"Yeah," added Barney good naturedly, "do we find 'em in Joe's or elsewhere?"

"The Joe-Section of the engineering has been completed," said Arden with a grin. "They nearly drove Joe nuts for about a week."

"What were they doing?" asked Jim. "Building an electronically-operated Martini?"

"When I tell you, you won't believe me," said Arden. "But they've been living in Joe's refrigerator."

"Refrigerator?" gasped Christine.

"Just like a gang of unhung hams," said Arden. "But they're out now."

"Well! That's good."

Arden paused in front of three doors on the residence level near her apartment and Jim, Christine, and Barney each put their traveling bags inside. Then Arden led them high into the station where they came to a huge bulkhead in which was a heavy door.

Arden opened the door and an icy blast came out.

"Jeepers!" exploded Christine.
