Down it went until the glare of the electric lights revealed a rare and wonderful scene.

There were marine plants of queer and beautiful sort, cliffs, crags and reefs of vari-colored coral, thousands of fish of all hues and shapes, and many other strange and marvelous things.

The voyagers were for a time enchained by this wonderful exhibition.

Particularly was Stanhope enchanted, and he was anxious to possess some of the wonderful specimens that he saw.

“How can I get some of that lovely coral, Frank?” he cried. “It is a species I never saw before.”

“There is only one way,” said Frank.

“And how is that?”

“Simply put on a diving suit and go out there and get them.”

“Can I do that?”

Before Frank could answer a startling and terrible thing happened. A cry of terror came from Barney.
