"And kill innocent people who don't know what they're doing?" asked Tom. "No—put it down, Astro!"
"All right, brains!" snapped Roger. "What have you got to suggest?"
"There's only one thing we can do!" said Tom. "Down on the side of the hill here I noticed a small cave. Two of us could squeeze inside."
"Why only two?" asked Astro.
"Somebody would have to cover the entrance from the outside with a boulder and then give himself up!"
Astro slapped Tom on the back. "That's a terrific idea. Come on. You two hide and I'll move the rock over."
"Wait a minute, you goof," said Roger. "Don't be in such a hurry to be a blasted hero!" He turned to Tom. "Just like that Venusian hick to be ready to sacrifice himself to get a Solar Medal!"
"Don't argue, Junior," snapped Astro. "I'm the only one strong enough to move one of those rocks. You two hide and I'll cover you."
"Now wait a minute, Astro," Tom protested. "I didn't mean ..."
"You should have," replied Astro. "And if you don't get moving now, you'll never make it!"
