blood in his mouth. "Get the control crew here--quick," he gasped.

Someone moved for the stairs while someone else leaped for the field control unit.

Chandler's foggy mind touched reality for brief moments, condensing time into a montage. A doctor was working on him, then shaking his head at the sobbing Marta. Lights were thrown on and control posts manned. Someone yelled, "Throw in force fields behind it!" And all the time Chandler's chest pulsed with pain.

"Can't stop it!" someone shouted. Then chaos broke loose; men were running, blindly bumping into one another.

Even though few of them knew quite what could happen, they wanted to get as far away from the hole as they could.

Marta was rocking Paul gently in her arms and crooning something Swedish. The ground trembled under them, then lurched violently. Sheets of broken plate glass rained down on them from the control ring windows. Chandler knew the same thing was happening everywhere as the shock waves from the drill reverberated around the globe.

He looked around. They were alone on the basin floor except for the contorted body of Kotenko. Paul looked up at Marta.

"How--much--time?"

Marta, her face close to his, smiled faintly. "No more time for you and me." Her eyes were dry.

A sound as of millions of giant rocks grating together welled up from the bowels of the Earth. He was looking into Marta's eyes when suddenly everything vaporized into blinding white heat.

"Clench your fingers."

"Blink your eyes."

* * * * *

The short man in the gleaming laboratory was leaning over Chandler. "We did our best," he said.

The pain was gone in Chandler's chest. "Marta," he called.

"I'm afraid she's gone," the tall man said. "She and the entire Earth."

The short man pulled off his lab coat. "Over a thousand years ago."

"A thousand years?" Chandler's mind fumbled with the thought. "What's this all about?"

The tall man snapped a series of switches off. "You ask the same question every time."

"_Every_ time?"

"We've sent you back three times now." The tall man traded his lab coat for a tunic. "Once you tried to X-bomb the Bering Strait Dam, but the crust shifted, wiping out the whole population. On the second time pass, you tried to tilt the Earth on its axis, but it was thrown out of orbit and plunged into the sun. This time--you still have your memories of that."

"Makes you wonder about fate," the short man said.

"But what am I?" Chandler sat up with an effort.

"You," explained the short man, "are a mind developed here in a Venus laboratory and sustained in a host body. You see, we can't send solid matter back in time, only waves moving at the speed of light. So we send your mind matrix to meld with Chandler's."

"But why?"

"To help him save the Earth," the tall man said. "When it was destroyed originally, small colonies of us were stranded on inhospitable planets. We're still trying to crawl out of the decline that set in. But if we can send you back and save the Earth--well, you will remain with Paul Chandler. And we--?" He walked to a bank of controls near the door and put his hand on one. "Who knows? None of this will have happened. We might not even exist."

"Now," said the short man, joining the taller one, "we will have to wipe out all memories for you and tomorrow we will start programming you for another try. Maybe this time we'll try moving the Earth's orbit closer to the sun."

"Wipe out my memories?"

"Of course. We want you to function with a clear mind. Besides, it's kinder to you."

"I see." The mind named Chandler looked at the two men. "But please leave me with my memories just for tonight."

The tall man turned off the light. "You always ask that and we always do."
