27 Mirror of the Past Moses Kaldor held the module up to the light, peering into it as if he could read its contents. ‘It will always seem a miracle to me,’ he said, ‘that I can hold a million books between my thumb and forefinger. I wonder what Caxton and Gutenberg would have thought.’ ‘Who?’ Mirissa asked. ‘The men who started the human race reading. But there’s a price we have to pay now for our ingenuity. Sometimes I have a little nightmare and imagine that one of these modules contains some piece of absolutely vital information – say the cure for a raging epidemic – but the address has been lost. It’s on one of those billion pages, but we don’t know which. How frustrating to hold the answer in the palm of your hand and not be able to find it!’ ‘I don’t see the problem,’ the captain’s secretary said. As an expert on information storage and retrieval, Joan LeRoy had been helping with the transfers between Thalassa Archives and the ship. ‘You’ll know the key words; all you have to do is set up a search program. Even a billion pages could be checked in a few seconds.’ ‘You’ve spoiled my nightmare.’ Kaldor sighed. Then he brightened. ‘But often you even don’t know the key words. How many times have you come across something that you didn’t know you needed – until you found it?’ ‘Then you’re badly organized,’ said Lieutenant LeRoy. They enjoyed these little tongue-in-cheek exchanges, and Mirissa was not always sure when to take them seriously. Joan and Moses did not deliberately try to exclude her from their conversations, but their worlds of experience were so utterly different from hers that she sometimes felt that she was listening to a dialogue in an unknown language. ‘Anyway, that completes the Master Index. We each know what the other has; now we merely – merely! – have to decide what we’d like to transfer. It may be inconvenient, not to say expensive, when we’re seventy-five lights apart.’ ‘Which reminds me,’ Mirissa said. ‘I don’t suppose I should tell you – but there was a delegation from North Island here last week. The president of the science academy, and a couple of physicists.’ ‘Let me guess. The quantum drive.’ ‘Right.’ ‘How did they react?’ ‘They seemed pleased – and surprised – that it really was there. They made a copy, of course.’ ‘Good luck to them; they’ll need it. And you might tell them this. Someone once said that the QD’s real purpose is nothing as trivial as the exploration of the Universe. We’ll need its energies one day to stop the cosmos’ collapsing back into the primordial Black Hole – and to start the next cycle of existence.’ There was an awed silence, then Joan LeRoy broke the spell. ‘Not in the lifetime of this administration. Let’s get back to work. We still have megabytes to go, before we sleep.’ It was not all work, and there were times when Kaldor simply had to get away from the Library Section of First Landing in order to relax. Then he would stroll across to the art gallery, take the computer-guided tour through the Mother Ship (never the same route twice – he tried to cover as much ground as possible) or let the Museum carry him back in time. There was always a long line of visitors – mostly students, or children with their parents – for the Terrama displays. Sometimes Moses Kaldor felt a little guilty at using his privileged status to jump to the head of the queue. He consoled himself with the thought that the Lassans had a whole lifetime in which they could enjoy these panoramas of the world they had never known; he had only months in which to revisit his lost home. He found it very difficult to convince his new friends that Moses Kaldor had never been in the scenes they sometimes watched together. Everything they saw was at least eight hundred years in his own past, for the Mother Ship had left Earth in 2751 – and he had been born in 3541. Yet occasionally there would be a shock of recognition, and some memory would come flooding back with almost unbearable power. The ‘Sidewalk Cafe’ presentation was the most uncanny, and the most evocative. He would be sitting at a small table, under an awning, drinking wine or coffee, while the life of a city flowed past him. As long as he did not get up from the table, there was absolutely no way in which his senses could distinguish the display from reality. In microcosm, the great cities of Earth were brought back to life. Rome, Paris, London, New York – in summer and winter, by night and day, he watched the tourists and businessmen and students and lovers go about their ways. Often, realizing that they were being recorded, they would smile at him across the centuries, and it was impossible not to respond. Other panoramas showed no human beings at all, or even any of the productions of Man. Moses Kaldor looked again, as he had done in that other life, upon the descending smoke of Victoria Falls, the Moon rising above the Grand Canyon, the Himalayan snows, the ice cliffs of Antarctica. Unlike the glimpses of the cities, these things had not changed in the thousand years since they were recorded. And though they had existed long before Man, they had not outlasted him.
