"BUT WHY YOU?" she asked.

"Because it happens to be my job." He clicked the last belt loop into place on his pack and shifted its weight comfortably on his shoulders.

"I don't understand why those men, the ones flying the delivery ship, why they couldn't have looked around first. To help you out a little bit, perhaps let you know what you were getting into. I don't think it's fair."

"It's very fair," he told her, tightening up one notch on the left shoulder strap and trying to keep his temper. He did not like her to come here when he was leaving, but there was no easy way to stop her.

Once again he explained.

"The men who fly the contact ships have a difficult time of it just staying alive and sane, trapped in their ships while they go out to the stars. Theirs is a specialized job; only certain men with particular dispositions can survive the long flight. These same characteristics are outstandingly unsuited to planetary contact and exploration. It is work enough for them to do a high-level instrument and photographic sweep, and then to drop a transmatter screen on retrojets at a suitable spot. By the time the transmatter touches down and sends back their report they are well on their way to the next system. They've done their job. Now I'll do mine."

"Ready for me yet, Specialist Langli?" a man asked, looking in through the ready-room door.

"Just about," Langli said, disliking himself for the relief he felt at the other's intrusion. "Artificer Meer, this is my wife, Keriza."

"A great honor, Wife Keriza. You must be proud of your husband."

Meer was young and smiled when he talked, so it could be assumed that he was sincere about what he said. He wore a throat mike and earphones and was in constant contact with the computer.

"It is an honor," Keriza said, but could not prevent herself from adding, "but not an eternal one. This is a first betrothal and it expires in a few days, while my husband is away."

"Fine," Artificer Meer said, not hearing the bitterness behind her words. "You can look forward to a second or final when he returns. A good excuse for a celebration. Shall I begin, Specialist?"

"Please do," Langli said, lifting his canteen with his fingertips to see if it was full.

Keriza retreated against the wall of the drab room while the checklist began; she was already left out.

The computer murmured its questions into the artificer's ear and he spoke them aloud in the same machine made tones. Both men attended to the computer, not to her, alike in their dark green uniforms, almost the same color as the green painted walls. The orange and silver of her costume was out of place here and she unconsciously stepped backward toward the entrance.

The checklist was run through quickly & met the computer's approval. Far more time was then taken up making the needed adjustments on Langli's manpower gear. This was a powered metal harness that supported his body, conforming to it like a flexible exoskeleton. It was jointed at his joints and could swivel and turn to follow any motion.

Since the supporting pads were an integral part of his uniform, and the rods were thin and colored to match the cloth, it was not too obvious. An atomic energy supply in his pack would furnish power for at least a year.

"Why are you wearing that metal cage?" Keriza asked. "You have never done that before." She had to repeat her question, louder, before either man noticed her.

"It's for the gravity," her husband finally told her. "There's a two point one five three plus G on this planet. The manpower can't cancel that, but it can support me and keep me from tiring too quickly."

"You didn't tell me that about this planet. In fact you have told me nothing."

"There's little enough. High gravity, cold and windy where I'm going. The air is good; it's been tested, but oxygen is a little high. I can use it."

"But animals, wild animals, are there any of them? Can it be dangerous?"

"We don't know yet, but it appears peaceable enough. Don't worry about it." This was a lie, but one officially forced upon him. There were human settlers on this new planet, and this was classified information. A public announcement would be made only after official appraisal of his report.

"Ready," Langli said, pulling on his gloves. "I want to go before I start sweating inside this suit."

"Suit temperature is thermostatically controlled, Specialist Langli. You should not be uncomfortable."

He knew that: he just wanted to leave. Keriza should not have come here.

"Restricted country from here in," he told her, taking her arms and kissing her quickly. "I'll send you a letter as soon as I have time."

He loved her well enough, but not here, not when he was going on a mission. The heavy door closed behind them, shutting her out, and he felt relieved at once. Now he could concentrate on the job.

