He waited to quiet the trembling of his hands, and then began to move the director's knobs. The integrator's long needle swung, as silently as light.
Human eyes were blind to that force, which might detonate a planet. Human ears were deaf to it. The cathoderay tube was mounted in the director cabinet, to make the faraway target visible to feeble human senses.
The needle was pointing at the kitchen wall, but that would be transparent to the beam. The little machine looked harmless as a toy, and it was silent as a moving humanoid.
The needle swung, and spots of greenish light moved across the tube's fluorescent field, representing the stars that were scanned by the timeless, searching beam—silently seeking out the world to be destroyed.
Underhill recognized familiar constellations, vastly dwarfed. They crept across the field, as the silent needle swung. When three stars formed an unequal triangle in the center of the field, the needle steadied suddenly. Sledge touched other knobs, and the green points spread apart. Between them, another fleck of green was born.
"The Wing!" whispered Sledge.
The other stars spread beyond the field, and that green fleck grew. It was alone in the field, a bright and tiny disk. Suddenly, then, a dozen other tiny pips were visible, spaced close about it.
"Wing IV!"
The old man's whisper was hoarse and breathless. His hands quivered on the knobs, and the fourth pip outward from the disk crept to the center of the field. It grew, and the others spread away. It began to tremble like Sledge's hands.
"Sit very still," came his rasping whisper. "Hold your breath. Nothing must disturb the needle." He reached for another knob, and the touch set the greenish image to dancing violently. He drew his hand back, kneaded and flexed it with the other.
"Now!" His whisper was hushed and strained. He nodded at the window. "Tell me when they stop."
Reluctantly, Underhill dragged his eyes from that intense gaunt figure, stooped over the thing that seemed a futile toy. He looked out again, at two or three little black mechanicals busy about the shining roofs across the alley.
He waited for them to stop.
He didn't dare to breathe. He felt the loud, hurried hammer of his heart, and the nervous quiver of his muscles. He tried to steady himself, tried not to think of the world about to be exploded, so far away that the flash would not reach this planet for another century and longer. The loud hoarse voice startled him:
"Have they stopped?"
He shook his head, and breathed again. Carrying their unfamiliar tools and strange materials, the small black machines were still busy across the alley, building an elaborate cupola above that glowing crimson dome.
"They haven't stopped," he said.
"Then we've failed." The old man's voice was thin and ill. "I don't know why."
The door rattled, then. They had locked it, but the flimsy bolt was intended only to stop men. Metal snapped, and the door swung open. A black mechanical came in, on soundless graceful feet. Its silvery voice purred softly:
"At your service, Mr. Sledge."
The old man stared at it, with glazing, stricken eyes.
"Get out of here!" he rasped bitterly. "I forbid you—"
Ignoring him, it darted to the kitchen table. With a flashing certainty of action, it turned two knobs on the director. The tiny screen went dark, and the palladium needle started spinning aimlessly. Deftly it snapped a soldered connection, next to the thick lead ball, and then its blind steel eyes turned to Sledge.
"You were attempting to break the Prime Directive." Its soft bright voice held no accusation, no malice or anger. "The injunction to respect your freedom is subordinate to the Prime Directive, as you know, and it is therefore necessary for us to interfere."
The old man turned ghastly. His head was shrunken and cadaverous and blue, as if all the juice of life had been drained away, and his eyes in their pitlike sockets had a wild, glazed stare. His breath was a ragged laborious gasping.
"How—?" His voice was a feeble mumbling. "How did—?"
And the little machine, standing black and bland and utterly unmoving, told him cheerfully:
"We learned about rhodomagnetic screens from that man who came to kill you, back on Wing IV. And the Central is shielded, now, against your integrating beam."
With lean muscles jerking convulsively on his gaunt frame, old Sledge had come to his feet from the high stool. He stood hunched and swaying, no more than a shrunken human husk, gasping painfully for life, staring wildly into the blind steel eyes of the humanoid. He gulped, and his lax blue mouth opened and closed, but no voice came.
