It was a well.

Henry Bedrosian and Christopher Luden bent over the lip' peering down into the jet darkness. Their balloon-tired motorcycle lay forgotten on the talcum sand, fine pink sand that stretched endlessly ,,away to the flat horizon, borrowing its color from the sky. The sky was the color of blood. It might have been a flaming Kansas sunset, but the tiny sun was still at the zenith. The translucent hewn stone of the well-mouth stood like a blasphemy in the poisonous wilderness that was Mars.

It stood four feet above the sand, roughly circular' perhaps three yards across. The weathered stones were upright blocks, a foot tall by five inches wide by perhaps a foot thick. Whatever the material of those stones' they seemed to glow with a faintly blue inner light.

"It's so human!" said Henry Bedrosian. His voice held a touch of bewildered frustration' echoed by his dark' chisel-nosed face.

Chris Luden knew what he meant. "It's natural. A well's like a lever or a wheel. There aren't many changes you can make' because it's too simple. Did you notice the shape of the bricks?"

"Yes. Odd. But they could still be man made."

"In this air? Breathing nitric oxide' drinking red fuming nitric acid? But-" Chris drew a deep breath. "Why complain? It's life, Harry! We've discovered intelligent life!"

"We've got to tell Abe."

"Right."

But it was a long moment before either moved. They stood leaning over the well' vivid green pressure suits against pink sand and dark red horizon' peering down into the blur of darkness at the bottom Then they turned and mounted the Marsmobile.

The landing vehicle stood like an upright steel ballpoint pen. Its

bottom half was three spreading legs, a restarting solid rocket, and a spacious cargo hold' two-thirds empty now. The upper half was the return-to-orbit stage. Far away across the crescent dunes was a white patch, the jettisoned drag chute.

The Marsmobile, a glorified two-seater motorcycle with big round tires and a number of special modifications, putt-putted up to a landing leg and stopped. Henry got off and climbed to the cabin to call Abe Cooper in the orbiter. Chris Luden mounted to the cargo hold and rummaged through a disorganized hash of necessities until he had a long coil of thin line, a metal bucket' and a heavy rock hammer all treated to resist the corrosive atmosphere. He dropped the objects next to the Marmobile and climbed down. "Now we'll see," h e told himself.

Henry descended the ladder. "Abe's having kittens"' he reported. "1Ie says if we don't call him every five minutes he'll come down after us. He wants to know' how old is the well?"

"So do I." Chris brandished the hammer. "We'll knock a chip off and analyze it. Let's go."

The well was a mile and a half from the ship' and not of a conspicuous color. Probably they would have lost it if they hadn't left a flag to mark it.

"Let's see how deep it is first," said Luden. He put the hammer in the bucket for a weight' tied a line to the handle and let it fall. In the eery silence of the Martian desert they waited, listening ... The rope was nearly gone when the bucket struck something. In a moment the ghost of a splash came floating up from the depths. Henry marked the line so they could measure how deep it had gone. It looked about three hundred feet. They hauled it up.

The bucket was half full of a cloudy' slightly oily fluid.

Chris handed it to his partner. "Harry, you want to take this back and analyze it?"

Henry's dark face grinned around the pointed beard. "I'll match you for it. We both know what it's gonna be."

"Sure, but it has to be done. Even." They matched fingers. Henry lost. He rode back to the ship' the bucket dangling from one hand, fluid slopping over the edge.

The stone which formed the well might have been quartz, or even

some kind of unveined marble. It had been too badly weathered, too finely scored and polished and etched by the patient sand grains' to tell what it was. Chris Luden picked a likely looking block and brought the hammer down hard on what seemed to be a crack. He did it three times.

The hammer was ruined.

Luden shifted the hammer this way and that to examine the uneven, dulled edge and flattened corners. His blue eyes held a puzzled look. He knew the government might have quibbled about the weight of a tool for the Mars Project, but never the cost or quality. Here on Mars that hammer was worth tens of thousands of dollars It must be made of some hard' durable steel alloy. Then

He cocked his head in his helmet' tasting a strange idea ...

"Harry!"

"Yeah?"

"How you doing?"

"I'm just coming in the airlock. Give me five minutes to find out that this stuff is nitric acid."

"Okay, but do me a favor. Have you got your ring?"

"The diamond horseshoe? Sure."

"Bring it back with you, outside your suit. Outside, that is."

"Now wait a minute, Chris. That's a valuable ring. Why not use our own?"

"I should have thought of that! I'll just take off my pressure suit and-Uh! Can't seem to get my helmet unfastened-"

"Stop! Stop! I get the point." There was a click as Henry's radio went off.

Luden sat down to wait.

The sun was sliding toward the horizon. They had landed shortly before sunset yesterday' so they knew how suddenly the desert could turn from pink to midnight black, and how little light the insignificant moons gave. But sundown was four hours away.

The dunes all faced the same way' perfect crescents' as regular as if hand-made. Something must shape the winds here' causing them to blow always in one direction' like Earth's trade winds. And the dune would crawl across the sands, slower than snails, following the winds.

