Another hundred years, thought Enoch. How much would he learn in another hundred years? In another thousand?

"I rest now," said the Thuban. "Nice to talk with you."

Enoch turned from the tank and picked up the block of wood. A little puddle of liquid had drained off it and lay glistening on the floor.

He carried the block across the room to one of the windows and examined it. It was heavy and black and close-grained and at one corner of it a bit of bark remained. It had been sawed. Someone had cut it into a size that would fit the tank where the Thuban rested.

He recalled an article he had read in one of the daily papers just a day or two before in which a scientist had contended that no great intelligence ever could develop on a liquid world.

But that scientist was wrong, for the Thuban race had so developed and there were other liquid worlds which were members of the galactic cofraternity. There were a lot of things, he told himself, that Man would have to unlearn, as well as things to learn, if he ever should become aware of the galactic culture.

The limitation of the speed of light, for one thing.

For if nothing moved faster than the speed of light, then the galactic transport system would be impossible.

But one should not censure Man, he reminded himself, for setting the speed of light as a basic limitation. Observations were all that Man-or anyone, for that matter-could use as data upon which to base his premises. And since human science had so far found nothing which consistently moved faster than the speed of light, then the assumption must be valid that nothing could or did consistently move faster. But valid as an assumption only and no more than that.

For the impulse patterns which carried creatures star to star were almost instantaneous, no matter what the distance.

He stood and thought about it and it still was hard, he admitted to himself, for a person to believe.

Moments ago the creature in the tank had rested in another tank in another station and the materializer had built up a pattern of it-not only of its body, but of its very vital force, the thing that gave it life. Then the impulse pattern had moved across the gulfs of space almost instantaneously to the receiver of this station, where the pattern had been used to duplicate the body and the mind and memory and the life of that creature now lying dead many light years distant. And in the tank the new body and the new mind and memory and life had taken almost instant form-an entirely new being, but exactly like the old one, so that the identity continued and the consciousness (the very thought no more than momentarily interrupted), so that to all intent and purpose the being was the same.

There were limitations to the impulse patterns, but this had nothing to do with speed, for the impulses could cross the entire galaxy with but little lag in time. But under certain conditions the patterns tended to break down and this was why there must be many stations-many thousands of them. Clouds of dust or gas or areas of high ionization seemed to disrupt the patterns and in those sectors of the galaxy where these conditions were encountered, the distance jumps between the stations were considerably cut down to keep the pattern true. There were areas that had to be detoured because of high concentrations of the distorting gas and dust.

Enoch wondered how many dead bodies of the creature that now rested in the tank had been left behind at other stations in the course of the journey it was making-as this body in a few hours' time would lie dead within this tank when the creature's pattern was sent out again, riding on the impulse waves.

A long trail of dead, he thought, left across the stars, each to be destroyed by a wash of acid and flushed into deep-lying tanks, but with the creature itself going on and on until it reached its final destination to carry out the purpose of its journey.

And those purposes, Enoch wondered-the many purposes of the many creatures who passed through the stations scattered wide in space? There had been certain instances when, chatting with the travelers, they had told their purpose, but with the most of them he never learned the purpose-nor had he any right to learn it. For he was the keeper only.

Mine host, he thought, although not every time, for there were many creatures that had no use for hosts. But the man, at any rate, who watched over the operation of the station and who kept it going, who made ready for the travelers and who sent them on their way again when that time should come. And who performed the little tasks and courtesies of which they might stand in need.

He looked at the block of wood and thought how pleased Winslowe would be with it. It was very seldom that one came upon a wood that was as black or finegrained as this.

What would Winslowe think, he wondered, if he could only know that the statuettes he carved were made of woods that had grown on unknown planets many light years distant. Winslowe, he knew, must have wondered many times where the wood came from and how his friend could have gotten it. But he had never asked. And he knew as well, of course, that there was something very strange about this man who came out to the mailbox every day to meet him. But he had never asked that, either.

And that was friendship, Enoch told himself.

This wood, too, that he held in his hands, was another evidence of friendship-the friendship of the stars for every humble keeper of a remote and backwoods station stuck out in one of the spiral arms, far from the center of the galaxy.

The word had spread, apparently, through the years and throughout space, that this certain keeper was a collector of exotic woods-and so the woods came in. Not only from those races he thought of as his friends, but from total strangers, like the blob that now rested in the tank.

He put the wood down on a table top and went to the refrigerator. From it he took a slab of aged cheese that Winslowe had bought for him several days ago, and a small package of fruit that a traveler from Sirrah X had brought the day before.

"Analyzed," it had told him, "and you can eat it without hurt. It will play no trouble with your metabolism. You've had it before, perhaps? So you haven't. I am sorry. It is most delicious. Next time, you like it, I shall bring you more."

From the cupboard beside the refrigerator he took out a small, flat loaf of bread, part of the ration regularly provided him by Galactic Central. Made of a cereal unlike any known on Earth, it had a distinctly nutty flavor with the faintest hint of some alien spice.

He put the food on what he called the kitchen table, although there was no kitchen. Then he put the coffee maker on the stove and went back to his desk.

The letter still lay there, spread out, and he folded it together and put it in a drawer.

He stripped the brown folders off the papers and put them in a pile. From the pile he selected the New York Times and moved to his favorite chair to read.

NEW PEACE CONFERENCE AGREED UPON, said the lead-off headline.

The crisis had been boiling for a month or more, the newest of a long series of crises which had kept the world on edge for years. And the worst of it, Enoch told himself, was that the most of them were manufactured crises, with one side or the other pushing for advantage in the relentless chess game of power politics which had been under way since the end of World War II.

The stories in the Times bearing on the conference had a rather desperate, almost fatalistic, ring, as if the writers of the stories, and perhaps the diplomats and all the rest involved, knew the conference would accomplish nothing-if, in fact, it did not serve to make the crisis deeper.