"Message from control," the artificer said when they entered the armored transmatter room through the thick triple doors. "They want some more vegetation and soil samples. Life forms and water, though these last can wait."

"Will comply," Langli said, and the artificer passed on the answer through his microphone.

"They wish you quick success, Specialist," the artificer said in his neutral voice, then, more warmly, "I do, too. It is a privilege to have assisted you." He covered the microphone with his hand. "I'm studying, a specialist course, and I've read your reports. I think that you c I mean what you have donec." His words died and his face reddened. This was a breach of rules and he could be disciplined.

"I know what you mean, Artificer Meer, and I wish you all the best of luck." Langli extended his hand and, after a moment's reluctance, the other man took it. Though he would not admit it aloud, Langli was warmed by this irregular action. The coldness of the transmatter chamber, with its gun snouts and television cameras, had always depressed him. Not that he wanted bands or flags when he left, but a touch of human contact made up for a lot.

"Goodbye, then," he said, and turned and activated the switch on the preset transmatter control. The wire lattice of the screen vanished and was replaced by the watery blankness of the operating Bhattacharya field. Without hesitating Langli stepped into it.

An unseen force seized him, dragging him forward, hurling him face first to the ground. He threw his arms out to break his fall and the safety rods on his wrists shot out ahead of his hands, telescoping slowly to soften the shock of impact; if they had not he would surely have broken both his wrists.

Even with this aid the breath was knocked from him by the impact of the manpower pads. He gasped for air, resting on all fours. His mouth burned with the coldness of it and his eyes watered. The uniform warmed as the icy atmosphere hit the thermocouples. He looked up.

A man was watching him. A broad, solidly built man with an immense flowing black beard. He was dressed in red-marked leather and furs and carried a short stabbing spear no longer than his forearm. It was not until he moved that Langli realized he was standing up not sitting down. He was so squat and wide that he appeared to be truncated.

First things came first: control had to have its samples. He kept a wary eye on the bearded man as he slipped a sample container from the dispenser on the side of his pack and put it flat on the ground. The ground was hard but ridged like dried mud, so he broke off a chunk and dropped it into the middle of the red plastic disc. Ten seconds later, as the chemicals in the disc reacted with the air, the disc curled up on the edges and wrapped the soil in a tight embrace.

The other man shifted his spear from hand to hand and watched this process with widening eyes. Langli filled two more containers with soil, then three others with grass and leafy twigs from a bush a few feet away. This was enough. Then he backed slowly around the scarred bulk of the retrorockets until he stood next to the transmatter screen.

It was operating but unfocused: anything entering it now would be broken down into Y-radiation and simply sprayed out into Bhattacharya space. Only when he pressed his hand to the plate on the frame would it be keyed to the receiver; it would operate for no one else. He touched the plate and threw the samples through. Now he could turn to the more important business.

"Peace," he said, facing the other man with his hands open and extended at his sides. "Peace."

The man did nothing in response, though he raised the spear when Langli took a step toward him. When Langli returned to his original position he dropped the spear again. Langli stood still and smiled.

"It's a waiting game, is it? You want to talk while we're waiting?" There was no answer, nor did he really expect one. "Right then, what is it we're waiting for? Your friends, I imagine. All of this shows organization, which is very hopeful. Your people have a settlement nearby, that's why the transmatter was dropped here. You investigated it, found no answers, then put a guard on it. You must have signaled them when I arrived, though I was flat on my face and didn't see it."

There was a shrill squealing behind a nearby slope that slowly grew louder. Langli looked on with interest as a knot of bearded men, at this distance looking identical with his guard, struggled into sight They were all pulling a strange conveyance which had three pasts of wooden wheels: the apparently unoiled axles were making the squealing. It was no more than a padded platform on which rested a man dressed in bright-red leather.

