They left the galley and proceeded on to the next section within the Carefree, leaving Gino singing another operatic air. The boys wondered if they could hold out until lunch time.

“Up ahead of us,” Captain Eaton said presently, after passing through a short hallway, “is the dormitory. Since the dorm is used solely for sleeping, we made it small so that we could give more area over to the other parts of the ship where we spend more of our time.”

Garry found the dormitory indeed small and quite simple. There were three-tiered bunks along the walls, with ladders leading up to the second and third levels.

The captain smiled. “Patch, you seem to be looking over those bunks carefully to see if you find any that aren’t made up.” Patch blushed. “Yes, Sir. I was wondering if....”

“If we have room for you two? Well, breathe easily, for we do have extras. The ship will sleep twelve, and special cots can be set up to accommodate more when necessary.”

“They look cozy,” Garry said, “but how do you know when to sleep out here in space, without any real night or day?”

“We observe a twenty-four-hour day just as they do on earth. Scientists have found out that space travelers get along much better if they keep the same hourly habits to which they are accustomed. We even simulate the appearance of night, turning down the lights and observing quiet. You’ll find out that you get sleepy at just the right time and that you wake the ‘next morning’ feeling just as refreshed as you did on earth.”

Suddenly, they heard a stirring in one of the top bunks. A deeply tanned man with a thick shock of auburn hair raised up sleepily.

“Oh, it’s you, Captain,” the man said with a yawn. Then he perked up. “Who is it with you, Sir?” The man’s accent was a thick Scottish brogue.

“We have guests, Mac,” the captain replied. “These are Garry and Patch. Fellows, meet Mr. McIntosh, pilot, navigator, engineer, and what have you. He likes to be called Mac.”