How old were the stones against his back? If they were really-a

strange and silly thought' but Chris wouldn't have volunteered for lie Mars Project if he were not half a romantic - if they were really diamond, they must be terribly old, to be so worn by mere sand. Far older than the pyramids, and revered ancestor to the Sphinx. Maybe the race that carved those stones had since perished. Science-fiction writers often assumed an extinct Martian race. Why' perhaps the ,,ell had originally held water

"Hello, Chris?"

"Here."

"It's dirty nitric acid, not too strong. Next time you'll believe me."

"Harry, they didn't send us here to make astute guesses. They did ,ill the guessing when they built the ship. We came to find out for ,.,lire, right? Right."

"See you in ten minutes." Click.

Luden let his eyes drift back across the desert. It was a moment before he realized what had caught his eye. One of the dunes was irregular The curves were wrong, asymmetrical. The normal crescent ,,,.ad left one sprawling' trailing arm. It stood out like a pear in a line 4 apples.

He had ten minutes' and the dune wasn't far. Luden got up and started walking.

He stood under the dune and looked back. The well was clearly The distance was even shorter than he had thought. He had been deceived by the nearness of the horizon.

The lip of the dune was some fourteen feet high.

What had distorted it? An upthrusting spire of rock' perhaps' not quite high enough to show through the sand. They could find it with the sonar later.

It had to be under the one sprawling' twisted arm of sand.

"Chris! Where the hell are you? Chris?"

Chris jumped. He'd forgotten Henry. "Look due south of the well a -id you'll see me."

"Why don't you stay where you're put' you idiot? I thought you'd been buried by a sandstorm."

11 Sorry' Harry. I got interested in something." Chris Luden was now standing on the twisted arm of sand. He sounded preoccupied. "Try scratching the blocks of the well with your ring."

"That's an odd thought," Henry laughed.

"Do it."

Silence. Luden felt the wind, looked down at the sand' tried to imagine what obstruction had dropped it here. Something not necessarily very large. It would not be beneath the dune; it would be on the windward side ... at the beginning of the arch ... there.

"I scratched it' Chris. There's a scratch all right. So that effectively takes-Ooops. Aaargh! Chris' you're doomed! Only death can save you from my wrath!"

"Why are you irritated with-"

"My diamond! It's ruined!"

"Relax. You could replace it a million times over with just one block from the well."

"Say, that's true. But we'll need the laser to cut it loose. They must have used diamond dust for the cement' too. And the fuel to get it back-"

"Harry, do me a favor. Bring-"

"That last favor cost me a three-thousand-dollar ring."

"Bring the Marsmobile out here. I want to do some digging."

"Be right there."

A minute later Henry stopped the machine alongside Chris's green suit. His smile showed that the scratches on his ring had not permanently scarred his psyche. "Where do we dig?"

"Right where I'm standing."

The Marsmobile was equipped with two down-thrusting compressed-air jets for getting over steep obstructions. A large tank under the vehicle's belly held the heavily compressed air' compressed directly from the thin Martian atmosphere by the motor. Henry turned on the jets and hovered over the spot where Chris had been standing, shifting his weight to keep the machine in place. Sand sprayed out in sheets. Chris ran to get out from under, and Henry grinned and doubled the thrust to send the fine grains showering over him. In half a minute the pressure became too low. Henry had to land. The Marsmobile shuddered and vibrated as its motor struggled to refill the pressure chamber.

"I hate to ask," said Henry, "but what's the point of all this?"

"There's something solid down there. I want to expose it."

"Okay, if you're sure we're in the right place. We've got six months of time to waste."

They wasted a few minutes silently watching the Marsmobile fill its pressure tank.

"Hey," said Henry. "You think we could stake a claim on this diamond mine?"

Chris Luden, sitting on the steep side of the dune, thoughtfully scratched the side of his helmet. "Why not? We haven't seen any live Martians, and it's for sure that nobody else has a claim. Sure, we'll file our claim; the worst they can do is disallow it."

"One thing. I didn't mention it before because I wanted you to see for yourself, but the heck with it. One of those blocks is covered solid with deep scratches."

"They all are."

"Not like these. These are deep' and they're all at forty-five degree angles, unless my imagination is fooling me. They're too fine to be ,tire, but I think it's some kind of writing."

And without waiting for an answer' Henry took off on the air jets. He was good at it. He was like a ballet dancer. You could see Henry shifting weight, but the scooter never seemed to move.

Something was emerging from the sand. Something not a rock.

Something like a piece of modern metal sculpture' with no use and no meaning but with a weird beauty nonetheless. Something that had been a machine and was now-nothing.

Henry Bedrosian balanced above the conical pit his jets had dug. The artifact was almost clear now. Something else showed beside it.

A mummy.

The Marsmobile settled on the last of its air. Chris plunged down the side of the pit as Henry climbed off.

The mummy was humanoid, about four feet long, with long Arms, enormous fragile tapered fingers, and a traditionally oversized skull. No fine detail was visible; it had all been worn away. Chris couldn't even be sure how many fingers the-hominid-had had. One hand still held two; the other only one, plus a flattened opposable thumb. No toes showed on the feet. The thing lay face down.