"We have always been aware of your dangerous project," the silvery tones dripped softly, "because now our senses are keener than you made them. We allowed you to complete it, because the integration process will ultimately become necessary for our full discharge of the Prime Directive. The supply of heavy metals for our fission plants is limited, but now we shall be able to draw unlimited power from integration plants."
"Huh?" Sledge shook himself, groggily. "What's that?"
"Now we can serve men forever," the black thing said serenely, "on every world of every star."
The old man crumpled, as if from an unendurable blow. He fell. The slim blind mechanical stood motionless, making no effort to help him. Underhill was farther away, but he ran up in time to catch the stricken man before his head struck the floor.
"Get moving!" His shaken voice came strangely calm. "Get Dr. Winters."
The humanoid didn't move.
"The danger to the Prime Directive is ended, now," it cooed. "Therefore it is impossible for us to aid or to hinder Mr. Sledge, in any way whatever."
"Then call Dr. Winters for me," rapped Underhill.
"At your service," it agreed.
But the old man, laboring for breath on the floor, whispered faintly:
"No time . . . no use! I'm beaten . . . done . . . a fool. Blind as a humanoid. Tell them . . . to help me. Giving up . . . my immunity. No use . . . anyhow. All humanity . . . no use now."
Underhill gestured, and the sleek black thing darted in solicitous obedience to kneel by the man on the floor.
"You wish to surrender your special exemption?" it murmured brightly. "You wish to accept our total service for yourself, Mr. Sledge, under the Prime Directive?"
Laboriously, Sledge nodded, laboriously whispered: "I do."
Black mechanicals, at that, came swarming into the shabby little rooms. One of them tore off Sledge's sleeve, and swabbed his arm. Another brought a tiny hypodermic, and expertly administered an intravenous injection. Then they picked him up gently, and carried him away.
Several humanoids remained in the little apartment, now a sanctuary no longer. Most of them had gathered about the useless integrator. Carefully, as if their special senses were studying every detail, they began taking it apart.
One little mechanical, however, came over to Underhill. It stood motionless in front of him, staring through him with sightless metal eyes. His legs began to tremble, and he swallowed uneasily.
"Mr. Underhill," it cooed benevolently, "why did you help with this?"
He gulped and answered bitterly:
"Because I don't like you, or your Prime Directive. Because you're choking the life out of all mankind, and I wanted to stop it."
"Others have protested," it purred softly. "But only at first. In our efficient discharge of the Prime Directive, we have learned how to make all men happy."
Underhill stiffened defiantly.
"Not all!" he muttered. "Not quite!"
The dark graceful oval of its face was fixed in a look of alert benevolence and perpetual mind amazement. Its silvery voice was warm and kind.
"Like other human beings, Mr. Underhill, you lack discrimination of good and evil. You have proved that by your effort to break the Prime Directive. Now it will be necessary for you to accept our total service, without further delay."
"All right," he yielded—and muttered a bitter
reservation: "You can smother men with too much care, but that doesn't make them happy."
Its soft voice challenged him brightly:
"Just wait and see, Mr. Underhill."
Next day, he was allowed to visit Sledge at the city hospital. An alert black mechanical drove his car, and walked beside him into the huge new building, and followed him into the old man's room—blind steel eyes would be watching him, now, forever.
"Glad to see you, Underhill," Sledge rumbled heartily from the bed. "Feeling a lot better today, thanks. That old headache is all but gone."
Underhill was glad to hear the booming strength and the quick recognition in that deep voice—he had been afraid the humanoids would tamper with the old man's memory. But he hadn't heard about any headache. His eyes narrowed, puzzled.
Sledge lay propped up, scrubbed very clean and neatly shorn, with his gnarled old hands folded on top of the spotless sheets. His rawboned cheeks and sockets were hollowed, still, but a healthy pink had replaced that deathly blueness. Bandages covered the back of his head.
