There was no risk of getting lost in Central City. With one exception each of the seven interconnected domes was laid out in the same pattern of radiating avenues and concentric ring-roads. The exception was Dome Five, the main industrial and production center, which was virtually one vast factory and which Sadler decided to leave alone.
He wandered at random for some time, going where his stray impulses took him. He wanted to get the “feel” of the place, for he realized it was completely impossible to know the city properly in the short time at his disposal. There was one thing about Central City that struck him at once—it had a personality, a character of its own. No one can say why this is true of some cities and not of others, and Sadler felt a little surprised that it should be of such an artificial environment as this. Then he remembered that all cities, whether on Earth or on the Moon, were equally artificial…
The roads were narrow, the only vehicles small, three-wheeled Open cars that cruised along at less than thirty kilometers an hour and appeared to be used exclusively for freight rather than passengers. It was some time before Sadler discovered the automatic subway that linked the outer six domes in a great ring, passing under the center of each. It was really a glorified conveyor belt, and moved in a counterclockwise direction only. If you were unlucky, you might have to go right round the city to get to the adjacent dome, but as the circular tour took only about five minutes, this was no great hardship.
The shopping center, and main repository of lunar chic, was in Dome One. Here also lived the senior executives and technicians—the most senior of all in houses of their own. Most of the residential buildings had roof gardens, where plants imported from Earth ascended to improbable heights in this low gravity. Sadler kept his eyes open for any lunar vegetation, but saw no signs of it. He did not know that there was a strict rule against bringing the indigenous plants into the domes. An oxygen-rich atmosphere, it had been found, over-stimulated them so that they ran riot and promptly died, producing a stench which had to be experienced to be believed when their sulphur-loaded organisms began to decay.
Most of the visitors from Earth were to be found here. Sadler, a selenite of eight days’ standing, found himself eying the obvious newcomers with amused contempt. Many of them had hired weight-belts as soon as they entered the city, under the impression that this was the safest thing to do. Sadler had been warned about this fallacy in time, and so had avoided contributing to what was really a mild racket. It was true that if you loaded yourself down with lead, there was less danger of soaring off the ground with incautious steps, and perhaps terminating the trajector upon your head. But surprisingly few people realized the distinction between weight and inertia which made these belts of such dubious value. When one tried to start moving, or to stop in a hurry, one quickly found that though a hundred kilos of lead might weigh only sixteen kilos here, it had exactly the same momentum as it did on Earth.
From time to time, as he made his way through the scanty crowds and roamed from shop to shop, Sadler ran into friends from the Observatory. Some of them were already festooned with parcels as they made up for a week’s compulsory saving. Most of the younger members of the staff, male and female, had acquired companions. Sadler surmised that though the Observatory might be self-sufficient in most matters, there were others which demanded some variety.
The clear, bell-like note, thrice repeated, caught him unaware. He looked around him, but could not locate its source. At first it seemed that no one was taking any notice of the signal, whatever it might mean. Then he observed that the streets were slowly clearing—and that the sky was getting darker.
Clouds had come up over the sun. They were black and ragged, their edges flame-fringed as the sunlight spilled past them. Once again, Sadler marveled at the skill with which these images—for they could be nothing else—were projected on the dome. No actual thunderstorm could have seemed more realistic, and when the first rumble rolled round the sky he did not hesitate to look for shelter. Even if the streets had not already emptied themselves, he would have guessed that the organizers of this storm were going to omit none of the details…
The little sidewalk cafe was crowded with other refugees when the initial drops came down, and the first fiery tongue of lightning licked across the heavens. Sadler could never see lightning without counting the seconds before the thunder peal. It came when he had got to “Six,” making it two kilometers away. That, of course, would put it well outside the dome, in the soundless vacuum of space. Oh well, one had to allow some artistic license, and it wasn’t fair to quibble over points like this.
