They sat atop their vehicles, lean and aloof, dashing in, whirling, shooting across the field to their ship and back like wild horsemen on the plains one arm curled up over his head and around the hoist cable. He was in his dusty brown Marine uniform, the scarlet collar tabs bright as blood at were toughest, cruelest life-form in the Universe, unfit to mingle with the gentler wiser races in the stars, and a sure bet to steal their galaxy and corrupt it forever. Where except for those two. "They'll kill him. They'll kill him we tried Production Miracles, we tried patriotism, we tried damning the torpedoes and full speed captain of a destroyer. If I'd had a cruiser's range, I would have reached it." He looked at the Jek. "Where were you?" "I was here when you were." "I want to speak to your ship's captain." races in the stars. That way, we lived. That way, we were permitted to carry on our little concerns, and of the human race to the wiser, gentler their own affairs, and we knew they would leave us alone so long as we didn't bother them. cargo. The stoker came back to our ship that night, without his duffelbag. He found me and said: "I'm signing off the ship. Going screwball way they've got it set up." "Huh?" The stoker shrugged. "Ships are ships, and physics is physics, no matter where you go. I'll make out." "What kind of a deal did you and I, loading cargo aboard the Serenus . MacReidie was First Officer. I was Second. The stranger came while. It ought to be interesting," he said. "On a Jek ship." "Anybody's ship. When I get to Mac looked him over. He saw the their home world, I'll probably ship You wouldn't know. There's no such thing as a stoker any more, with automatic ships. But the stranger knew what Mac meant. Serenus had what they called an electronic drive. She had to run with an evacuated engine room. The leaking electricity would have broken any stray air down to ozone, which eats he could. "Nothing," I said, and that was had already left on the Jek ship, and it turned out he'd trained an apprentice boy to take his place. that, except MacReidie was always a better of the two interstellar freighters the human race had left.

It was the look you saw in the bars back on Earth, where the veterans of fall so they could go out into the alleys and have drunken fights among to people. Nobody could.

But he had brought that what path he wandered from people and I—almost all of the men in the Merchant Marine—hadn't One and two and three heads, tails, freighted supplies, and we had seen ships dying on the runs—we'd had our own brushes with commerce raiders, and we'd known enough men I didn't know what to say. MacReidie things so much better for us. I don't know if he did anything, but stoke their ships and, I suppose, fix them when they were in trouble. I wonder if he sang dirty songs in that bad been the same as ours. He'd commanded a fighting ship, somewhere, the war this man had fought hadn't and come to grips with things we simply didn't know about. The mark I'm a captain now, with master's papers, and you won't find "Thanks." The stranger walked me in my cabin very often ... there's looking out at the stars you're moving 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.

If he meant to. I wish —officers and crew. Even so, we had to sleep in shifts, with the ship's designers giving ninety per cent of her space to to know for sure that he was the first living being ever to travel all the way around the galaxy. his straps, and fell asleep.

"Captain leave any special instructions in the Order Book?" he asked. "Just the usual. Keep a tight watch wrong with him. He's got an old Marine uniform in his duffel." look to Mars, to the landing field, "You don't know," Mac said. "It's there. In his duffel. Damn it, we're going out to trade with his sworn enemies! Why do you suppose he wanted to sign on? Why do you suppose he's so eager to go!" "You think he's going to try to start something?" down—do you suppose they'll stop with him? They'll kill us, and then stomach. I didn't want any trouble. Not from the stoker, not from Mac. None of us wanted trouble—not even Mac, but he'd cause it to get rid of it, if you follow what I mean six legs—after all, ships are ships and they've all got to have something to push them along. If a man knows his business, why not? A man can Skipper says 'Cheer up, brave boys, we'll—' " " Twas the last cruise of the Venus, by God you should of seen us! The to make things risky, the jets were ... " The crew were chuckling into their own chest phones. I could hear Daniels trying to cut him off. But he No one's supposed to jam an intercom, but it made the crew feel good. When the crew feels good, the ship runs right, and it had been a long time since they'd been happy. He went on for another twenty way it should have been. It hadn't even missed a beat. He went down to sick bay, got the arm wrapped, and would have gone back on shift if Daniels'd let him. Those of us who were going off shift found him toying with the theremin in the mess compartment. He didn't know how to play it, and it sounded like a dog howling. "Sing, will you!" somebody yelled. He grinned and went back to the "Good Ship Venus ." It wasn't good, each other, and we all began drifting out of the mess compartment. And maybe it got to him, too. It may explain something. He and I middle of taking off his shirt. He stood there, looking out the porthole, and forgot I was there. I heard him reciting something, softly, under his man can be sure of another. He shook himself like a dog out of cold water, and got into his bunk. I don't know what MacReidie may have told the skipper about the stoker, or if he tried to tell him anything. The captain was the senior ticket holder in the Merchant Service, and a good man, in his day. He kept mostly to his cabin. And there was nothing MacReidie could do on his own authority—nothing simple, that ship, and ... I think what kept anything from happening between MacReidie and the stoker, or anyone else and the stoker, was that it would have meant trouble in the ship. Trouble, confined to our little percentage of the ship's volume, could seem like something one began anything, we could all get along. We could have a good trip. MacReidie worried, I'm sure. I worried, sometimes. But nothing as the other trips we'd made, and the same kind of landfall. The Lud factor came out of his post after we'd waited for a while, and gave us our
