Though he would never have occasion to use them, he was also tested with the special breathing mixtures which enable a man to remain conscious and active at far greater depths. When he did any deep dives, he would not be wearing underwater breathing gear but would be sitting comfortably inside a sub breathing normal air at normal pressure. But a warden had to be a Jack of all underwater trades, and never knew what equipment he might have to use in an emergency.
Burley was no longer scared—as he had once been—at the thought of sharing a two-man training sub with Franklin. Despite the other’s underlying reticence and the mystery which still surrounded him, they were partners now and knew how to work together. They had not yet become friends, but had reached a state which might be defined as one of tolerant respect.
On their first sub run, they kept to the shallow waters between the Great Barrier Reef and the mainland, while Franklin familiarized himself with the controls, and above all with the navigational instruments. If you could run a sub here, said Don, in this labyrinth of reefs and islands, you could run it anywhere. Apart from trying to charge Masthead Island at sixty knots, Franklin performed quite creditably. His fingers began to move over the complex control board with a careful precision which, Don knew, would soon develop into automatic skill. His scanning of the many meters and display screens would soon be unconscious, so that he would not even be aware that he saw them—until something called for his attention.
Don gave Franklin increasingly more complicated tasks to perform, such as tracing out improbable courses by dead reckoning and then checking his position on the sonar grid to see where he had actually arrived. It was not until he was quite sure that Franklin was proficient in handling a sub that they finally went out into deep water over the edge of the continental shelf.
Navigating a Scoutsub was merely the beginning; one had to learn to see and feel with its senses, to interpret all the patterns of information displayed on the control board by the many instruments which were continually probing the underwater world. The sonic senses were, perhaps, the most important. In utter darkness, or in completely turbid water, they could detect all obstacles out to a range of ten miles, with great accuracy and in considerable detail. They could show the contours of the ocean bed, or with equal ease could detect any fish more than two or three feet long that came within half a mile. Whales and the larger marine animals they could spot right out to the extreme limit of range, fixing them with pinpoint accuracy.
Visible light had a more limited role. Sometimes, in deep ocean waters far from the eternal rain of silt which sloughs down from the edges of the continents, it was possible to see as much as two hundred feet—but that was rare. In shallow coastal waters, the television eye could seldom peer more than fifty feet, but within its range it gave a definition unmatched by the sub’s other senses.
Yet the subs had not only to see and feel; they also had to act. Franklin must learn to use the whole armory of tools and weapons: borers to collect specimens of the sea bed, meters to check the efficiency of the fences, sampling devices, branders for painlessly marking un-co-operative whales, electric probes to discourage marine beasts that became too inquisitive—and, most seldom used of all, the tiny torpedoes and poisoned darts that could slay in seconds the mightiest creatures of the seas.
In daily cruises far out into the Pacific, Franklin learned to use these tools of his new trade. Sometimes they went through the fence, and it seemed to Franklin that he could feel its eternal high-pitched shrieking in his very bones. Halfway around the world it now extended, its narrow fans of radiation reaching up to the surface from the deeply submerged generators.
What, wondered Franklin, would earlier ages have thought of this? In some ways it seemed the greatest and most daring of all man’s presumptions. The sea, which had worked its will with man since the beginning of time, had been humbled at last. Not even the conquest of space had been a greater victory than this.
And yet—it was a victory that could never be final. The sea would always be waiting, and every year it would claim its victims. There was a roll of honor that Franklin had glimpsed briefly during his visit to the head office. Already it bore many names, and there was room for many more.
Slowly, Franklin was coming to terms with the sea, as must all men who have dealings with it. Though he had had little time for nonessential reading, he had dipped into Moby Dick, which had been half-jokingly, half-seriously called the bible of the Bureau of Whales. Much of it had seemed to him tedious, and so far removed from the world in which he was living that it had no relevance. Yet occasionally Melville’s archaic, sonorous prose touched some chord in his own mind, and gave him a closer understanding of the ocean which he, too, must learn to hate and love.
Don Burley, however, had no use at all for Moby Dick and frequently made fun of those who were always quoting it.
“We could show Melville a thing or two!” he had once remarked to Franklin, in a very condescending tone.
“Of course we could,” Franklin had answered. “But would you have the guts to stick a spear into a sperm whale from an open boat?”
Don did not reply. He was honest enough to admit that he did not know the answer.
Yet there was one question he was now close to answering. As he watched Franklin learn his new skills, with a swiftness which could undoubtedly make him a first warden in no more than four or five years, he knew with complete certainty what his pupil’s last profession had been. If he chose to keep it a secret, that was his own affair. Don felt a little aggrieved by such lack of trust; but sooner or later, he told himself, Franklin would confide in him.
Yet it was not Don who was the first to learn the truth. By the sheerest of accidents, it was Indra.
