Now he was only fifty feet away, and closing rapidly. There might never be a better chance. He punched the launching stud.
From beneath the belly of the sub, something that looked like a sting-ray hurtled forward. Don had checked the speed of his own craft; there was no need to come any closer now. The tiny, arrow-shaped hydrofoil, only a couple of feet across, could move far faster than his vessel and would close the gap in seconds. As it raced forward, it spun out the thin line of the control wire, like some underwater spider laying its thread. Along that wire passed the energy that powered the Sting, and the signals that steered it to its goal. Don had completely ignored his own larger craft in the effort of guiding this underwater missile. It responded to his touch so swiftly that he felt he was controlling some sensitive high-spirited steed.
The shark saw the danger less than a second before impact. The resemblance of the Sting to an ordinary ray confused it, as the designers had intended. Before the tiny brain could realize that no ray behaved like this, the missile had struck. The steel hypodermic, rammed forward by an exploding cartridge, drove through the shark’s horny skin, and the great fish erupted in a frenzy of terror. Don backed rapidly away, for a blow from that tail would rattle him around like a pea in a can and might even cause damage to the sub. There was nothing more for him to do, except to speak into the microphone and call off his hounds.
The doomed killer was trying to arch its body so that it could snap at the poisoned dart. Don had now reeled the Sting back into its hiding place, pleased that he had been able to retrieve the missile undamaged. He watched without pity as the great fish succumbed to its paralysis.
Its struggles were weakening. It was swimming aimlessly back and forth, and once Don had to sidestep smartly to avoid a collision. As it lost control of buoyancy, the dying shark drifted up to the surface. Don did not bother to follow; that could wait until he had attended to more important business.
He found the cow and her two calves less than a mile away, and inspected them carefully. They were uninjured, so there was no need to call the vet in his highly specialized two-man sub which could handle any cetological crisis from a stomach-ache to a Caesarian. Don made a note of the mother’s number, stencilled just behind the flippers. The calves, as was obvious from their size, were this season’s and had not yet been branded.
Don watched for a little while. They were no longer in the least alarmed, and a check on the sonar had shown that the whole school had ceased its panicky flight. He wondered how they knew what had happened; much had been learned about communication among whales, but much was still a mystery.
“I hope you appreciate what I’ve done for you, old lady,” he muttered. Then, reflecting that fifty tons of mother love
was a slightly awe-inspiring sight, he blew his tanks and surfaced.
It was calm, so he cracked the airlock and popped his head out of the tiny conning tower. The water was only inches below his chin, and from time to time a wave made a determined effort to swamp him. There was little danger of this happening, for he fitted the hatch so closely that he was quite an effective plug.
Fifty feet away, a long slate-colored mound, like an overturned boat, was rolling on the surface. Don looked at it thoughtfully and did some mental calculations. A brute this size should be valuable; with any luck there was a chance of a double bonus. In a few minutes he’d radio his report, but for the moment it was pleasant to drink the fresh Atlantic air and to feel the open sky above his head.
A gray thunderbolt shot up out of the depths and smashed back onto the surface of the water, smothering Don with spray. It was just Benj’s modest way of drawing attention to himself; a moment later the porpoise had swum up to the conning tower, so that Don could reach down and tickle its head. The great, intelligent eyes stared back into his; was it pure imagination, or did an almost human sense of fun also lurk in their depths?
Susan, as usual, circled shyly at a distance until jealousy overpowered her and she butted Benj out of the way. Don distributed caresses impartially and apologized because he had nothing to give them. He undertook to make up for the omission as soon as he returned to the Herman Melville.
“I’ll go for another swim with you, too,” he promised, “as long as you behave yourselves next time.” He rubbed thoughtfully at a large bruise caused by Benj’s playfulness, and wondered if he was not getting a little too old for rough games like this.
“Time to go home,” Don said firmly, sliding down into the cabin and slamming the hatch. He suddenly realized that he was very hungry, and had better do something about the breakfast he had missed. There were not many men on earth who had earned a better right to eat their morning meal. He had saved for humanity more tons of meat, oil and milk than could easily be estimated.
Don Burley was the happy warrior, coming home from one battle that man would always have to fight. He was holding at bay the specter of famine which had confronted all earlier ages, but which would never threaten the world again while the great plankton farms harvested their millions of tons of protein, and the whale herds obeyed their new masters. Man had come back to the sea after aeons of exile; until the oceans froze, he would never be hungry again . . .
Don glanced at the scanner as he set his course. He smiled as he saw the two echoes keeping pace with the central splash of light that marked his vessel. “Hang around,” he said. “We mammals must stick together.” Then, as the autopilot took over, he lay back in his chair.
And presently Benj and Susan heard a most peculiar noise, rising and falling against the drone of the turbines. It had filtered faintly through the thick walls of Sub 5, and only the sensitive ears of the porpoises could have detected it. But intelligent beasts though they were, they could hardly be expected to understand why Don Burley was announcing, in a highly unmusical voice, that he was Heading for the Last Round-up . . .
