not uncover any evidence that the U.S. copyright on this publication was without note. Circus "Just suppose," said Morgan, "that I did The man shifted uneasily in his seat. He was silent, staring down at his plate. Not a strange-looking man, Morgan thought. Rather ordinary, in fact. A plain face, nose a little too long, fingers a little too dainty, a suit that doesn't quite seem to fit, but all in all, a perfectly ordinary looking man. Maybe too ordinary, Morgan thought. got to believe me, Morgan. I'm lost, fan swished patiently. The man across from Morgan ran a hand through his dark hair. "There must be some other way," he said. "There has to be." "All right, let's start from the beginning again," Morgan said. "Maybe we can pin something down a little better. You say your name is Parks—right?" The man nodded. "Jefferson Haldeman Parks, if that helps any. Haldeman was my mother's maiden name." "All right. And you got into town on Friday—right?" Parks nodded. "Fine. Now go through the whole story again. What happened first?" and tried to flag down a ride." "How did you feel? I mean, was there anything strange that you noticed?" " Strange! " Parks' eyes widened. "I—I was speechless. At first I hadn't noticed too much—I was concerned with the fall, and whether I was hurt or not. I didn't really think about much Morgan nodded. "I know, I noticed. What did you do when had been no way of knowing if it would be useful, but I'd taken it on chance. I tried to use it at a newsstand first, and the man wouldn't touch it. Asked me if I thought I was the U.S. Treasury or something. When he saw that I was serious, he sent me to a money lender, a hock shop, I think he called it. So I found a place—" "Let me see the coins." Parks dropped two small gold discs on the table. They were perfectly smooth and perfectly round, tapered by wear to a thin blunt edge. There was no design on them, and no printing. Morgan looked up at the man sharply. "What did you get for these?" Parks shrugged. "Too little, I suspect. Two dollars for the small one, five for the larger." "You should have gone to a bank." "I know that now. I didn't then. Naturally, I assumed that Morgan sighed and leaned back in his chair. "Well, then what?" Parks poured some more coffee. His face was very pale, Morgan thought, and his hands trembled as he raised the cup to his lips. Fright? Maybe. Hard to tell. The man put down "First, I went to the mayor's office," he said. "I kept trying to think what anyone at home would do in my place. That seemed a good bet. I asked a policeman where it was, and then I went there." "But you didn't get to see him." and that I would have to have an appointment. She let "And you told him?" "No. I wanted to see the mayor himself. I thought that was the best thing to do. I waited for a couple of hours, until another assistant came along and told me flatly that the mayor wouldn't see me unless I stated my business first." He drew in a deep breath. "So I stated it. And then I was gently but firmly ushered back into the street again." "They didn't believe you," said Morgan. "Not for a minute. They laughed in my face." "Next I tried the police. I got the same treatment there, only they weren't so gentle. They wouldn't listen either. They muttered something about cranks and their crazy notions, and when they asked me where I lived, they thought I was—what did they call it?—a wise guy! Told me to get out and not come back with any more wild stories." "I see," said Morgan. Jefferson Parks finished his last bite of pie and pushed the plate away. "By then I didn't know quite what to do. I'd been prepared for almost anything excepting this. It was frightening. I tried to rationalize it, and then I quit trying. It wasn't that I attracted attention, or anything like that, quite the contrary. Nobody even looked at me, unless I said something to I could show them, and say, see, this proves that I'm telling "And what did you find?" The man gave a short laugh. "And your house dogs! obvious ones. I couldn't find any. You can see that, just looking at me. So I searched for more subtle things. Skin texture, fingerprints, bone structure, body proportion. I still couldn't find anything. Then I went to a doctor." Morgan's eyebrows lifted. "Good," he said. Parks shrugged tiredly. "Not really. He examined me. He practically took me apart. I carefully refrained from saying anything about who I was or where I came from just said I wanted a complete physical examination, and let him go to it. He was thorough, and when he finished he patted me on the back and said, 'Parks, you've got nothing to worry about. You're as fine, strapping a specimen of a healthy human being as I've ever seen.' And that was that." Parks laughed bitterly. "I guess I was supposed to be happy with the verdict, and instead I was ready to knock him down. It was idiotic, it defied reason, it was infuriating." Morgan nodded sourly. "Because you're not a human being," he said. Morgan asked curiously. "There must have been a million others to choose from." Parks unbuttoned his collar and rubbed his stubbled chin unhappily. "I didn't make the choice. Neither did anyone else. Travel by warp is a little different from travel by the rocket The warp is blind flying, strictly blind. We send an unmanned scanner ahead. It probes around more or less hit-or-miss until it locates something, somewhere, that looks habitable. When me. If it looks good to the scout, he signals back, and they from the other side. Then we can just scan a segment of good for the stars. When the warp principle was discovered, it "And you found things here the same as back home," said the same, with precisely the same anatomy and physiology, the the other side of the universe from mine, with the first intelligent they won't believe me !" "Why should they?" asked Morgan. "You look like a human being. You talk like one. You eat like one. You act like one. What you're asking them to believe is utterly incredible." " But it's true. " as I asked before, even if I did expect me to do about it? Why pick me , of all the people you've seen?" There was a desperate light in Parks' eyes. "I was tired, tired of being laughed at, tired of having people looking at me as though I'd lost my wits when I tried to tell them the truth. with another intelligent race! Combine our knowledges, ! That's what you can do. You can tell the know how public interest can be aroused in my world. It must "You mean nobody would believe you?" " And then Morgan was laughing, laughing bitterly, tears rolling down his cheeks. "And I'm the one man who couldn't "Why not?" "Because I'd be worse than no help at all." Jefferson Parks gripped the table, his knuckles white. "Why?" he cried hoarsely. "If you believe me, why can't you help me?" Morgan pointed to the magazine lying on the table. "I write, yes," he said sadly. "Ever read stories like this before?" Parks picked up the magazine, glanced at the bright cover. "I barely looked at it." "You should look more closely. I have a story in this issue. "Go ahead, look at it." The paragraph said: "Just suppose," said Martin, "that I did
