The Deep Range

by Arthur C. Clarke

  The sea had begun to shape his life and thought, as it must that of all men worthy to master it and learn its secrets. He felt a kinship with all the creatures that moved throughout its length and depth, even when they were enemies which it was his duty to destroy. But above all, he felt a sympathy and an almost mystical reverence, of which he was half ashamed, toward the great beasts whose destinies he ruled.

  He believed that most wardens knew that feeling, though they were careful to avoid admitting it in their shoptalk. The nearest they came to it was when they accused each other of being “whale happy”, a somewhat indefinable term which might be summed up as acting more like a whale than a man in a given situation. It was a form of identification without which no warden could be really good at his job, but there were times when it could become too extreme. The classic case—which everyone swore was perfectly true—was that of the senior warden who felt he was suffocating unless he brought his sub up to blow every ten minutes.

  Being regarded—and regarding themselves—as the elite of the world’s army of underwater experts, the wardens were always called upon when there was some unusual job that no one else cared to perform. Sometimes these jobs were so suicidal that it was necessary to explain to the would-be client that he must find another way out of his difficulties.

  But occasionally there was no other way, and risks had to be taken. The bureau still remembered how Chief Warden Kircher, back in ’22, had gone up the giant intake pipes through which the cooling water flowed into the fusion power plant supplying half the South American continent. One of the filter grilles had started to come loose, and could be fixed only by a man on the spot. With strong ropes tied around his body to prevent him from being sucked through the wire meshing, Kircher had descended into the roaring darkness. He had done the job and returned safely; but that was the last time he ever went under water.

  So far, all Franklin’s missions had been fairly conventional ones; he had had to face nothing as hair-raising as Kircher’s exploit, and was not sure how he would react if such an occasion arose. Of course, he could always turn down any assignment that involved abnormal risks; his contract was quite specific on that point. But the “suicide clause”, as it was sardonically called, was very much a dead letter. Any warden who invoked it, except under the most extreme circumstances, would incur no displeasure from his superiors, but he would thereafter find it very hard to live with his colleagues.

  Franklin’s first operation beyond the call of duty did not come his way for almost five years—five busy, crowded, yet in retrospect curiously uneventful, years. But when it came, it more than made up for the delay.

  CHAPTER XIV

  THE CHIEF ACCOUNTANT dropped his tables and charts on the desk, and peered triumphantly at his little audience over the rims of his antiquated spectacles.

  “So you see, gentlemen,” he said, “there’s no doubt about it. In this area here”—he stabbed at the map again—“sperm whale casualties have been abnormally high. It’s no longer a question of the usual random variations in the census numbers. During the migrations of the last five years, no less than nine plus or minus two whales have disappeared in this rather small area.

  “Now, as you are all aware, the sperm whale has no natural enemies, except for the orcas that occasionally attack small females with calves. But we are quite sure that no killer packs have broken into this area for several years, and at least three adult males have disappeared. In our opinion, that left only one possibility.

  “The sea bed here is slightly less than four thousand feet down, which means that a sperm whale can just reach it with a few minutes’ time for hunting on the bottom before it has to return for air. Now, ever since it was discovered that Physeter feeds almost exclusively on squids, naturalists have wondered whether a squid can ever win when a whale attacks it. The general opinion was that it couldn’t, because the whale is much larger and more powerful.

  “But we must remember that even today no one knows how big the giant squid does grow; the Biology Section tells me that tentacles of Bathyteutis Maximus have been found up to eighty feet long. Moreover, a squid would only have to keep a whale held down for a matter of a few minutes at this depth, and the animal would drown before it could get back to the surface. So a couple of years ago we formulated the theory that in this area there lives at least one abnormally large squid. We—ahem—christened him Percy.

  “Until last week, Percy was only a theory. Then, as you know, Whale S.87693 was found dead on the surface, badly mauled and with its body covered with the typical scars caused by squid claws and suckers. I would like you to look at this photograph.”

  He pulled a set of large glossy prints out of his brief case and passed them around. Each showed a small portion of a whale’s body which was mottled with white streaks and perfectly circular rings. A foot ruler lay incongruously in the middle of the picture to give an idea of the scale.

  “Those, gentlemen, are sucker marks. They go up to six inches in diameter. I think we can say that Percy is no longer a theory. The question is: What do we do about him? He is costing us at least twenty thousand dollars a year. I should welcome any suggestions.”

  There was a brief silence while the little group of officials looked thoughtfully at the photographs. Then the director said: “I’ve asked Mr. Franklin to come along and give his opinion. What do you say, Walter? Can you deal with Percy?”

  “If I can find him, yes. But the bottom’s pretty rugged down there, and it might be a long search. I couldn’t use a normal sub, of course—there’d be no safety margin at that depth, especially if Percy started putting on the squeeze. Incidentally, what size do you think he is?”

  The chief accountant, usually so glib with figures, hesitated for an appreciable instant before replying.

  “This isn’t my estimate,” he said apologetically, “but the biologists say he may be a hundred and fifty feet long.”

