"Let us go back and fill up the diving bell," said Amos Fearless, by signs.

Dave was more than willing, and they soon had the diving bell as close as possible to the door of the mound.

They had brought several bags along, and into these they began heaping the gold.

It was hard work, but this they did not mind.

The finding of the treasure meant to them a lifetime of leisure, had they a mind to take it.

At last the bags were full and still more of the gold remained.

"We will pile it on the floor of the diving bell," signed Amos Fearless. "Let us make one trip of it. After this I never wish to visit the bottom of the sea again."

Both worked steadily, and in half an hour had every piece of gold in sight picked up.

They were just taking the last of the gold to the diving bell when a horrible roar broke upon their ears.

The demons of the deep were returning to the locality.