28 The Sunken Forest The scorp did not seem to be in a hurry; it took a leisurely ten days to travel fifty kilometres. One curious fact was quickly revealed by the sonar beacon that had been attached, not without difficulty, to the angry subject’s carapace. The path it traced along the seabed was perfectly straight, as if it knew precisely where it was going. Whatever its destination might be, it seemed to have found it, at a depth of two hundred and fifty metres. Thereafter, it still kept moving around, but inside a very limited area. This continued for two more days; then the signals from the ultrasonic pinger suddenly stopped in mid-pulse. That the scorp had been eaten by something even bigger and nastier than itself was far too naive an explanation. The pinger was enclosed in a tough metal cylinder; any conceivable arrangement of teeth, claws, or tentacles would take minutes – at the very least – to demolish it, and it would continue to function quite happily inside any creature that swallowed it whole. This left only two possibilities, and the first was indignantly denied by the staff of the North Island Underwater Lab. ‘Every single component had a back-up,’ the director said. ‘What’s more, there was a diagnostic pulse only two seconds earlier; everything was normal. So it could not have been an equipment failure.’ That left only the impossible explanation. The pinger had been switched off. And to do that, a locking-bar had to be removed. It could not happen by accident; only by curious meddling – or deliberate intent. * * * The twenty metre twin-hull Calypso was not merely the largest, but the only, oceanographic research vessel on Thalassa. It was normally based on North Island, and Loren was amused to note the good-natured banter between its scientific crew and their Tarnan passengers, whom they pretended to treat as ignorant fishermen. For their part, the South Islanders lost no opportunity of boasting to the Northers that they were the ones who had discovered the scorps. Loren did not remind them that this was not strictly in accord with the facts. It was a slight shock to meet Brant again, though Loren should have expected it, since the other had been partly responsible for Calypso’s new equipment. They greeted each other with cool politeness, ignoring the curious or amused glances of the other passengers. There were few secrets on Thalassa; by this time everyone would know who was occupying the main guest-room of the Leonidas home. The small underwater sledge sitting on the afterdeck would have been familiar to any oceanographer of the last two thousand years. Its metal framework carried three television cameras, a wire basket to hold samples collected by the remote-controlled arm, and an arrangement of water-jets that permitted movement in any direction. Once it had been lowered over the side, the robot explorer could send its images and information back through a fibre-optic cable not much thicker than the lead of a pencil. The technology was centuries old – and still perfectly adequate. Now the shoreline had finally disappeared, and for the first time Loren found himself completely surrounded by water. He recalled his anxiety on that earlier trip with Brant and Kumar when they had travelled hardly a kilometre from the beach. This time, he was pleased to discover, he felt slightly more at ease, despite the presence of his rival. Perhaps it was because he was on a much larger boat … ‘That’s odd,’ Brant said, ‘I’ve never seen kelp this far to the west.’ At first Loren could see nothing; then he noticed the dark stain low in the water ahead. A few minutes later, the boat was nosing its way through a loose mass of floating vegetation, and the captain slowed speed to a crawl. ‘We’re almost there, anyway,’ he said. ‘No point in clogging our intakes with this stuff. Agreed, Brant?’ Brant adjusted the cursor on the display screen and took a reading. ‘Yes – we’re only fifty metres from where we lost the pinger. Depth two hundred and ten. Let’s get the fish overboard.’ ‘Just a minute,’ one of the Norther scientists said. ‘We spent a lot of time and money on that machine, and it’s the only one in the world. Suppose it gets tangled up in that damned kelp?” There was a thoughtful silence; then Kumar, who had been uncharacteristically quiet – perhaps overawed by the high-powered talent from North Island – put in a diffident word. ‘It looks much worse from here. Ten metres down, there are almost no leaves – only the big stems, with plenty of room between them. It’s like a forest.’ Yes, thought Loren, a submarine forest, with fish swimming between the slender, sinuous trunks. While the other scientists were watching the main video screen and the multiple displays of instrumentation, he had put on a set of full-vision goggles, excluding everything from his field of view except the scene ahead of the slowly descending robot. Psychologically, he was no longer on the deck of Calypso; the voices of his companions seemed to come from another world that had nothing to do with him. He was an explorer entering an alien universe, not knowing what he might encounter. It was a restricted, almost monochrome universe; the only colours were soft blues and greens, and the limit of vision was less than thirty metres away. At any one time he could see a dozen slender trunks, supported at regular intervals by the gas-filled bladders that gave them buoyancy, reaching up from the gloomy depths and disappearing into the luminous ‘sky’ overhead. Sometimes he felt that he was walking through a grove of trees on a dull, foggy day: then a school of darting fish destroyed the illusion. ‘Two hundred fifty metres,’ he heard someone call. ‘We should see the bottom soon. Shall we use the lights? The image quality is deteriorating.’ Loren had scarcely noticed any change, because the automatic controls had maintained the picture brilliance. But he realized that it must be almost completely dark at this depth; a human eye would have been virtually useless. ‘No – we don’t want to disturb anything until we have to. As long as the camera’s operating, let’s stick to available light.’ ‘There’s the bottom! Mostly rock – not much sand.’ ‘Naturally. Macrocystis thalassi needs rocks to cling to – it’s not like the free-floating Sargassum.’ Loren could see what the speaker meant. The slender trunks ended in a network of roots, grasping rock-outcroppings so firmly that no storms or surface currents could dislodge them. The analogy with a forest on land was even closer than he had thought. Very cautiously, the robot surveyor was working its way into the submarine forest, playing out its cable behind it. There seemed no risk of becoming entangled in the serpentine trunks that reared up to the invisible surface, for there was plenty of space between the giant plants. Indeed, they might have been deliberately – The scientists looking at the monitor screen realized the incredible truth just a few seconds after Loren. ‘Krakan!’ one of them whispered. ‘This isn’t a natural forest -it’s a – plantation?
