"We certainly are, Corbett," replied Connel. "In two hours another cadet is arriving from the Academy to replace Roger. His name's Alfie Higgins. Perhaps you know him."

Tom smiled. "Yes, sir, we know him," he replied. "Cadet Higgins is a friend of mine. He carries the nickname of 'The Brain.' Has the highest I.Q. in the Academy."

"Good. I'm glad you know him, because this is going to be a rough trip. We got off to a bad start, but it's all over now. So forget it. And before I go, I want you to know this. In my personal opinion, Manning had nothing to do with the crash. I think the whole trouble was caused on the ship. I have nothing to back up my opinion, except my feelings. But feelings can go a long way in making a man innocent until proved guilty. Unit dis-missed!"

Alfie Higgins listened attentively to the story of the crash and Roger's disappearance as Tom, and then Astro, described the situation in detail.

"It is a pity, of course, but Manning was always the impulsive type. Not very definite in his attitude and emotionally unstable," commented Alfie when the story was finished.

"Lay off that talk, you overstuffed brain!" growled Astro. "In this outfit, Roger is just away on vacation!"

"Yes—yes, of course!" said Alfie quickly. It wasn't wise to get off on the wrong foot in a new unit, especially when one was trying to fill the shoes of a cadet, who, Alfie had to admit, had everything. Alfie Higgins' mother didn't raise any stupid children, he said to himself. He was too happy being a member of the Polaris unit, the hottest crew at the Academy, to allow anything to interfere with his success.

"I've heard a great deal about hyperdrive," he said quickly, changing the subject. "I would appreciate it if you could describe the basis of this new feature in space travel so that I may have at least a surface familiarity with its operation and application."

Astro gulped and looked at Tom. "Might as well get used to that kind of chatter, Astro," said Tom, smiling. "Alfie can't talk any other way."

"Is there something wrong with the way I speak?" asked Alfie, wrinkling up his nose a little to see through the thick lenses of his glasses.
