Expedition to Earth (Arthur C. Clarke Collection: Short Stories)

by Arthur C. Clarke

  Still the same superb orator, he paused for effect, noting with satisfaction the ripple of interest, the sudden alertness on the tired faces of his listeners.

  “My secret is safe enough with you,” he continued, “for the enemy will never find this place. The entrance is already blocked by many hundreds of feet of rock.”

  Still there was no movement. Only the Director of Propaganda turned suddenly white, and swiftly recovered—but not swiftly enough to escape the Master’s eye. The Master smiled inwardly at this belated confirmation of an old doubt. It mattered little now; true and false, they would all die together.

  All but one.

  “Two years ago,” he went on, “when we lost the battle of Antarctica, I knew that we could no longer be certain of victory. So I made my preparations for this day. The enemy has already sworn to kill me. I could not remain in hiding anywhere on the Earth, still less hope to rebuild our fortunes.

  “But there is another way, though a desperate one.

  “Five years ago, one of our scientists perfected the technique of suspended animation. He found that by relatively simple means all life processes could be arrested for an indefinite time. I am going to use this discovery to escape from the present into a future which will have forgotten me. There I can begin the struggle again, with the help of certain devices that might yet have won this war had we been granted more time.

  “Good-bye, gentlemen. And once again, my thanks for your help and my regrets at your ill fortune.”

  He saluted, turned on his heel, and was gone. The metal door thudded decisively behind him. There was a frozen silence; then the Director of Propaganda rushed to the exit, only to recoil with a startled cry. The steel door was already too hot to touch. It had been welded immovably into the wall.

  The Minister for War was the first to draw his automatic.

  The Master was in no great hurry now. On leaving the council room he had thrown the secret switch of the welding circuit. The same action had opened a panel in the wall of the corridor, revealing a small circular passage sloping steadily upward. He began to walk slowly along it.

  Every few hundred feet the tunnel angled sharply, though still continuing the upward climb. At each turning the Master stopped to throw a switch, and there was the thunder of falling rock as a section of corridor collapsed.

  Five times the passageway changed its course before it ended in a spherical, metal-walled room. Multiple doors closed softly on rubber seatings, and the last section of tunnel crashed behind. The Master would not be disturbed by his enemies, nor by his friends.

  He looked swiftly around the room to satisfy himself that all was ready. Then he walked to a simple control board and threw, one after another, a set of tiny switches. They had to carry little current—but they had been built to last. So had everything in that strange room. Even the walls were made of metals far less ephemeral than steel.

  Pumps started to whine, drawing the air from the chamber and replacing it with sterile nitrogen. Moving more swiftly now, the Master went to the padded couch and lay down. He thought he could feel himself bathed by the bacteria-destroying rays from the lamps above his head, but that of course was fancy. From a recess beneath the couch he drew a hypodermic and injected a milky fluid into his arm.

  Then he relaxed and waited.

  It was already very cold. Soon the refrigerators would bring the temperature down far below freezing, and would hold it there for many hours. Then it would rise to normal, but by that time the process would be completed, all bacteria would be dead and the Master could sleep, unchanged, forever.

  He had planned to wait a hundred years. More than that he dared not delay, for when he awoke he would have to master all the changes in science and society that the passing years had wrought. Even a century might have altered the face of a civilization beyond his understanding, but that was a risk he would have to take. Less than a century would not be safe, for the world would still be full of bitter memories.

  Sealed in a vacuum beneath the couch were the electronic counters operated by thermocouples hundreds of feet above, on the eastern face of the mountain where no snow could ever cling. Every day the rising sun would operate them and the counters would add one unit to their store. So the coming of dawn would be noted in the darkness where the Master slept.

  When any one of the counters reached the total of thirty-six thousand, a switch would close and oxygen would flow back into the chamber. The temperature would rise, and the automatic hypodermic strapped to the Master’s arm would inject the calculated amount of fluid. He would awaken. Then he would press the button which would blast away the mountainside and give him free passage to the outer world.

  Everything had been considered. There could be no failure. All the machinery had been triplicated and was as perfect as science could contrive.

  The Master’s last thought as consciousness ebbed was not of his past life, nor of the mother whose hopes he had betrayed. Unbidden and unwelcome, there came into his mind the words of an ancient poet:

  To sleep, perchance to dream…

  No, he would not, he dared not dream. He would only sleep… sleep… sleep…

  Twenty miles away, the battle was coming to its end. Not a dozen of the Master’s ships were left, fighting hopelessly against overwhelming fire. The action would have ended long ago had the attackers not been ordered to risk no ships in unnecessary adventures. The decision was to be left to the long-range artillery. So the great destroyers, the airborne battleships of this age, lay with their fighter screens in the shelter of the mountains, pouring salvo after salvo into the doomed formations.

