A billion years up the timeline, power was flooding into the real Hammer of which this was only the partial replica. A man—or something else, perhaps a shipment of supplies—stood in the center of the real Anvil, waiting for the Hawksbill Field to enfold him and kick him back to the early Paleozoic. The effect of time-travel was very much like being hit with a gigantic hammer and driven clear through the walls of the continuum: hence the governing metaphors for the parts of the machine.
Setting up Hawksbill Station had been a long, slow job. The Hammer had knocked a pathway and had sent back the nucleus of the receiving station, first. Since there was no receiving station on hand to receive the receiving station, a certain amount of waste had occurred. It wasn’t necessary to have a Hammer and Anvil on the receiving end, except as a fine control to prevent temporal spread; without the equipment, the field wandered a little, and it was possible to scatter consecutive shipments over a span of twenty or thirty years. There was plenty of such temporal garbage all around Hawksbill Station, stuff that had been intended for original installation, but which because of tuning imprecisions in the pre-Hammer days had landed a couple of decades (and a couple of hundred miles) away from the intended site.
Despite such difficulties, they had finally sent through enough components to the master temporal site to allow for the construction of a receiving station. Then the first prisoners had gone through; they were technicians who knew how to put the Hammer and Anvil together. They had done the job. After that, outfitting Hawksbill Station had been easy.
Now the Hammer glowed, meaning that they had activated the Hawksbill Field on the sending end, somewhere up around 2028 or 2030 A. D. All the sending was done there. All the receiving was done here. It didn’t work the other way. Nobody really knew why, although there was a lot of superficially profound talk about the rules of entropy.
There was a whining, hissing sound as the edges of the Hawksbill Field began to ionize the atmosphere in the room. Then came the expected thunderclap of implosion, caused by an imperfect overlapping of the quantity of air that was subtracted from this era and the quantity that was being thrust into it. And then, abruptly, a man dropped out of the Hammer and lay, stunned and limp, on the gleaming Anvil.
He looked young, which surprised Barrett considerably. He seemed to be well under thirty. Generally, only middle-aged men were sent to Hawksbill Station. Incorrigibles, who had to be separated from humanity for the general good. The youngest man in the place now had been close to forty when he arrived. The sight of this lean, clean-cut boy drew a hiss of anguish from a couple of the men in the room, and Barrett understood the constellation of emotions that pained them.
The new man sat up. He stirred like a child coming out of a long, deep sleep. He looked around.
His face was very pale. His thin lips seemed bloodless. His blue eyes blinked rapidly. His jaws worked as though he wanted to say something, but could not find the words.
There were no harmful physiological effects to time-travel, but it could be a jolt to the consciousness. The last moments before the Hammer descended were very much like the final moments beneath the guillotine. The departing prisoner took his last look at the world of rocket transport and artificial organs, at the world in which he had lived and loved and agitated for a political cause, and then he was rammed into the inconceivably remote past on a one-way journey. It was a gloomy business, and it was not very surprising that the newcomers arrived in a state of emotional shock.
Barrett elbowed his way through the crowd. Automatically, the others made way for him. He reached the lip of the Anvil and leaned over it, extending a hand to the new man. His broad smile was met by a look of blank bewilderment.
“I’m Jim Barrett. Welcome to Hawksbill Station. Here —get off that thing before a load of groceries lands on top of you.” Wincing a little as he shifted his weight, Barrett pulled the new man down from the Anvil.
Barrett beckoned to Mel Rudiger, and the plump anarchist handed the new man an alcohol capsule. He took it and pressed it to his arm without a word. Charley Norton offered him a candy bar. The man shook it off. He looked groggy. A real case of temporal shock, Barrett thought, possibly the worst he had ever seen. The newcomer hadn’t even spoken yet.
Barrett said, “We’ll go to the infirmary and check you out. Then I’ll assign you your quarters. There’s time for you to find your way around and meet everybody later on. What’s your name?”
“Hahn. Lew Hahn.”
“I can’t hear you.”
“Hahn,” the man repeated, still only barely audible.
“When are you from, Lew?”
