MAN OF PARTS

There wasn't a trace of amnesia or confusion when Major Hugh Savold, of the Fourth Earth Expedition against Vega, opened his eyes in the hospital. He knew exactly who he was, where he was, and how he had gotten there.

His name was Gam Nex Biad.

He was a native of the planet named Dorfel.

He had been killed in a mining accident far underground. The answers were preposterous and they terrified Major Savold. Had he gone insane? He must have, for his arms were pinned tight in a restraining sheet. And his mouth was full of bits of rock.

Savold screamed and wrenched around on the flat, comfortable boulder on which he had been nibbling. He spat out the rock fragments that tasted—nutritious.

Shaking, Savold recoiled from something even more frightful than the wrong name, wrong birthplace, wrong accident, and shockingly wrong food.

A living awl was watching him solicitously. It was as tall as himself, had a pointed spiral drill for a head, three knee-action arms ending in horn spades, two below them with numerous sensitive cilia, a row of socketed bulbs down its front, and it stood on a nervously bouncing bedspring of a leg. Savold was revolted and tense with panic. He had never in his life seen a creature like this. It was Surgeon Trink, whom he had known since infancy.

"Do not be distressed," glowed the surgeon's kindly lights. "You are everything you think you are."

"But that's impossible! I'm an Earthman and my name is Major Hugh Savold!"

"Of course."

"Then I can't be Gam Nex Biad, a native of Dorfel!"

"But you are."

"I'm not!" shouted Savold. "I was in a one-man space scout. I sneaked past the Vegan cordon and dropped the spore-bomb, the only one that ever got through. The Vegans burned my fuel and engine sections full of holes. I escaped, but I couldn't make it back to Earth. I found a planet that was pockmarked worse than our moon. I was afraid it had no atmosphere, but it did. I crash-landed." He shuddered. "It was more of a crash than a landing."

Surgeon Trink brightened joyfully. "Excellent! There seems to be no impairment of memory at all."

"No?" Savold yelled in terror. "Then how is it I remember being killed in a mining accident? I was drilling through good hard mineral ore, spinning at a fine rate, my head soothingly warm as it gouged into the tasty rock, my spades pushing back the crushed ore, and I crashed right out into a fault . . ."

"Soft shale," the surgeon explained, dimming with sympathy. "You were spinning too fast to sense the difference in density ahead of you. It was an unfortunate accident. We were all very sad."

"And I was killed," said Savold, horrified. "Twice!"

"Oh, no. Only once. You were badly damaged when your machine crashed, but you were not killed. We were able to repair you."

Savold felt fear swarm through him, driving his ghastly thoughts into a quaking corner. He looked down at his body, knowing he couldn't see it, that it was wrapped tightly in a long sheet. He had never seen material like this.

He recognized it instantly as asbestos cloth.

There was a row of holes down the front. Savold screamed in horror. The socketed bulbs lit up in a deafening glare.

"Please don't be afraid!" The surgeon bounced over concernedly, broke open a large mica capsule, and splashed its contents on Savold's head and face. "I know it's a shock, but there's no cause for alarm. You're not in danger, I assure you."

Savold found himself quieting down, his panic diminishing. No, it wasn't the surgeon's gentle, reassuring glow that was responsible. It was the liquid he was covered with. A sedative of some sort, it eased the constriction of his brain, relaxed his facial muscles, dribbled comfortingly into his mouth. Half of him recognized the heavy odor and the other half identified the taste.

It was lubricating oil.

As a lubricant, it soothed him. But it was also a coolant, for it cooled off his fright and disgust and let him think again. "Better?" asked Surgeon Trink hopefully.

"Yes, I'm calmer now," Savold said, and noted first that his voice sounded quieter, and second that it wasn't his voice—he was communicating by glows and blinks of his row of bulbs, which, as he talked, gave off a cold light like that of fireflies. "I think I can figure it out. I'm Major Hugh Savold. I crashed and was injured. You gave me the body of a . . ." he thought about the name and realized that he didn't know it, yet he found it immediately ". . . a Dorfellow, didn't you?"

"Not the whole body," the surgeon replied, glimmering with confidence again as his bedside manner returned. "Just the parts that were in need of replacement."

Savold was revolted, but the sedative effect of the lubricating oil kept his feelings under control. He tried to nod in understanding. He couldn't. Either he had an unbelievably stiff neck . . . or no neck whatever.

"Something like our bone, limb, and organ banks," he said.. "How much of me is Gam Nex Biad?"

