“Ideas? You mean for saving Homo sapiens? I’m afraid not. I simply do not feel up to saving six billion sentient organisms today. I feel—” “You’re getting hysterical,” said Banner, whose own tight, small voice was barely audible. “I got an opinion,” said Arnold. “You guys stop crying for a minute and I’ll tell you.” It took him five minutes to explain the whole thing. When he was through, both Banner and Harcraft turned him down flat. “Not a chance,” said Banner. It would take a week to set the thing up, and then it wouldn’t work. Our best chance is a long one, but maybe we’ll make it. We’re four weeks away from any fleet contact, but it’s the only sensible course of action.” “That makes it a total of eight weeks, with four weeks to get back here. That’s two months,” said Arnold. “You think they’re gonna wait two months before they shove out of here?” “Maybe not,” Banner said. “But that’s the only thing to do. And the sooner we get started the better the chances. Let’s get going.” “You look here—” Arnold began. “No more opinions, Bean Brain. You’re not entitled to an opinion. You think we should take your word for everything you told us? Tell me why. You said yourself you never had any training. So you’re guessing and hoping. It would take a staff of two dozen highly specialized technicians to even evaluate your idea, much less put it into action. Hell, man, face it. What do you know about geology, chemistry, mining? What do you know about anything?” Arnold pointed a trembling finger at Banner. “Look, I told you that I know rock. I know plenty of gardening, too. I gave you guys a chance to say O.K. You still say no? Have it your way, but we’ll do it my way.” Both Banner and Harcraft found themselves staring into the barrel of the ship’s only weapon. Harcraft recovered from his astonishment quicker than Banner. “O.K., Bean Brain, have it your way.” Quickly, casually he started for the cabin door. Then, with such speed that Banner hardly saw the movement, he chopped down viciously toward Arnold’s wrist with the edge of his hand. Harcraft recovered consciousness a half hour later. “Don’t try that again, little boy,” said Arnold with unconcealed hatred. “I’ll give you another thirty minutes to catch your breath. Then we all go to work.” It took ten days instead of seven. Under Arnold’s close supervision, they made the ship perform like a tractor, an air hammer, a foundation borer and an angledozer. Once, when they told him that some particular maneuver couldn’t be done, he took the controls himself, and came so close to killing them all that Banner, out of sheer terror, took over and made it do the things Arnold decreed necessary. Finally it was finished. Two million tons of potato fertilizer, one million tons of tractor fuel combined into a slimy pulp lay jammed into the largest crevice on the asteroid. A few hours later they were a thousand miles out in space. “Now?” asked Banner. “Now,” said Arnold.
