The Deep Range

by Arthur C. Clarke

  Commander Henson, the Marine Division’s master diver, was waiting in the plane with the equipment. There was another brief argument before the commander capitulated with good grace and, Franklin thought, a certain amount of relief. If anyone else was to attempt this mission, there was no doubt that Henson, with his unparalleled experience, was the obvious choice. Franklin even hesitated for a moment, wondering if by stubbornly insisting on going himself, he might not be reducing the chances of success. But he had been on the bottom and knew exactly what conditions were down there; it would waste precious time if Henson went down in the sub to make a reconnaissance.

  Franklin swallowed his pH pills, took his injections, and climbed into the flexible rubber suit which would protect him from the near-zero temperature on the sea bed. He hated suits—they interfered with movement and upset one’s buoyancy—but this was a case where he had no choice. The complex breathing unit, with its three cylinders—one the ominous red of compressed hydrogen—was strapped to his back, and he was lowered into the sea.

  Commander Henson swam around him for five minutes while all the fittings were checked, the weight belt was adjusted, and the sonar transmitter tested. He was breathing easily enough on normal air, and would not switch over to the oxyhydrogen mixture until he had reached a depth of three hundred feet. The change-over was automatic, and the demand regulator also adjusted the oxygen flow so that the mixture ratio was correct at any depth. As correct as it could be, that is, for a region in which man was never intended to live.…

  At last everything was ready. The explosive charges were securely attached to his belt, and he gripped the handrail around the tiny conning tower of the sub. “Take her down,” he said to the pilot. “Fifty feet a minute, and keep your forward speed below two knots.”

  “Fifty feet a minute it is. If we pick up speed, I’ll kill it with the reverse jets.”

  Almost at once, daylight faded to a gloomy and depressing green. The water here on the surface was almost opaque, owing to the debris thrown up by the oil well. Franklin could not even see the width of the conning tower; less than two feet from his eyes the metal rail blurred and faded into nothingness. He was not worried; if necessary, he could work by touch alone, but he knew that the water was much clearer on the bottom.

  Only thirty feet down, he had to stop the descent for almost a minute while he cleared his ears. He blew and swallowed frantically before the comforting “click” inside his head told him that all was well; how humiliating it would have been, he thought, had he been forced back to the surface because of a blocked Eustachian tube! No one would have blamed him, of course; even a mild cold could completely incapacitate the best diver—but the anticlimax would have been hard to live down.

  The light was fading swiftly as the sun’s rays lost their battle with the turbid water. A hundred feet down, he seemed to be in a world of misty moonlight, a world completely lacking color or warmth. His ears were giving him no trouble now, and he was breathing without effort, but he felt a subtle depression creeping over him. It was, he was sure, only an effect of the failing light—not a premonition of the thousand feet of descent that still lay ahead of him.

  To occupy his mind, he called the pilot and asked for a progress report. Fifty drums had now been attached to the derrick, giving a total lift of well over a hundred tons. Six of the passengers in the trapped sub had become unconscious but appeared to be in no danger; the remaining seventeen were uncomfortable, but had adapted themselves to the increased pressure. The leak was getting no worse, but there were now three inches of water in the control room, and before long there would be danger of short circuits.

  “Three hundred feet down,” said Commander Henson’s voice. “Check your hydrogen-flow meter—you should be starting the switch-over now.”

  Franklin glanced down at the compact little instrument panel. Yes, the automatic change-over was taking place. He could detect no difference in the air he was breathing, but in the next few hundred feet of descent most of the dangerous nitrogen would be flushed out. It seemed strange to replace it with hydrogen, a far more reactive—and even explosive—gas, but hydrogen produced no narcotic effects and was not trapped in the body tissues as readily as nitrogen.

  It seemed to have grown no darker in the last hundred feet; his eyes had accustomed themselves to the low level of illumination, and the water was slightly clearer. He could now see for two or three yards along the smooth hull he was riding down into the depths where only a handful of unprotected men had ever ventured—and fewer still returned to tell the story.

