For a long time the four boys lay and watched these things in silence. It was like a fairy story to see all these strange inhabitants of the tropic seas.

“Whew,” sighed Fred at length, “that’s a wonderful sight.”

“I should say so,” exclaimed John heartily. “This is a wonderful island too. I am almost glad we were stranded here.”

“I’d be too,” said George, “if I was only certain we were going to get off all right.”

“Guess what Fred and I found this morning,” said Grant.

“It wasn’t any more wonderful than what Pop and I saw,” retorted John.

“What did you see?” demanded Grant.

“A rock that’s shaped just like a shark.”

“Huh,” snorted Fred. “That’s not half as good as what we found.”

“Tell us what it was then,” said George.
