“Don’t forget to look for the silver trophy,” said Jack quickly.

“Oh, I’ve already spoken to Barry about that,” answered the boy from the oil fields. “We’re going to make a systematic hunt. Of course, it isn’t going to be very easy to locate the exact spot where the vase went down.”

“It was opposite that clump of big pines,” declared Randy. “I noticed the pines just as I went overboard,” he added, with a sickly grin.

“I’ll remember that—it ought to help us in locating the spot,” said Phil, and then walked away to bid some of his other friends good-by.

“Now then, Andy and Randy, tell us where we’re going!” cried Fred, when the Rover boys and girls and Ruth were left for a moment to themselves.

“You’re going out West,” answered Andy dryly.

“Out West? Where?” came from Jack and Fred.

“You’re going out to the Rolling Thunder gold mine,” said Randy.

“Rolling Thunder! What a name!” exclaimed Ruth, dimpling.
