In a few moments the guard was back. He handed them laminated plastic badges with their names and pictures. At the bottom of Rick's were the numbers one, two, and three. Scotty's badge had only the numbers two and three.

"What do these mean?" Rick asked.

"Those are the areas where you're allowed to go. Area One is the blockhouse. Area Two is the main base and firing pads. Area Three is the machine shop and maintenance depot. You can go anywhere. Scott can go anywhere but inside the blockhouse. Sign these, please." He handed them forms in which they agreed to be bound by all security regulations, under penalty of the Espionage Act. They signed, and returned the forms.

"Go through the gate," the guard directed, "and report to the reception desk in Building Five. That's personnel. They'll take it from there."

They returned to the jeep and drove to the gate. The guard inspected their badges, compared the pictures with their faces, then waved them on.

"Taking no chances," Rick remarked. "There's Building Five."

The personnel office gave them another map, showing installations and buildings on the base itself, and assigned them to bunks nine and ten in Barracks Seven. Rick was told to report at eight in the morning to Dr. Gould in Building Twelve, while Scotty was told to report to Mr. Rhodes in Maintenance Building Twenty-three. They received a leaflet marked: "Read This."

They followed the map for another three miles, leaving the gate buildings out of sight behind a ridge of rock. Their map showed that the main cluster of buildings was three miles from the gate and nine miles from the blockhouse and the firing pads on the dry lake bed. Again, Rick began to appreciate Western distances.

The boys found their barracks without difficulty, and moved into a room containing four bunks. It wasn't elaborate, but it was adequate for a camp of this kind. It was clear that the other bunks were occupied, but at the moment their bunkmates were apparently out.

Rick stowed his gear in the locker with his bed number on it, then sat down to read the leaflet. It was a directory of camp facilities, plus a written lecture on security. He was allowed to say what kind of work he did, and that was about all.