  There were some subdued whistles, but the director seemed unimpressed. Long ago he had learned the truth of the old cliché that there were bigger fish in the sea than ever came out if it. He knew also that, in a medium where gravity set no limit to size, a creature could continue to grow almost indefinitely as long as it could avoid death. And of all the inhabitants of the sea, the giant squid was perhaps the safest from attack. Even its one enemy, the sperm whale, could not reach it if it remained below the four-thousand-foot level.

  “There are dozens of ways we can kill Percy if we can locate him,” put in the chief biologist. “Explosives, poison, electrocution—any of them would do. But unless there’s no alternative, I think we should avoid killing. He must be one of the biggest animals alive on this planet, and it would be a crime to murder him.”

  “Please, Dr. Roberts!” protested the director. “May I remind you that this bureau is only concerned with food production—not with research or the conservation of any animals except whales. And I do think that murder is rather a strong term to apply to an overgrown mollusk.”

  Dr. Roberts seemed quite unabashed by the mild reprimand.

  “I agree, sir,” he said cheerfully, “that production is our main job, and that we must always keep economic factors in mind. At the same time, we’re continually co-operating with the Department of Scientific Research and this seems another case where we can work together to our mutual advantage. In fact, we might even make a profit in the long run.”

  “Go on,” said the director, a slight twinkle in his eye. He wondered what ingenious plan the scientists who were supposed to be working for him had cooked up with their opposite numbers in Research.

  “No giant squid has ever been captured alive, simply because we’ve never had the tools for the job. It would be an expensive operation, but if we are going to chase Percy anyway, the additonal cost should not be very great. So I suggest that we try to bring him back alive.”

  No one bothered to ask how. If Dr. Roberts said it could be done, that meant he had already worked out a plan of campaign.
The directors, as usual, bypassed the minor technical details involved in hauling up several tons of fighting squid from a depth of a mile, and went straight to the important point.

  “Will Research pay for any of this? And what will you do with Percy when you’ve caught him?”

  “Unofficially, Research will provide the additional equipment if we make the subs and pilots available. We’ll also need that floating dock we borrowed from Maintenance last year; it’s big enough to hold two whales, so it can certainly hold one squid. There’ll be some additional expenditure here—extra aeration plant for the water, electrified mesh to stop Percy climbing out, and so on. In fact, I suggest that we use the dock as a lab while we’re studying him.”

  “And after that?”

  “Why, we sell him.”

  “The demand for hundred-and-fifty-foot squids as household pets would seem to be rather small.”

  Like an actor throwing away his best line, Dr. Roberts casually produced his trump card.

  “If we can deliver Percy alive and in good condition, Marineland will pay fifty thousand dollars for him. That was Professor Milton’s first informal offer when I spoke to him this morning. I’ve no doubt that we can get more than that; I’ve even been wondering if we could arrange things on a royalty basis. After all, a giant squid would be the biggest attraction Marineland ever had.”

  “Research was bad enough,” grumbled the director. “Now it looks as if you’re trying to get us involved in the entertainment business. Still, as far as I’m concerned it sounds fairly plausible. If Accounts can convince me that the project is not too expensive, and if no other snags turn up, we’ll go ahead with it. That is, of course, if Mr. Franklin and his colleagues think it can be done. They’re the people who’ll have to do the work.”

  “If Dr. Roberts has any practical plan, I’ll be glad to discuss it with him. It’s certainly a very interesting project.”

  That, thought Franklin, was the understatement of the year. But he was not the sort of man who ever waxed too enthusiastic over any enterprise, having long ago decided that this always resulted in eventual disappointment. If “Operation Percy” came off, it would be the most exciting job he had ever had in his five years as a warden. But it was too good to be true; something would turn up to cancel the whole project.

  It did not. Less than a month later, he was dropping down to the sea bed in a specially modified deep-water scout. Two hundred feet behind him, Don Burley was following in a second machine. It was the first time they had worked together since those far-off days on Heron Island, but when Franklin had been asked to choose his partner he had automatically thought of Don. This was the chance of a lifetime, and Don would never forgive him if he selected anyone else.

  Franklin sometimes wondered if Don resented his own rapid rise in the service. Five years ago, Don had been a first warden; Franklin, a completely inexperienced trainee. Now they were both first wardens, and before long Franklin would probably be promoted again. He did not altogether welcome this, for, though he was ambitious enough, he knew that the higher he rose in the bureau the less time he would spend at sea. Perhaps Don knew what he was doing; it was very hard to picture him settling down in an office.…

  “Better try your lights,” said Don’s voice from the speaker. “Doc Roberts wants me to get a photograph of you.”

  “Right,” Franklin replied. “Here goes.”

  “My—you do look pretty! If I was another squid, I’m sure I’d find you irresistible. Swing broadside a minute. Thanks. Talk about a Christmas tree! It’s the first time I’ve ever seen one making ten knots at six hundred fathoms.”

  Franklin grinned and switched off the illuminations. This idea of Dr. Roberts’ was simple enough, but it remained to be seen if it would work. In the lightless abyss, many creatures carry constellations of luminous organs which they can switch on or off at will, and the giant squid, with its enormous eyes, is particularly sensitive to such lights. It uses them not only to lure its prey into its clutches, but also to attract its mates. If squids were as intelligent as they were supposed to be, thought Franklin, Percy would soon see through his disguise. It would be ironic, however, if a deep-diving sperm whale was deceived and he had an unwanted fight on his hands.

