Although, if it were here, there would he carnivores as well - and, for the love of God, what had he fallen into? Why hadn't he given more thought to the possibility that something like this might happen, that he would not, necessarily, automatically go back to present time, but might be shunted off into another time? And why, just as a matter of precaution, hadn't he armed himself before he left? There were high-caliber guns in the library and he could have taken one of them and a few boxes of ammunition if he had just thought about it.

He had failed to recognize the possibility of being dumped into a place like this, he admitted, because he had been thinking about what he wanted to happen, to the exclusion of all else, using shaky logic to convince himself that he was right. His wishful thinking, he now knew, had landed him in a place no sane man would choose.

He was back in the age of dinosaurs and there wasn't any house. He probably was the only human on the planet, and if his luck held out, he might last a day or two, but probably not much more than that. He knew he was going off the deep end again, thinking as illogically as he had been when he launched himself into the time rift. There might not be that many carnivores about, and if a man was observant and cautious and gave himself a chance to learn, he might be able to survive. Although the chances were that he was stuck here. There could be little hope that he could find another rift in time, and even if he did, there would be no assurance that it would take him to anything better than this. Perhaps, if he could find the point where he had emerged into this world, he might have a chance to locate the rift again, although there was no guarantee that the rift was a two-way rift. He stopped and looked around, but there was no way to know where he had first come upon this place. The landscape all looked very much the same.

The ankylosaurus, he saw, had come a little out of the shrub thicket and was nibbling quite contentedly at the ground cover. Turning his back upon it, he went trudging up the hill.

Before he reached the crest, he turned around again to have a look. The ankylosaurus was no longer around, or perhaps he did not know where to look for it. Down in the swale that had been the alder swamp where Underwood and Charlie had bagged the woodcock, a herd of small reptiles were feeding, browsing off low-growing shrubs and ground cover.

Along the skyline of the hill beyond which the herd was feeding. a larger creature lurched along on its hind legs, its body slanted upright at an angle, the shriveled forearms dangling at its side, its massive, brutal head jerking as it walked. The herd in the swale stopped their feeding, heads swiveling to look at the lurching horror. Then they ran, racing jerkily on skinny hind legs, like a flock of outsize, featherless chickens racing for their lives.

Latimer turned again and walked toward the top of the hill. The last slope was steep, steeper than he remembered it had been on that other, safer world. He was panting when he reached the crest, and he stopped a moment to regain his breath. Then, when he was breathing more easily, he turned to look toward the south.

Half-turned, he halted, amazed at what he saw - the last thing in the world that he had expected to see. Sited in the valley that lay between the hill on which he stood and the next headland to the south, was a building. Not a house, but a building. It stood at least thirty stories high and looked like an office building, its windows gleaming in the sun.

He sobbed in surprise and thankfulness, but even so, he did not begin to run toward it, but stood for a moment looking at it, as if he must look at it for a time to believe that it was there. Around it lay a park of grass and tastefully planted trees. Around the park ran a high wire fence and in the fence at the foot of the hill closest to him was a gate, beside which was a sentry box. Outside the sentry box stood two men who carried guns.

Then he was running, racing recklessly down the hill, running with great leaps, ducking thickets of shrubs. He stubbed his toe and fell, pinwheeling down the slope. He brought up against a tree and, the breath half-knocked out of him, got to his feet, gasping and wheezing. The men at the gate had not moved, but he knew that they had seen him; they were gazing up the hill toward him.

Moving at a careful, slower pace, he went on down the hill. The slope leveled off and he found a faint path that he followed toward the gate.

He came up to the two guards and stopped.

'You damn fool,' one of them said to him. 'What do you think you're doing, going out without a gun? Trying to get yourself killed?

'There's been an old Tyranno messing around here for the last several days,' said the other guard. 'He was seen by several people. An old bastard like that could go on the prod at the sight of you and you wouldn't have a chance.

'The first guard jerked his rifle toward the gate. 'Get in there,' he said.

'Be thankful you're alive. If I ever catch you going out again without a gun, I'll turn you in, so help me.

'Thank you, sir,' said Latimer.

He walked through the gate, following a path of crushed shells toward the front entrance of the office building. But now that he was there, safe behind the fence, the reaction began setting in. His knees were wobbly and he staggered when he walked. He sat down on a bench beneath a tree. He found that his hands were shaking and he held them hard against his thighs to stop the trembling.

How lucky could one get? He asked himself. And what did it mean? A house in the more recent past, an office building in this place that must be millions of years into the past. There had not been dinosaurs upon the earth for at least sixty million years. And the rift? How had the rift come about? Was it something that could occur naturally, or had it come about because someone was manipulating time? Would such rifts come when someone, working deliberately, using techniques of which there was no public knowledge, was putting stress upon the web of time? Was it right to call time a web? He decided that it made no difference, that the terminology was not of great importance.

An office building, he thought. What did an office building mean? Was it possible that he had stumbled on the headquarters of the project/conspiracy/program that was engaged in the trapping of selected people in the past? Thinking of it, the guess made Sense. A cautious group of men could not take the chance of operating such an enterprise in present time, where it might he nosed out by an eager-beaver newsman or a governmental investigation or by some other means. Here, buried in millions of years of time, there would be little chance of someone unmasking it.

Footsteps crunched on the path and Latimer looked up. A man in sports shirt and flannels stood in front of him.

'Good morning, sir,' said Latimer.

The man asked, 'Could you be David Latimer, by any chance?

'I could be, said Latimer.

'I thought so. I don't remember seeing you before. And I was sure I knew everyone. And the guards reported...

'I arrived only an hour or so ago.

'Mr Gale wanted to see you as soon as you arrived.

'You mean you were expecting me?

'Well, we couldn't be absolutely sure,' said the other. 'We are glad you made it.

Latimer got off the bench and the two of them walked together to the front entrance, climbed the steps, and went through the door. They walked through a deserted lounge, then into a hallway flanked by numbered doors with no names upon them. Halfway down the hall, the man with Latimer knocked at one of the doors.