CHAPTER VI
THEY NOW MET at least once a day in the mess, though Franklin had not yet made the irrevocable, almost unprecedented, step of moving from his table to the one at which the research staff dined. That would be a flamboyant declaration which would set every tongue on the island wagging happily, and in any case it would not be justified by the circumstances. As far as Indra and Franklin were concerned, the much-abused phrase “we’re just friends” was still perfectly true.
Yet it was also true that they had grown very fond of each other, and that almost everyone except Don was aware of it. Several of Indra’s colleagues had said to her approvingly, “You’re thawing out the iceberg,” and the compliment had flattered her. The few people who knew Franklin well enough to banter with him had made warning references to Don, pointing out that first wardens had reputations to maintain. Franklin’s reaction had been a somewhat forced grin, concealing feelings which he could not fully analyze himself.
Loneliness, the need to escape from memories, a safety valve to guard him against the pressure under which he was working—these factors were at least as important as the normal feelings of any man for a girl as attractive as Indra. Whether this companionship would develop into anything more serious, he did not know. He was not even sure if he wished it to do so.
Nor, for her part, was Indra, though her old resolve was weakening. Sometimes she indulged in reveries wherein her career took very much of a second place. One day, of course, she was going to marry, and the man she would choose would be very much like Franklin. But that it might be Franklin was a thought from which she still shied away.
One of the problems of romance on Heron Island was that there were far too many people in too small a space. Even the fragment that was left of the original forest did not provide enough seclusion. At night, if one wandered through its paths and byways, carrying a flashlight to avoid the lowhanging branches, one had to be very tactful with the beam. One was liable to find that favorite spots had already been requisitioned, which would be extremely frustrating if there was nowhere else to go.
The fortunate scientists at the Research Station, however, had an invaluable escape route. All the large surface craft and all the underwater vessels belonged to Administration, though they
were made available to the lab for official business. But by some historical accident, the lab had a tiny private fleet consisting of one launch and two catamarans. No one was quite sure who owned the latter, and it was noticeable that they were always at sea when the auditors arrived for the annual inventory.
The little cats did a great deal of work for the lab, since they drew only six inches of water and could operate safely over the reef except at low tide. With a stiff wind behind them, they could do twenty knots with ease, and races between the two craft were frequently arranged. When they were not being used for other business, the scientists would sail them to the neighboring reefs and islands to impress their friends—usually of the opposite sex—with their prowess as seamen.
It was a little surprising that ships and occupants had always come back safely from these expeditions. The only casualties had been to morale; one first warden of many years seniority had had to be carried off the boat after a pleasure trip, and had sworn that nothing would ever induce him to travel on the surface of the sea again.
When Indra suggested to Franklin that he might like to sail to Masthead Island, he accepted at once. Then he said cautiously : “Who’ll run the boat?”
Indra looked hurt.
“I will, of course,” she answered. “I’ve done it dozens of times.” She seemed to be half-expecting him to doubt her competence, but Franklin knew better than to do so. Indra, he had already discovered, was a very levelheaded girl—perhaps too levelheaded. If she said she could do a job, that was that.
There was still, however, one other point to be settled. The cats could take four people; who would the other two be?
Neither Indra nor Franklin actually voiced the final decision. It hovered in the air while they discussed various possible companions, starting with Don and working down the list of Indra’s friends at the lab. Presently the conversation died out into one of those portentous pauses which can sometimes occur even in a roomful of chattering people.
In the sudden silence, each realized that the other was thinking the same thought, and that a new phase had begun in their relationship. They would take no one with them to Masthead; for the first time, they would have the solitude that had never been possible here. That this could lead only to one logical conclusion they refused to admit, even to themselves, the human mind having a remarkable capacity for self-deceit.
It was well into the afternoon before they were able to make all their arrangements and escape. Franklin felt very guilty about Don, and wondered what his reactions would be when he found out what had happened. He would probably be mortified, but he was not the sort to hold a grudge and he would take it like a man.
Indra had thought of everything. Food, drinks, sunburn lotion, towels—she had overlooked nothing that such an expedition might need. Franklin was impressed by her thoroughness, and was amused to find himself thinking that so competent a woman would be very useful to have around the house. Then he reminded himself hastily that women who were too efficient were seldom happy unless they ran their husbands’ lives as well as their own.
There was a steady wind blowing from the mainland, and the cat bounded across the waves like a living creature. Franklin had never before been in a sailing boat, and he found the experience an exhilarating one. He lay back on the worn but comfortable padding of the open cockpit, while Heron Island receded into the distance at an astonishing speed. It was restful to watch the twin, creamy wakes trace their passage across the sea, and to caress with the eye the straining, power-filled curves of the sails. With a mild and fleeting regret, Franklin wished that all man’s machines could be as simple and efficient as this one. What a contrast there was between this vessel and the crowded complexities of the subs he was now learning to handle! The thought passed swiftly; there were some tasks which could not be achieved by simple means, and one must accept the fact without complaint.
