"That girl has every ounce of brains that any woman can be trusted with!" Brent said warmly. "She thought of things that would never have occurred to me! As a psychologist, I could see how good her ideas were when she brought them up, but as a male I'd never have dreamed of them." Then he grinned. "She fell down on just one point. So did everybody else. Nobody happened to think of a garbage-disposal system for the Platform."
It came into Joe's mind that garbage-disposal was hardly a subject one would expect to be discussing in interplanetary space. But the Platform wasn't the same thing as a spaceship. A ship could jettison refuse and leave it behind, or store it during a voyage and dump it at either end. But the Space Platform would never land. It could roll on forever. And if it heaved out its refuse from airlocks—why—the stuff would still have the Platform's orbital speed and would follow it tirelessly around the Earth until the end of time.
"We dry and store it now," said Brent. "If we were going to live, we'd figure out some way to turn it to fertilizer for the hydroponic gardens. It's hardly worth while as things are. Even then, though, the problem of tin cans could be hopeless."
The Chief wiped his mouth deliberately. He had helped load four guided-missile launching tubes, and he had been brought up to date on the state of things in the Platform. He growled in a preliminary fashion and said, "Joe."
Joe looked at him.
"We brought up six two-ton guided missiles," said the Chief dourly. "We'll have warning of other bombs coming up. We can send these missiles out to intercept 'em. Six of 'em. They can get close enough to set off their proximity fuses, anyhow. But what are we going to do, Joe, if somebody flings seven bombs at us? We can manage six—maybe. But what'll we do with the one that's left over?"
"Have you any ideas?" asked Joe.
The Chief shook his head. Brent said mildly. "We've worked on that here in the Platform, I assure you. And as Sanford puts it quite soundly, about the only thing we can really do is throw our empty tin cans at them."
Joe nodded. Then he tensed. Brent had meant it as a rather mirthless joke. But Joe was astonished at what his own brain made of it. He thought it over. Then he said, "Why not? It ought to be a very good trick."
Brent stared at him incredulously. Haney looked solemnly at him. The Chief regarded Joe thoughtfully out of the corner of his eye. Then Mike shouted gleefully. The Chief blinked, and a moment later grunted wrathful unintelligible syllables of Mohawk, and then tried to pound Joe on the back and because of his want of weight went head over heels into the air between the six walls of the kitchen.
