The message machine whistled shrilly, and Enoch Wallace put away the book in which he had been writing and got up from his desk. He walked across the room to the whistling machine. He punched a button and shoved a key and the whistling stopped.
The machine built up its hum and the message began to form on the plate, faint at first and then becoming darker until it stood out clearly.
It read:
NO. 406301 TO STATION 18327. TRAVELER AT 16097.38. NATIVE THUBAN VI. NO
BAGGAGE. NO. 3 LIQUID TANK. SOLUTION 27. DEPART FOR STATION 12892 AT
16439.16.
CONFIRM.
Enoch glanced up at the great galactic chronometer hanging on the wall.
There was almost three hours to go.
He touched a button, and a thin sheet of metal bearing the message protruded from the side of the machine. Beneath it the duplicate fed itself into the record file. The machine chuckled and the message plate was clear once more and waiting.
Enoch pulled out the metal plate, threaded the holes in it through the double filing spindle and then dropped his fingers to the keyboard and typed: NO. 406301 RECEIVED. CONFIRM MOMENTARILY. The message came into being on the plate and he left it there.
Thuban VI? Had there been, he wondered, one of them before? As soon as he got the chores done, he would go to the filing cabinet and check.
It was a liquid tank case and those, as a rule, were the most uninteresting of all. They usually were hard ones to strike up a conversation with, because too often their concept of language was too difficult to handle. And as often, too, their very thinking processes proved too divergent to provide much common ground for communication.
Although, he recalled, that was not always true. There had been that tank traveler several years ago, from somewhere in Hydra (or had it been the Hyades?), he'd sat up the whole night with and almost failed of sending off on time, yarning through the hours, their communication (you couldn't call it words) tumbling over one another as they packed into the little time they had a lot of fellowship and, perhaps, some brotherhood.
He, or she, or it-they'd never got around to that- had not come back again. And that was the way it was, thought Enoch; very few came back. By far the greater part of them were just passing through.
But he had he, or she, or it (whichever it might be) down in black and white, as he had all of them, every single blessed one of them, down in black and white. It had taken him, he remembered, almost the entire following day, crouched above his desk, to get it written down; all the stories he'd been told, all the glimpses he had caught of a far and beautiful and tantalizing land (tantalizing because there was so much of it he could not understand), all the warmth and comradeship that had flowed between himself and this misshapen, twisted, ugly living being from another world. And any time he wished, any day he wished, he could take down the journal from the row of journals and relive that night again. Although he never had. It was strange, he thought, how there was never time, or never seemed to be the time, to thumb through and reread in part what he'd recorded through the years.
He turned from the message machine and rolled a No. 3 liquid tank into place beneath the materializer, positioning it exactly and locking it in place. Then he pulled out the retracting hose and thumbed the selector over to No. 27. He filled the tank and let the hose slide back into the wall.
Back at the machine, he cleared the plate and sent off his confirmation that all was ready for the traveler from Thuban, got back double confirmation from the other end, then threw the machine to neutral, ready to receive again.
He went from the machine to the filing cabinet that stood next to his desk and pulled out a drawer jammed with filing cards. He looked and Thuban VI was there, keyed to August 22, 1931. He walked across the room to the wall filled with books and rows of magazines and journals, filled from floor to ceiling, and found the record book he wanted. Carrying it, he walked back to his desk.
August 22, 1931, he found, when he located the entry, had been one of his lighter days. There had been one traveler only, the one from Thuban VI. And although the entry for the day filled almost a page in his small, crabbed writing, he had devoted no more than one paragraph to the visitor.
Came today [it read] a blob from Thuban VI. There is no other way in which one might describe it. It is simply a mass of matter, presumably of flesh, and this mass seems to go through some sort of rhythmic change in shape, for periodically it is globular, then begins to flatten out until it lies in the bottom of the tank, somewhat like a pancake. Then it begins to contract and to pull in upon itself, until finally it is a ball again. This change is rather slow and definitely rhythmic, but only in the sense that it follows the same pattern. It seems to have no relation to time. I tried timing it and could detect no time pattern. The shortest period needed to complete the cycle was seven minutes and the longest was eighteen. Perhaps over a longer period one might be able to detect a time rhythm, but I didn't have the time. The semantic translator did not work with it, but it did emit for me a series of sharp clicks, as if it might be clicking claws together, although it had no claws that I could see. When I looked this up in the pasimology manual I learned that what it was trying to say was that it was all right, that it needed no attention, and please leave it alone. Which I did thereafter.
And at the end of the paragraph, jammed into the little space that had been left, was the notation: See Oct. 16, 1931.
He turned the pages until he came to October 16 and that had been one of the days, he saw, that Ulysses had arrived to inspect the station.
His name, of course, was not Ulysses. As a matter of fact, he had no name at all. Among his people there was no need of names; there was other identifying terminology which was far more expressive than mere names. But this terminology, even the very concept of it, was such that it could not be grasped, much less put to use, by human beings.
"I shall call you Ulysses," Enoch recalled telling him, the first time they had met. "I need to call you something."
"It is agreeable," said the then strange being (but no longer strange).
"Might one ask why the name Ulysses?"
"Because it is the name of a great man of my race."
"I am glad you chose it," said the newly christened being. "To my hearing it has a dignified and noble sound and, between the two of us, I shall be glad to bear it. And I shall call you Enoch, for the two of us shall work together for many of your years."
And it had been many years, thought Enoch, with the record book open to that October entry of more than thirty years ago. Years that had been satisfying and enriching in a way that one could not have imagined until it had all been laid out before him.
And it would go on, he thought, much longer than it already had gone on-for many centuries more, for a thousand years, perhaps. And at the end of that thousand years, what would he know then?
Although, perhaps, he thought, the knowing was not the most important part of it.
And none of it, he knew, might come to pass, for there was interference now. There were watchers, or at least a watcher, and before too long whoever it might be might start closing in. What he'd do or how he'd meet the threat, he had no idea until that moment came. It was something that had been almost bound to happen. It was something he had been prepared to have happen all these years. There was some reason to wonder, he knew, that it had not happened sooner.
He had told Ulysses of the danger of it that first day they'd met. He'd been sitting on the steps that led up to the porch, and thinking of it now, he could remember it as clearly as if it had been only yesterday.