Thicker and heavier came the rain, more and more continuous the flashes. The roads were running with water, and for the first time Sadler became aware of the shallow gutters which, if he had seen them before, he had dismissed without a second thought. It was not safe to take anything for granted here; you had to keep stopping and asking yourself “What function does this serve—What’s it doing here on the Moon? Is it even what I think it is?” Certainly, now he came to consider the matter, a gutter was as unexpected a thing to see in Central City as a snow plow. But perhaps even that—
Sadler turned to his closest neighbor, who was watching the storm with obvious admiration.
“Excuse me,” he said, “but how often does this sort of thing happen?”
“About twice a day—lunar day, that is,” came the reply. “It’s always announced a few hours in advance, so that it won’t interfere with business.”
“I don’t want to be too inquisitive,” continued Sadler, fearing that was just what he was, “but I’m surprised at the trouble you’ve gone to. Surely all this realism isn’t necessary?”
“Perhaps not, but we like it. We’ve got to have some rain, remember, to keep the place clean and deal with the dust. So we try to do it properly.”
If Sadler had any doubts on that score, they were dispelled when the glorious double rainbow arched out of the clouds. The last drops spattered on the sidewalk; the thunder dwindled away to an angry, distant mutter. The show was over, and the glistening streets of Central City began to fill with life once more.
Sadler remained in the cafe for a meal, and after a little hard bargaining managed to get rid of some terrestrial currency at only a trifle below the market rate. The food, somewhat to his surprise, was excellent. Every bit must have been synthesized or grown in the yeast and chlorella tanks, but it had been blended and processed with great skill. The trouble with Earth, Sadler mused, was that it could take food for granted, and seldom gave the matter the attention it deserved. Here, on the other hand, food was not something that a bountiful Nature, with a little prompting, could be relied upon to provide. It had to be designed and produced from scratch, and since the job had to be done, someone had seen that it was done properly. Like the weather, in fact…
It was time he moved. The last mail for Earth would be cleared in two hours, and if he missed it Jeannette would not get his letter for almost a week of Earth time. She had already been in suspense long enough.
He pulled the unsealed letter from his pocket, and read it through again for any final amendments.
“Jeannette, my dearest,
“I wish I could tell you where I am, but I’m not allowed to say. It wasn’t my idea, but I’ve been chosen for a special job and I’ve got to make the best of it. I’m in good health, and though I can’t contact you directly, any letters you send to the Box Number I gave you will reach me sooner or later.
“I hated being away on our anniversary, but believe me there was absolutely nothing I could do about it. I hope you received my present safely—and I hope you liked it. It took me a long time to find that necklace, and I won’t tell you how much it cost!
“Do you miss me very badly? God, how I wish I was home again! I know you were hurt and upset when I left, but I want you to trust me and to understand that I couldn’t tell you what was happening. Surely you realize that I want Jonathan Peter as much as you do. Please have faith in me, and
don’t think that it was because of selfishness, or because I don’t love you, that I acted as I did. I had very good reasons, which one day I’ll be able to tell you.
“Above all, don’t worry, and don’t be impatient. You know that I’ll get back as soon as I can. And I promise you this—when I’m home again, we’ll go ahead. I wish I knew how soon that would be!
“I love you, my darling—don’t ever doubt that. This is a tough job, and your faith in me is the one thing that keeps me going.”
He read the letter with great care, trying for the moment to forget all that it meant to him, and to regard it as a message that a complete stranger might have written. Did it give too much away? He did not believe so. It might be indiscreet, but there was nothing in it that revealed his location or the nature of his work.
He sealed the envelope, but put no name or address on it. Then he did something that was, strictly speaking, a direct violation of his oath. He enclosed the letter in another envelope which he addressed, with a covering note, to his lawyer in Washington. “Dear George,” he wrote, “You’ll be surprised to see where I am now. Jeannette doesn’t know, and I don’t want her to worry. So please address the enclosed to her and post it in the nearest mailbox. Treat my present location as absolutely confidential, I’ll explain it all one day.”
