The City and the Stars

by Arthur C. Clarke

  There was obviously someone at home, for a small Sand Flea was parked outside the building.

  “They’re quite a sociable crowd,” said the driver as he brought the vehicle to a halt. “It’s a pretty dull life up here and they’re always glad to see people. And there’ll be room inside the dome for us to stretch our legs and have dinner in comfort.”

  “Surely we can’t expect them to provide a meal for us,” protested Gibson, who had a dislike of incurring obligations he couldn’t readily discharge. The driver looked genuinely surprised; then he laughed heartily.

  “This isn’t Earth, you know. On Mars, everyone helps everyone else— we have to, or we’d never get anywhere. But I’ve brought our provisions along— all I want to use is their stove. If you’d ever tried to cook a meal inside a Sand Flea with four aboard you’d know why.”

  As predicted, the two astronomers on duty greeted them warmly, and the little plastic bubble’s air-conditioning plant was soon dealing with the odors of cookery. While this was going on, Mackay had grabbed the senior member of the staff and started a technical discussion about the Observatory’s work. Most of it was quite over Gibson’s head, but he tried to gather what he could from the conversation.

  Most of the work done here was, it seemed, positional astronomy— the dull but essential business of finding longitudes and latitudes, providing time signals and linking radio fixes with the main Martian grid. Very little observational work was done at all; the huge instruments on Earth’s moon had taken that over long ago, and these small telescopes, with the additional handicap of an atmosphere above them, could not hope to compete. The parallaxes of a few nearer stars had been measured, but the very slight increase of accuracy provided by the wider orbit of Mars made it hardly worth while.

  As he ate his dinner— finding to his surprise that his appetite was better than at any time since reaching Mars— Gibson felt a glow of satisfaction at having done a little to brighten the dull lives of these devoted men. Because he had never met enough of them to shatter the illusion, Gibson had an altogether disproportionate respect for astronomers, whom he regarded as leading lives of monkish dedication on their remote mountain eyries. Even his first encounter with the excellent cocktail bar on Mount Palomar had not destroyed this simple faith.

  After the meal, at which everyone helped so conscientiously with the washing-up that it took twice as long as necessary, the visitors were invited to have a look through the large reflector. Since it was early afternoon, Gibson did not imagine that there would be a great deal to see; but this was an oversight on his part.

  For a moment the picture was blurred, and he adjusted the focusing screw with clumsy fingers. It was not easy to observe with the special eyepiece needed when one was wearing a breathing mask, but after a while Gibson got the knack of it.

  Hanging in the field of view, against the almost black sky near the zenith, was a beautiful pearly crescent like a three-day-old moon. Some markings were just visible on the illuminated portion, but though Gibson strained his eyes to the utmost he could not identify them. Too much of the planet was in darkness for him to see any of the major continents.

  Not far away floated an identically shaped but much smaller and fainter crescent, and Gibson could distinctly see some of the familiar craters along its edge. They formed a beautiful couple, the twin planets Earth and Moon, but somehow they seemed too remote and ethereal to give him any feeling of homesickness or regret for all that he had left behind.

  One of the astronomers was speaking, his helmet held close to Gibson’s.

  “When it’s dark you can see the lights of the cities down there on the night side. New York and London are easy. The prettiest sight, though, is the reflections of the Sun off the sea. You get it near the edge of the disc when there’s no cloud about— a sort of brilliant, shimmering star. It isn’t visible now because it’s mostly land on the crescent portion.”

  Before leaving the Observatory, they had a look at Deimos, which was rising in its leisurely fashion in the east. Under the highest power of the telescope the rugged little moon seemed only a few kilometers away, and to his surprise Gibson could see the Ares quite clearly as two gleaming dots close together. He also wanted to look at Phobos, but the inner moon had not yet risen.

  When there was nothing more to be seen, they bade farewell to the two astronomers, who waved back rather glumly as the Flea drove off along the brow of the hill. The driver explained that he wanted to make a private detour to pick up some rock specimens, and as to Gibson one part of Mars was very much like another he raised no objection.

  There was no real road over the hills, but ages ago all irregularities had been worn away so that the ground was perfectly smooth. Here and there a few stubborn boulders still jutted above the surface, displaying a fantastic riot of color and shape, but these obstacles were easily avoided. Once or twice they passed small trees— if one could call them that— of a type which Gibson had never seen before. They looked rather like pieces of coral, completely stiff and petrified. According to their driver they were immensely old, for though they were certainly alive no one had yet been able to measure their rate of growth. The smallest value which could be derived for their age was fifty thousand years, and their method of reproduction was a complete mystery.

  Towards mid-afternoon they came to a low but beautifully colored cliff— “Rainbow Ridge,” the geologist called it— which reminded Gibson irresistibly of the more flamboyant Arizona canyons, though on a much smaller scale. They got out of the Sand Flea and, while the driver chipped off his samples, Gibson happily shot off half a reel of the new Multichrome film he had brought with him for just such occasions. If it could bring out all those colors perfectly it must be as good as the makers claimed, but unfortunately he’d have to wait until he got back to Earth before it could be developed. No one on Mars knew anything about it.