  The rocky bottom was now only five hundred feet below, every detail of it clearly traced on the short-range sonar scanner. It looked like an unpromising place for a search; there might be countless caves here in which Percy could hide beyond all hope of detection. On the other hand, the whales had detected him—to their cost. And anything that Physeter can do, Franklin, told himself, my sub can do just as well.

  “We’re in luck,” said Don. “The water’s as clear as I’ve ever seen it down here. As long as we don’t stir up any mud, we’ll be able to see a couple of hundred feet.”

  That was important; Franklin’s luminous lures would be useless if the water was too turbid for them to be visible. He switched on the external TV camera, and quickly located the faint glow of Don’s starboard light, two hundred feet away. Yes, this was extremely good luck; it should simplify their task enormously.

  Franklin tuned in to the nearest beacon and fixed his position with the utmost accuracy. To make doubly sure, he got Don to do the same, and they split the difference between them. Then, cruising slowly on parallel courses, they began their careful search of the sea bed.

  It was unusual to find bare rock at such a depth, for the ocean bed is normally covered with a layer of mud and sediment hundreds or even thousands of feet thick. There must, Franklin decided, be powerful currents scouring this area clear—but there was certainly no current now, as his drift meter assured him. It was probably seasonal, and associated with the ten-thousand-foot-deeper cleft of the Miller Canyon, only five miles away.

  Every few seconds, Franklin switched on his pattern of colored lights, then watched the screen eagerly to see if there was any response. Before long he had half a dozen fantastic deep-sea fish following him—nightmare creatures, two or three feet long, with enormous jaws and ridiculously attenuated feelers and tendrils trailing from their bodies. The lure of his lights apparently overcame their fear of his engine vibration, which was an encouraging sign. Though his speed quickly left them behind, they were continually replaced by new monsters, no two of which appeared to be exactly the same.

  Franklin paid relatively little attention to the TV screen; the longer-range senses of the sonar, warning him of what lay in the thousand feet ahead of him, were more important. Not only had he to keep a look out for his quarry, but he had to avoid rocks and hillocks which might suddenly rear up in the track of the sub. He was doing only ten knots, which was slow enough, but it required all his concentration. Sometimes he felt as if he was flying at treetop height over hilly country in a thick fog.

  They traveled five uneventful miles, then made a hairpin turn and came back on a parallel course. If they were doing nothing else, thought Franklin, at least they were producing a survey of this area in more detail than it had ever been mapped before. Both he and Don were operating with their recorders on, so that the profile of the sea bed beneath them was being automatically mapped.

  “Whoever said this was an exciting life?” said Don when they made their fourth turn. “I’ve not even seen a baby octopus. Maybe we’re scaring the squids away.”

  “Roberts said they’re not very sensitive to vibrations, so I don’t think that’s likely. And somehow I feel that Percy isn’t the sort who’s easily scared.”

  “If he exists,” said Don skeptically.

  “Don’t forget those six-inch sucker marks. What do you think made them—mice?”

  “Hey!” said Don. “Have a look at that echo on bearing 250, range 750 feet. Looks like a rock, but I thought it moved then.”

  Another false alarm, Franklin told himself. No—the echo did seem a bit fuzzy. By God, it was moving!

  “Cut speed to half a knot,” he ordered. “Drop back behind me—I’ll creep up slowly and switch on my lights.
”

  “It’s a weird-looking echo. Keeps changing size all the time.”

  “That sounds like our boy. Here we go.”

  The sub was now moving across an endless, slightly tilted plain, still accompanied by its inquisitive retinue of finned dragons. On the TV screen all objects were lost in the haze at a distance of about a hundred and fifty feet; the full power of the ultraviolet projectors could probe the water no farther than this. Franklin switched off his headlights and all external illumination, and continued his cautious approach using the sonar screen alone.

  At five hundred feet the echo began to show its unmistakable structure; at four hundred feet there was no longer any doubt; at three hundred feet Franklin’s escort of fish suddenly fled at high speed as if aware that this was no healthy spot. At two hundred feet he turned on his visual lures, but he waited a few seconds before switching on the searchlights and TV.

  A forest was walking across the sea bed—a forest of writhing, serpentine trunks. The great squid froze for a moment as if impaled by the searchlights; probably it could see them, though they were invisible to human eyes. Then it gathered up its tentacles with incredible swiftness, folding itself into a compact, streamlined mass—and shot straight toward the sub under the full power of its own jet propulsion.

  It swerved at the last minute, and Franklin caught a glimpse of a huge and lidless eye that must have been at least a foot in diameter. A second later there was a violent blow on the hull, followed by a scraping sound as of great claws being dragged across metal. Franklin remembered the scars he had so often seen on the blubbery hides of sperm whales, and was glad of the thickness of steel that protected him. He could hear the wiring of his external illumination being ripped away; no matter—it had served its purpose.