George would guess the truth, but he could keep secrets just as well as anyone in Central Intelligence. Sadler could think of no other fool-proof way of getting his letter to Jeannette, and he was prepared to take the slight risk for his peace of mind— and for hers.
He asked the way to the nearest mailbox (they were hard to find in Central City) and slid the letter down the chute. In a couple of hours it would be on the way to Earth; by this time tomorrow, it would have reached Jeannette. He could only hope that she would understand—or, if she could not understand, would suspend judgment until they met again.
There was a paper rack beside the mailbox, and Sadler purchased a copy of the Central News. He still had several hours before the monorail left for the Observatory, and if anything interesting was going on in town the local paper would presumably tell him all about it.
The political news received such little space that Sadler wondered if a mild censorship was in force. No one would have realized that there was a crisis if he went by the headlines alone; it was necessary to search through the paper to find the really significant items. Low down on page two, for example, was a report that a liner from Earth was having quarantine trouble off Mars and was not being allowed to land—while another on Venus was not being allowed to take off. Sadler was fairly sure that the real trouble was political rather than medical; the Federation was simply getting tough.
On page four was a still more thought-provoking piece of news, A party of prospectors had been arrested on some remote asteroid in the vicinity of Jupiter. The charge, it seemed, was a violation of space-safety regulations. Sadler suspected that the charge was phony—and that so were the prospectors. Central Intelligence had probably lost some of its agents.
On the center page of the paper was a rather naive editorial making light of the situation and expressing the confident hope that common sense would prevail. Sadler, who had no illusions about the commonness of common sense, remained skeptical and turned to the local news.
All human communities, wherever they may be in space, follow the same pattern. People were getting born, being cremated (with careful conservation of phosphorus and nitrates), rushing in and out of marriage, moving out of town, suing their neighbors, having parties, holding protest meetings, getting involved in astonishing accidents, writing Letters to the Editor, changing jobs… Yes, it was just like Earth. That was a somewhat depressing thought. Why had Man ever bothered to leave his own world if all his travels and experiences had made so little difference to his fundamental nature? He might just as well have stayed at home, instead of exporting himself and his foibles, at great expense, to another world.
Your job’s making you cynical, Sadler told himself. Let’s see what Central City has in the way of entertainment.
He’d just missed a tennis tournament in Dome Four, which should have been worth watching. It was played, so someone had told him, with a ball of normal size and mass. But the ball was honeycombed with holes, which increased its air-resistance so much that ranges were no greater than on earth. Without some such subterfuge, a good drive would easily span one of the domes. However, the trajectories followed by these doctored balls were most peculiar, and enough to induce a swift nervous breakdown in anyone who had learned to play under normal gravity.
There was a cyclorama in Dome Three, promising a tour of the Amazon Basin (mosquito bites optional), starting at every alternate hour. Having just come from Earth, Sadler felt no desire to return so promptly. Besides, he felt he had already seen an excellent cyclorama display in the thunderstorm that had now passed out of sight. Presumably it had been produced in the same manner, by batteries of wide-angle projectors.
The attraction that finally took his fancy was the swimming pool in Dome Two. It was the star feature of the Central City gymnasium, much frequented by the Observatory staff. One of the occupational risks of life on the Moon was lack of exercise and resultant muscular atrophy. Anyone who stayed away from Earth for more than a few weeks felt the change of weight very severely when he came home. What lured Sadler to the gym, however, was the thought that he could practice some fancy dives that he would never dare risk on Earth, where one fell five meters in the first second and acquired far too much kinetic energy before hitting the water.
Dome Two was on the other side of the city, and as Sadler felt he should save his energy for his destination he took the subway. But he missed the slow-speed section which led one off the continuously moving belt, and was carried willy-nilly on to Dome Three before he could escape. Rather than circle the city again, he retraced the way on the surface, passing through the short connecting tunnel that linked all the domes together at the points where they touched. There were automatic doors here that opened at a touch—and would seal instantly if air-pressure dropped on either side.