If I Forget Thee Oh Earth
Introduction
This story, which has been rather widely reprinted, was written at Christmas, 1951.
On another Christmas, seventeen years later, the crew of Apollo 8 became the first of all mankind to see an Earthrise from the Moon.
Let us hope that no one ever views an Earthrise like the child in this cautionary tale.
When Marvin was ten years old, his father took him through the long, echoing corridors that led up through Administration and Power, until at last they came to the uppermost levels of all and were among the swiftly growing vegetation of the Farmlands. Marvin liked it here: it was fun watching the great, slender plants creeping with almost visible eagerness towards the sunlight as it filtered down through the plastic domes to meet them. The smell of life was everywhere, awakening inexpressible longings in his heart: no longer was he breathing the dry, cool air of the residential levels, purged of all smells but the faint tang of ozone. He wished he could stay here for a little while, but Father would not let him. They went onwards until they had reached the entrance to the Observatory, which he had never visited: but they did not stop, and Marvin knew with a sense of rising excitement that there could be only one goal left. For the first time in his life, he was going Outside.
There were a dozen of the surface vehicles, with their wide balloon tyres and pressurized cabins, in the great servicing chamber. His father must have been expected, for they were led at once to the little scout car waiting by the huge circular door of the airlock. Tense with expectancy, Marvin settled himself down in the cramped cabin while his father started the motor and checked the controls. The inner door of the lock slid open and then closed behind them: he heard the roar of the great air-pumps fade slowly away as the pressure dropped to zero. Then the “Vacuum” sign flashed on, the outer door parted, and before Marvin lay the land which he had never yet entered.
He had seen it in photographs, of course: he had watched it imaged on television screens a hundred times. But now it was lying all around him, burning beneath the fierce sun that crawled so slowly across the jet-black sky. He stared
into the west, away from the blinding splendour of the sun—and there were the stars, as he had been told but had never quite believed. He gazed at them for a long time, marvelling that anything could be so bright and yet so tiny. They were intense unscintillating points, and suddenly he remembered a rhyme he had once read in one of his father’s books:
Twinkle, twinkle, little star,
How I wonder what you are.
Well, he knew what the stars were. Whoever asked that question must have been very stupid. And what did they mean by “twinkle”? You could see at a glance that all the stars shone with the same steady, unwavering light. He abandoned the puzzle and turned his attention to the landscape around him.
They were racing across a level plain at almost a hundred miles an hour, the great balloon tyres sending up little spurts of dust behind them. There was no sign of the Colony: in the few minutes while he had been gazing at the stars, its domes and radio towers had fallen below the horizon. Yet there were other indications of man’s presence, for about a mile ahead Marvin could see the curiously shaped structures clustering round the head of a mine. Now and then a puff of vapour would emerge from a squat smoke-stack and would instantly disperse.
They were past the mine in a moment: Father was driving with a reckless and exhilarating skill as if—it was a strange thought to come into a child’s mind—he was trying to escape from something. In a few minutes they had reached the edge of the plateau on which the Colony had been built. The ground fell sharply away beneath them in a dizzying slope whose lower stretches were lost in shadow. Ahead, as far as the eye could reach, was a jumbled wasteland of craters, mountain ranges, and ravines. The crests of the mountains, catching the low sun, burned like islands of fire in a sea of darkness: and above them the stars still shone as steadfastly as ever.
There could be no way forward—yet there was. Marvin clenched his fists as the car edged over the slope and started the long descent. Then he saw the barely visible track leading down the mountainside, and relaxed a little. Other men, it seemed, had gone this way before.
Night fell with a shocking abruptness as they crossed the shadow line and the sun dropped below the crest of the plateau. The twin searchlights sprang into life, casting blue-white bands on the rocks ahead, so that there was scarcely need to check their speed. For hours they drove through valleys and past the feet of mountains whose peaks seemed to comb the stars, and sometimes they emerged for a moment into the sunlight as they climbed over higher ground.
And now on the right was a wrinkled, dusty plain, and on the left, its ramparts and terraces rising mile after mile into the sky, was a wall of mountains that marched into the distance until its peaks sank from sight below the rim of the world. There was no sign that men had ever explored this land, but once they passed the skeleton of a crashed rocket, and beside it a stone cairn surmounted by a metal cross.
It seemed to Marvin that the mountains stretched on forever: but at last, many hours later, the range ended in a towering, precipitous headland that rose steeply from a cluster of little hills. They drove down into a shallow valley that curved in a great arc towards the far side of the mountains: and as they did so, Marvin slowly realized that something very strange was happening in the land ahead.
The sun was now low behind the hills on the right: the valley before them should be in total darkness. Yet it was awash with a cold white radiance that came spilling over the crags beneath which they were driving. Then, suddenly, they were out in the open plain, and the source of the light lay before them in all its glory.
It was very quiet in the little cabin now that the motors had stopped. The only sound was the faint whisper of the oxygen feed and an occasional metallic crepitation as the outer walls of the vehicle radiated away their heat. For no warmth at all came from the great silver crescent that floated low above the far horizon and flooded all this land with pearly light. It was so brilliant that minutes passed before Marvin could accept its challenge and look steadfastly into its glare, but at last he could discern the outlines of continents, the hazy border of the atmosphere, and the white islands of cloud. And even at this distance, he could see the glitter of sunlight on the polar ice.