'Come in,' a voice said.

The man opened the door and stuck his head in. 'Mr Latimer is here,' he said. 'He made it.

'That is fine,' said the voice. 'I am glad he did. Please show him in.

The man stepped aside to allow Latimer to enter, then stepped back into the hall and closed the door. Latimer stood alone, facing the man across the room.

'I'm Donovan Gale,' said the man, rising from his desk and coming across the room. He held out his hand and Latimer took it. Gale's grasp was a friendly corporate handshake.

'Let's sit over here,' he said, indicating a davenport. 'It seems to me we may have a lot to talk about.

'I'm interested in hearing what you have to say,' said Latimer.

'I guess both of us are,' said Gale. 'Interested in what the other has to say, I mean.

They sat down on opposite ends of the davenport, turning to face one another.

'So you are David Latimer,' said Gale. 'The famous painter.

'Not famous,' said Latimer. 'Not yet. And it appears now that I may never be. But what I don't understand is how you were expecting me.

'We knew you'd left Auk House.

'So that is what you call it. Auk House.

'And we suspected you would show up here. We didn't know exactly where, although we hoped that it would be nearby. Otherwise you never would have made it. There are monsters in those hills. Although, of course, we could not be really sure that you would wind up here. Would you mind telling us how you did it?

Latimer shook his head. 'I don't believe I will. Not right now, at least.

Maybe later on when I know more about your operation. And now a question for you. Why me? Why an inoffensive painter who was doing no more than trying to make a living and a reputation that might enable him to make a better living?

'I see,' said Gale, 'that you have it figured out.

'Not all of it,' said Latimer. 'And, perhaps, not all of it correctly. But I resent being treated as a bad guy, as a potential threat of some sort. I haven't got the guts or the motive to be a bad guy. And Enid, for Christ's sake. Enid is a poet. And Alice. All Alice does is play a good piano.

'You're talking to the wrong men,' Gale told him. 'Breen could tell you that, if you can get him to tell you. I'm only personnel.

'Who is Breen?

'He's head of the evaluation team.

'Those are the ones who figure out who is going to be picked up and tossed into time.

'Yes, that is the idea, crudely. There's a lot more to it than that. There is a lot of work done here. Thousands of newspapers and other periodicals to be read to spot potential subjects. Preliminary psychological determinations. Then it's necessary to do further study back on prime world. Further investigation of potential subjects. But no one back there really knows what is going on. They're just hired to do jobs now and then.

The real work goes on here.

'Prime world is present time? Your old world and mine?

'Yes. If you think, however, of prime world as present time, that's wrong.

That's not the way it is. We're not dealing with time, but with alternate worlds. The one you just came from is a world where everything else took place exactly as it did in prime world, with one exception man never evolved. There are no men there and never will be. Here, where we are now, something more drastic occurred. Here the reptiles did not become extinct.

The Cretaceous never came to an end, the Cenozoic never got started. The reptiles are still the dominant species and the mammals still are secondary.

'You're taking a chance, aren't you, in telling me all this.

'I don't think so,' said Gale. 'You're not going anywhere. There are none of us going anywhere. Once we sign up for this post, we know there's not any going back. We're stuck here. Unless you have a system...

'No system. I was just lucky.

'You're something of an embarrassment to us,' said Gale. 'in the years since the program has been in operation, nothing like this has happened at any of the stations. We don't know what to make of it and we don't quite know what to do with you. For the moment, you'll stay on as a guest. Later on, if it is your wish, we could find a place for you. You could become a member of the team.

'Right at the moment,' said Latimer, 'that holds no great attraction for me.

'That's because you aren't aware of the facts, nor of the dangers. Under the economic and social systems that have been developed in prime world, the great mass of mankind has never had it so good. There are ideological differences, of course, but there is some hope that they eventually can be ironed out. There are underprivileged areas; this cannot be denied. But one must also concede that their only hope lies in their development by free-world business interests. So-called big-business interests are the world's one hope. With the present economic structure gone, the entire world would go down into another Dark Age, from which it would require a thousand years or more to recover, if recovery, in fact, were possible at all.

'So to protect your precious economic structure, you place a painter, a poet, a musician into limbo.

Gale made a despairing gesture with his hands. 'I have told you I can't supply the rationale on that. You'll have to see Breen if he has the time to see you. He's a very busy man.

'I would imagine that he might be.

'He might even dig out the files and tell you,' said Gale. 'As I say, you're not going anywhere. You can pose no problem now. You are stuck with us and we with you. I suppose that we could send you back to Auk House, but that would be undesirable, I think. It would only upset the people who are there. As it is, they'll probably figure that you simply wandered off and got killed by a bear or bitten by a rattlesnake, or drowned in a swamp.

They'll look for you and when they don't find you, that will be it. You only got lost; they'll never consider for a moment that you escaped. I think we had better leave it at that. Since you are here and, given time, would nose out the greater part of our operation, we have no choice but to be frank with you. Understandably, however, we'd prefer that no one outside this headquarters knew.

'Back at Auk House, there was a painting of mine hanging in my room.

'We thought it was a nice touch,' said Gale. 'A sort of friendly thing to do. We could bring it here.

'That wasn't why I asked,' said Latimer. 'I was wondering - did the painting's subject have something to do with what you did to me? Were you afraid that I would go on painting pictures pointing up the failures of your precious economic structure?

Gale was uncomfortable. 'I couldn't say,' he said.

'I was about to say that if such is the case, you stand on very flimsy ground and carry a deep guilt comple.

’x'Such things are beyond me,' said Gale. 'I can't even make a comment.

'And this is all you want of me? To stand in place? To simply be a guest of all these big-hearted corporations?

'Unless you want to tell us how you got here.

'I have told you that I won't do that. Not now. I suppose if you put me to the torture...

