"Very well, send them in," said Walters. Switching off the teleceiver, he turned back to Governor Hardy. "Ever hear of the Polaris unit, sir?" he asked.

Hardy paused, rubbing his chin before answering. "No, can't say that I have." He smiled. "From the look on your face, I see I should know about them, though."

Walters smiled back. "I'll just say this about them. Of all the cadet units trained here at the Academy in the last twenty years, these three lads are just about perfection. Just the material you'll need on your initial operation."

Governor Hardy raised his hand in mock protest. "Please! No brain trusts!"

"Well, they have the brains all right." Walters laughed. "But they have something else, an instinctive ability to do the right thing at the right time and that indefinable something that makes them true men of space, rather than ordinary ground hogs simply transplanted into space."

As the commander spoke, the massive door to his office rolled back and Tom, Roger, and Astro stepped in briskly, coming to stiff attention in front of the desk.

"Polaris unit reporting for duty, sir," said Tom. "Cadets Corbett, Manning, and Astro."

"At ease," said Walters.

The three boys relaxed and glanced quickly at the governor who had watched their entrance with interest. Walters came around in front of the desk and gestured toward Hardy.

"Boys, I want you to meet Governor Hardy."