Half the Observatory staff seemed to be exercising itself in the gym. Dr. Molton was sculling a rowing machine, one eye fixed anxiously on the indicator that was adding up his strokes. The chief engineer, eyes closed tightly as per the warning instructions, was standing in the center of a ring of ultra-violet tubes which gave out an eerie glare as they replenished his tan. One of the M.D.’s from Surgery was attacking a punchbag with such viciousness that Sadler hoped he would never have to meet him professionally. A tough-looking character who Sadler believed came from Maintenance was trying to see if he could lift a clear ton; even if one allowed mentally for the low gravity, it was still awe-inspiring to watch.
Everybody else was in the swimming pool, and Sadler quickly joined them. He was not sure what he had expected, but somehow he had imagined that swimming on the Moon would differ drastically from the same experience on the Earth. But it was exactly the same, and the only effect of gravity was the abnormal height of the waves, and the slowness with which they moved across the pool.
The diving went well as long as Sadler attempted nothing ambitious. It was wonderful to know just what was going on, and to have time to admire the surroundings during one’s leisurely descent. Then, greatly daring, Sadler tried a somersault from five meters. After all, this was equivalent to less than a meter on Earth…
Unfortunately, he completely misjudged his time of fall, and made half a turn too many—or too few. He landed on his shoulders, and remembered too late just what a crack one could give oneself even from a low height if things went wrong. Limping slightly, and feeling that he had been flayed alive, he crawled out of the pool. As the slow ripples ebbed languidly away, Sadler decided to leave this sort of exhibitionism to younger men.
After all this exertion, it was inevitable that he join Molton and a few of his other acquaintances when they left the gymnasium. Tired but relaxed, and feeling that
he had learned a good deal more about the lunar way of life, Sadler leaned back in his seat as the monocab pulled out of the station and the great doors sealed tight behind them. Blue, cloud-flecked skies gave place to the harsh reality of the lunar night. There was the unchanged Earth, just as he had seen it hours ago. He looked for the blinding star of Nova Draconis, then remembered that in these latitudes it was hidden below the northern edge of the Moon.
The dark domes, which gave so little sign of the life and light they held, sank beneath the horizon. As he watched them go, Sadler was struck by a sudden, somber thought. They had been built to withstand the forces that Nature could bring against them—but how pitiably fragile they would be if ever they faced the fury of Man!
Chapter VII
“I still think,” said Jamieson, as the tractor headed toward the southern wall of Plato, “that there’ll be a hell of a row when the Old Man hears about it.”
“Why should he?” asked Wheeler. “When he gets back, he’ll be too busy to bother about us. And anyway, we’re paying for all the fuel we use. So stop worrying and enjoy yourself. This is our day off, in case you’d forgotten.”
Jamieson did not reply. He was too busy concentrating on the road ahead—if it could be called a road. The only sign that other vehicles had ever been this way were the occasional furrows in the dust. Since these would last for eternity here on the windless Moon, no other signposts were needed, though occasionally one came across unsettling notices that read DANGER —CLEFTS AHEAD! or EMERGENCY OXYGEN—10 KILOMETERS.
There are only two methods of long-range transport on the Moon. The highspeed monorails link the main settlements with a fast, comfortable service running on a regular schedule. But the rail system is very limited, and likely to remain so because of its cost. For unrestricted ranging over the lunar surface, one must fall back on the powerful turbine-driven tractors known as “Caterpillars” or, more briefly, “Cats.” They are, virtually, small spaceships mounted on fat little tires that enable them to go anywhere within reason even over the appallingly jagged surface of the Moon. On smooth terrain they can easily do a hundred kilometers an hour, but normally they are lucky to manage half that speed. The weak gravity, and the caterpillar treads they can lower if necessary, enable them to climb fantastic slopes. In emergencies, they have been known to haul themselves up vertical cliffs with their built-in winches. One can live in the larger models for weeks at a time without undue hardship, and all the detailed exploration of the Moon has been carried out by prospectors using these tough little vehicles.
