"That's right, Manning," said Strong. "You three will guide all visitors through the Polaris."
"How long will we be there, sir?" asked Tom.
"A month or so, I guess. The Polaris will be the first Academy exhibit. When you leave, another unit will replace you with their ship and do the same thing."
"But—but—" stammered Astro, "what will we say to them? The visitors, I mean?"
"Just answer all their questions, Astro. Also, make up a little speech about the functions of your particular station."
Strong looked at his watch and rose to his feet. "It's getting late. Check the Polaris over and stand by to raise ship in an hour."
"Yes, sir," said Tom.
The cadets came to attention, preparing to leave.
"One thing more! Don't get the idea that this is going to be a space lark," said Strong. "It's very important for the people of the Solar Alliance to know what kind of work we're doing here at the Academy. And you three have been selected as representatives of the entire Cadet Corps. So see that you conduct yourselves accordingly. All right, dismissed!"
The three cadets saluted sharply and filed out of the room, their skipper's final words ringing in their ears.
