Now was the captain's chance to prove he knew There was nothing showing on the video screen. That was why we were looking at it so analytically. "Transphasia, that's what it is," Ordinary Spaceman Quade stated with a definite thrust of his angular jaw in my direction. "You can take my word on that, Captain Gavin." "Stand your ground," I warned the others thickly. "They may be dangerous." . That's why I'm Captain." "You'll get over feeling like that." "I know. Then I'll become First Officer." Quade sat up on our crisscross litter of arms. "Aliens can't be "But look at that screen, sir," Quade said with an emphatic swing of hostile. Ethnic impossibility. I'll show you." Quade was delirious and we were drunk. He got away from us and jogged anything his scarred arm. "I've seen blank scanning like that before and you "Sssh, men," Nagurski said. "Leave it to me. I'll surround him." The men followed the First Officer's example, and the rope tying them "You are plain wrong, Captain. Traditionally, alien races never interfere with our explorations. Generally, they are so alien to us they can't even recognize our existence." It was true. The aliens formed a ring around us, and each time a bouncing boy hit the line, he only bounced back on top of us. everything else, even your own life." "Just a minute, Captain. I've never been 'busted.' In the Exploration Service, we regard Ordinary Spaceman as our highest rank. With my hazard pay, I get more hard cash than you to know what to expect, so maybe we can't maintain the reactionary caution the service likes in officers." "I resent the word 'reactionary,' Spaceman! In civilian life, I was "Captain Gavin," Quade said patiently, "you must realize that an outsider like you, among a crew of skilled spacemen, can never be more than a figurehead." Was this the way I was to be treated? Why, this man had deliberately insulted me, his captain. I controlled myself, remembering the familiarity that had always existed between members of a crew working under close conditions, from the time of the ancient submarines and the first orbital ships. Using the translator, we can learn to recognize all confused data as easily. I'm starting indoctrination courses." "I doubt that that is necessary, sir," Quade said. "Experienced cover exploring with rookies. With all due respect, Captain." is less painful and more efficient." "Can't," I told him. "I can't trust your opinion. I can't trust Quade squirmed. "Yes, sir. One thing, sir—I don't understand how you got me away from those aliens." I clapped him on the shoulder. "But, man, you have just been telling me all we had to worry about was common transphasia. A man with your The landscape beyond the black corona left by our landing rockets was unimpressive. The rocky desert was made up of silicon and iron oxide, were trying to find out things about their world, so they even offered us one of their own kind to study. Unfortunately, he was too much for us. They didn't give us their top man, of course, only the village idiot. It's just as well. We aren't allowed to dissect creatures that far up the intelligence scale." Earthmen to colonize the planet. We came here, you see, same as the dog came to Nagurski." "Well, I've learned one thing from all of this," Quade said. "I've been more. Isn't confidence a spaceman's most valuable asset?" "The hell it is," Quade said grimly. "It's his deadliest liability." "In that case, I must inform you that I am demoting you to Acting Executive Officer." "Huh?" Quade gawked. "But dammit, Captain, you can't do that to me! I'll lose hazard pay and be that much further from retirement!" Captain?" "Wait a minute, Spaceman!" I bellowed. "Where the devil do you think you're dragging me? Halt! That's a direct order." to get used to it." He said nothing on the route back to the spacer. "I know all about this sort of thing, Gav," First Officer Nagurski said expansively. He was rubbing the well-worn ears of our beagle mascot, Bruce. A heavy tail thudded on the steel deck from time to time. I was hot and tired, fresh—in only the chronological sense—from a pressure suit. "What do you know all about, Nagurski? Dogs? Spacemen? Women? Transphasia?" will soon see why the service selected you as captain "Did your crew voluntarily elect you as their leader?" "Of course they did, Gav. I'm an old hand at controlling crews." "Then why are you First Officer under me now?" He blinked, then decided to laugh. "I've been in space a good many years. I really wanted to relax a little bit more. Besides, the increase in hazard pay was actually more than my salary as a captain. a thing, Nagurski. Your trust of these damn-fool spacemen is why you are no longer a captain. You can't trust anything out here in space, much less human nature. Even I know that much!" think of me—of us , the officers, as their leaders. As far as the crew is concerned, Ordinary Spaceman Quade is the best man on this ship." sites that often. You can't use the drive in a gravitational field, you know." "What else can we do, Captain?" Nagurski asked puzzledly. "Nagurski, if you are looking for a job safer than space exploration, why don't you go back to testing cosmic bomb shelters?" Nagurski flushed. "Look here, Captain, you are being too damned cautious. There is a way one handles the survey of a planet like this, and this isn't the way." gambling so much of the ship. A captain doesn't take chances like that!" would be doing it wrong." "You know nothing about space, Captain! You have to trust us ." "That's it exactly, First Officer Nagurski," I said sociably. "If you lazy, lax, complacent slobs want to do something in a particular way, I know it I turned and found Wallace, the personnel man, standing in the hatchway. "Pardon, Captain, but would you say we also lacked initiative?" "I would," I answered levelly. "Then you'll be interested to hear that Spaceman Quade took a suit and a cartographer unit. He's out there somewhere, alone." "The idiot!" I yelped. "Everyone needs a partner out there. Send out a team to follow his cable and drag him in here by it." intended to go beyond the three-mile limit as you demanded." "Shut up, Wallace. You don't have to like me, but you can't twist what I said as long as I command this spacer." "Cool off, Gav," Nagurski advised me. "It's been done before. Anybody else would have been a fool to go out alone, but Quade is the most No one but a reckless fool would have gone out alone on a strange that space exploration made a man a reckless fool by doing things on one planet he had once found safe and wise on some other world. The thought intruded itself: why How could we be less vulnerable, or preferably invulnerable? "Captain, you got nothing to worry about," Quartermaster Farley said. He patted a space helmet paternally. "You got yourself a self-contained environment. The suit's eye looks into yours at the arteries in the "Yes, sir. That's what we all thought." A moment later, Nagurski added, "Anyway, I just noticed it was my "You," I said carefully, "have been in space a long