The upper part of his face was hidden by a metal casque pierced with eyeslits, but from below the rim a great white beard flowed across his chest. In his right hand the man held a long, thin-bladed carving knife which he pointed at Langli as he slowly stepped down from the conveyance. He said something incomprehensible in a sharp hoarse voice at the same time.

"I'm sorry, but I cannot understand you," Langli said.

At the sound of his words the old man started back and nearly dropped the weapon. At this sudden action the other men crouched and raised their spears toward Langli. The leader disapproved of this and shouted what could only have been commands. The spears were lowered at once. When he was satisfied with the reaction the man turned back to Langli and spoke slowly, choosing his words with care.

"I did not know c think c I would these words hear spoken by another. I know it only to read." The accent was strange but the meaning was perfectly clear.

"Wonderful. I will learn your language, but for now we can speak minec"

"Who are you? What is it c the thing there, it fell at night with a loud noise. How come you here?"

Langli spoke slowly and clearly, what was obviously a prepared speech.

"I come with greetings from my people. We travel great distances with this machine you see before you. We are not from this world. We will help you in many ways which I will tell you. We can help the sick and make them well. We can bring food if you are hungry. I am here alone and no more of us will come unless you permit it. In return for these things we ask only that you answer my questions. When the questions are answered we will answer any questions that you may have."

The old man stood with his legs widespread and braced, unconsciously whetting the blade on his leg.

"What do you want here? What are your real needs c desires?"

"I have medicine and can help the sick. I can get food. I ask only that you answer my questions, nothing more.

Under the flowing moustache the old man's lips lifted in a cold grin. "I understand. Do as you say, or do nothing. Come with me then." He stepped backward and settled slowly onto the cart which creaked with his weight. "I am Bekrnatus. You have a name?"

"Langli. I will be happy to accompany you."

They went in a slow procession over the crest of the rise and down into the shallow valley beyond.

Langli was already tired, his heart and lungs working doubly hard to combat the increased gravity, and was exhausted before they had gone a quarter of a mile.

"Just a moment," he said. "Can we stop for a short while?"

Bekrnatus raised his hand and spoke a quick command. The procession stopped and the men immediately sat, most of them sprawling out horizontally in the heavy grass. Langli unclipped his canteen and drank deeply. Bekrnatus watched every move closely.

"Would you like some water?" Langli asked, extending the canteen.

"Very much," the old man said, taking the canteen and examining it closely before drinking from it. "The water has a taste of very difference. Of what metal is this c container made?"

"Aluminum I imagine, or one of its alloys."

Should he have answered that question? It certainly seemed harmless enough. But you never could tell.

Probably he shouldn't have, but he was too tired to really care. The bearded men were watching intently and the nearest one stood up, staring at the canteen.

"Sorry," Langli said, blinking a redness of fatigue from his eyes and extending the canteen to the man.

"Would you like a drink as well?"

Bekrnatus screamed something hoarsely as the man hesitated a moment then reached out and clutched the canteen. Instead of drinking from it he turned and started to run away. He was not fast enough. Langli looked on, befuddled, as the old man rushed by him and buried his long knife to the hilt in the fleeing man's back.

None of the others moved as the man swayed, then dropped swiftly and heavily to the ground. He lay on his side, eyes open and blood gushing from his mouth, the canteen loose in his fingers. Bekrnatus kneeled and took away the canteen, then jerked the knife out with a single powerful motion. The staring dead eyes were still.

"Take this water thing and do not come c go near other people or give them anythings."

"It was just water."

"It was not the water. You killed this man."

Langli, befuddled, started to tell him that it was perfectly clear who had killed him, then wisely decided to keep his mouth shut. He knew nothing about this society and had made a mistake. That was obvious.

In a sense the old man was right and he had killed the man. He fumbled out a stimulant tablet and washed it down with water from the offending canteen. The march resumed.