'We wouldn't torture you,' said Gale. 'We are civilized. We regret some of the things that we must do, but we do not flinch from duty. And not the duty to what you call big-hearted corporations, but to all humankind. Man has a good thing going; we can't allow it to be undermined. We're not taking any chances. And now, perhaps I should call someone to show you to your room. I take it you got little sleep last night.

Latimer's room was on one of the topmost floors and was larger and somewhat more tastefully furnished than the room at Auk House. From a window, he saw that the conformation of the coastline was much the same as it had been at Auk House. The dirty gray of the ocean stretched off to the east and the surf still came rolling in to break upon the boulders. Some distance off shore, a school of long-necked creatures were cavorting in the water.

Watching them more closely, Latimer made out that they were catching fish.

Scattered reptilian monstrosities moved about in the hills that ran back from the sea, some of them in small herds, some of them alone. Dwarfed by distance, none of them seemed unusually large. The trees, he saw, were not a great deal different from the ones he had known. The one thing that was wrong was the lack of grass.

He had been a victim of simplistic thinking in believing, he told himself, that when he threw himself into the rift he would be carried to present time or prime world or whatever one might call it. In the back of his mind, as well, although he had not really dared to think it, had been the idea that if he could get back to the real world, he could track down the people who were involved and put a stop to it.

There was no chance of that now, he knew, and there never had been. Back on prime world, there would be no evidence that would stand up, only highly paid lackeys who performed necessary chores. Private investigators, shady operators like the Boston realtor and the Campbell who had listed Auk House for sale or rent. Undoubtedly, the sign announcing the house was available was posted only when a potential so-called customer would be driving past.

Campbell would have been paid well, perhaps in funds that could not be traced, for the part he played, offering the house and then, perhaps, driving off the car left behind by the customer. He took some risks, certainly, but they were minimal. Even should he have been apprehended, there would be no way in which he could be tied into the project. He, himself, would have had no inkling of the project. A few men in prime world would have to know, of course, for some sort of communications had to be maintained between this operations center and prime world. But the prime-world men, undoubtedly, would be solid citizens, not too well known, all beyond suspicion or reproach. They would be very careful against the least suspicion, and the communications between them and this place must be of a kind that could not be traced and would have no record.

Those few upright men, perhaps a number of hired hands who had no idea of what was being done, would he the only ones in prime world who would play any part in the project. The heart of the operation was in this building.

Here the operations were safe. There was no way to get at them. Gale had not even bothered to deny what was being done, had merely referred him to Breen for any further explanation. And Breen, should he talk with him, probably would make no denial, either.

And here he stood, David Latimer, artist, the one man outside time organization who, while perhaps not realizing the full scope of the project, still knew what was happening. Knew and could do nothing about it.

He ran the facts he had so far acquired back and forth across his mind, seeking some chink of weakness, arid there seemed to be none.

Silly, he thought, one man pitting himself against a group that held the resources of the earth within its grasp, a group at once ruthless and fanatical, that commanded as its managers the best brains of the planet, arrogant in its belief that what was good for the group was good for everyone, brooking no interference, alert to even the slightest threat, even to imagined threat.

Silly, perhaps absurdly quixotic - and, yet, what could he do? To save his own self-respect, to pay even lip service to the dignity of humanity, he must make at least a token effort, even knowing that the possibility of his accomplishing anything was very close to zero.

Say this much for them, he thought, they were not cruel men. In many ways, they were compassionate. Their imagined enemies were neither killed nor confined in noisome prisons, as had been the case with historic tyrants.

They were held under the best of circumstances, all their needs were supplied, they were not humiliated. Everything was done to keep them comfortable and happy. The one thing that had been taken from them was their freedom of choice.

But man, he thought, had fought for bitter centuries for that very freedom.

It was not something that should be lightly held or easily relinquished.

All this, at the moment, he thought, was pointless. If he should be able to do anything at all, it might not he until after months of observation and learning. He could remain in the room for hours, wallowing in his doubt an incompetency, and gain not a thing by it. It was time to begin to get acquainted with his new surroundings.

The parklike grounds surrounding the buildings were ringed by the fence, twelve feet high or more, with a four-foot fence inside it. There were trees and shrubs and beds of flowers and grass - the only grass he had seen since coming here, a well-tended greensward.

Paths of crushed shell ran among the trees and underneath them was a coolness and a quiet. A few gardeners worked in flower beds and guards stood at the distant gate, but otherwise there were few people about.

Probably it was still office hours; later on, there might be many people.

He came upon the man sitting on the bench when the walk curved sharply around a group of head-high shrubbery. Latimer stopped, and for a moment they regarded one another as if each was surprised at the appearance of the other.

Then the man on the bench said, with a twinkle in his eye, 'It seems that the two of us are the only ones who have no tasks on this beautiful afternoon. Could you be, possibly, the refugee from Auk House?

'As a matter of fact, I am,' said Latimer. 'My name is David Latimer, as if you didn't know.

'Upon my word,' said the other, 'I didn't know your name. I had only heard that someone had escaped from Auk House and had ended up with us. News travels swiftly here. The place is a rumor mill. There is so little of consequence that happens that once some notable event does occur, it is chewed to tiny shreds.

'My name, by the way, is Horace Sutton and I'm a paleontologist. Can you imagine a better place for a paleontologist to be?

'No, I can't,' said Latimer.

'Please share this bench with me,' invited Sutton. 'I take it there is nothing of immediate urgency that requires your attention.

'Not a thing,' said Latimer. 'Nothing whatsoever.

'Well, that is fine,' said Sutton. 'We can sit and talk a while or stroll around for a bit, however you may wish. Then, as soon as the sun gets over the yardarm, if by that time you're not totally disenchanted with me, we can indulge ourselves in some fancy drinking.

Sutton's hair was graying and his face was lined, but there was something youthful about him that offset the graying hair and lines.

Latimer sat down and Sutton said to him, 'What do you think of this layout?

