traveling from star to star! [Transcriber's Note: This etext was produced from Extensive research did not uncover any evidence that the U.S. copyright on this publication was renewed.] Sure I'm a Nilly, and I've died seven times, always in the blackness of the outer reaches, and I'm not alone, although there aren't very many of us, never were. 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 the making. Interstellar Chief Rexroad knocked the dottle from his pipe in a tray, saying, "Transworld Press is willing to let you have a leave of abscence, if you're interested." The 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 to arm themselves." "The second trip is history," Rexroad said. "And a puzzle." Ellason nodded. "The ship disappeared." "Yes. We gave control to the colonists." "Assuming no accident in space," Phipps said, "it was a wrong decision. reporting. We'll evaluate it on your return." "If I return," said Ellason. on your return trip on the Weblor II Being a Nilly is important, probably as important as running the ship, which would open distant vistas to colonization, reducing the shoulder-to-shoulder pressure of a crowded solar system. A gigantic, hollow spike, the ship would never land anywhere, but would circle Antheon as it circled Earth, shuttling its cargo and passengers to the promised land, the new frontier. A space-borne metropolis, it would be the home for three thousand persons outward bound, only the crew on the return trip. It was equipped with every conceivable facility and comfort—dining rooms, assembly hall, individual and family Transworld at the end." Ellason was startled. While he had considered the possibility, he had not dwelt on it. Now it loomed large in his mind. "I don't understand, Captain Branson. It seems to me—" "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." Ellason left the captain's quarters with an odd taste in his mouth. Now 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 are humanity adrift, rudderless, for whom the stars are no longer stability tests too. This, then, was what happened when you took three thousand strangers and stuck them in a can for a year. tired face and sad eyes. He said, "Now what am I going to Antheon for? I could only take along so much baggage and I threw out some 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. On the thirty-fourth day a witness turned up who said he had seen a 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 the ship. Ellason was present when a delegation from the Third Quadrant called on Captain Branson, demanding action. Branson remained seated behind his desk, unperturbed, saying, "I have Antheon." The group left in a surly mood. As a Nilly, I knew that space breeds hate. There is a seed of it was ready for ripening. Raymond Palugger was killed in the ship's hospital on the sixty-first day. Palugger, a Fourth Quadrant passenger, had complained of feeling ill, had been hospitalized with a diagnosis of ileus. He had put his nine tomorrow morning in the auditorium. I will speak to you all then." Faces were angry, tongues were sharp at the meeting, eyes suspicious 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. We Nillys know about hate and about violence. We know too that where death. During sleep time on the seventy-ninth day Barbara Stoneman, awakened by a strange sound, sat up in the bed of her compartment to find a the corridors—eight on at a time. Ellason observed that for the first time the passengers seemed relaxed. retreating figure. Red Mask was seen again on the 120th day, on the 135th day, and the 157th day. He was seen, shot at, but not hit. He was also unable to commit any crime. We've got him on the run, the colonists said. of themselves. A special congratulatory message from Captain Branson appeared one day in the Bulletin newsletter. The colonists settled down to living out the rest of the voyage until the landing on Antheon. But on the 170th day calamity struck. Red Mask appropriated one of the stunners, made his way down one whole corridor section in Quadrant Two, leaving disorder behind. Ellason interviewed as many victims as he could, noted it all in It was the same with others. "The man's insane, Mr. Ellason. Positively insane." Many people said it. The council issued orders that all passengers from now on would be fiercely than ever. "Without a trial?" the escape chutes. Does that answer your question?" "Threw it away?" Tarper and the crowd were incredulous. "Sure," Critten said. "You colonists got the easy life as passengers, disposed of his body through a chute. 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 put in. "Interstellar wanted an accurate picture of this. If it worked, they told me they'd use it on other trips to Antheon." "He'll get it back when he's shuttled to Antheon. And all the other items will be returned. They're all tagged with their owner's names. Captain Branson will say they were found somewhere on the ship. You see, I was a liar." "The colonists will never know the truth," Branson went on. "There will be other ships outward bound." 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 of deep space, objects of hatred and contempt, professional heels, 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.