The settlement was in the valley, huddled against the base of a limestone cliff, and Langli was exhausted when they reached it. Without the manpower he could not have gone a quarter of this distance. He was in among the houses before he realized they were there, so well did they blend into the landscape. They were dugouts, nine-tenths below the ground, covered with flat sod roofs; thin spirals of smoke came from chimney openings in most of them. The procession did not stop, but threaded its way through the dug-in houses and approached the cliff.

This had a number of ground-level openings cut into it, the larger ones sealed with log doors. When they were closer Langli saw that two window-like openings were covered with glass or some other transparent substance. He wanted to investigate this but it would have to wait. Everything would have to wait until he regained a measure of strength.

He stood, swaying, while Bekrnatus climbed slowly down from the wheeled litter and approached a log door which opened as he came near. Langli started after him then found himself falling, unable to stand. He had a brief moment of surprise, before the ground came up and hit him, when he realized that for the first time in his life he was fainting.

The air was warm on his face and he was lying down. It took him some moments, even after he had opened his eyes, to realize where he was. An immense fatigue gripped him and every movement was an effort; even his thoughts felt drugged. He looked about the darkened room several times before the details made any meaning. A window that was set deep into the stone wall. The dim bulk of furniture and unknown objects. A weaker, yellow light from the fire on the grate. A stone fireplace and stone walls.

Memory returned and he realized that he must be in one of the rooms he had noticed, hollowed out of the face of the cliff. The fire crackled; there was the not-unpleasant odor of pungent smoke in the air; soft, slapping footsteps came up behind him. He felt too tired to turn his head, but he banished this unworkmanlike thought and turned in that direction.

A girl's face, long blond hair, deep blue eyes.

"Hello. I don't believe we have met," he said.

The eyes widened, shocked, and the face vanished. Langli sighed wearily and closed his own eyes. This was a very trying mission. Perhaps he should take a stimulant. In his pack.

His pack! He was wide awake at the thought, struggling to sit up. They had taken his pack from him? At the same instant of fear he saw it lying next to the cot where it had been dropped. And the girl returned, pressing him back to a lying position. She was very strong.

"I'm Langli. What's your name?"

She was attractive enough, if you liked your girls squarefaced. Good bust, filled the soft leather dress nicely. But that was about all. Too broad-shouldered, too hippy, too much muscle. Very little different really from the other natives of this heavy planet. He realized that her eyes had never left his while he had been looking her up and down. He smiled.

"Langli is my name, but I suppose I shall never learn yours. The leader what did he call himself Bekrnatus, seems to be the only one who speaks a civilized tongue. I suppose I shall have to learn the local grunts and gurgles before I will be able to talk to you?"

"Not necessarily," she said, and burst out laughing at the surprised look on his face. Her teeth were even, white, and strong. "My name is Patna. Bekrnatus is my father."

"Well, that's nice." He still felt dazed. "Sorry if I sounded rude. The gravity is a little strong for me."

"What is gravity?"

"I'll tell you later, but I must talk to your father first. Is he here?"

"No. But he will be soon back. Today he killed a man. He must now the man's wife and family look after. They will go to another. Can I not answer your questions?"

"Perhaps." He touched the button on his waist that switched on the recorder. "How many of your people speak my language?"

"Just me. And Father, of course. Because we are The Family and the others are The People." She stood very straight when she said it.

"How many are there, of The People I mean?"

"Almost six hundred. It was a better winter than most. The air was warmer than in other years. Of course there was more; what is the word? more rot in the stored food. But people lived."

"Is winter over yet?"

She laughed. "Of course. It is almost the warmest time now."

And they believe that this is warm, he thought. What can the winters be possibly like? He shivered at the thought.

"Please tell me more about The Family and The People. How are they different?"

"They just are, that is all," she said and stopped, as though she had never considered the question before. "We live here and they live there. They work and they do what we tell them to do. We have the metal and the fire and the books. That is how we talk your language, because we read what is written in the books."

"Could I see the books?"

