Big Hobart Zircon chuckled. "Don't worry, Rick. If you do, we'll go off with you. Would it make you happier if I carried the explosives?"

Rick considered. "It doesn't matter," he said. "If the stuff goes off, we'll all go into orbit at the same time and the jeep will go with us. Let's go."

Scotty looked at him curiously. "Where are the caps?"

Rick patted his pockets one at a time. "One in each breast pocket and one in my watch pocket. Don't push me around, buddy. I'm loaded."

Scotty grinned. "I'll keep my distance."

The rest of the party was loading jeeps now, too. Scotty hoisted the equipment and lunches into the back of the jeep and got in with them. Rick climbed gingerly into the front passenger seat and Zircon got ready to drive. He handed Rick a map. "You navigate. Our first destination is marked with a cross. We start out on the road leading west from the hotel. That will take us to the pumice works."

"Okay," Rick began, but he never finished. The jeep began to rock under him. For an insane instant he thought it must have a perfectly silent motor, then he realized Zircon had not yet turned on the ignition switch. Sudden dizziness made him clutch at the seat, and instinctively he clapped an arm across his chest to protect the dynamite caps.

He was vaguely conscious of yells from around him, and he struggled to sit up straight. His stomach was churning and he felt nauseated. Zircon let out a bellow like a wounded steer.

From inside the hotel Rick heard the sudden crash of shattering glass and gripped the jeep seat tighter with his free hand.

Then, as suddenly as it had come, it was over. He straightened up, dizzy. "Wh-what happened?" he asked shakily.
