"What did you hear?" asked the young diver.

"I fancied I heard that gorilla again."

"Oh, don't say that!"

"Perhaps I was mistaken. But it would be just like the beast to follow us," continued the master of the Swallow.

"We will have to be on our guard."

Both looked around with care, but could see nothing of the gorilla. Then they pushed on once more, up the rocks and through a tangle of vines until they reached a bit of a clearing on the very top of the hill.

"Here we are, safe and sound!" said the captain. "I wish we had a spyglass."

They took a careful look around, and noted that the island was circular in form, with a small cove on the south shore, where the rowboat had landed.

On all sides stretched the rolling Pacific, the waves glistening brightly in the strong sunshine.

Not another island of any sort was in sight.