"Quite a lot, I'm afraid." The surgeon listed the parts, which came through to Savold as if he were listening to a simultaneous translation: from Surgeon Trink to Gam Nex Biad to him. They were all equivalents, of course, but they amounted to a large portion of his brain, skull, chest, internal and reproductive organs, mid-section, and legs.

"Then what's left of me?" Savold cried in dismay.

"Why, part of your brain—a very considerable part, I'm proud to say. Oh, and your arms. Some things weren't badly injured, but it seemed better to make substitutions. The digestive and circulatory system, for instance. Yours were adapted to foods and fluids that aren't available on Dorfel. Now you can get your sustenance directly from the minerals and metals of the planet, just as we do. If I hadn't, your life would have been saved, but you would have starved to death."

"Let me up," said Savold in alarm. "I want to see what I look like." The surgeon looked worried again. He used another capsule of oil on Savold before removing the sheet.

Savold stared down at himself and felt revulsion trying to rise. But there was nowhere for it to go and it couldn't have gotten past the oil if there had been. He swayed sickly on his bedspring leg, petrified at the sight of himself.

He looked quite handsome, he had to admit—Gam Nex Biad had always been considered one of the most crashing bores on Dorfel, capable of taking an enormous leap on his magnificently wiry leg, landing exactly on the point of his head with a swift spin that would bury him out of sight within instants in even the hardest rock. His knee-action arms were splendidly flinty; he knew they had been repaired with some other miner's remains, and they could whirl him through a self-drilled tunnel with wonderful speed, while the spade hands could shovel back ore as fast as he could dig it out. He was as good as new . . . except for the disgustingly soft, purposeless arms.

The knowledge of function and custom was there, and the reaction to the human arms, and they made explanation unnecessary, just as understanding of the firefly language had been there without his awareness. But the emotions were Savold's and they drove him to say fiercely, "You didn't have to change me altogether. You could have just saved my life so I could fix my ship and get back ..." He paused abruptly and would have gasped if he had been able to. "Good Lord! Earth Command doesn't even know I got the bomb through! If they act fast, they can land without a bit of opposition!" He spread all his arms—the two human ones, the three with knee-action and spades, the two with the sensitive cilia—and stared at them bleakly. "And I have a girl back on Earth . . ." Surgeon Trink glowed sympathetically and flashed with pride. "Your mission seems important somehow, though its meaning escapes me. However, we have repaired your machine . . ."

"You have?" Savold interrupted eagerly.

"Indeed, yes. It should work better than before." The surgeon flickered modestly. "We do have some engineering skill, you know."

The Gam Nex Biad of Savold did know. There were the underground ore smelters and the oil refineries and the giant metal awls that drilled out rock food for the manufacturing centers, where miners alone could not keep up with the demand, and the communicators that sent their signals clear around the planet through the substrata of rock, and more, much more. This, insisted Gam Nex Biad proudly, was a civilization, and Major Hugh Savold, sharing his knowledge, had to admit that it certainly was.

"I can take right off, then?" Savold flared excitedly.

"There is a problem first," glowed the surgeon in some doubt. "You mention a 'girl' on this place you call 'Earth.' I gather it is a person of the opposite sex."

"As opposite as anybody can get. Or was," Savold added moodily. "But we have limb and organ banks back on Earth. The doctors there can do a repair job. It's a damned big one, I know, but they can handle it. I'm not so sure I like carrying Gam Nex Biad around with me for life, though. Maybe they can take him out and . . ."

"Please," Surgeon Trink cut in with anxious blinkings. "There is a matter to be settled. When you refer to the girl, you do not specify that she is your mate. You have not been selected for each other yet?"

"Selected?" repeated Savold blankly, but Gam Nex Biad supplied the answer—the equivalent of marriage, the mates chosen by experts on genetics, the choice being determined by desired transmittable aptitudes. "No, we were just going together. We were not mates, but we intended to be as soon as I got back. That's the other reason I have to return in a hurry. I appreciate all you've done, but I really must . .

."

"Wait," the surgeon ordered.

He drew an asbestos curtain that covered part of a wall. Savold saw an opening in the rock of the hospital, a hole-door through which bounced half a dozen little Dorfellows and one big one . . . straight at him. He felt what would have been his heart leap into what would have been his chest if he had had either. But he couldn't even get angry or shocked or nauseated; the lubricating oil cooled off all his emotions.

The little creatures were all afire with childish joy. The big one sparkled happily.

"Father!" blinked the children blindingly.

"Mate!" added Prad Fim Biad in a delighted exclamation point.