"No!" She was shocked at the thought. "Only The Family can see them."

"Well-wouldn't you say that I qualify as a member of The Family? I can read, I carry many things made of metal." At that moment he realized what the trouble had been with his canteen. It was made of metal, for some reason taboo among most of these people. "And I can make fire." He took out his lighter and thumbed it so that a jet of flame licked out.

Patna looked at this, wide-eyed. "Our fires are harder to make. But, still, I am not sure. Father will know if you should look at the books." She saw his expression and groped around for some compromise. "But there is one book, a little book, that Father lets me have for my own. It is not an important book, though."

"Any book is important. May I see it?"

She rose hesitantly and went to the rear of the room, to a log door let into the stone, and tugged at the thick bars. When it was open she groped into the darkness of another room, a deeper cavern cut into the soft stone of the cliff. She returned quickly and resealed the door.

"Here," she said, holding it out to him, "you may read my book."

Langli struggled to a sitting position & took it from her. It was crudely bound in leather, the original cover must have worn out countless years earlier and it crackled when he opened it. The pages were yellowed, frayed, & loose from the backbone. He poked through them, squinting at the archaic typeface in the dim light from the window, then turned back to the title page.

"Selected Poems," he read aloud. "Published at, I've never heard of the place, in c this is more importantc 785 p.v. I think I've heard of that calendar, just a moment."

He put the book down carefully and bent to his pack, almost losing his balance as the more than doubled gravity pulled at him. His exoskeleton hummed and gave him support. The handbook was right on top and he flipped through it.

"Yes, here it is. Only went to 913 in their reckoning. Now to convert to Galactic Standardc." He did some silent figuring and put the handbook away, taking up the other book again. "Do you like poetry?" he asked.

"More than anything. Though I only have these. There are no other poems in the books. Though of course there are some othersc"

She lowered her eyes and, after a moment's thought, Langli realized why.

"These others, you wrote them yourself, didn't you? You must tell me one sometime"

There was a sudden rattling at the bolts that sealed the front door and Patna tore the book from his hands and ran with it to the dark end of the room.

Bekrnatus pushed open the door and came in wearily. "Close it," he ordered as he threw aside his helmet and dropped into a padded lounge, half bed, half chair. Patna moved quickly to do his bidding.

"I am tired, Langli," he said, "and I must sleep. So tell me what you are doing here, what this all means."

"Of course. But a question or two first. There are things I must know. What do your people do here, other than sleep and eat and gather food?"

"The question makes no sense."

"I mean anything. Do they mine and smelt metal? Do they carve, make things from clay, paint pictures, wear jewelry "

"Enough. I understand your meaning. I have read of these things, seen pictures of them. Very nice. In answer to your question, we do nothing. I could never understand how these things were done and perhaps you will tell me when it suits you to answer questions rather than ask them. We live, that is hard enough. When we have planted our food and picked our food we are through. This is a hard world and the act of living takes all of our time."

He barked a harsh command in the local language, and his daughter shuffled to the fireplace. She returned with a crude clay bowl which she handed to him. He raised it to his lips and drank deeply, making smacking noises with his lips.

"Would you care for some?" he asked. "It is a drink we make; I do not know if there is a word for it in the book language. Our women chew roots and spit them into a bowl."

"No, none thank you." Langli fought to keep his voice even, to control his disgust. "Just one last question. What do you know of your people coming to this world? You do know that you came here?"

"Yes, that I know, though little more. The story is told, though nothing is written, that we came from another world to this world, from the sky, though how it was done I know not. But it was done, for the books are not of this world and they have pictures of scenes not of this world. And there is the metal, and the windows. Yes, we came here."

"Have others come? Like myself. Are there records?"

"None! That would have been written. Now you tell me, stranger from the metal box. What do you do here?"

Langli lay down, carefully, before he spoke. He saw that Patna was sitting as well. The gravity must be fought, constantly, unceasingly.