A charming place, indeed. The tall fence, as you may have guessed, is electrified, and the lower fence keeps stupid people such as you and I from blundering into it. Although, there have been times I have been glad the fence is there. Comes a time when a carnivore or two scents the meat in here and is intent upon a feast, you are rather glad it's there.

'Do they gather often? The carnivores, I mean.

'Not as much as they did at one time. After a while, the knowledge of what to keep away from sinks into even a reptilian brain.

'As a paleontologist you study the wildlife here.

'For the last ten years,' said Sutton. 'I guess a bit less time than that.

It was strange at first; it still seems a little strange. A paleontologist, you understand, ordinarily works with bones and fossil footprints and other infuriating evidence that almost tells you what you want to know, but always falls short.

'Here there is another problem. From the viewpoint of prime world, many of the reptiles, including the dinosaurs, died out sixty-three million years ago. Here they did not die out. As a result, we are looking at them not as they were millions of years ago, but as they are after millions of additional years of evolutionary development. Some of the old species have disappeared, others have evolved into something else in which you can see the traces of their lineage, and some entirely new forms have arisen.

'You sound as if your study of them is very dedicated,' said Latimer.

'Under other circumstances, you would probably be writing a book...

'But I am writing a book,' said Sutton. 'I am hard at work on it. There is a man here who is very clever at drawing and he is making diagrams for me and there will be photographs...

'But what's the point?' asked Latimer. 'Who will publish it? When will it be published? Gale told me that no one ever leaves here, that there is no going back to prime world.

'That is right,' said Sutton. 'We are exiled from prime world. I often think of us as a Roman garrison stationed, say, on Britain's northern border or in the wilds of Dacia, with the understanding that we'll not be going back to Rome.

'But that means your book won't be published. I suppose it could be transmitted back to prime world and be printed there, but the publishing of it would destroy the secrecy of the project.

'Exactly how much do you know about the project?' Sutton asked.

'Not much, perhaps. Simply the purpose of it - the trapping of people in time - no, not time, I guess. Alternate worlds, rather.

'Then you don't know the whole of it?

'Perhaps I don't,' said Latimer.

'The matter of removing potentially dangerous personnel from prime world,

said Sutton, 'is only part of it. Surely if you have thought of it at all, you could see other possibilities.

'I haven't had time to think too deeply on it,' said Latimer. 'No time at all, in fact. You don't mean the exploitation of these other worlds?

'It's exactly what I mean,' said Sutton. 'It is so obvious, so logical.

Prime world is running out of resources. In these worlds, they lie untouched. The exploitation of the alternate worlds not only would open new resources, but would provide employment, new lands for colonization, new space for expansion. It is definitely a better idea than this silly talk you hear about going off into outer space to find new worlds that could be colonized.

'Then why all the mummery of using it to get rid of potential enemies?

'You sound as if you do not approve of this part of the project.

'I'm not sure I approve of any of it and certainly not of picking up people and stashing them away. You seem to ignore the fact that I was one of those who was picked up and stashed away. The whole thing smells of paranoia. For the love of God, the big business interests of prime world have so solid a grip on the institutions of the Earth and, in large part, on the people of the Earth, that there is no reason for the belief that there is any threat against them.

'But they do take into account,' said Sutton, 'the possibility of such threats rising in the years to come, probably based upon events that could be happening right now. They have corps of psychologists who are pursuing studies aimed against such possibilities, corps of economists and political scientists who are looking at possible future trends that might give rise to antibusiness reactions. And, as you know, they are pinpointing certain specific areas and peoples who could contribute, perhaps unwittingly, either now or in the future, to undesirable reactions. But, as I understand it, they are hopeful that if they can forestall the trends that would bring about such reactions for a few centuries, then the political, the economic, and the social climates will be so solidly committed in their favor, that they can go ahead with the exploitation of some of the alternate worlds.

They want to be sure before they embark on it, however, that they won't have to keep looking over their shoulders.

'But hundreds of years! All the people who are engaged in this project will have been long dead by then.

'You forget that a corporation can live for many centuries. The corporations are the driving force here. And, in the meantime, those who work in the project gain many advantages. It is worth their while.

'But they can't go back to Earth - back to prime world, that is.

'You are hung up on prime world,' said Sutton. 'By working in the project, you are showered with advantages that prime world could never give you.

Work in the project for twenty years, for example, and at the age of fifty - in some cases, even earlier - you can have a wide choice of retirements - an estate somewhere on Auk world, a villa on a paradise world, a hunting lodge in another world where there is a variety of game that is unbelievable. With your family, if you have one, with servants, with your every wish fulfilled. Tell me, Mr Latimer, could you do as well if you stayed on prime world? I've listed only a few possibilities; there are many others.

'Gale told me it would be possible to send me back to Auk House. So people can move around these alternate worlds, but not back to prime world?

'That is right. Supplies for all the worlds are transported to this world and from here sent out to other stations.

'But how? How is this done?

'I have no idea. There is an entire new technology involved. Once I had thought it would be matter transmitters, but I understand it's not. Certain doors exist. Doors with quote marks around them. I suppose there is a corps of elite engineers who knew, but would suspect that no one else does.

'You spoke of families.

'There are families here.

'But I didn't see ...

'The kids are in school. There aren't many people about right now. They'll be showing up at the cocktail hour. A sort of country-club routine here.

That's why I like to get up early. Not many are about. I have this park to myself.

'Sutton, you sound as if you like this setup.

'I don't mind it,' Sutton said. It's far preferable to what I had in prime world. There my reputation had been ruined by a silly dispute I fell into with several of my colleagues. My wife died. My university let me stay on in sufferance. So when I was offered a decent job...

'Not telling you what kind of job?

'Well, no, not really. But the conditions of employment sounded good and I would be in sole charge of the investigation that was in prospect. To be frank with you, I jumped at it.

'You must have been surprised.

'In fact, I was. It took a while to reconcile myself to the situation.

'But why would they want a paleontologist?

'You mean, why would money-grabbing, cynical corporations want a paleontologist?