"You see," said the surgeon to Savold, who was shrinking back, "you already have a mate and a family."

It was only natural that a board of surgeons should have tried to cope with Savold's violent reaction. He had fought furiously against being saddled with an alien family. Even constant saturation with lubricating oil couldn't keep that rebellion from boiling over.

On Earth, of course, he would have been given immediate psychotherapy, but there wasn't anything of the sort here. Dorfellows were too granitic physically and psychologically to need medical or psychiatric doctors. A job well done and a family well raised—that was the extent of their emotionalism. Savold's feelings, rage and resentment and a violent desire to escape, were completely beyond their understanding. He discovered that as he angrily watched the glittering debate. The board quickly determined that Surgeon Trink had been correct in adapting Savold to the Dorfel way of life. Savold objected that the adaptation need not have been so thorough, but he had to admit that, since they couldn't have kept him fed any other way, Surgeon Trink had done his best in an emergency.

The surgeon was willing to accept blame for having introduced Savold so bluntly to his family, but the board absolved him—none of them had had any experience in dealing with an Earth mentality. A Dorfellow would have accepted the fact, as others with amnesia caused by accidents had done. Surgeon Trink had had no reason to think Savold would not have done the same. Savold cleared the surgeon entirely by admitting that the memory was there, but, like all the other memories of Gam Nex Biad's, had been activated only when the situation came up. The board had no trouble getting Savold to agree that the memory would have returned sooner or later, no matter how Surgeon Trink handled the introduction, and that the reaction would have been just as violent.

"And now," gleamed the oldest surgeon on the board, "the problem is how to help our new—and restored—brother adjust to life on this world."

"That isn't the problem at all!" Savold flared savagely. "I have to get back to Earth and tell them I dropped the bomb and they can land safely. And there's the girl I mentioned. I want to marry her—become her mate, I mean."

"You want to become her mate?" the oldest surgeon blinked in bewilderment. "It is your decision?"

"Well, hers, too."

"You mean you did the selecting yourselves? Nobody chose for you?" Savold attempted to explain, but puzzled glimmers and Gam Nex Biad's confusion made him state resignedly, "Our customs are different. We choose our own mates." He thought of adding that marriages were arranged in some parts of the world, but that would only have increased their baffled lack of understanding.

"And how many mates can an individual have?" asked a surgeon.

"Where I come from, one."

"The individual's responsibility, then, is to the family he has. Correct?"

"Of course."

"Well," said the oldest surgeon, "the situation is perfectly clear. You have a family—Prad Fim Biad and the children."

"They're not my family," Savold objected. "They're Gam Nex Biad's and he's dead."

"We respect your customs. It is only fair that you respect ours. If you had had a family where you come from, there would have been a question of legality, in view of the fact that you could not care for them simultaneously. But you have none and there is no such question."

"Customs? Legality?" asked Savold, feeling as lost as they had in trying to comprehend an alien society.

"A rebuilt Dorfellow," the oldest surgeon said, "is required to assume the obligations of whatever major parts went into his reconstruction. You are almost entirely made up of the remains of Gam Nex Biad, so it is only right that his mate and children should be yours."

"I won't do it!" Savold protested. "I demand the right to appeal!"

"On what grounds?" asked another surgeon politely.

"That I'm not a Dorfellow!"

"Ninety-four point seven per cent of you is, according to Surgeon Trink's requisition of limbs and organs. How much more of a citizen can any individual be?"

Gam Nex Biad confirmed the ruling and Savold subsided. While the board of surgeons discussed the point it had begun with—how to adapt Savold to life on Dorfel—he thought the situation through. He had no legal or moral recourse. If he was to get out of his predicament, it would have to be through shrewd resourcefulness and he would never have become a major in the space fleet if he hadn't had plenty of that.

Yeah, shrewd resourcefulness, thought Savold bitterly, jouncing unsteadily on his single bedspring leg on a patch of unappealing topsoil a little distance from the settlement. He had counted on something that didn't exist here—the kind of complex approach that Earth doctors and authorities would have used on his sort of problem, from the mitigation of laws to psychological conditioning, all of it complicated and every stage allowing a chance to work his way free.

But the board of surgeons had agreed on a disastrously simple course of treatment for him. He was not to be fed by anybody and he could not sleep in any of the underground rock apartments, including the dormitory for unmated males.