"First you must understand that I came from inside the metal box, then again I didn't. At night you see the stars and they are suns like the one that shines here, yet very distant. They have worlds near them, like this world here. Do you know what I am talking about?"

"Of course. I am not of The People. I have read of astronomy in the books."

"Good. Then you should know that the metal box contains a transmatter which you must think of as a kind of door. One door that is at the same time two doors. I stepped through a door on my planet, very far away, and stepped out of your door here. All in an eye-blink of time. Do you understand?"

"Perhaps." Bekrnatus dabbed at his lips with the back of his hand. "Can you return the same way? Step into the box and come out on a planet, up there in the sky."

"Yes, I can do that."

"Is that how we came to this world?"

"No. You came by a ship of space, a large metal box built to move between the stars, in the years before the transmatter could be used at stellar distances. I know this because your window there is the window from a spacer, and I imagine your metal was salvaged from the ship as well. And I also know how long you have been here, since there was a date in the front of that poetry book your daughter showed me."

Patna gasped, a sharp intake of air, and Bekrnatus pulled himself to a sitting position. The clay bowl fell, unheeded, and shattered on the floor.

"You showed him a book," Bekrnatus hissed, and struggled to his feet.

"No, wait!" Langli said, realizing he had precipitated another crisis through ignorance. Would the man try to kill his daughter? He tore at his pack. "It was my fault, I asked for the book. But I have many books; here I'll show you. I'll give you some books. This c and this."

Bekrnatus did not heed the words, if he even heard them, but he stopped as the books were pushed before him. He reached for them hesitantly.

"Books," he said, dazedly. "Books, new books, books I have never seen before. It is beyond wonder."

He clutched the books to his chest and half fell back into his chair. A good investment, Langli thought.

Never was a first reader and a basic dictionary more highly prized.

"You can have all the books you want now. You can discover your history, all of it. I can tell you that your people have been here, roughly, about three thousand years. Your coming here may have been an accident; two things lead me to believe that. This is a very grim world with little to offer. I can't picture it being selected for colonization. Then there is the complete break with technology and culture. You have a few books, they could have been salvaged.

And metal, perhaps from the wreck of the ship. That you have survived is little short of miraculous. You have this social or class distinction that has also passed down. Your ancestors were perhaps scientists, ship's officers, something that set them apart from ordinary men. And you have kept the distinction."

"I am tired," Bekrnatus said, turning the books over and over in his hands, "and there are many new things to think about all at once. We will talk tomorrow."

He dropped back, eyes closed, books still in his grasp. Langli was ready to sleep himself, exhausted by the efforts he had forced himself to. The light seemed to be fading; he wondered how long the local day was, and did not really care. He took an eight-hour sleeping pill from his medical kit and washed it down with water from his canteen. A night's sleep would make things look a good deal different.

During the night he was aware of someone moving about, going to the fire. At one time he thought he felt the soft touch of hair across his face and lips upon his forehead. But he could not be sure and thought it was probably a dream.

It was bright morning when he awoke, with the sun striking directly through the window, the shaft of light adding unexpected color to the gray stone of the back wall. Bekrnatus' couch was empty and Patna was working at the fireplace, humming quietly to herself. When he shifted position his bed squeaked and she turned to look at him.

"You are awake. I hope that you slept well. My father has gone out with the ax so wood can be chopped."

"You mean that he chops the wood?" Langli yawned, his head still thick with sleep.

"No, never. But the ax head is metal so he carries it and must be there when it is used. Your morning food is ready." She ladled one of the clay bowls full of gruel and brought it to him. He smiled and shook his head no.

"Thank you, that is very hospitable. But I cannot eat any of your food until laboratory analysis has been made"

"You think I am trying to poison you?"

"Not at all. But you must realize that major metabolic changes take place in human beings cut off from the main stream. There may be chemicals in the soil here, in the plants, that you can ingest but that would be sure death for me. It smells wonderful, but it could hurt me. You wouldn't want that to happen?"