  Aboard the flagship, a young Hindu gunnery officer set vernier dials with infinite care and gently pressed a pedal with his foot. There was the faintest of shocks as the dirigible torpedoes left their cradles and hurled themselves at the enemy. The young Indian sat waiting tensely as the chronometer ticked off the seconds. This, he thought, was probably the last salvo he would ever fire. Somehow he felt none of the elation he had expected; indeed, he was surprised to discover a kind of impersonal sympathy for his doomed opponents, whose lives were now ebbing with every passing second.

  Far away a sphere of violet fire blossomed above the mountains, among the darting specks that were enemy ships. The gunner leaned forward tensely and counted. One-two-three-four-five times came that peculiar explosion. Then the sky cleared. The struggling specks were gone.

  In his log, the gunner noted briefly: “0124 hrs. Salvo No. 12 fired. Five torps exploded among enemy ships, which were destroyed. One torp failed to detonate.”

  He signed the entry with a flourish and laid down his pen. For a while he sat staring at the log’s familiar brown cover, with the cigarette burns at the edges and the inevitable stained rings where cups and glasses had been carelessly set down. Idly he thumbed through the leaves, noting once again the handwriting of his many predecessors. And as he had done so often before, he turned to a familiar page where a man who had once been his friend had begun to sign his name but had never lived to complete it.

  With a sigh, he closed the book and locked it away. The war was over.

  Far away among the mountains, the torpedo that had failed to explode was still gaining speed under the drive of its rockets. Now it was a scarcely visible line of light, racing between the walls of a lonely valley. Already the snows that had been disturbed by the scream of its passage were beginning to rumble down the mountain slopes.

  There was no escape from the valley: it was blocked by a sheer wall a thousand feet high. Here the torpedo that had missed its mark found a greater one. The Master’s tomb was too deep in the mountain even to be shaken by the explosion but the hundreds of tons of falling rock swept away three tiny instruments and their connections, and a future that might have been went with them into oblivion.

  The first rays of the rising sun would still fall on the shattered face of the mountain, but the counters that were waiting for the thirty-six thousandth dawn would still
be waiting when dawns and sunsets were no more.

  In the silence of the tomb that was not quite a tomb, the Master knew nothing of this. And he slumbered on, until the century was far behind—very far indeed.

  After what by some standards would have been a little while, the earth’s crust decided it had borne the weight of The Himalayas for long enough. Slowly the mountains dropped, tilting the southern plains of India toward the sky. And presently the plateau of Ceylon was the highest point on the surface of the globe, and the ocean about Everest was five and a half miles deep. Yet the Master’s slumber was still dreamless and undisturbed.

  Slowly, patiently, the silt drifted down through the towering ocean heights onto the wreck of The Himalayas. The blanket that would one day be chalk began to thicken at the rate of an inch or two every century. If one had returned some time later, one might have found that the sea bed was no longer five miles down, or even four, or three. Then the land tilted again, and a mighty range of limestone mountains towered where once had been the oceans of Tibet. But the Master knew nothing of this, nor was his sleep troubled when it happened again and again and yet again.

  Now the rain and the rivers were washing away the chalk and carrying it out to the strange new oceans, and the surface was moving down toward the hidden tomb. Slowly the miles of rock were winnowed away until at last the sphere which housed the Master’s body returned to the light of day—though to a day much longer, and much dimmer, than it had been when the Master closed his eyes.

  Little did the Master dream of the races that had flowered and died since that early morning of the world when he went to his long sleep. Very far away was that morning now, and the shadows were lengthening to the east; the sun was dying and the world was very old. But still the children of Adam ruled its seas and skies, and filled with their tears and laughter the plains and the valleys and the woods that were older than the shifting hills.

  The Master’s dreamless sleep was more than half ended when Trevindor the Philosopher was born, between the fall of the Ninety-seventh Dynasty and the rise of the Fifth Galactic Empire. He was born on a world very far from Earth. Few were the men who now set foot on the ancient home of their race, so distant from the throbbing heart of the Universe.

  They brought Trevindor to Earth when his brief clash with the Empire had come to its inevitable end. Here he was tried by the men whose ideals he had challenged, and here it was that they pondered long over the manner of his necessary fate.

  The case was unique. The gentle, philosophic culture that now ruled the Galaxy had never before met with opposition, even on the level of pure intellect, and the polite but implacable conflict of wills had left it severely shaken. It was typical of the Council’s members that, when a decision had proved impossible, they had appealed to Trevindor himself for help.

  In the whitely gleaming Hall of Justice, that had not been entered for nigh on a million years, Trevindor stood proudly facing the men who had proved stronger than he. In silence he listened to their request; then he paused in reflection. His judges waited patiently until at last he spoke.

  “You suggest that I should promise not to defy you again,” he began, “but I shall make no promise that I may be unable to keep. Our views are too divergent and sooner or later we should clash again.

  “There was a time when your choice would have been easy. You could have exiled me, or put me to death. But today—where among all the worlds of the Universe is there one planet where you could hide me if I did not choose to stay? Remember, I have many disciples scattered the length and breadth of the Galaxy.

  “There remains the other alternative. I shall bear you no malice if you revive the ancient custom of execution to meet my case.”

  There was a murmur of annoyance from the Council, and the President replied sharply, his color heightening.