'I guess that's what I mean.

'Look, Latimer - the men who make up the corporations are not monsters.

They saw here the need for a study of a truly unique world - a continuation of the Cretaceous, which has been, for years, an intriguing part of the planet's history. They saw it as a contribution to human knowledge. My book, when it is published, will show this world at a time before the impact of human exploitation fell upon it.

'When your book is published?

'When it is safe to make the announcement that alternate worlds have been discovered and are being opened for colonization. I'll never see the book, of course, but nevertheless, I take some pride in it. Here I have found confirmation for my stand that brought about condemnation by my colleagues.

Fuzzy thinking, they said, but they were the fuzzy thinkers. This book will vindicate me.

'And that's important? Even after you are dead?

'Of course it is important. Even after I am dead.

Sutton looked at his watch. 'I think,' he said, 'it may be time now. It just occurred to me. Have you had anything to eat?

'No,' said Latimer. 'I hadn't thought of it before. But I am hungry.

'There'll be snacks in the bar,' said Sutton. 'Enough to hold you until dinner.

'One more question before we leave,' said Latimer. 'You said the reptiles showed some evolutionary trends. In what direction? How have they changed?

'In many ways,' said Sutton. 'Bodily changes, of course. Perhaps ecological changes as well - behavioral changes, although I can't he sure of that. I can't know what their behavior was before. Some of the bigger carnivores haven't changed at all. Perhaps a bit more ability in a number of cases.

Their prey may have become faster, more alert, and the carnivores had to develop a greater agility or starve. But the most astonishing change is in intelligence. There is one species, a brand-new species so far as I know, that seems to have developed a pronounced intelligence. If it is intelligence, it is taking a strange direction. It's hard to judge correctly. You must remember that of all the stupid things that ever walked the earth, some of the dinosaurs ranked second to none. They didn't have a lick of sense.

'You said intelligence in a strange direction.

'Let me try to tell you. I've watched these jokers for hours on end. I'm almost positive that they handle herds of herbivores - herbivorous reptiles, that is. They don't run around them like sheepdogs manage sheep, but I am sure they do control them. There are always a few of them watching the herds, and while they're watching them, the herds do no straying - they stay together like a flock of sheep tended by dogs. They move off in orderly fashion when there is need to move to a new pasture. And every once in a while, a few members of the herd with detach themselves and go ambling off to a place where others of the so-called intelligent dinosaurs are hanging out, and there they are killed. They walk in to be slaughtered. I can't get over the feeling that the herbivores are meat herds, the livestock of the intelligence species. And another thing. When carnivores roam in, these intelligent jokers shag them out of there. Not by chasing them or threatening them. Just by moving out where they can be seen. Then they sit down, and after the carnivores have looked them over, the carnivores seem to get a little jittery, and after a short time they move off.

'Hypnotism? Some sort of mental power?

'Possibly.

'That wouldn't have to be intelligence. It could be no more than an acquired survival trait.

'Somehow I don't think so. Other than watching herds and warning off carnivores - if that is what they're doing - they sit around a lot among themselves. Like a hunch of people talking. That's the impression I get, that they are talking. None of the social mannerisms that are seen among primates - no grooming, horseplay, things like that. There seems to be little personal contact - no touching, no patting, no stroking. As if none of this were needed. But they dance. Ritualistic dancing of some sort.

Without music. Nothing to make music with. They have no artifacts. They haven't got the hands that could fashion artifacts. Maybe they don't need tools or weapons or musical instruments. Apparently they have certain sacred spots. Places where they go, either singly or in small groups, to meditate or worship. I know of one such place; there may be others. No idols, nothing physical to worship. A secluded spot. Seemingly a special place. They have been using it for years. They have worn a path to it, a path trod out through the centuries. They seem to have no form of worship, no rituals that must be observed. They simply go and sit there. At no special time. There are no Sundays in this world. I suspect they go only when they feel the need of going.

'It is a chilling thought,' said Latimer.

'Yes, I suppose it is.

He looked at his watch again. 'I am beginning to feel the need of that drink,' he said. 'How about you?

'Yes' said Latimer, 'I could do with one.

And now, he told himself, he had a few more of the answers. He knew how the staff at Auk House was changed, where the supplies came from. Everything and everyone, apparently, was channeled and routed from this operations center. Prime world, from time to time, furnished supplies and personnel and then the rest was handled here.

He found himself puzzled by Sutton's attitude. The man seemed quite content, bore no resentment over being exiled here. They are not monsters, he had said, implying that the men in this operation were reasonable and devoted men working in the public interest. He was convinced that someday his book would be published, according him posthumous vindication. There had been, as well, Latimer remembered, Enid's poems and Dorothy's novel.

Had the poems and the novel been published back in prime world, perhaps under pseudonyms, works so excellent that it had been deemed important that they not be lost?

And what about the men who had done the research that had resulted in the discovery of the alternate worlds and had worked out the technique of reaching and occupying them? Not still on prime world, certainly; they would pose too great a danger there. Retired, perhaps, to estates on some of the alternate worlds.

They walked around one of the clumps of trees with which the park was dotted, and from a distance Latimer heard the sound of children happy at their play.

'School is out,' said Sutton. 'Now it's the children's hour.

'One more thing,' said Latimer, 'if you don't mind. One more question. On all these other alternate worlds you mention, are there any humans native to those worlds? Is it possible there are other races of men?

'So far as I know,' said Sutton, 'man rose only once, on prime world. What I have told you is not the entire story, I imagine. There may be much more to it. I've been too busy to attempt to find out more. All I told you are the things I have picked up in casual conversation. I do not know how many other alternate worlds have been discovered, nor on how many of them stations have been established. I do know that on Auk world there are several stations other than Auk House.

'By stations, you mean the places where they put the undesirables.