  Commander Henson called him again. “You should be on fifty per cent hydrogen now. Can you taste it?”

  “Yes—a metallic sort of flavor. Not unpleasant, though.”

  “Talk as slowly as you can,” said the commander. “It’s hard to understand you—your voice sounds so high-pitched now. Are you feeling quite O.K.?”

  “Yes,” replied Franklin, glancing at his depth gauge. “Will you increase my rate of descent to a hundred feet a minute? We’ve no time to waste.”

  At once he felt the vessel sinking more swiftly beneath him as the ballast tanks were flooded, and for the first time he began to feel the pressure around him as something palpable. He was going down so quickly that there was a slight lag as the insulating layer of air in his suit adjusted to the pressure change; his arms and legs seemed to be gripped as if by a huge and gentle vice, which slowed his movements without actually restricting them.

  The light had now nearly gone, and as if in anticipation of his order the pilot of the sub switched on his twin searchlights. There was nothing for them to illumine, here in this empty void midway between sea bed and sky, but it was reassuring to see the double nimbus of scattered radiance floating in the water ahead of him. The violet filters had been removed, for his benefit, and now that his eyes had something distant to focus upon he no longer felt so oppressively shut in and confined.

  Eight hundred feet down—more than three quarters of the way to the bottom. “Better level off here for three minutes,” advised Commander Henson. “I’d like to keep you here for half an hour, but we’ll have to make it up on the way back.”

  Franklin submitted to the delay with what grace he could. It seemed incredibly long; perhaps his time sense had been distorted, so that what was really a minute appeared like ten. He was going to ask Commander Henson if his watch had stopped when he suddenly remembered that he had a perfectly good one of his own. The fact that he had forgotten something so obvious was, he realized, rather a bad sign; it suggested that he was becoming stupid. However, if he was intelligent enough to know that he was becoming stupid things could not be too bad. … Luckily the descent started again before he could get too involved in this line of argument.

  And now he could hear, growing louder and louder each minute, the incessant roar of the great geyser of gas belching from the shaft which inquisitive and interfering man had drilled in the ocean bed. It shook the sea around him, already making it hard to hear the advice and comments of his helpers. There was a danger here as great as that of pressure itself; it the gas jet caught him, he might be tossed hundreds of feet upward in a matter of seconds and would explode like a deep-sea fish dragged suddenly to the surface.

  “We’re nearly there,” said the pilot, after they had been sinking for what seemed an age. “You should be able to see the derrick in a minute; I’ll switch on the lower lights.”

  Franklin swung himself over the edge of the now slowly moving sub and peered down the misty columns at light. At first he could see nothing; then, at an indeterminate distance, he made out mysterious rectangles and circles. They baffled him for a moment before he realized that he was seeing the air-filled drums which were now straining to lift the shattered derrick.

  Almost at once he was able to make out the framework of twisted girders below them, and presently a brilliant star—fantastically out of place in this dreary underworld—burst into life just outside the cone of his searchlights.
He was watching one of the cutting torches at work, manipulated by the mechanical hands of a sub just beyond visual range.

  With great care, his own vessel positioned him beside the derrick, and for the first time he realized how hopeless his task would have been had he been compelled to rely on touch to find his way around. He could see the two girders to which he had to attach his charge; they were hemmed in by a maze of smaller rods, beams, and cables through which he must somehow make his way.

  Franklin released his hold on the sub which had towed him so effortlessly into the depths, and with slow, easy strokes swam toward the derrick. As he approached, he saw for the first time the looming mass of the trapped sub, and his heart sank as he thought of all the problems that must still be solved before it could be extricated. On a sudden impulse, he swam toward the helpless vessel and banged sharply on the hull with the pair of wire cutters from his little tool kit. The men inside knew that he was here, of course, but the signal would have an altogether disproportionate effect on their morale.

