that he kept the curtains closed, and tended to stay on the side of his room away from the window. In the mornings he dressed and left the room quickly, and attended orientation meetings run by Adrienne, which were joined by a score or so of new arrivals. After lunching with some of them, he spent his afternoons touring the town, working earnestly on his walking skills. One night he thought to send a coded report off to Fort: On Mars, going through orientation. Sheffield is a nice town. My room has a view. There was no reply.
Adrienne’s orientation took them to a number of Praxis buildings, both in Sheffield and up the east rim, to meet people in the transnational’s Martian operations. Praxis had much more of a presence on Mars than it did in America. During Art’s afternoon walks he tried to gauge the relative strengths of the transnationals, just by the little plates on the sides of the buildings. All the biggest transnats were there—Armscor, Subarashii, Oroco, Mitsubishi, The Seven Swedes, Shellalco, Gentine, and so on—each occupying a complex of buildings, or even entire neighbourhoods of the town. Clearly they were all there because of the new elevator, which had made Sheffield once again the most important city on the planet. They were pouring money into the town, building submartian subdivisions, and even entire tent suburbs. The sheer wealth of the transnats was obvious in all the construction—and also, Art thought, in the way people moved—there were a lot of people bouncing around the streets just as clumsily as he was, newcomer businessmen or mining engineers or the like, concentrating with furrowed brow on the act of walking. It was no great trick to pick out the tall young natives, with their catlike co-ordination; but they were in a distinct minority in Sheffield, and Art wondered if that were true everywhere on Mars.
As for architecture, space under the tent was at a premium, and so the completed buildings were bulky, often cubical, occupying their lots right out to the street and right up to the tent. When all the construction was finished there would only be a network of ten triangular plazas, and the wide boulevards, and the curving park along the rim, to keep the town from being a continuous mass of squat skyscrapers, faces with polished stone of various shades of red. It was a city built for business.
And it looked to Art like Praxis was going to get a good share of that business. Subarashii was the general contractor for the elevator, but Praxis was supplying the software as they had for the first elevator, and also some of the cars, and part of the security system. All these allocations, he learned, had been made by a committee called the United Nations Transitional Authority, supposedly part of the UN, but controlled by the transnats; and Praxis had been as aggressive on this committee as any of the others. William Fort may have been interested in bio-infrastructure, but the ordinary kind was obviously not outside Praxis’s field of operations; there were Praxis divisions building water supply systems, train pistes, canyon towns, wind power generators, and areothermal plants. The latter two were widely regarded as marginal endeavours, as the new orbiting solar collectors and a fusion plant in Xanthe were turning out so well, not to mention the older generation of integral fast reactors; but local energy sources were the speciality of the Praxis subsidiary Power From Below, and so that was what they did, working hard in the outback.
Praxis’s local salvage subsidiary, the Martian equivalent of Dumpmines, was called Ouroborous, and like Power From Below it was also fairly small. In truth, as the Ouroborous people were quick to tell Art when they met one morning, there was not a large rubbish output on Mars; almost everything was recycled or put to use in creating agricultural soil, so each settlement’s dump was really more of a holding facility for miscellaneous materials, awaiting their particular use. Ouroborous therefore got its business by finding and collecting the garbage or sewage that was somehow recalcitrant—toxic, or orphaned, or simply inconvenient—and then finding ways to turn it to use.
The Ouroborous team in Sheffield occupied one floor of Praxis’s downtown skyscraper. The company had got its start excavating the ruins of the old town, before the ruins had been so unceremoniously shoved over the side. A man named Zafir headed the fallen cable salvage project, and he and Adrienne accompanied Art to the train station, where they got on a local train and took a short ride around to the east rim, to a line of suburb tents. One of the tents was the Ouroborous storage facility, and just outside it, among many other vehicles, was a truly gigantic mobile processing factory, called the Beast. The Beast made a SuperRathje look like a compact car—it was a building rather than a vehicle, and almost entirely robotic. Another Beast was already out processing the cable in west Tharsis, and Art was slated to go out and make an onsite inspection of it. So Zafir and a couple of technicians showed him around the inside of the training vehicle, ending up in a wide compartment on the top floor, where there were living quarters for any humans that might be visiting.
Zafir was enthusiastic about what the Beast out on west Tharsis had found. “Of course just recovering the carbon filament and the diamond gel helixes gives us a basic income stream,” he said. “And we are doing well with some brecciated exotics metamorphosed in the final hemisphere of the fall. But what you’ll be interested in are the buckyballs and buckytubes. Temperatures and pressures in the west Tharsis zone turned out to be similar to those used in the arc-reactor-synthesis method of making fullerenes, and so there is a hundred-kilometre stretch out there where carbon on the bottom side of the cable consists of buckyballs—mostly sixties, but also some thirties, and a variety of superbuckies and buckytubes of all lengths.” And some of the superbuckies had formed with other elements trapped inside their carbon cage. These full fullerenes were useful in composite manufacturing, but very expensive to make in the lab because of the high amounts of energy required. So they were a nice find. “And it’s sorting out the various superbuckies where your ion chromatography will come in.”
“So I understand,” Art said. He had done work with ion chromatography during analyses in Georgia, and this was his ostensible reason for being sent into the outback. So over the next few days Zafir and some Beast technicians trained Art in dealing with the Beast, and after these sessions they had dinner together at a small restaurant in the suburb tent on the east rim. After sunset they had a great view of Sheffield, some thirty kilometres around the curve of the rim, glowing in the twilight like a lamp perched on the black abyss.
As they ate and drank, the conversation seldom turned to the matter of Art’s project, and considering it, Art decided that this was probably a deliberate courtesy on his colleagues’ part. The Beast was fully self-operating, and though there were some problems to be solved in sorting out the recently discovered full fullerenes, there must have been local ion chromatographers who could have done the job. So there was no obvious reason why Praxis should have sent Art up from Earth to do it, and there had to be something more to his story. And so the group avoided the topic, saving Art the embarrassment of lies, or awkward shrugs, or an explicit appeal to confidentiality.
Art would have been uncomfortable with any of these dodges, and so he appreciated their tact. But it put a certain distance in their conversations. And he seldom saw the other Praxis newcomers, outside of orientation meetings; and he didn’t know anyone else in town, or elsewhere on the planet. So he was a little lonely, and the days passed in an increasing sense of uneasiness, even oppression. He kept the curtains closed on his window view, and ate in restaurants away from the rim. It began to feel a bit too much like the weeks on the Ganesh, which he now understood to have been a miserable time. Sometimes he had to fend off the feeling that it had been a mistake to come.
And so after their last orientation lecture, at a reception luncheon in the Praxis building, he drank more than was his custom, and took a few inhalations from a tall canister of nitrous oxide. Inhalation of recreational drugs was a local custom, apparently fairly big among Martian construction workers, he had been told, and there were even little canisters of various gases for sale from dispensers in some public men’s rooms. Certainly the nitrous added a certain extra bubbly quality to the champagne; it was a nice combination, like peanuts and beer, or ice cream and apple pie.
Afterward he walked down the streets of Sheffield bouncing erratically, feeling the nitrous champagne as a kind of anti-gravitational effect, which, added to the Martian baseline, made him feel altogether too light. Technically he weighed about forty kilos, but as he walked along it felt more like five. Very strange, even unpleasant. Like walking on buttered glass.
He nearly ran into a young man, slightly taller than him—a black-haired