"When he's hungry enough, he'll go back to mining," the oldest surgeon had told the equivalent of a judge, a local teacher who did part-time work passing on legal questions that did not have to be ruled on by the higher courts. "And if he has no place to stay except with Gam Nex Biad's family, which is his own, naturally, he'll go there when he's tired of living out in the open all by himself." The judge thought highly of the decision and gave it official approval. Savold did not mind being out in the open, but he was far from being all by himself. Gam Nex Biad was a constant nuisance, nagging at him to get in a good day's drilling and then go home to the wife, kiddies, and their cozy, hollowed-out quarters, with company over to celebrate his return with a lavish supply of capsuled lubricating oil. Savold obstinately re fused, though he found himself salivating or something very much like it.

The devil of the situation was that he was hungry and there was not a single bit of rock around to munch on. That was the purpose of this fenced-in plot of ground—it was like hard labor in the prisons back on Earth, where the inmates ate only if they broke their quota of rock, except that here the inmates would eat the rock they broke. The only way Savold could get out of the enclosure was by drilling under the high fence. He had already tried to bounce over it and discovered he couldn't.

"Come on," Gam Nex Biad argued in his mind. "Why fight it? We're a miner and there's no life like the life of a miner. The excitement of boring your way through a lode, making a meal out of the rich ore!

Miners get the choicest tidbits, you know—that's our compensation for working so hard and taking risks."

"Some compensation," sneered Savold, looking wistfully up at the stars and enviously wishing he were streaking between them in his scout.

"A meal of iron ore would go pretty well right now, wouldn't it?" Gam Nex Biad tempted. "And I know where there are some veins of tin and sulphur. You don't find them lying around on the surface, eh? Non-miners get just traces of the rare metals to keep them healthy, but we can stuff ourself all we want . . ."

"Shut up!"

"And some pools of mercury. Not big ones, I admit, but all we'd want is a refreshing gulp to wash down those ores I was telling you about."

Resisting the thought of the ores was hard enough, for Savold was rattlingly empty, but the temptation of the smooth, cool mercury would have roused the glutton in anyone.

"All right," he growled, "but get this straight—we're not going back to your family. They're your problem, not mine."

"But how could I go back to them if you won't go?"

"That's right. I'm glad you see it my way. Now where are those ores and the pools of mercury?"

"Dive," said Gam Nex Biad. "I'll give you the directions." Savold took a few bounces to work up speed and spin, then shot into the air and came down on the point of his awl-shaped head, which bit through the soft topsoil as if through—he shuddered—so much water. As a Dorfellow, he had to avoid water; it eroded and corroded and caused deposits of rust in the digestive and circulatory systems. There was a warmth that was wonderfully soothing and he was drilling into rock. He ate some to get his strength back, but left room for the main meal and the dessert.

"Pretty nice, isn't it?" asked Gam Nex Biad as they gouged a comfortable tunnel back toward the settlement. "Non-miners don't know what they're missing."

"Quiet," Savold ordered surlily, but he had to confess to himself that it was pleasant. His three knee-action arms rotated him at a comfortable speed, the horn spades pushing back the loose rock; and he realized why Gam Nex Biad had been upset when Surgeon Trink left Savold's human arms attached. They were in the way and they kept getting scratched. The row of socketed bulbs gave him all the light he needed. That, he decided, had been their original purpose. Using them to communicate with must have been one of the first steps toward civilization.

Savold had been repressing thoughts ever since the meeting of the board of surgeons. Experimentally, he called his inner partner.

"Um?" asked Gam Nex Biad absently.

"Something I wanted to discuss with you," Savold said. "Later. I sense the feldspar coming up. We head north there."

Savold turned the drilling over to him, then allowed the buried thoughts to emerge. They were thoughts of escape and he had kept them hidden because he was positive that Gam Nex Biad would have betrayed them. He had been trying incessantly, wheedlingly, to sell Savold on mining and returning to the family.

The hell with that, Savold thought grimly now. He was getting back to Earth somehow—Earth Command first, Marge second. No, surgery second, Marge third, he corrected. She wouldn't want him this way . . .

"Manganese," said Gam Nex Biad abruptly, and Savold shut off his thinking. "I always did like a few mouthfuls as an appetizer."

The rock had a pleasantly spicy taste, much like a cocktail before dinner. Then they went on, with the Dorfellow giving full concentration to finding his way from deposit to deposit. The thing to do, Savold reasoned, was to learn where the scout ship was being kept. He had tried to sound out Gam Nex Biad subtly, but it must have been too subtle—the Dorfellow had guessed uninterestedly that the ship would be at one of the metal fabricating centers, and Savold had not dared ask which one. Gam Nex Biad couldn't induce him to become a miner and Dorfellow family man, but that didn't mean he could escape over Gam Nex Biad's opposition.

