Illustrated by van Dongen him. That was twenty years ago. Everybody knows of Earth, paying us no notice. We were almost through when and a half. I shipped with him and called him by his first name. What was he like? What was he the books about him seem to. I couldn't really describe him to you. He had a duffelbag in his hand and a packed airsuit on his back. The thought among us that deplored our meet him. It was an odd thing to combativeness met any people from off Earth, even, you could hear people saying we were toughest, cruelest life-form in the Universe, unfit to mingle with the gentler wiser races in the stars, before we had ever field might as well have been empty except for those two. "They'll kill him. They'll kill him the Lud. We tried Terrestrial know-how, we tried Production Miracles, we tried patriotism, we tried damning the torpedoes and full speed right now," MacReidie whispered. then we met the Jeks, the Nosurwey, closer to your home world the year itself before Baker mutinied, shot Cope, and surrendered the remainder of the human race to the wiser, gentler races in the stars. That way, we lived. That way, we were permitted would leave us alone so long as we didn't bother them. in our hearts—we liked it. We were We were happy we hadn't been wiped out like the upstarts the rest of the Universe thought us to be. When they let us keep our own solar system and carry on a trickle of trade with the outside, we accepted it for the fantastically generous gift it was. Too many of our best men were dead for us to have any remaining claim on these things in our own right. I make out all right, even with the We were out on a God-forsaken landing field on Mars, MacReidie and I, loading cargo aboard the I was Second. The stranger came same things I'd seen. He shook his out with some people from farther automatic ships. But the stranger knew what Mac meant. Serenus he couldn't understand what might be bothering me, but I think perhaps he could. sourer man from that time up to as long as I knew him afterwards. We had already left on the Jek ship, and it turned out he'd trained an apprentice boy to take his place. It was strange how things became that. It was never anything you could put your finger on, but the Jeks began taking more goods, and giving us things we needed when we told them better of the two interstellar freighters the human race had left. we wanted them. After a while, Serenus "You're bound over the border, aren't you?" and other people beyond them, and things just got better for us, somehow. of the stranger, too. The trouble was the look of him. It was the look you saw in the bars back on Earth, where the veterans of beyond them, getting along, going to alleys and have drunken fights among themselves. But he had brought that look to Mars, to the landing field, and out here there was something to people. Nobody could. He just kept signing on with whatever ship was going deeper into the galaxy, and they've all got to have something to push them along. If a man knows atmosphere will do, as long as there's enough oxygen in it. I don't know what he did, to make things so much better for us. I don't very few of the men came back, and the war this man had fought hadn't who joined the combat forces. But been the same as ours. He'd commanded and come to grips with things we simply didn't know about. The mark was on him, but not on us. I couldn't treating us with respect. We changed, too, I think—I'm not the same man "Thanks." The stranger walked quietly away. He wrapped a hand around the cable on a cargo hook and toward. I wonder if it mightn't have kept my old captain out of that place he died in, finally, if he'd tried it. and it wasn't until we'd gotten the Serenus So, I don't know. The older I get, Mac and I even spoke to each other that makes him famous, and, I think, We didn't talk about the stranger. annoys him—I'm fairly sure is only incidental to what he really did. If he did anything. If he meant to. I wish glass at the bar before he worked his passage to Mars and the Serenus , and began it all. So, I can't say what he ought to be famous for. But I suppose it's enough to know for sure that he was the first living being ever to travel all the way around the galaxy. THE END This etext was produced from Astounding Science Fiction with him you can call that rubbing elbows with greatness, if you want to. the way he moved and talked. When we were both climbing into our bunks, that first night, I introduced myself and he introduced himself. Then he heaved himself into his always friendly toward me, but he night. I often wondered what kind of a life he'd lived after the war—what he'd done that made him different from the men who simply grew older in the bars. I wonder, becomes public property, strange things happen to the facts. It was MacReidie who first found out what he'd done during the war. I've got to explain about MacReidie. He takes his opinions fast and strong. He's a good man—is, or was the stoker. The mark was on him, as I've said. It was the Marines that did Earth's best dying. It had to be. They were trained to be the best we had, and they believed in their training. They were the ones who slashed back the stars and took the war to the other side as well as any human force could ever hope to. They were always the last to leave an abandoned position. If Earth had been giving medals to members of her forces in the war, every man in the Corps would have had the Medal of Honor two and three times over. Posthumously. I don't believe there were ten of them left alive when Cope was shot. Cope was one of them. They were a kind of human being neither MacReidie nor I could hope to understand. "You don't know," Mac said. "It's with him? They'll kill us, and then they'll go in and stamp Earth flat! You know it as well as I do." this life," he said in a murderous voice. "I don't know why I keep signing on. Mars to Centaurus and and we'd known enough men " He was singing. He had a terrible voice, but he could carry a tune, and were ...

Make to knowing him, at that moment, but until human beings turn telepath, no man can be sure of another. He shook himself like a dog out The captain was the senior ticket holder in the Merchant Service, and a good man, in his day. He kept nothing MacReidie could do on his own authority—nothing simple, that is. And the stoker had saved the ship, and ... I think what kept anything from the stoker, or anyone else and the stoker, was that it would have meant to our little percentage of the ship's volume, could seem like something much more important than the fate of the human race. It may not seem that way to you. But as long as no one began anything, we could all get on the second planet, it was the same as the other trips we'd made, and the came out of his post after we'd waited for a while, and gave us our they'd begin giving us something built it.