"No! Of course not." She almost hurled the bowl from her. "What will you eat?"

"I have my own food here, see."

He opened his pack and took out a mealcel, pulling the tab so the heating began. He was hungry, be realized, hungrier than he had ever felt before, and began spooning down the concentrate before the heat cycle was finished. His body needed nourishment, fighting constantly against the drag of gravity.

"Do you know what this is?" Patna asked, and he looked up to see her holding a brownish, ragged-edged fragment of some kind.

"No, I don't. It looks like wood or bark."

"It is the inner bark of a tree, we use it to write on, but that is not what I meant. I meant there is something on it. That is what I meantc.

Even in the dim light Langli could realize that she was blushing. Poor girl, a literate among savages, trapped on this dismal and isolated world.

"I might guess," he said carefully. "Could it be one of the poems you wrote? If it is I would like to hear it." She shielded her eyes with her hand and turned away for a moment, a caricature of a shy maiden in a squat wrestler's body. Then she struggled with herself and started the poem in a weak voice, but continued, louder and louder.

I dare not ask a kiss,

I dare not beg a smile,

Lest having that, or this,

I might grow proud the while.

No, no, the utmost share

Of my desire shall be

Only to kiss the air

That lately did kiss thee.

She almost cried the last words aloud, then turned and fled to the far side of the room and stood with her face against the wall. Langli groped for the right words. The poem was good, whether she had written it herself or copied it he did not know nor did it matter. It said what she wanted to say.

"That's beautiful," he told her. "A really beautiful poem "

Before he could finish she ran, feet slapping hard against the floor, across the room and knelt beside his bed. Her solid, powerful arms were about him and her face against his, buried in the pillow. He could feel the tear-wetness of her cheeks against his own and her muffled voice in his ear.

"I knew you would come, I know who you are, because you had to come from far away like a knight in the poems riding a horse to save me. You knew I needed you. My father, I, the only Family left, I must marry one of The People. It has been done before. Ugly, stupid, I hate them, the brightest, we tried to teach him to read, he couldn't, stupid. But you came in time. You are The Family, you will take mec."

The words died away and her lips found his, urgent and strong with desire, and when he held her shoulders and tried to push her away his exoskeleton whined. with the effort but she did not move.

Finally, exhausted, she released him and pushed her face deep into the pillow again. He stood, swaying, bracing him self on the back of a chair. When he spoke it was with sincerity as he tried to make the truth less harsh than it really was.

"Patna, listen, you must believe me. I like you, you're a wonderful, brave girl. But this just can't be. Not because I am already married, that marriage will be terminated before I return, but because of this world.

You can't leave it, and I would die if I stayed here. The adaptations your people have been forced to make to survive must be incredible. Your circulatory system alone must be completely different, your blood pressure much more than normal to get blood to your brain, with more muscles in the walls of the arteries to help pump it. Perhaps major valve changes and distribution. You can't possibly have children with anyone from off this planet. Your children would be stillborn, or die soon after birth, unfit. That is the truth, you must believe"

"Ugly, skinny, too tall, too weak, shut up!" she screeched and lashed out at him, her head still turned away.

He tried to move aside, he could not, not fast enough. Her hand slapped against his arm with a sudden explosion of pain. A sharp cracking sound.

The bitch has broken my arm, he screamed to himself, staggering, sitting down slowly. His forearm hung crookedly in the brace of the exoskeleton and how it hurt. He cradled it on his knees and fumbled through his medical supplies with his good hand. She tried to help him and he snarled at her and she went away.

Bekrnatus came in, an ax over his shoulder, while the emergency cast was hardening and Langli was giving himself a shot of painkiller, with a tranquilizer for his nerves.

"What is wrong with your arm?" Bekrnatus asked, dropping the ax and falling into his couch.

