AND THE STARS BY JOHN A. SENTRY drive. It's been a while since from all the others, somehow. It gave a new face to the entire planet. Mac and I and some of the other crewmen went down on the field to him? Yes, I know him— machinery from their own ship. 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 of Earth, paying us no notice. We were almost through when glass at the bar before he worked his the books about him seem to. I couldn't really describe him to where you go. I'll make out." and a packed airsuit on his back. The skin of his face had been dried out by ship's air, burned by ultraviolet "What kind of a deal did you did he look like? He looked like a man. It was after the war, and we were combativeness before we had ever 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, and a sure bet to steal their galaxy and corrupt it forever. Where these people got their information, I see—the stoker, and the Jek, who We were beaten. We moved out beyond Centaurus, and Sirius, and then we met the Jeks, the Nosurwey, the Lud. We tried Terrestrial know-how, we tried Production Miracles, a Jek, I would have thought that uniform was a death warrant. But the Jek spoke to him: "Are you entitled to wear that?" "I was at this planet in '39. I was closer to your home world the year before that," the stoker said. "I was captain of a destroyer. If I'd had a 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 "I want to speak to your ship's captain." "I was here when you were." to carry on our little concerns, and mind our manners. The Jeks and the cargo. 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 loudly: "What do you mean, you're going with the Jeks?" "I signed on their ship," the stoker said. "Stoking. They've got a micro-nuclear MacReidie was with me. He said "Huh?" years ago. I was a little, pudgy man with short breath and a high-pitched voice. I was a typical Earthman. We were out on a God-forsaken landing field on Mars, MacReidie and I, loading cargo aboard the Serenus make with them? What do you think you're up to?" The stoker shrugged. "Ships are ships, and physics is physics, no matter said. "On a Jek ship." "Anybody's ship. When I get to their home world, I'll probably ship out with some people from farther on. Why not? It's honest work." automatic ships. But the stranger knew what Mac meant. Serenus had what they called an electronic drive. She had to run with Serenus was an ugly old tub. At that, we were the better of the two interstellar freighters Serenus the human race had left. "You're bound over the border, aren't you?" MacReidie nodded. "That's right. But—" the Lud, too. Then it was the Nosurwey, and other people beyond them, It was the look you saw in the bars back on Earth, where the veterans of the war sat and stared down into their glasses, waiting for night 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 disquieting about it. with green shipmates and blue ones. One and two and three heads, tails, six legs—after all, ships are ships and they've all got to have something to people. Nobody could. He just kept signing on with whatever ship was going deeper into the galaxy, to get used to it. And any nontoxic atmosphere will do, as long as there's enough oxygen in it. I don't know what he did, to make live on all kinds of food, if he wants a fighting ship, somewhere, and come to grips with things we I was ... I think—not altogether the same I'm a captain now, with the loading. I was busy with mine, and it wasn't until we'd gotten the Serenus a bunch on the Serenus Serenus —officers and , and began it all. passage to Mars and the to know for sure that he was the first living being ever to travel all the way around the galaxy.

They were trained to be the best we had, and side as well as any human force could ever hope to. They were always the 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 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?" "Think! That's exactly what he's going farther and farther. He messed down—do you suppose they'll stop with him? They'll kill us, and then they'll go in and stamp Earth flat! You know it as well as I do." except for those two. "Easy! Easy—nothing's easy.

Trouble, confined 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 worried, sometimes. But nothing happened. When we reached Alpha Centaurus, and set down at the trading field on the second planet, it was the same as the other trips we'd made, and the for the first time that the Lud hadn't built it. It was a leftover from the old colonial human government. And the city on the horizon—men had built it