'You put it very crudely, Mr Latimer, but yes, you are quite right. On the matter of humans arising elsewhere, I think it's quite unlikely. It seems to me that it was only by a combination of a number of lucky circumstances that man evolved at all. When you take a close look at the situation, you have to conclude that man had no right to expect to evolve. He is a sort of evolutionary accident.

'And intelligence? Intelligence rose on prime world, and you seem to have evidence that it has risen here as well. Is intelligence something that evolution may be aiming at and will finally achieve, in whatever form on whatever world? How can you be sure it has not risen on Auk world? At Auk House, only a few square miles have been explored. Perhaps not a great deal more around the other stations.

'You ask impossible questions,' said Sutton shortly. 'There is no way I can answer them.

They had reached a place from which a full view of the headquarters building was possible and now there were many people - men and women walking about or sunning themselves, stretched out on the grass, people sitting on terraces in conversational groups, while children ran gaily, playing a childish game.

Sutton, who had been walking ahead of Latimer, stopped so quickly that Latimer, with difficulty, averted bumping into him.

Sutton pointed. 'There they are,' he said.

Looking in the direction of the pointing finger, Latimer could see nothing unusual. 'What? Where?' he asked.

'On top the hill, just beyond the northern gate.

After a moment Latimer saw them, a dozen squatting creatures on top of the hill down which, a few hours ago, he had run for the gate and safety. They were too distant to be seen clearly, but they had a faintly reptilian look and they seemed to be coal-black, but whether naturally black or black because of their silhouetted position, he could not determine.

'The ones I told you about,' said Sutton. 'It's nothing unusual. They often sit and watch us. I suspect they are as curious about us as we are about them.

'The intelligences?' asked Latimer.

'Yes, that is right,' said Sutton.

Someone, some distance off, cried in a loud voice - no words that Latimer could make out, but a cry of apprehension, a bellow of terror. Then there were other cries, different people taking up the cry.

A man was running across the park, heading for its northeast corner, running desperately, arms pumping back and forth, legs a blur of scissoring speed. He was so far off that he looked like a toy runner, heading for the four-foot fence that stood inside the higher fence. Behind him were other runners, racing in au attempt to head him off and pull him down.

'My God, it's Breen,' gasped Sutton. His face had turned to gray. He started forward, in a stumbling run. He opened his mouth to shout, but all he did was gasp.

The running man came to the inner fence and cleared it with a leap. The nearest of his pursuers was many feet behind him.

Breen lifted his arms into the air, above his head. He slammed into the electrified fence. A flash blotted him out. Flickering tongues of flame ran along the fence - bright and sparkling, like the flaring of fireworks. Then the brightness faded and on the fence hung a black blot that smoked greasly and had a fuzzy, manlike shape.

A hush, like an indrawn breath, came upon the crowd. Those who had been running stopped running and, for a moment, held their places. Then some of them, after that moment, ran again, although some of them did not, and the voice took up again, although now there was less shouting.

When he looked, Latimer saw that the hilltop was empty; the dinosaurs that had been there were gone. There was no sign of Sutton.

So it was Breen, thought Latimer, who hung there on the fence. Breen, head of the evaluation team, the one man, Gale had said, who could tell him why he had been lured to Auk House. Breen, the man who pored over psychological evaluations, who was acquainted with the profile of each suspected personage, comparing those profiles against economic charts, social diagnostic indices, and God knows what else, to enable him to make the decision that would allow one man to remain in prime world as he was, another to be canceled out.

And now, thought Latimer, it was Breen who had been canceled out, more effectively than he had canceled any of the others.

Latimer had remained standing where he had been when Sutton and he had first sighted the running Breen, had stood because he could not make up his mind what he should do, uncertain of the relationship that he held or was expected to assume with those other persons who were still milling about, many of them perhaps as uncertain as he of what they should do next.

He began to feel conspicuous because of just standing there, although at the same time he was certain no one noticed him, or if they did notice him, almost immediately dismissed him from their thoughts.

He and Sutton had been on their way to get a drink when it had all happened, and thinking of that, Latimer realized he could use a drink. With this in mind, he headed for the building. Few noticed him, some even brushing against him without notice; others spoke noncommittal greetings, some nodded briefly as one nods to someone of whose identity he is not certain.

The lounge was almost empty. Three men sat at a table in one corner, their drinks before them; a woman and a man were huddled in low-voiced conversation on a corner of a davenport; another man was at the self-service bar, pouring himself a drink.

Latimer made his way to the bar and picked up a glass.

The man who was there said to him, 'You must be new here; I don't remember seeing you about.

'Just today,' said Latimer. 'Only a few hours ago.

He found the Scotch and his brand was not among the bottles. He selected his second choice and poured a generous serving over ice. There were several trays of sandwiches and other snack items. He found a plate, put two sandwiches on it.

'What do you make of Breen?' asked the other man.

'I don't know,' said Latimer. 'I never met the man. Gale mentioned him to me.

"Three,' said the other man. 'Three in the last four months. There is something wrong.

'All on the fence?

'No, not on the fence. This is the first on the fence. One jumped, thirteen stories. Christ, what a mess! The other hanged himself.

'The man walked off and joined another man who had just come into the lounge. Latimer stood alone, plate and glass in hand. The lounge still was almost empty. No one was paying the slightest attention to him. Suddenly he felt a stranger, unwanted. He had been feeling this all the time, he knew, but in the emptiness of the lounge, the feeling of unwantedness struck with unusual force. He could sit down at a table or in one of a group of chairs or on the end of an unoccupied sofa, wait for someone to join him. He recoiled from the thought. He didn't want to meet these people, talk with them. For the moment, he wanted none of them.

Shrugging, he put another sandwich on the plate, picked up the bottle, and filled his glass to the top. Then he walked out into the hallway and took the elevator to his floor.

In his room, he selected the most comfortable chair and sat down in it, putting the plate of sandwiches on a table. He took a long drink and put down the glass.

'They can all go to hell,' he told himself.

He sensed his fragmented self pulling back together, all the scattered fragments falling back into him again, making him whole again, his entire self again. With no effort at all, he wiped out Breen and Sutton, the events of the last hours, until he was simply a man seated comfortably in his room.

