The radio crackled back at him. “We got a schedule to meet, egghead. Now you get those transponders planted, then you get your heinie back here mucho pronto.”
Bowman hadn’t said “Over,” but Mather was about to confirm and sign off when the crew chief continued with, “And you come home by the seabed. You wreck that jeep, and you’ll be going back Earthside on the next rocket, with a forfeiture of all pay and benefits!”
“Roger, over and out,” Mather said. He put down the radio and steered the vehicle through a gateway of bone pillars carved in twin spirals that led to a small plaza surrounded by two-story white buildings, their walls pierced by narrow doors and slits for windows.
The Martians had been light-boned and graceful, brown-skinned and golden-eyed, though they had often worn masks when they went out—silver or blue for the men, crimson for the women, gold for the children. Back on Earth, he had seen the long-distance images recorded by the earliest expeditions—the ones that had failed, for reasons still unknown. There were no close-up, postcontact likenesses of Martians because between the third and fourth landings, Terran diseases to which they had no resistance had killed off almost all of them in a few weeks. Their flesh had dried to leaves and their bones had become sticks; the floors of their homes were littered with the stuff.
Mather would have loved to meet a Martian, though he knew they could be strange. Telepathic was the prevailing opinion among academics, though with brains that worked at a sideways tangent to what humans meant when they said, “Common sense.”
You still heard tales of surviving Martians, spotted at a distance in remote places—such as the blue hills behind him. That had been another reason Mather had come that way, just in case.
He sat in the jeep and took a long, slow look at as much of the town as he could see from here. “Get a good overview,” his graduate-thesis advisor used to say, “before you plunge into the detail. That way the details will form themselves into a pattern sooner and you may save yourself from running up a lot of blind alleys.”
The plaza held only one object of note. At the center of the open space that surrounded him was a substantial circular structure, four ascending, concentric rings of white material that would probably turn out to be bone—there was a reason why the dead town was called “the bone city.”
Mather could see a bronze pipe standing up from the smallest, highest circle. From it would have flowed water to fill the first round of the four, to trickle over the sides and fill the others in turn. Of course, not a drop of liquid had dampened the object in millennia: this part of Mars was believed to have been abandoned tens of centuries ago, after the seas had vanished and the soft rains that had gently sculpted the hills ceased to come over the green water.
Having finished his survey, Mather climbed out of the jeep, hooked the radio to his belt, and approached the nearest building. Its door was ajar, but he had to push it all the way open to squeeze through the narrow entry. He found himself in a circular foyer, its bone walls decorated with lines of copper—once gleaming, now a dull green—that had been inset into incisions in the white hardness.
Some of the lines were curved, some straight. They met at odd angles and somehow contrived to draw Mather’s gaze into what seemed to be three-dimensional shapes. It seemed to him that the silence in the dead town had managed to deepen. Then, as he continued to stare, trying to make sense of the forms emerging from the matrix, the lines moved of their own accord. He experienced a growing vertigo. One moment, he was looking into an infinite distance; the next, he was about to fall into it.
He clapped his hands to his eyes and held them there while he slowly counted to ten. When he took them away, he was looking again at lines of verdigrised copper set into bone. But immediately they started their pull. He dropped his gaze to the floor, saw a spiral mosaic of gold and silver tiles, faded and half-obscured by dust that had drifted through the doorway. At least it did not move.
The radio hissed and squawked again. “Base to Mather,” said Bowman’s voice, “we’re not seeing any transponder signals.”
He went outside. “I’m in the town, just scoping for the best sites,” he said.
The backseats of the jeep had been taken out to make room for a large wooden box with a hinged lid. Inside, nestled in packing straw, were dozens of small, black oblongs, each one a radio transponder with a telescoping steel antenna that could be pulled up from its top and a red on-off switch.
Mather’s job was to place the devices in a rough grid. As he positioned each one, he was to throw its switch to on. The transponders would broadcast signals that would delineate the layout of the ancient town to the electronic brain of a huge tracked machine that was even now being slowly hauled from the base camp down to the dry seabed. Tonight, it would be eased down to the seabed, there to be loaded onto a multiwheeled transporter. Tomorrow, it would creep the rest of the way to the bone town, to be off-loaded at the base of a sloping ramp topped by a set of stairs from which, presumably, the ancient Martians had once launched their shining boats.
The leviathan would trundle up into the town, deploy its hydraulic grapples, and begin stuffing the bone city, piece by piece, into its mechanical maw. It would grind up the town, house by house, separating metal and stone from the ossiferous material that the Martians had built the place from. The valueless stone would be spat out, the metal compacted and excreted like cubic droppings.
The metal was valuable, but it was the bone that really mattered. It would be pulverized, sacked, and stacked on a detachable trailer that rolled along behind the behemoth. As a trailer was filled, it would be detached and another put in its place. Then the loaded trailer would be hooked to a tractor, and the eight-wheeler would head off across the dry sea until it met the Martian road-and-canal network. Then it would go to one of the newly built Earthman towns that were surrounded by farms whose soil, even after lying fallow for thousands of years, was not all it might be.
The ground bones of Martian cities would fertilize the crops that would feed the tens of thousands of Earthmen arriving each month as the silver-rocket armada continued to cross the black gulf between the worlds.
Mather was one of the most recent arrivals. He had been unable to secure funding to come to Mars as an archaeologist. The new old world needed brawny pioneers, not pointy-headed academics, he was told. Archaeologists objected to the destruction of the ancient Martian cities, so the company was being careful not to let any of them anywhere near them.
So Mather had concocted a résumé that should not have withstood even the most cursory scrutiny, but New Ares Mining Corporation had lucrative contracts to fulfill and was desperate for men to mine the bone cities. Mather was on the next rocket out.
The trip was long and the quarters close. The men he would be working with soon deduced that Fred Mather had not come, as they had, from the coal mines of Kentucky or the oil leases of west Texas. His hands were too soft and his neck not rough enough. The crew chief, Red Bowman, a veteran of the Alaska gold fields, marked him down as a city-boy tenderfoot on a job that had no slack to cut for greenhorns.
Mather worked quickly, quartering the town on foot, placing the transponders according to a rough map made from an aerial photograph snapped by a New Ares rocket. Two hours after he began, he threw the switch on the last device, then walked back to where he had left the jeep.
He lifted the hood, removed the cover of the carburetor, and dropped a pinch of Martian grit into its barrel. Then he radioed base to say that the vehicle wasn’t running right—he suspected dirt in the carburetor or fuel line—so he would stay the night in the town and repair the faulty part in the morning.
“I wouldn’t want to risk overturning the jeep coming home in the dark,” he said. “Those roads can ice up pretty bad, I hear.”