Savold did not intend to find out. Shrewd resourcefulness, that was the answer. It hadn't done him much good yet, but the day he could not outfox these rock-eaters, he'd turn in his commission. All he had to do was find the ship . . .

Bloated and tired, Savold found himself in a main tunnel thoroughfare back to the settlement. The various ores, he disgustedly confessed to himself, were as delicious as the best human foods and there was nothing at all like the flavor and texture of pure liquid mercury. He discovered some in his cupped cilia hands.

"To keep around for a snack?" he asked Gam Nex Biad.

"I thought you wouldn't mind letting Prad Fim and the children have some," the Dorfellow said hopefully. "You ought to see them light up whenever I bring it home!"

"Not a chance! We're not going there, so I might as well drop it." Savold tried to open his cilia hands. They stayed cupped. That was when he realized that he had supposed correctly. Gam Nex Biad could prevent him from escaping. Savold had to get some sleep. He was ready to topple with exhaustion. But the tunnels were unsafe—a Dorfellow traveling through one on an emergency night errand would crash into him hard enough to leave nothing but flinty splinters. And the night air felt chill and hostile, so it was impossible to sleep above ground.

"Please make up your mind," Gam Nex Biad begged. "I can't stay awake much longer and you'll just go blundering around and get into trouble."

"But they've got to put us up somewhere," argued Savold. "How about the hospital? We're still a patient, aren't we?"

"We were discharged as cured. And nobody else is allowed to let us stay in any apartment . . . except one."

"I know, I know," Savold replied with weary impatience. "Forget it. We're not going there."

"But it's so comfortable there . . ."

"Forget it, I told you!"

"Oh, all right," Gam Nex Biad said resignedly. "But we're not going to find anything as pleasant and restful as my old sleeping boulder. It's soft limestone, you know, and grooved to fit our body. I'd like to see anybody not fall asleep instantly on that good old flat boulder . . ." Savold tried to resist, but he was worn out from the operation, hunger, digging, and the search for a place to spend the night.

"Just take a look at it, that's all," Gam Nex Biad coaxed. "If you don't like it, we'll sleep anywhere you say. Fair enough?" "I suppose so," admitted Savold.

The hewn-rock apartment was quiet, at least; everybody was asleep. He'd lie down for a while, just long enough to get some rest, and clear out before the household awoke . . . But Prad Fim and the children were clustered around the boulder when he opened his eyes. Each of them had five arms to fight off. And there were Surgeon Trink, the elder of the board of surgeons, and the local teacher-judge all waiting to talk to him when the homecoming was over with.

"The treatment worked!" cried the judge. "He came back!" "I never doubted it," the elder said complacently.

"You know what this means?" Surgeon Trink eagerly asked Savold.

"No, what?" Savold inquired warily, afraid of the answer.

"You can show us how to operate your machine," declared the judge. "It isn't that we lack engineering ability, you understand. We simply never had a machine as large and complex before. We could have, of course—I'm sure you are aware of that—but the matter just didn't come up. We could work it out by ourselves, but it would be much easier to have you explain it."

"By returning, you've shown that you have regained some degree of stability," added the elder. "We couldn't trust you with the machine while you were so disturbed."

"Did you know this?" Savold silently challenged Gam Nex Biad.

"Well, certainly," came the voiceless answer.

"Then why didn't you tell me? Why did you let me go floundering around instead?"

"Because you bewilder me. This loathing for our body, which I'd always been told was quite attractive, and dislike of mining and living with our own family—wanting to reach this thing you call Earth Command and the creature with the strange name. Marge, isn't it? I could never guess how you would react to anything. It's not easy living with an alien mentality."

"You don't have to explain. I've got the same problem, remember."

"That's true," Gam Nex Biad silently agreed. "But I'm afraid you'll have to take it from here. All I know is mining, not machines or metal fabricating centers."

Savold repressed his elation. The less Gam Nex Biad knew from this point on, the less he could guess—and the smaller chance there was that he could betray Savold.

"We can leave right now," the judge was saying. "The family can follow as soon as you've built a home for them."

"Why should they follow?" Savold demanded. "I thought you said I was going to be allowed to operate the ship."