It was beautiful, and it called to his heart across the abyss of space. There in that shining crescent were all the wonders that he had never known—the hues of sunset skies, the moaning of the sea on pebbled shores, the patter of falling rain, the unhurried benison of snow. These and a thousand others should have been his rightful heritage, but he knew them only from the books and ancient records, and the thought filled him with the anguish of exile.
Why could they not return? It seemed so peaceful beneath those lines of marching cloud. Then Marvin, his eyes no longer blinded by the glare, saw that the portion of the disk that should have been in darkness was gleaming faintly with an evil phosphorescence: and he remembered. He was looking upon the funeral pyre of a world—upon the radioactive aftermath of Armageddon. Across a quarter of a million miles of space, the glow of dying atoms was still visible, a perennial reminder of the ruinous past. It would be centuries yet before that deadly glow died from the rocks and life could return again to fill that silent, empty world.
And now Father began to speak, telling Marvin the story which until this moment had meant no more to him than the fairy-tales he had heard in childhood. There were many things he could not understand; it was impossible for him to picture the glowing, multi-coloured pattern of life on the planet he had never seen. Nor could he comprehend the forces that had destroyed it in the end, leaving the Colony, preserved by its isolation, as the sole survivor. Yet he could share the agony of those final days, when the Colony had learned at last that never again would the supply ships come flaming down through the stars with gifts from home. One by one the radio stations had ceased to call: on the shadowed globe the lights of the cities had dimmed and died, and they were alone at last, as no men had ever been alone before, carrying in their hands the future of the race.
Then had followed the years of despair, and the long-drawn battle for survival in this fierce and hostile world. That battle had been won, though barely: this little oasis of life was safe against the worst that Nature could do. But unless there was a goal, a future towards which it could work, the Colony would lose the will to live and neither machines nor skill nor science could save it then.
So, at last, Marvin understood the purpose of this pilgrimage. He would never walk beside the rivers of that lost and legendary world, or listen to the thunder raging above its softly rounded hills. Yet one day—how far ahead?—his children would return to claim their heritage. The winds and the rains would scour the poisons from the burning lands and carry them to the sea, and in the depths of the sea they would waste their venom until they could harm no living things. Then the great ships that were still waiting here on the silent, dusty plains could lift once more into space along the road that led to home.
That was the dream: and one day, Marvin knew with a sudden flash of insight, he would pass it on to his own son here at this same spot with the mountains behind him and the silver light from the sky streaming into his face.
He did not look back as they began the homeward journey. He could not bear to see the cold glory of the crescent Earth fade from the rocks around him, as he went to rejoin his people in their long exile.
The Cruel Sky
Introduction
I care not if you bridge the seas,
Or ride secure the cruel sky,
Or build consummate palaces
Of metal or of masonry. . . .
James Elroy Flecker: To a Poet a Thousand Years Hence. .
This story was written in 1966, presumably when I was moonlighting from 2001—which largely dominated my life from 1964 until 1968. I have just re-read it with rather mixed feelings, because I now have a considerable sense of identification with my “Dr. Elwin.”
Moreover, the phrase “one of the world’s most famous scientists—and certainly the world’s most
famous cripple” applies perfectly to Dr. Stephen Hawking—whose work also lies in the field of gravitation. In July, 1988, I spent three hours in a London TV studio with Dr. Hawking (and, via satellite, Dr. Sagan). For me, the encounter was an emotional as well as an intellectual experience, since I had recently been told I shared Dr. Hawking’s incurable disability (ALS, better known in the US as ‘Lou Gehrig’s Disease’), and therefore could not expect to see much of the 1990’s. Fortunately (see the Afterword to “On Golden Seas”) the diagnosis is now somewhat less ominous—but I have a more than casual interest in motorised wheel chairs. Better still, if only someone would invent it, the “Levvie” described in this story. Even before I found locomotion troublesome, I envied Dune’s floating Big Bad Baron.
Do not take my attack on the General Theory of Relativity too seriously; but I wish that writers who flaunt the Principle of Equivalence would make it clear that it’s true only for vanishingly small volumes of space.
I now feel somewhat guilty at eliminating one of the world’s rarest and most beautiful animals. Perhaps it should have been a Yeti after all; they may be equally rare, but by general concensus they’re certainly not beautiful.
By midnight, the summit of Everest was only a hundred yards away, a pyramid of snow, pale and ghostly in the light of the rising Moon. The sky was cloudless, and the wind that had been blowing for days had dropped almost to zero. It must be rare indeed for the highest point on Earth to be so calm and peaceful; they had chosen their time well.
Perhaps too well, thought George Harper; it had been almost disappointingly easy. Their only real problem had been getting out of the hotel without being observed. The management objected to unauthorized midnight excursions up the mountain; there could be accidents, which were bad for business.
