He shrugged his shoulders and collected the papers. It was as much torture for him, as it was for any cadet, he thought, and turned to the door. “All right, Astro,” he said to himself, “in ten minutes it’ll be your turn and I’m going to make it tough!”
Back in the quarters of Unit 42-D, Tom and Astro still pored over the books and papers on the desk.
“Let’s try again, Astro,” sighed Tom as he hitched his chair closer to the desk. “You’ve got thirty tons of fuel—you want to find the compression ratio of the number-one firing-tube chamber—so what do you do?”
“Start up the auxiliary, burn a little of the stuff and judge what it’ll be,” the big cadet replied. “That’s the way I did it on the space freighters.”
“But you’re not on a space freighter now!” exclaimed Tom. “You’ve got to do things the way they want it done here at the Academy. By the book! These tables have been figured out by great minds to help you, and you just want to burn a little of the stuff and guess at what it’ll be!” Tom threw up his hands in disgust.
“Seems to me I heard of an old saying back in the teen centuries about leading a horse to water, but not being able to make him drink!” drawled Roger from the doorway. He strolled in and kicked at the crumpled sheets of paper that littered the floor, stark evidence of Tom’s efforts with Astro.
“All right, wise guy,” said Tom, “suppose you explain it to him!”
“No can do,” replied Roger. “I tried. I explained it to him twenty times this morning while you were taking your control-deck manual.” He tapped his head delicately with his forefinger. “Can’t get through—too thick!”
Astro turned to the window to hide the mist in his eyes.
“Lay off, Roger,” snapped Tom. He got up and walked over to the big cadet. “Come on, Astro, we haven’t got much time. You’re due in the examination hall in a few minutes.”
“It’s no good, Tom, I just can’t understand that stuff.” Astro turned and faced his unit-mates, his voice charged with sudden emotion. “Just fifteen minutes on the power deck of anything with rockets in her and I’ll run her from here to the next galaxy. I—I can’t explain it, but when I look at those motors, I can read ’em like you read an astrogation chart, Roger, or you the gauges on the control deck, Tom. But I just can’t get those ratios out of a book. I gotta put my hands on those motors—touch ’em—I mean really touch ’em—then I know what to do!”
As suddenly as he had started, he stopped and turned, leaving Tom and Roger staring at him, startled by this unusual outburst.
“Cadets—stand to!” roared a voice from the doorway.
The three cadets snapped to attention and faced the entrance.
“Take it easy, Earthworms!” said Tony Richards. A tall cadet with closely cut black hair and a lazy, smiling face stood in the doorway.
“Lay off, Richards,” said Tom. “We haven’t time for gags now. Astro’s going to take his power-deck manual in a few minutes and we’re cramming with him.”
“OK—OK—don’t blow your jets,” said Richards. “I just wanted to see if there were any bets on which unit would cop honors in the manuals this afternoon.”
“I suppose you think your Unit 77-K will finish on top?” drawled Roger.
“I’d like to bet all the galley demerits we have in 77-K against yours.”
“With Astro on our team?” complained Roger.
“What’s the matter with Astro?” asked Richards. “From what I hear, he’s hot stuff!” It wasn’t a compliment, but a sharp dig made with a sly smile. Astro balled his huge hands into fists.
“Astro,” said Roger, “is the type that can smell out trouble on any power deck. But today he came down with a cold. No, I’m afraid it’s no bet, Richards.”
“I’ll give you two to one,” Richards offered.
“Nothing doing,” replied Roger. “Not even at five to one. Not with Astro.”
Richards grinned, nodded and disappeared.
Roger turned to face the hard stare of Tom.
“That was the dirtiest sellout I’ve ever heard, Manning,” Tom growled.
“Sorry, Corbett,” said Roger. “I only bet on sure things.”
“That’s OK with me, Manning,” said Astro, “but I’m afraid you sold yourself a hot rocket, because I’m going to pass!”
“Who are you kidding?” Roger laughed and sprawled on his bunk.
Astro took a quick step forward, his fists clenched, his face a mask of burning anger, but Tom quickly jumped in front of him.
“You’ll be late for the exam, Astro!” he shouted. “Get going or it’ll count against your mark!”
“Huh. What’s a few points more or less when you’re going to fail anyway,” snorted Roger from the bunk.
Again, Astro started to lunge forward and Tom braced himself against the Venusian’s charge, but suddenly the burly cadet stopped. Disengaging Tom’s restraining arms, he spoke coldly to the sneering boy on the bed.
“I’m going to pass the exam, Manning. Get that? I’m going to pass and then come back and beat your head off!” Turning on his heel, he stalked out of the room.
Tom immediately wheeled to face Roger, fire in his eyes, and the arrogant cadet, sensing trouble, jumped to his feet to meet him.
“What’s the idea of giving Astro a hard time?” demanded Tom.
“Cool off, Corbett,” replied Roger warily. “You’re fusing your tubes you’re so hot.”
“You bet I’m hot! Hot enough to blast you—again!” Tom deliberately spat out the last word.
Roger flushed and brought his fists up quickly as though to charge in, then suddenly dropped