  “Well,” said the driver, “I suppose it’s time we started for home if we want to get back for tea. We can drive back the way we came, and keep to the high ground, or we can go round behind the hills. Any preferences?”

  “Why not drive down into the plain? That would be the most direct route,” said Mackay, who was now getting a little bored.

  “And the slowest— you can’t drive at any speed through those overgrown cabbages.”

  “I always hate retracing my steps,” said Gibson. “Let’s go round the hills and see what we can find there.”

  The driver grinned.

  “Don’t raise any false hopes. It’s much the same on both sides. Here we go!”

  The Flea bounced forward and Rainbow Ridge soon disappeared behind them. They were now winding their way through completely barren country, and even the petrified trees had vanished. Sometimes Gibson saw a patch of green which he thought was vegetation, but as they approached it invariably turned into another mineral outcrop. This region was fantastically beautiful, a geologist’s paradise, and Gibson hoped that it would never be ravaged by mining operations. It was certainly one of the show places of Mars.

  They had been driving for half an hour when the hills sloped down into a long, winding valley which was unmistakably an ancient watercourse. Perhaps fifty million years ago, the driver told them, a great river had flowed this way to lose its waters in the Mare Erythraeum— one of the few Martian “seas” to be correctly, if somewhat belatedly, named. They stopped the Flea and gazed down the empty river bed with mingled feelings. Gibson tried to picture this scene as it must have appeared in those remote days, when the great reptiles ruled the Earth and Man was still a dream of the distant future. The red cliffs would scarcely have changed in all that time, but between them the river would have made its unhurried way to the sea, flowing slowly under the weak gravity. It was a scene that might almost have belonged to Earth; and had it ever been witnessed by intelligent eyes? No one knew. Perhaps there had indeed been Martians in those days, but time had buried them completely.

  The ancient river had left a legacy, fo
r there was still moisture along the lower reaches of the valley. A narrow band of vegetation had come thrusting up from Erythraeum, its brilliant green contrasting vividly with the crimson of the cliffs. The plants were those which Gibson had already met on the other side of the hills, but here and there were strangers. They were tall enough to be called trees, but they had no leaves— only thin, whiplike branches which continually trembled despite the stillness of the air. Gibson thought they were some of the most sinister things he had ever seen— just the sort of ominous plant that would suddenly flick out its tentacles at an unsuspecting passer-by. In fact, as he was perfectly well aware, they were as harmless as everything else on Mars.

  They had zigzagged down into the valley and were climbing the other slope when the driver suddenly brought the Flea to a halt.

  “Hello!” he said. “This is odd. I didn’t know there was any traffic in these parts.”

  For a moment Gibson, who was not really as observant as he liked to think, was at a loss. Then he noticed a faint track running along the valley at right angles to their present path.

  “There have been some heavy vehicles here,” said the driver. “I’m sure this track didn’t exist the last time I came this way— let’s see, about a year ago. And there haven’t been any expeditions into Erythraeum in that time.”

  “Where does it lead?” asked Gibson.

  “Well, if you go up the valley and over the top you’ll be back in Port Lowell; that was what I intended to do. The other direction only leads out into the Mare.”

  “We’ve got time— let’s go along it a little way.”

  Willingly enough, the driver swung the Flea around and headed down the valley. From time to time the track vanished as they went over smooth, open rock, but it always reappeared again. At last, however, they lost it completely.

  The driver stopped the Flea.

  “I know what’s happened,” he said. “There’s only one way it could have gone. Did you notice that pass about a kilometer back? Ten to one it leads up there.”

  “And where would that take anyone?”

  “That’s the funny thing— it’s a complete cul-de-sac. There’s a nice little amphitheater about two kilometers across, but you can’t get out of it anywhere except the way you came in. I spent a couple of hours there once when we did the first survey of this region. It’s quite a pretty little place, sheltered and with some water in the spring.”

  “A good hide-out for smugglers,” laughed Gibson.

  The driver grinned.

  “That’s an idea. Maybe there’s a gang bringing in contraband beefsteaks from Earth. I’d settle for one a week to keep my mouth shut.”

  The narrow pass had obviously once contained a tributary of the main river, and the going was a good deal rougher than in the main valley. They had not driven very far before it became quite clear that they were on the right track.

  “There’s been some blasting here,” said the driver. “This bit of road didn’t exist when I came this way. I had to make a detour up that slope, and nearly had to abandon the Flea.”

  “What do you think’s going on?” asked Gibson, now getting quite excited.

  “Oh, there are several research projects that are so specialized that one doesn’t hear a lot about them. Some things can’t be done near the city, you know. They may be building a magnetic observatory here— there’s been some talk of that. The generators at Port Lowell would be pretty well shielded by the hills. But I don’t think that’s the explanation, for I’d have heard— Good Lord!”

  They had suddenly emerged from the pass, and before them lay an almost perfect oval of green, flanked by the low, ocher hills. Once this might have been a lovely mountain lake; it was still a solace to the eye weary of lifeless, multicolored rock. But for the moment Gibson scarcely noticed the brilliant carpet of vegetation; he was too astonished by the cluster of domes, like a miniature of Port Lowell itself, grouped at the edge of the little plain.

