"Yes," Scotty agreed. "Take a look around while I keep a watch. I have a funny feeling we're not alone here."

There was a fairly deep crater in the middle of the area. Rick stepped into it and kicked yellow earth out of his way. He was puzzled. There was nothing visible in the area except the yellow ground, and there was nothing about that to give him a clue to Connel's determination to keep them away.

His foot dislodged a clump of earth. It rolled to the bottom of the shot crater, exposing two large crystals. Rick picked them up and rubbed the dirt off. They felt rather greasy. He didn't think they were quartz. His mind ranged over the possibilities. Probably datolite, he decided. The color was about right, and he knew datolite was found in igneous rocks of volcanic origin. He put the crystals in his pocket.

A trace of blue caught his eye and he knelt, digging with his hands. He uncovered a few more of the datolite crystals and put them in his pocket. They weren't particularly good specimens; he had some in his rock collection that were perfectly formed and clear, but at least they were something to take home.

Digging uncovered a layer of hard blue rock, heavily pockmarked and filled with the yellow ground. He saw one place where the blue actually blended in with yellow and decided that the blue and yellow were probably the same rock. The slaty blue simply turned to yellow when it was exposed to the air for a while.

There were loose pieces of blue, broken by the dynamite blasts. He picked up a couple of smaller pieces, then added a piece of yellow to his collection. He uncovered another crystal, too, a large one nearly the size of a golf ball and put that in his pocket.

Scotty was getting restless. "Let's get going," he said. "I don't like this."

Rick had seen enough, and it had told him nothing. He was just as puzzled over Connel's motive as ever. Obviously, the answer was not here—or, if it was, they couldn't see it.

"Okay," he said. "Move out."

Scotty led the way back to the jeep. Rick got into the driver's seat and started the motor. He backed and turned in the narrow space Connel's jeep had created, and finally got his wheels straight for the run back.