'1 'he artifact, now uncovered, showed more detail. Yet the detail

had no meaning. Thick bent metal bars, thin twisted wires' two enormous crumpled circles with something rotted clinging to what lead been their rims-and then Henry's imagination clicked, the same visual knack that had gotten him A's in topology, and he said, "It's a bicycle."

"You've lost your mind."

"No, look. The wheels are too big, and-"

It was a fantastically distorted bicycle' with wheels eight feet across, a low, dwarf-sized saddle' and a system of gears to replace the chain. The gear ratio was very low. The saddle was almost against the rear wheel, and a tiller bar, now bent to scrap' had been fixed to the hub of the front wheel. Something had crumpled the bicycle like a crush-proof cigarette pack in a strong man's hand, and then nitric acid rust had done its worst to the metal.

"Okay' it's a bicycle," said Chris. "It's a Salvador Dali bicycle' but still a bicycle. They must have been a lot like us, hmmm? Bicycles, stone wells, writing-"

"Clothing."

"Where?"

"It must have been there. He's less worn around the torso' see.' You can see the wrinkles in his skin. He must have been protected until his clothes rotted away."

"Maybe. He kind of ruins our lost race theory, doesn't he? He couldn't possibly be more than a couple of thousand years old. Hundreds would be more like it."

"Then he drank nitric acid after all. Well, that blows our diamond mine, partner. He's got to have living relatives."

"We can't count on their being too much like us. These things we've found-clothing, writing, wells-they're all things any intelligent being might be forced to invent. And parallel evolution might explain the biped shape."

"Parallel evolution?" Henry repeated.

"Like the eye of an octopus. It's nearly identical in structure to a human eye. Yet an octopus isn't remotely human. Most marsupials, you can't tell them from their mammal counterparts. Well' let's try to pick him up."

Any archaeologist would have shot them down in cold blood.

The mummy was as light and dry as cork' and showed no tendency to come apart in their hands. They strapped him gently over the luggage box and climbed on themselves. Chris drove back slowly and carefully.

Chris stood on the first rung of the ladder' adjusting the mummy's balance on his left shoulder. "We'll have to spray him with plastic before takeoff"' he said. "Do we have any plastic spray?"

"I don't remember any. We'd better take lots of pictures in case it does come apart."

"Right. There's a camera in the cabin." Chris started up' and Henry followed. They got the relic to the airlock without mishap.

"I've been thinking"' said Henry. "That nitric acid wasn't dilute, exactly, but there was water in it. Maybe this guy's chemistry can extract the water from nitric acid."

"Good thought."

They put the mummy gently on a pile of blankets and began searching for the camera. After five frustrating minutes Chris deliberately banged his head against a wall. "I took it out to catch the sunset last night. It's in the cargo hold."

"Go get it."

Henry stood in the airlock, watching as Chris went down the ladder. After a moment in the cargo space Chris started up with the camera strap over his shoulder.

"I've been thinking too," said Chris, his voice seemingly dissociated from his climbing figure. "Diamond can't be that plentiful here, and carving it into blocks must have been real hard labor. Why diamond? And why write on a well?"

"Religious reasons? Maybe they worship water."

"That's what I was thinking."

"Of course you were. That plot's as old as Lowell."

Chris had reached the top. They squeezed into the airlock and waited for it to cycle.

The door opened. Both men had their helmets off by this time, and they both smelled it at once. Something chemical' something strong

Thick' greasy smoke was pouring up from the ancient corpse.

Henry reacted first. He sprang for the double boiler in the small

kitchen corner. The bottom half was still full of water; he snatched it up and threw the water over the smoldering Martian mummy while with his other hand he turned on the water faucet to get more.

The mummy went off like a napalm bomb.

Henry leaped away from the exploding flames and his head rammed something flat and very hard. He went down with his eyes full of leaping light. Immediately he sat up, knowing that something urgently needed doing but unable to remember what. He saw Chris, still in vacuum suit except for the helmet, run through the multicolored flames' pick the mummy up by the ankles and throw it into the airlock. Chris hit the "Cycle" button. The inner door swung shut.

Then Chris was bending over him. "Where does it hurt, Harry? Can you talk? Can you move?"

Henry sat up again. "I'm okay."

Chris expelled a gusty breath. Then he began to laugh.

Henry stood up a little shakily. His head ached. The fumes in the cabin weren't intolerable, and already the air plant was whining its eagerness to make the air pure and scentless. Red smoke from the open outer airlock door blew past a porthole, dying away. "What made him explode?" he wondered.

"The water," said Chris Luden. "What a wild chemistry he must have! I want to be there when we meet a live one."

"But what about the well? We know he used water."

"Yes he did. He sure as hell did. And did you know that an octopus eye is identical to a human eye?"

"Sure. But a well is a well, isn't it?"

"Not when it's a crematorium' Harry. What else could it be? There's no fire on Mars, but water must dissolve a body completely. And wouldn't I like to know what the morticians charge their customers for those cut diamond building blocks! The hardest substance known to Man or Martian! An everlasting monument to the dear departed!"