  “That remark is in questionable taste. We asked for serious suggestions, not reminders—even if intended humorously—of the barbaric customs of our remote ancestors.”

  Trevindor accepted the rebuke with a bow. “I was merely mentioning all the possibilities. There are two others that have occurred to me. It would be a simple matter to change my mind pattern to your way of thinking so that no future disagreement can arise.”

  “We have already considered that. We were forced to reject it, attractive though it is, for the destruction of your personality would be equivalent to murder. There are only fifteen more powerful intellects than yours in the Universe, and we have no right to tamper with it. And your final suggestion?”

  “Though you cannot exile me in space, there is still one alternative. The river of Time stretches ahead of us as far as our thoughts can go. Send me down that stream to an age when you are certain this civilization will have passed. That I know you can do with the aid of the Roston time-field.”

  There was a long pause. In silence the members of the Council were passing their decisions to the complex analysis machine which would weigh them one against the other and arrive at the verdict. At length the President spoke.

  “It is agreed. We will send you to an age when the sun is still warm enough for life to exist on the Earth, but so remote that any trace of our civilization is unlikely to survive. We will also provide you with everything necessary for your safety and reasonable comfort. You may leave us now. We will call for you again as soon as all arrangements have been made.”

  Trevindor bowed, and left the marble hall. No guards followed him. There was nowhere he could flee, even if he wished, in this Universe which the great Galactic liners could span in a single day.

  For the first and the last time, Trevindor stood on the shore of what had once been the Pacific, listening to the wind sighing through the leaves of what had once been palms. The few stars of the nearly empty region of space through which the sun was now passing shone with a steady light through the dry air of the aging world. Trevindor wondered bleakly if they would still be shining when he looked again upon the sky, in a future so distant that the sun itself would be sinking to its death.

  There was a tinkle from the tiny communicator band upon his wrist. So, the time had come. He turned his back upon the ocean and walked resolutely to meet his fate. Before he had gone a dozen steps, the time-field had seized him and his thoughts froze in an instant that would remain unchanged while the oceans shrank and vanished, the Galactic Empire passed away, and the great star clusters crumbled into nothingness.

  But, to Trevindor, no time elapsed at all. He only knew that at one step there had been moist sand beneath his feet, and at the next hard, baked rock. The palms had vanished, the murmur of the sea was stilled. It needed only a glance to show that even the memory of the sea had long since faded from this parched and dying world. To the far horizon, a great desert of red sandstone stretched unbroken and unrelieved by any growing thing. Overhead, the orange disk of a strangely altered sun glowered from a sky so black that many stars were clearly visible.

  Yet, it seemed, there was still life on this ancient world. To the north—if that were still the north—the somber light glinted upon some metallic structure. It was a few hundred yards away, and as Trevindor started to walk toward it he was conscious of a curious lightness, as if gravity itself had weakened.

  He had not gone far before he saw that he was approaching a low metal building which seemed to have been set down on the plain rather than constructed there, for it tilted slightly with the slope of the land. Trevindor wondered at his incredible good fortune at finding civilization so easily. Another dozen steps, and he realized that not chance but design had so conveniently placed this building here, and that it was as much a stranger to this world as he himself.

  There was no hope at all that anyone would come to meet him as he walked toward it.

  The metal plaque above the door added little to what he had already surmised. Still new and untarnished as if it had just been engraved—as indeed, in a sense, it had—the lettering brought a message at once of hope and of bitterness.


  To Trevindor, the greetings of the Council.

  This building, which we have sent after you through the time-field, will supply all your needs for an indefinite period.

  We do not know if civilization will still exist in the age in which you find yourself. Man may now be extinct, since the chromosome K Star K will have become dominant and the race may have mutated into something no longer human. That is for you to discover.

  You are now in the twilight of the Earth and it is our hope that you are not alone. But if it is your destiny to be the last living creature on this once lovely world, remember that the choice was yours. Farewell.

  Twice Trevindor read the message, recognizing with an ache the closing words which could only have been written by his friend, the poet Cintillarne. An overwhelming sense of loneliness and isolation came flooding into his soul. He sat down upon a shelf of rock and buried his face in his hands.

  A long time later, he arose to enter the building. He felt more than grateful to the long-dead Council which had treated him so chivalrously. The technical achievement of sending an entire building through time was one he had believed beyond the resources of his age. A sudden thought struck him and he glanced again at the engraved lettering, noticing for the first time the date it bore. It was five thousand years later than the time when he had faced his peers in the Hall of Justice.

  Fifty centuries had passed before his judges could redeem their promise to a man as good as dead. Whatever the faults of the Council, its integrity was of an order beyond the comprehension of an earlier age.

  Many days passed before Trevindor left the building again. Nothing had been overlooked: even his beloved thought records were there. He could continue to study the nature of reality and to construct philosophies until the end of the Universe, barren though that occupation would be if his were the only mind left on Earth. There was little danger, he thought wryly, that his speculations concerning the purpose of human existence would once again bring him into conflict with society.