"Demonstrate and explain it, really," the judge amended. "We're not absolutely certain that you are stable, you see. As for the family, you're bound to get lonesome . . ." Savold stared at Prad Fim and the children. Gam Nex Biad was brimming with affection for them, but Savold saw them only as hideous, ore-crushing monsters. He tried to keep them from saying good-by with embraces, but they came at him with such violent leaps that they chipped bits out of his body with their grotesque pointed awl heads. He was glad to get away, especially with Gam Nex Biad making such a damned slobbering nuisance of himself.

"Let's go!" he blinked frantically at the judge, and dived after him into an express tunnel. While Gam Nex Biad was busily grieving, Savold stealthily worked out his plans. He would glance casually at the ship, glow some mild compliment at the repair job, make a pretense at explaining how the controls worked—and blast off into space at the first opportunity, even if he had to wait for days. He knew he would never get another chance; they'd keep him away from the ship if that attempt failed. And Gam Nex Biad was a factor, too. Savold had to hit the take-off button before his partner suspected or their body would be paralyzed in the conflict between them.

It was a very careful plan and it called for iron discipline, but that was conditioned into every scout pilot. All Savold had to do was maintain his rigid self-control.

He did—until he saw the ship on the hole-pocked plain. Then his control broke and he bounced with enormous, frantic leaps into the airlock and through the corridors to the pilot room.

"Wait! Wait!" glared the judge, and others from the fabricating center sprang toward the ship. Savold managed to slam the airlock before Gam Nex Biad began to fight him, asking in frightened confusion, "What are you doing?" and locking their muscles so that Savold was unable to move.

"What am I doing?" glinted Savold venomously. "Getting off your lousy planet and back to a world where people live like people instead of like worms and moles!"

"I don't know what you mean," said the Dorfellow anxiously, "but I can't let you do anything until the authorities say it's all right."

"You can't stop me!" Savold exulted. "You can paralyze everything except my own arms!" And that, of course, was the ultimate secret he had been hiding from Gam Nex Biad. Savold slammed the take-off button. The power plant roared and the ship lifted swiftly toward the sky.

It began to spin.

Then it flipped over and headed with suicidal velocity toward the ground.

"They did something wrong to the ship!" cried Savold.

"Wrong?" Gam Nex Biad repeated vacantly. "It seems to be working fine."

"But it's supposed to be heading up!"

"Oh, no," said Gam Nex Biad. "Our machines never go that way. There's no rock up there." JOURNAL NOTES: Man of Parts

THEME: Herbivores live on vegetation and carnivores live on herbivores, so all Earth life is based on plants. Why not eliminate the middlemen, so to speak, and have an extraterrestrial race that lives directly on the metals and minerals of a planet's crust?

POSSIBILITIES: Tell from viewpoint of a member of the race? Too alien; the reader can't identify strongly. Viewpoint of human visitors to the planet? Too detached; should experience life there, but contrasting human and alien psychology and society subjectively. Only answer is combining the two in one person, the protagonist—bone and organ bank used to save life of man hurt in crash landing on the planet.

DEVELOPMENT: Using bank to put human and alien identities in one body solves two problems—sharp narrative hook because protagonist has two recollections of who he is (or was) and how he got injured; also eliminates need to learn alien language. But he should be alone to emphasize his reactions. No point killing everybody in a ship except one guy; gory and needless, also too contrived. One-man scout mission, his craft crippled, emergency landing, bang. He's badly damaged, but even better reason for reconstructing him from alien accident victim —he can't survive unless he can get his nourishment same way they do. Give him urgent ties to Earth, such as important assignment in interstellar war and a girl back home. But give his alien body-partner equally vital obligations, such as job he's conditioned to and a family. Then let the two battle. Show what it's like to live on rock and minerals, whole society as seen by human and interpreted by alien. Good twists possible at end—being spared flesh arms is a nuisance when digging, but can be used to break alarmed control of body by alien when ship (repaired now) is reached; ship converted for digging—why would rock-eaters want to go into space? No rock there.

EDITORIAL COMMENT: A story that can make real an entire alien society, while getting the reader to identify with the protagonist—and all in only 5,000 words—is something to be proud of. Not too many years ago, I'd have needed two or three times this length to get the same data and effects across, which naturally would have diffused the impact. Critic Damon Knight thought I was kicking up literary divots just for the hell of it and Editor Raymond J. Healy considered it the final crushing word on multiple-personality stories. Well, maybe; it's always good to learn afterward what one had in mind, but I was exploring a theme I hadn't encountered elsewhere and trying to get maximum results with minimum wordage. It demanded careful working out and three drafts before it could be achieved. When Michelangelo said,

"Only work can eliminate the traces of work," he wasn't kidding.