On their left, they were now skirting the long line of rounded coral boulders which centuries of storms had cast up upon the edge of the Wistari Reef. The waves were breaking against the submerged ramparts with a relentless and persistent fury which had never impressed Franklin so much as now. He had seen them often enough before—but never from so close at hand, in so frail a craft.
The boiling margin of the reef fell astern; now they had merely to wait while the winds brought them to their goal. Even if the wind failed—which was most unlikely—they could still make the trip on the little auxiliary hydro-jet engine, though that would only be used as a last resort. It was a matter of principle to return with a full fuel tank.
Although they were now together and alone for almost the first time since they had met, neither Franklin nor Indra felt any need to talk. There seemed a silent communion between them which they did not wish to break with words, being content to share the peace and wonder of the open sea and the open sky. They were enclosed between two hemispheres of flawless blue, clamped together at the misty rim of the horizon, and nothing else of the world remained. Even time seemed to have faltered to a stop; Franklin felt he could lie here forever, relaxing in the gentle motion of the boat as it skimmed effortlessly over the waves.
Presently a low, dark cloud began to solidify, then to reveal itself as a tree-clad island with its narrow sandy shore and inevitable fringing reef. Indra bestirred herself and began to take an active interest in navigation once more, while Franklin looked rather anxiously at the breakers which seemed to surround the island in one continuous band.
“How are we going to get in?” he asked.
“Round the lee side; it won’t be rough there, and the tide should be high enough for us to go in across the reef. If it isn’t, we can always anchor and wade ashore.”
Franklin was not altogether happy about so casual an approach to what seemed a serious problem, and he could only hope that Indra really did know what she was doing. If she made a mistake, they might have an uncomfortable though not particularly dangerous swim ahead, followed after a long wait by an ignominious rescue when someone came from the lab to look for them.
Either it was easier than it appeared to an anxious novice, or else Indra’s seamanship was of a high order. They circled halfway around the island, until they came to a spot where the breakers subsided into a few choppy waves. Then Indra turned the prow of the cat toward the land, and headed straight for shore.
There were no sounds of grinding coral or splintering plastic. Like a bird, the catamaran flew in across the narrow edge of the reef, now clearly visible just below the broken and unsettled water. It skimmed past this danger zone, and then was over the peaceful surface of the lagoon, seeming to gain speed as it approached the beach. Seconds before impact, Indra furled the mainsail. With a soft thud, the vessel hit the sand and coasted up the gentle slope, coming to rest with more than half its length above the water line.
“Here we are,” said Indra. “One uninhabited coral island, in full working order.” She seemed more relaxed and lighthearted than Franklin had ever before seen her; he realized that she, too, had been working under pressure and was glad to escape from the daily routine for a few hours. Or was it the stimulating effect of his company that was turning her from a serious student into a vivacious girl? Whatever the explanation, he liked the change.
They climbed out of the boat and carried their gear up the beach into the shade of the coconut palms, which had been imported into these islands only during the last century to challenge the predominance of the Pisonia and the stilt-rooted pandanus. It seemed that someone else had also been here recently, for curious tracks apparently made by narrow-gauge caterpillar treads marched up out of the water and vanished inland. They would have been quite baffling to anyone who did not know that the big turtles had been coming ashore to lay their eggs.
As soon as the cat had been made secure, Franklin and Indra began a tour of exploration. It was true that one coral island was almost exactly the same as another; the same pattern was repeated endlessly over and over again, with few variations. Yet
even when one was aware of that, and had landed on dozens of islands, every new one presented a fresh challenge which had to be accepted.
They began the circumnavigation of their little world, walking along the narrow belt of sand between the forest and the sea. Sometimes, when they came to a clearing, they made short forays inland, deliberately trying to lose themselves in the tangle of trees so that they could pretend that they were in the heart of Africa and not, at the very most, a hundred yards from the sea.
Once they stopped to dig with their hands at the spot where one of the turtle tracks terminated on a flat-ended sand dune. They gave up when they were two feet down and there was still no sign of the leathery, flexible eggs. The mother turtle, they solemnly decided, must have been making false trails to deceive her enemies. For the next ten minutes, they elaborated this fantasy into a startling thesis on reptile intelligence, which, far from gaining Indra new qualifications, would undoubtedly have cost her the degree she already possessed.
Inevitably the time came when, having helped each other over a patch of rough coral, their hands failed to separate even though the path was smooth once more. Neither speaking, yet each more conscious of the other’s presence than they had ever been before, they walked on in the silence of shared contentment.
At a leisurely stroll, pausing whenever they felt like it to examine some curiosity of the plant or animal world, it took them almost two hours to circumnavigate the little island. By the time they had reached the cat they were very hungry, and Franklin began to unpack the food hamper with unconcealed eagerness while Indra started working on the stove.