  Then he started work. Trying to ignore the throbbing vibration which filled all the water around him and made it difficult to think, he began a careful survey of the metal maze into which he must swim.

  It would not be difficult to reach the nearest girder and place the charge. There was an open space between three I beams, blocked only by a loop of cable which could be easily pushed out of the way (but he’d have to watch that it didn’t tangle in his equipment when he swam past it). Then the girder would be dead ahead of him; what was more, there was room to turn around, so that he could avoid the unpleasant necessity of creeping out backward.

  He checked again, and could see no snags. To make doubly sure, he talked it over with Commander Henson, who could see the situation almost as well on the TV screen of the sub. Then he swam slowly into the derrick, working his way along the metal framework with his gloved hands. He was quite surprised to find that, even at this depth, there was no shortage of the barnacles and other marine growths which always make it dangerous to touch any object which had been underwater for more than a few months.

  The steel structure was vibrating like a giant tuning fork; he could feel the roaring power of the uncapped well both through the sea surrounding him and through the metal beneath his hands. He seemed to be imprisoned in an enormous, throbbing cage; the sheer noise, as well as the awful pressure, was beginning to make him dull and lethargic It now needed a positive effort of will to take any action; he had to keep reminding himself that many lives besides his own depended upon what he was doing.

  He reached the girder and slowly taped the flat package against the metal. It took a long time to do it to his satisfaction, but at last the explosive was in place and he felt sure that the vibration would not dislodge it. Then he looked around for his second objective—the girder forming the other edge of the derrick.

  He had stirred up a good deal of dirt and could no longer see so clearly, but it seemed to Franklin that there was nothing to stop him crossing the interior of the derrick and completing the job. The alternative was to go back the way he had come, and then swim right around to the other side of the wreckage. In normal circumstances that would have been easy enough—but now every movement had to be considered with care, every expenditure of effort made grudgingly only after its need had been established beyond all doubt.

  With infinite caution, he began to move through the throbbing mist. The glare of the searchlights, pouring down upon him, was so dazzling that it pained his eyes. It never occurred to him that he had only to speak into his microphone and the illumination would be reduced instantly to whatever level he wished. Instead, he tried to keep in whatever shadow he could find among the confused pile of wreckage through which he was moving.

  He reached the girder, and crouched over it for a long time while he tried to remember what he was supposed to be doing here. It took Commander Henson’s voice, shouting in his ears like some far-off echo, to call him back to reality. Very carefully and slowly he taped the precious slab into position; then he floated beside it, admiring his meaningless handiwork, while the annoying voice in his ear grew ever more insistent. He could stop it, he realized, by throwing away his face mask and the irritating little speaker it contained. For a moment he toyed with this idea, but discovered that he was not strong enough to undo the straps holding the mask in place. It was too bad; perhaps the voice would shut up if he did what it told him to.

  Unfortunately, he had no idea which was the right way out of the maze in which he was now comfortably ensconced. The light and noise were very confusing; when he moved in any direction, he sooner or later banged into something and had to turn back. This annoyed but did not alarm him, for he was quite happy where he was.

  But the voice would not give him any peace. It was no longer at all friendly and helpful; he dimly realized that it was being downright rude, and was ordering him about in a manner in which—though he could not remember why—people did not usually speak to him. He was being given careful and detailed instructions which were repeated over and over again, with increasing emphasis, until he sluggishly obeyed them. He was too tired to answer back, but he wept a little at the indignity to which he was being subjected. He had never been called such things in his life, and it was very seldom indeed that he had heard such shocking language as was now coming through his speaker. Who on earth would yell at him this way? “Not that way, you goddammed fool, sir! To the left—LEFT! That’s fine—now forward a bit more—don’t stop there! Christ, he’s gone to sleep again. WAKE UP—SNAP OUT OF IT OR I’LL KNOCK YOUR BLOODY BLOCK OFF! That’s a good boy—you’re nearly there—just another couple of feet …” and so on endlessly, and some of it with very much worse language than that.

