A loud burst of laughter behind him suddenly brought Tom back to Earth. He smiled to himself and shook his head, as though reluctant to leave his dream world. He glanced out of the window again, this time down at the quadrangle, and far below he recognized the squat, muscular figure of Warrant Officer Mike McKenny drilling another group of newly arrived cadet candidates. Tom saw the slidewalks begin to fill with boys and men in varicolored uniforms, all released from duty as the day drew to a close. Tonight, Astro, Roger, and he would go to see the latest stereo, and tomorrow they would blast off in the Polaris for the weekly checkout of her equipment. He turned back to Spears, Coglin, and Duke. Roger was just finishing the story of their latest adventure (described in The Revolt on Venus).

"The best part, of course, was the actual hunting of the tyrannosaurus," said Astro.

"A tyrannosaurus?" exploded Spears, the youngest and most impressionable of the three Earthworms. "You actually hunted for a dinosaur?"

Astro grinned. "That's right. They're extinct here on Earth, but on Venus we catch 'em and make pets out of the baby ones."

"We could have saved ourselves a lot of trouble, though," commented Roger mockingly. "We have several officers here that would have served just as well. Major 'Blast-off' Connel, for instance, the toughest, meanest old son of a hot rocket you have ever seen!"

"Stand to!"

The six boys nearly broke their backs jumping to attention. A squat, muscular figure, wearing the black-and-gold uniform of a Solar Guard, strode heavily into their line of vision. Roger gulped as Major Connel stopped in front of him. "Still gassing, eh, Manning?" he roared.

"'Evening, Major, sir," mumbled Roger, his face beet red. "We—er—ah—were just telling this Earthworm unit about the Academy, sir. Some of its pitfalls."

"Some of the cadets are going to fall into a pit if they don't learn to keep their mouths shut!" snapped Connel. He glared at Tom, Astro, and Roger, then wheeled sharply to face the three quaking freshmen cadets. "You listen to anything they tell you and you'll wind up with a book full of demerits! What in blazes are you doing here, anyway? You're supposed to be at physical exams right this minute!"

The three boys began to shake visibly, not knowing whether to break ranks and run or wait until ordered.