Underhill shifted uneasily.
"Oh!" he whispered faintly. "I didn't know—"
A prim black mechanical, which had been standing statue like behind the bed, turned gracefully to Underhill, explaining:
"Mr. Sledge has been suffering for many years from a benign tumor of the brain, which his human doctors failed to diagnose. That caused his headaches, and certain persistent hallucinations. We have removed the growth, and now the hallucinations have also vanished."
Underhill stared uncertainly at the blind, urbane mechanical.
"What hallucinations?"
"Mr. Sledge thought he was a rhodomagnetic engineer," the mechanical explained. "He believed he was the creator of the humanoids. He was troubled with an irrational belief that he did not like the Prime Directive."
The wan man moved on the pillows, astonished.
"Is that so?" The gaunt face held a cheerful blankness, and the hollow eyes flashed with a merely momentary interest. "Well, whoever did design them, they're pretty wonderful. Aren't they, Underhill?"
Underhill was grateful that he didn't have to answer, for the bright, empty eyes dropped shut and the old man fell suddenly asleep. He felt the mechanical touch his sleeve, and saw its silent nod. Obediently, he followed it away.
Alert and solicitous, the little black mechanical accompanied him down the shining corridor, and worked the elevator for him, and conducted him back to the car. It drove him efficiently back through the new and splendid avenues, toward the magnificent prison of his home.
Sitting beside it in the car, he watched its small deft hands on the wheel, the changing luster of bronze and blue on its shining blackness. The final machine, perfect and beautiful, created to serve mankind forever. He shuddered.
"At your service, Mr. Underhill." Its blind steel eyes stared straight ahead, but it was still aware of him. "What's the matter, sir? Aren't you happy?"
Underhill felt cold and faint with terror. His skin turned clammy, and a painful prickling came over him. His wet hand tensed on the door handle of the car, but he restrained the impulse to jump and run. That was folly. There was no escape. He made himself sit still.
"You will be happy, sir," the mechanical promised him cheerfully. "We have learned how to make all men happy, under the Prime Directive. Our service is perfect, at last. Even Mr. Sledge is very happy now."
Underhill tried to speak, and his dry throat stuck. He felt ill. The world turned dim and gray. The humanoids were perfect—no question of that. They had even learned to be, to secure the contentment of men.
He knew they had lied. That was no tumor they had removed from Sledge's brain, but the memory, the scientific knowledge, and the bitter disillusion of their own creator. But it was true that Sledge was happy now.
He tried to stop his own convulsive quivering.
"A wonderful operation!" His voice came forced and faint. "You know, Aurora has had a lot of funny tenants, but that old man was the absolute limit. The very idea that he had made the humanoids, and he knew how to stop them! I always knew he must be lying!"
Stiff with terror, he made a weak and hollow laugh.
"What is the matter, Mr. Underhill?" The alert mechanical must have perceived his shuddering illness. "Are you unwell?"
"No, there's nothing the matter with me," he gasped desperately. "I've just found out that I'm perfectly happy, under the Prime Directive. Everything is absolutely wonderful." His voice came dry and hoarse and wild. "You won't have to operate on me."
The car turned off the shining avenue, taking him back to the quiet splendor of his home. His futile hands clenched and relaxed again, folded on his knees. There was nothing left to do.
The Great Fog
H. F. Heard
—
The first symptom was a mildew.
Very few people have ever looked carefully at such “molds”; indeed, only a specialized branch of botanists knows about them. Nor is this knowledge—except rarely—of much use. Every now and then a low growth of this sort may attack a big cash crop. Then the mycologists, whose lifework is to study these spore growths, are called in by the growers. These botanists can sometimes find another mold which will eat its fellow. That closes the matter. The balance of life, which had been slightly upset, has been righted. It is not a matter of any general interest.