"I had an accident. I will have to go get medical help from my people soon so I must talk to you now. Tell you what you need to know."

"Do that. I have questions."

"There is no time for questions." The pain was still there and he snapped the words out. "If I had the time I would explain everything slowly and in great detail so you would understand and agree. Now I will just tell you. If you want help you must pay for it. It costs a great deal to plant an MT screen on a planet as distant as this one. Medical supplies, food, energy sources, anything that we supply you will also cost a good deal. You will have to repay us."

"You have our thanks, of course."

"Not negotiable!" The pain was almost gone but he could feel the broken ends of the bones grate together when he moved. His nerves felt the same way despite the tranquilizer.

"Listen carefully and try to remember what I say. There is no pie in the sky. What you get for nothing is worth it. Out there are more planets than you could possibly count and more people on them than I could count. And the transmatter makes them all next door neighbors. Can you imagine what hell that has wreaked with culture, government, finances, down through the millennia? No, I can see by your face that you can't.

Then just think about this one bit of it. To further certain ends individuals form a co-operation, a sort of cross between a co-operative and a corporation, if those words are in any of your books. I belong to one of these called World Openers. We explore unsettled planets and occasionally contact worlds like yours that aren't on the MT net. For services rendered we demand payment in full."

Patna had come to stand by her father, silently, her arm about his thick knobbed shoulders. Her face, as she looked at Langli, was a study in hatred, contempt. Bekrnatus, a lord on his own world, would still not comprehend the realities of the galaxy outside.

"We will pay what you ask, gladly, but pay with what? We have no money, none of the resources you were asking about last night."

"You have yourselves," Langli said, emotionlessly, as the drugs took hold. "Because that is all you have it will take generations to repay your debt. You will breed faster and better, and we will help you with that. For a price, of course. We have operations on heavy gravity worlds that must be supervised. Automatic machinery can't do everything. And there are others who can use workers of your type as well"

"You come to enslave us, imprison us!" Bekrnatus roared. "To make free men into beasts of burden. Never!"

He grabbed up the ax from the floor and climbed to his feet, swinging it high. Langli was ready. His gun snapped just once and the explosion shook the room as a great pit was blown from the stone wall behind Bekrnatus.

"Just imagine what that would have done to you. Now sit down and don't be foolish. I will kill you to save my own life, be sure of that. We can't imprison you because you are in prison already on this high G world. The force that pulls you down, that makes things fall when dropped.

This force is weaker on other worlds. I can leave and seal the transmatter and that will be the end of it. If that is what you really wish. The choice is yours to make." He waved the gun at Patna. "Now open that door."

Bekrnatus stood, the ax dangling forgotten from his hand; the world he knew had changed, everything changed. Langli struggled his pack to one shoulder and waved Patna aside. He moved slowly toward the door.

"I will return and you can tell me your decision then."

Patna called to him as he went out, fighting down her loathing. "The transmatter, when will we get to use it? To see the wonders of other worlds?"

"Never in your lifetime. Use of the MT is granted only when all the debts are paid." He had to say it because the sooner she faced the truth the better she would adjust. "And you will be occupied elsewise. Intelligent operators will be needed, not strong backs. Yours is the only womb from which intelligence may spring on this world. Keep it busy."

He hobbled away until he was clear of the buildings, then gratefully set the pack down. It was too much of a burden to take back to the transmatter. He triggered the destruct and went on while it burned fiercely behind him. Expensive equipment, but it would go on the bill.

They would choose to accept and pay; they really did not have much of a choice. It would be for their benefit. Not so much now, but in the long run. The two squat figures were still in the doorway looking after him and he turned quickly away.

What did they expect, charity? The universe was uncharitable. You had to pay for what you took from it. That was a natural law that could not be broken.

And he was doing his job, that was all.

It was just a job.

He was helping them?

Wasn't he?

Stumbling, sweating, and gasping, he hurried to be away from this place.
