Great hills and ridges were raised, deep valleys created, and countless forms of fish and marine life lay dead upon the white sands.

Truly, it had been a terrible action of Nature’s forces. The Vestal Virgin had seemed to literally sink into the shifting sands which now were high over her.

Bell was wholly satisfied that the treasure could never be recovered.

“I give it up,” he declared. “Let us go back.”

They were soon aboard the Dart again. Frank took his bearings as well as he could. He was not exactly sure whether he was half way through the valley or not.

The spirits of all revived greatly.

The Dart once more shot forward on her way. A good outlook was kept for sunken vessels.