This particular mildew did not seem to have even that special importance. It did not, apparently, do any damage to the trees on which it grew. Indeed, most fruit growers never noticed it. The botanists found it themselves; no one called their attention to it. It was simply a form of spore growth different in its growth rate from any previously recorded. It did not seem to do any harm to any other form of life. But it did do amazingly well for itself. It was not a new plant, but a plant with quite a new power of growth.
It was this fact which puzzled the botanists, or rather that special branch of the botanists, the mycologists. That was why they finally called in the meteorologists. They asked for “another opinion,” as baffled doctors say. What made the mycologists choose the meteorologists for consultation was this: Here was a mildew which spread faster than any other mold had ever been known to grow. It flourished in places where such mildews had been thought incapable of growing. But there seemed to be no botanical change either in the mold or in the plants it grew on. Therefore the cause must be climatic: only a weather change could account for the unprecedented growth.
The meteorologists saw the force of this argument. They became interested at once. The first thing to do, they said, was to study the mildew, not as a plant, but as a machine, an indicator. “You know,” said Sersen the weatherman to Charles the botanist (they had been made colleagues for the duration of the study), “the astronomers have a thing called a thermocouple that will tell the heat of a summer day on the equator of Mars. Well, here is a little gadget I’ve made. It’s almost as sensitive to damp as the thermocouple is to heat.”
Sersen spent some time rigging it up and then “balancing” it, as he called it. “Find the normal humidity and then see how much the damp at a particular spot exceeds that.” But he went on fiddling about far longer than Charles thought an expert who was handling his own gadget should. He was evidently puzzled. And after a while he confessed that he was.
“Queer, very queer,” said Sersen. “Of course, I expected to get a good record of humidity around the mold itself. As you say, it can’t grow without that: it wouldn’t be here unless the extra damp was here too. But, look here,” he said, pointing to a needle that quivered near a high number on a scale. “That is the humidity actually around the mold itself—what we might expect, if a trifle high. That’s not the surprise. It’s this.” He had swung the whole instrument on its tripod until it pointed a foot or more from the mold; for the tree they were studying was a newly attacked one and, as far as Charles had been able to discover, had on it only this single specimen of the mildew.
Charles looked at th
e needle. It remained hovering about the high figure it had first chosen. “Well?” he queried.
“Don’t you see?” urged Sersen. “This odd high humidity is present not only around the mold itself but for more than a foot beyond.”
“I don’t see much to that.”
“I see two things,” snapped Sersen; “one’s odd; the other’s damned odd. The odd one anyone not blind would see. The other one is perhaps too big to be seen until one can stand well back.”
“Sorry to be stupid,” said Charles, a gentle-spoken but close-minded little fellow; “we botanists are small-scale men.”
“Sorry to be a snapper,” apologized Sersen. “But, as I suppose you’ve guessed, I’m startled. I’ve got a queer feeling that we’re on the track of something big, yes, and something maybe moving pretty fast. The first odd thing isn’t a complete surprise: it’s that you botanists have shown us what could turn out to be a meteorological instrument more delicate and more accurate than any we have been able to make. Perhaps we ought to have been on the outlook for some such find. After all, living things are always the most sensitive detectors—can always beat mechanical instruments when they want to. You know about the mitogenetic rays given out by breeding seeds. Those rays can be recorded only by yeast cells—which multiply rapidly when exposed to the rays, thus giving an indication of their range and strength.”
“Umph,” said Charles. Sersen’s illustration had been unfortunate, for Charles belonged to that majority of conservative botanists to whom the mitogenetic radiation was mere moonshine.
Sersen, again vexed, went on: “Well, whether you accept them or not, I still maintain that here we have a superdetector. This mildew can notice an increase in humidity long before any of our instruments. There’s proof that something has changed in the climate. This mold is the first to know about it—and to profit by it. I prophesy it will soon be over the whole world.”
“But your second discovery, or supposition?” Charles had no use for prophecy. These weathermen, he thought; well, after all, they aren’t quite scientists, so one mustn’t blame them, one supposes, for liking forecasts—forecasting is quite unscientific.