  Then, quite to his surprise, there was no longer twisted metal around him. He was swimming slowly in the open, but he was not swimming for long. Metal fingers closed upon him, none too gently, and he was lifted into the roaring night.

  From far away he heard four short, muffled explosions, and something deep down in his mind told him that for two of these he was responsible. But he saw nothing of the swift drama a hundred feet below as the radio fuses detonated and the great derrick snapped in two. The section lying across the trapped submarine was still too heavy to be lifted clear by the buoyancy tanks, but now that it was free to move it teetered for a moment like a giant seesaw, then slipped aside and crashed on to the sea bed.

  The big sub, all restraint removed, began to move upward with increasing speed; Franklin felt the wash of its close passage, but was too bemused to realize what it meant. He was still struggling back into hazy consciousness; around eight hundred feet, quite abruptly, he started to react to Henson’s bullying ministrations, and, to the commander’s vast relief, began to answer him back in kind. He cursed wildly for about a hundred feet, then became fully aware of his surroundings and ground to an embarrassed halt. Only then did he realize that his mission had been successful and that the men he had set out to rescue were already far above him on their way back to the surface.

  Franklin could make no such speed. A decompression chamber was waiting for him at the three-hundred-foot level, and in its cramped confines he was to fly back to Brisbane and spend eighteen tedious hours before all the absorbed gas had escaped from his body. And by the time the doctors let him out of their clutches, it was far too late to suppress the tape recording that had circulated throughout the entire bureau. He was a hero to the whole world, but if he ever grew conceited he need only remind himself that all his staff had listened gleefully to every word of Commander Henson’s fluently profane cajoling of their director.

  CHAPTER XXV

  PETER NEVER LOOKED back as he walked up the gangplank into the projectile from which, in little more than half an hour, he would have his first view of the receding Earth. Franklin could understand why his son kept his head averted; young men of eighteen do not cry in public. Nor, for that matter, he told himself fiercely, do middle-aged directors of imp
ortant bureaus.

  Anne had no such inhibitions; she was weeping steadily despite all that Indra could do to comfort her. Not until the doors of the spaceship had finally sealed and the thirty-minute warning siren had drowned all other noises did she subside into an intermittent sniffling.

  The tide of spectators, of friends and relatives, of cameramen and Space Department officials, began to retreat before the moving barriers. Clasping hands with his wife and daughter, Franklin let himself be swept along with the flood of humanity. What hopes and fears, sorrows and joys surrounded him now! He tried to remember his emotions at his first takeoff; it must have been one of the great moments of his life—yet all recollection of it had gone, obliterated by thirty years of later experience.

  And now Peter was setting out on the road his father had traveled half a lifetime before. May you have better luck among the stars than I did. Franklin prayed. He wished he could be there at Port Lowell when Irene greeted the boy who might have been her son, and wondered how Roy and Rupert would receive their half-brother. He was sure that they would be glad to meet him; Peter would not be as lonely on Mars as Ensign Walter Franklin had once been.

  They waited in silence while the long minutes wore away. By this time, Peter would be so interested in the strange and exciting world that was to be his home for the next week that he would already have forgotten the pain of parting. He could not be blamed if his eyes were fixed on the new life which lay before him in all its unknown promise.

  And what of his own life? Franklin asked himself. Now that he had launched his son into the future, could he say that he had been a success? It was a question he found very hard to answer honestly. So many things that he had attempted had ended in failure or even in disaster. He knew now that he was unlikely to rise any farther in the service of the state; he might be a hero, but he had upset too many people when he became the surprised and somewhat reluctant ally of the Maha Thero. Certainly he had no hope of promotion—nor did he desire it—during the five or ten years which would be needed to complete the reorganization of the Bureau of Whales. He had been told in as many words that since he was partly responsible for the situation—the mess, it was generally called—he could sort it out himself.