  They drove in silence along the road that had been cut through the living green carpet. No one was moving outside the domes, but a large transporter vehicle, several times the size of the Sand Flea, showed that someone was certainly at home.

  “This is quite a set-up,” remarked the driver as he adjusted his mask. “There must be a pretty good reason for spending all this money. Just wait here while I go over and talk to them.”

  They watched him disappear into the airlock of the larger dome. It seemed to his impatient passengers that he was gone rather a long time. Then they saw the outer door open again and he walked slowly back towards them.

  “Well?” asked Gibson eagerly as the driver climbed back into the cab. “What did they have to say?”

  There was a slight pause; then the driver started the engine and the Sand Flea began to move off.

  “I say— what about this famous Martian hospitality? Aren’t we invited in?” cried Mackay.

  The driver seemed embarrassed. He looked, Gibson thought, exactly like a man who had just discovered he’s made a fool of himself. He cleared his throat nervously.

  “It’s a plant research station,” he said, choosing his words with obvious care. “It’s not been going for very long, which is why I hadn’t heard of it before. We can’t go inside because the whole place is sterile and they don’t want spores brought in— we’d have to change all our clothes and have a bath of disinfectant.”

  “I see,” said Gibson. Something told him it was no use asking any further questions. He knew, beyond all possibility of error, that his guide had told him only part of the truth— and the least important part at that. For the first time the little discrepancies and doubts that Gibson had hitherto ignored or forgotten began to crystallize in his mind. It had started even before he reached Mars, with the diversion of the Ares from Phobos. And now he had stumbled upon this hidden research station. It had been as big a surprise to their experienced guide as to them, but he was attempting to cover up his accidental indiscretion.

  There was something going on. What it was, Gibson could not imagine. It must be big, for it concerned not only Mars but Phobos. It was something unknown to most of the colonists, yet something they would co-operate in keeping secret when they encountered it.

  Mars was hiding something; and it could only be hiding it from Earth.

  CHAPTER

  10

  The Grand Martian Hotel now had no less than two residents, a state of affairs which imposed a severe strain on its temporary staff. The rest of his shipmates had made private arrangements for their accommodation in Port Lowell, but as he knew no one in the city Jimmy had decided to accept official hospitality. Gibson wondered if this was going to be a success; he did not wish to throw too great a strain on their still somewhat provisional friendship, and if Jimmy saw too much of him the results might be disastrous. He remembered an epigram which his best enemy had once concocted: “Martin’s one of the nicest fellows you could meet, as long as you don’t do it too often.” There was enough truth in this to make it sting, and he had no wish to put it to the test again.

  His life in the Port had now settled down to a fairly steady routine. In the morning he would work, putting on paper his impressions of Mars— rather a presumptuous thing to do when he considered just how much of the planet he had so far seen. The afternoon was reserved for tours of inspection and interviews with the city’s inhabitants. Sometimes Jimmy went with him on these trips, and once the whole of the Ares crew came along to the hospital to see how Dr. Scott and his colleagues were progressing with their battle against Martian fever. It was still too early to draw any conclusions, but Scott seemed fairly optimistic. “What we’d like to have,” he said rubbing his hands ghoulishly, “is a really good epidemic so that we could test the stuff properly. We haven’t enough cases at the moment.”

  Jimmy had two reasons for accompanying Gibson on his tours of the city. In the first place, the older man could go almost anywhere he pleased and so could get into all the interesting places wh
ich might otherwise be out of bounds. The second reason was a purely personal one— his increasing interest in the curious character of Martin Gibson.

  Though they had now been thrown so closely together, they had never reopened their earlier conversation. Jimmy knew that Gibson was anxious to be friends and to make some recompense for whatever had happened in the past. He was quite capable of accepting this offer on a purely impersonal basis, for he realized well enough that Gibson could be extremely useful to him in his career. Like most ambitious young men, Jimmy had a streak of coldly calculating self-interest in his make-up, and Gibson would have been slightly dismayed at some of the appraisals which Jimmy had made of the advantages to be obtained from his patronage.

  It would, however, be quite unfair to Jimmy to suggest that these material considerations were uppermost in his mind. There were times when he sensed Gibson’s inner loneliness— the loneliness of the bachelor facing the approach of middle age. Perhaps Jimmy also realized— though not consciously as yet— that to Gibson he was beginning to represent the son he had never had. It was not a role that Jimmy was by any means sure he wanted, yet there were often times when he felt sorry for Gibson and would have been glad to please him. It is, after all, very difficult not to feel a certain affection towards someone who likes you.

  The accident that introduced a new and quite unexpected element into Jimmy’s life was really very trivial. He had been out alone one afternoon and, feeling thirsty, had dropped into the small café opposite the Administration building. Unfortunately he had not chosen his time well, for while he was quietly sipping a cup of tea which had never been within millions of kilometers of Ceylon, the place was suddenly invaded. It was the twenty-minute afternoon break when all work stopped on Mars— a rule which the Chief Executive had enforced in the interests of efficiency, though everyone would have much preferred to do without it and leave work twenty minutes earlier instead.