So great a power, he thought, so great and secret. Holding one world in thrall, planning to hold others. The planning, the foresight, the audacity.

Making certain that when they moved into the other worlds, there would be no silly conservationists yapping at their heels, no environmentalist demand jug environmental impact statements, no deluded visionaries crying out in protest against monopolies. Holding steadily in view the easy business ethic that had held sway in that day when arrogant lumber barons had built mansions such as Auk House.

Latimer picked up the glass and had another drink. The glass, he saw, was less than half full. He should have carried off the bottle, he thought; no one would have noticed. He reached for a sandwich and munched it down, picked up a second one. How long had it been since he had eaten? He glanced at his watch and knew, even as he did, that the time it told might not be right for this Cretaceous world. He puzzled over that, trying to figure out if there might be some time variance between one world and another. Perhaps there wasn't - logically there shouldn't be - but there might be factors ... he peered closely at the watch face, but the figures wavered and the hands would not stay in line. He had another drink.

He woke to darkness, stiff and cramped, wondering where he was. After a moment of confusion, he remembered where he was, all the details of the last two days tumbling in upon him, at first in scattered pieces, then subtly arranging themselves and interlocking into a pattern of reality.

He had fallen asleep in the chair. The moonlight pouring through the window showed the empty glass, the plate with half a sandwich still upon it, standing on the table at his elbow. The place was quiet; there was no noise at all. It must be the middle of the night, he thought, and everyone asleep. Or might it be that there was no one else around, that in some strange way, for some strange reason, the entire headquarters had been evacuated, emptied of all life? Although that, he knew, was unreasonable.

He rose stiffly from the chair and walked to the window. Below him, the landscape was pure silver, blotched by deep shadows. Somewhere just beyond the fence, he caught a sense of movement, but was unable to make out what it was. Some small animal, perhaps, prowling about. There would he mammals here, he was sure, the little skitterers, frightened creatures that were hard-pressed to keep out of the way, never having had the chance to evolve as they had back in prime world when something had happened millions of years before to sweep the world clean of its reptilian overlords, creating a vacuum into which they could expand.

The silver world that lay outside had a feel of magic - the magic of a brand-new world as yet unsullied by the hand and tools of men, a clean place that had no litter in it. If he went out and walked in it, he wondered, would the presence of himself, a human who had no right to be there, subtract something from the magic?

Out in the hall, he took the elevator to the ground floor. Just off the corridor lay the lounge and the outer door opened from the lounge. Walking softly, although he could not explain why he went so softly, for in this sleeping place there was no one to disturb, he went into the lounge.

As he reached the door, he heard voices and, halting in the shadow, glanced rapidly over the room to locate the speakers. There were three of them sitting at a table in the far end of the lounge. Bottles and glasses stood upon the table, but they did not seem to be drinking; they were hunched forward, heads close together, engaged in earnest conversation.

As he watched, one of them reared back in his chair, speaking in anger, his voice rising. 'I warned you,' he shouted. 'I warned Breen and I warned you, Gale. And you laughed at me.

It was Sutton who was speaking. The man was too distant and the light too dim for Latimer to recognize his features, but the voice he was sure of.

'I did not laugh at you,' protested Gale.

'Perhaps not you, but Breen did.

'I don't know about Breen or laughter,' said the third man, 'but there's been too much going wrong. Not just the three suicides. Other things as well. Miscalculations, erroneous data processing, bad judgments. Things all screwed up. Take the generator failure the other day. Three hours that we were without power, the fence without power. You know what that could mean if several big carnivores ...

'Yes, we know,' said Gale, 'but that was a mere technical malfunction.

Those things happen. The one that worries me is this fellow, Latimer. That was a pure and simple foul-up. There was no reason to put him into Auk House. It cost a hell of a lot of money to do so; a very tricky operation.

And when he got there, what happens? He escapes. I tell you, gentlemen, there are too many foul-ups. More than can be accounted for in the normal course of operation.

'There is no use trying to cover it up, to make a mystery out of it,' said Sutton. 'You know and I know what is happening, and the sooner we admit we know and start trying to figure out what to do about it, the better it will be. If there is anything we can do about it. We're up against an intelligence that may be as intelligent as we are, but in a different way.

In a way that we can't fight. Mental power against technical power, and in a case like that, I'd bet on mental power. I warned you months ago. Treat these jokers with kid gloves, I told you. Do nothing to upset them. Handle them with deference. Think kindly toward them, because maybe they can tell what you're thinking. I believe they can. And then what happens? A bunch of lunkheads go out for an afternoon of shooting and when they find no other game, use these friends of ours for casual target practice ...

'But that was months ago,' said the third man.

'They're testing,' said Sutton. 'Finding out what they can do. How far they can go. They can stop a generator. They can mess up evaluations. They can force men to kill themselves. God knows what else they can do. Give them a few more weeks. And, by the way, what particular brand of idiocy persuaded prime world to site the base of operations in a world like this?

'There were many considerations,' said Gale. 'For one thing, it seemed a safe place. If some opposition should try to move in on us ...

"You're insane,' shouted Sutton. 'There isn't any opposition. How could there he opposition?

Moving swiftly. Latimer crossed the corner of the lounge, eased his way out of the door. Looking back over his shoulder, he saw the three still sitting at the table. Sutton was shouting, banging his fist on the table-top.

Gale was shrilling at him, his voice rising over Sutton's shouting: 'How the hell could we suspect there was intelligence here? A world of stupid lizards ...

Latimer stumbled across the stone-paved terrace and went down the short flight of stone stairs that took him to the lawn. The world still was silver magic, a full moon riding in a cloudless sky. There was a softness in the air, a cleanness in the air.

