It made sense. Interstellar was new and they wanted him on the ship because he was a trained observer. They wanted facts, not gibberish. But to ask a man to give up two years of his life—well, that was asking a lot. Two years in a sardine can. Still, it had an appeal Keith Ellason knew he couldn't deny, a newsman's joy of the clean beat, a planetary system far afield, a closeup view of the universe, history in the first trip." Weblor I Weblor I had taken off on the first trip to Antheon five years before with a thousand families, reached the planet with less than five hundred surviving colonists. Upon the return to Earth a year later, the crew's report of suffering and chaos during the year's outgoing voyage was twisted, distorted and fragmentary. Ellason remembered it well. The decision of Interstellar was that the colonists started a revolution the halfway point. It ended with passengers engaging in open warfare with each other and the crew. Sessions was lucky to escape with his "The second trip is history," Rexroad said. "And a puzzle." "If I return," said Ellason. Captain Branson and his fifty crewmen want to return as badly as you on your return trip on the Weblor II ." Being a Nilly is important, probably as important as running the ship, and I think it is this thought that keeps us satisfied, willing to be what we are. The Weblor II had been built in space, as had its predecessor, the Weblor I which would open distant vistas to colonization, reducing the hollow spike, the ship would never land anywhere, but would circle Antheon as it circled Earth, shuttling its cargo and passengers to the be the home for three thousand persons outward bound, only the crew on the return trip. It was equipped with every conceivable facility was caught and whisked away. strictly from the observer viewpoint. There will be no story for Transworld at the end." "Let me put it differently. Let me say that you will not understand why I say that until the journey ends." He smiled. "Perhaps I shouldn't have mentioned it." a year, just as there were homes like it for three thousand others, except that the family rooms would be larger. His quarters were near the front of the spike near the officers' quarters. He felt rather than heard the dull rumble. It was a sound he knew would be with him for two years—one year going and one year returning. He looked at his watch, picked up his notebook and made an entry. The ship right now would be slipping ever so slowly away from Earth. He got up. He'd have to go forward to the observation dome to see that. Last view of Earth for two years. The penetration of space by large groups is the coming out from under the traditions of thousands of years, and as these planet-orginated rules fall away, the floundering group seeks a new control, for they was significant that all en route had passed stability tests, and that Weblor I ? They had passed stability tests too. This, then, was what happened when you took three thousand strangers and stuck them in a can for a year. When Ellason saw Branson about it, the captain said, "Of course I realize it takes only a little thing like this to set things off. I looking at the stars from the observation dome, walking down the same knows we try to vary it as much as we can. Space creates rough edges. But the point is, we know all this, and knowing it, we shouldn't let it happen. We've got to find that thief." Interstellar asked me to go along. But what use am I now? Where am I going to get seeds like those? Do you know how long it took me to collect them? They're not ordinary seeds, Mr. Ellason." return in the interests of the Antheon colony and of humanity. watchful and accusing. To men unused to it, such a sight numbs, compresses, stultifies. He introduces a countermeasure, proof he exists, which is any overt act, sometimes violent. On the forty-fifth day June Failright, the young wife of one of the passenger meteorologists, ran screaming down one of the long corridors of the Third Quadrant. She told the captain she had been attacked in "I sympathize," Branson said, "but it is up to each quadrant to deal The group left in a surly mood. suppose I assign the crew to patrol duties, the culprit isn't caught, the crew's doing in the first place."

He has to be somewhere aboard." each of the quadrants was named to serve under him. Each of these men in turn selected five others from his own group. Those assembled waited in the hall while each team of six inspected the compartments of the others. These compartments were then locked, everyone returned to his compartment, and the larger search was conducted. It took twenty hours. No mask was found. No mask, no case, no money, no man. At another assembly the following day it was decided to make the escaped. the corridors—eight on at a time.

Just let him make so much as a move." fiercely than ever. "Without a trial?" "Oh, there'll be a trial, Mr. Ellason, but you don't think any jury'd let him live after all the things he's done, do you?" and then. It was a long trial—from the 220th to the 241st day—and there didn't seem to be much doubt about the outcome, for Critten didn't help his own cause during any of it. "Sure," Critten said. "You colonists got the easy life as passengers, just sitting around. I had to work my head off keeping records for you lazy bastards." The verdict was, of course, death. It was all duly recorded in Keith Ellason's notebooks. Dying is easy for a Nilly. Especially if it's arranged for beforehand, which it always is. The Weblor II was only one day out of orbit when Captain Branson sent lives." "Let me get this straight. Interstellar thought that it was idleness and boredom that caused the killings on the Weblor I Critten nodded. "When great numbers are being transported, they are apt they told me they'd use it on other trips to Antheon." "Naturally." "We removed the charges before the guns were used." "He'll get it back when he's shuttled to Antheon. And all the other "Gave them something to do," Branson said. "Every time things got dull, I livened them up.

Yes, we're anonymous, nameless, we Nillys, for that's what we call each other, and are a theme, with variations, in the endless stretches dying once a trip when the time is ripe, antidote to boredom, and we'll ply our trade, our little tragedies, on a thousand ships bringing humanity to new worlds.