But he scarcely noticed the magic and the cleanness. One thing thundered in his brain. A mistake! He should not have been sent to Auk House. There had been a miscalculation. Because of the mental machination of a reptilian intelligence on this world where the Cretaceous had not ended, he had been snatched from prime world. Although the fault, he realized, did not lie in this world, but in prime world itself - in the scheme that had been hatched to make prime world and the alternate worlds safe, safe beyond all question, for prime world's business interests.

He walked out across the sward and looked up at the northern hilltop. A row of huddled figures sat there, a long row of dumpy reptilian figures solemnly staring down at the invaders who had dared to desecrate their world.

He had wondered, Latimer remembered, how one man alone might manage to put an end to the prime-world project, knowing well enough that no one man could do it, perhaps that no conceivable combination of men could do it.

But now he need wonder no longer. In time to come, sooner or later, an end would come to it. Maybe by that time, most of the personnel here would have been transferred to Auk House or to other stations, fleeing this doomed place. It might be that in years to come, another operations center would be set up on some safer world and the project would go on. But at least some time would be bought for the human race; perhaps the project might be dropped. It already had cost untold billions. How much more would the prime-world managers be willing to put into it? That was the crux of it, he knew, the crux of everything on prime world: was it worth the cost?

He turned about to face the hilltop squarely and those who squatted there.

Solemnly, David Latimer, standing in the magic moonlight, raised an arm in salutation to them.

He knew even as he did it that it was a useless gesture, a gesture for himself rather than for those dumpy figures sitting on the hilltop, who would neither see nor know. But even so, it was important that he do it, important that he, an intelligent human, pay a measure of sincere respect to an intelligence of another species in recognition of his belief that a common code of ethics might be shared.

The figures on the hilltop did not stir. Which, he told himself, was no more than he had expected of them. How should they know, why should they care what he instinctively had tried to communicate to them, not really expecting to communicate, but at least to make some sign, if to no other than himself, of the sense of fellowship that he, in that moment, felt for them?

As he was thinking this, he felt a warmness come upon him, encompassing him, enfolding him, as when he had been a child, in dim memory, he remembered his mother tucking him snugly into bed. Then he was moving, being lifted and impelled, with the high guard fence below him and the face of the great hill sliding underneath him. He felt no fright, for he seemed to be in a dreamlike state inducing a belief, deep-seated, that what was happening was not happening and that, in consequence, no harm could come to him.

He faced the dark and huddled figures, all sitting in a row, and although he still was dream-confused, he could see them clearly. They were nothing much to look at. They were as dumpy and misshapen as they had seemed when he had seen them from a distance. Their bodies were graceless lumps, the details vague even in the bright moonlight, but the faces he never would forget. They had the sharp triangle of the reptilian skull, the cruelty of the sharpness softened by the liquid compassion of the eyes.

Looking at them, he wondered if he was really there, if he was facing them, as he seemed to be, or if he still might be standing on the greensward of the compound, staring up the hill at the huddled shapes, which now seemed to be only a few feet distant from him. He tried to feel the ground beneath his feet, to press his feet against the ground, a conscious effort to orient himself, and, try as he might, he could feel no ground beneath his feet.

They were not awesome creatures and there was nothing horrible about them - just a faint distastefulness. They squatted in their limpy row and stared at him out of the soft liquid of their eyes. And he felt - in some strange way that he could not recognize, he felt the presence of them. Not as if they were reaching out physically to touch him - fearing that if they did touch him, he would recoil from them - but in another kind of reaching, as if they were pouring into him, as one might pour water in a bottle, an essence of themselves.

Then they spoke to him, not with voice, not with words, with nothing at all that he could recognize - perhaps, he thought wildly, they spoke with that essence of themselves they were pouring into him.

'Now that we have met,' they said, 'we'll send you back again.

And he was back.

He stood at the end of the brick-paved driveway that led up to the house, and behind him he heard the damp and windy rustle of a primeval forest, with two owls chuckling throatily in the trees behind him. A few windows in the house were lighted. Great oaks grew upon the spreading lawn, and beneath the trees stood graceful stone benches that had the look of never being used.

Auk House, he told himself. They had sent him back to Auk House, not back to the grassy compound that lay inside the fence in that other world where the Cretaceous had not ended.

Inside himself he felt the yeasty churning of the essence that the squatting row of monstrosities had poured into him, and out of it he gained a knowledge and a comfort.

Policemen, he wondered, or referees, perhaps? Creatures that would monitor the efforts of those entrepreneurs who sought a monopoly of all the alternate worlds that had been opened for humans, and perhaps for many other races. They would monitor and correct, making certain that the worlds would not fall prey to the multinational financial concepts of the race that had opened them, but would become the heritage and birth-right of those few intelligent peoples that had risen on this great multiplicity of worlds, seeing to it that the worlds would be used in a wiser context than prime world had been used by humans.

Never doubting for a moment that it would or could be done, knowing for a certainty that it would come about, that in the years to come men and other intelligences would live on the paradise worlds that Sutton had told him of - and all the other worlds that lay waiting to be used with an understanding the human race had missed. Always with those strange, dumpy ethical wardens who would sit on many hilltops to keep their vigil.

Could they be trusted? he wondered, and was ashamed of thinking it. They had looked into his eyes and had poured their essence into him and had returned him here, not back to the Cretaceous compound. They had known where it was best for him to go and they would know all the rest of it.

He started up the driveway, his heels clicking on the bricks. As he came up to the stoop the door came open and the man in livery stood there.

'You're a little late,' said the butler. 'The others waited for you, but just now sat down to dinner. I'm sure the soup's still warm.

'I'm sorry,' said Latimer. 'I was unavoidably detained.

'Some of the others thought they should go out looking for you, but Mr Jonathon dissuaded them. He said you'd be all right. He said you had your wits about you. He said you would be back.

The butler closed the door behind him. 'They'll all he very happy to find you're back,' he said.

'Thank you,' said Latimer.

He walked, trying not to hurry, fighting down the happiness he felt welling up inside himself, toward the doorway from which came the sound of bright laughter and sprightly conversation.
