"The volcano is surely alive!" cried the young man.

The crew, loafing on the forecastle, saw the phenomenon, and their chattering voices rose in a chorus of excitement. Tyke came up from below and joined Drew and the captain's daughter. The glare of the volcano illuminated the night, and they could see each other's features distinctly.

"Looks like we'd stirred things up over there," chuckled the old man. "There are more'n ghosts of dead and gone pirates guarding that treasure."

"It—it is rather terrifying, isn't it?" Ruth suggested.

"It is to them ignorant swabs for'ard," growled Tyke. "Good thing, though. They'll be too scared to want to roam over the island. We want it to ourselves till we find the loot. Don't we, Allen?"

"That's true. The disturbance over there may not be an unmitigated evil," was the young man's rejoinder.

Captain Hamilton called Ruth through the open window of his cabin, and she bade Grimshaw and Allen Drew good night and went below. Tyke remained only long enough to finish his cigar, then he departed.

The light over the volcano faded, the rumblings ceased. Drew, in his rubber-soled shoes, paced the deck alone; but he could not be seen ten feet away, for he wore dark clothes.

He knew that Mr. Rogers had long since gone to his room. Most of the crew had either sought their bunks or were stretched out on the forecastle hatch. Yet he heard a low murmur of voices from amidships. When he paced to that end of his walk, the voices reached him quite clearly and he recognized that of the one-eyed mate. The other man he knew to be Bingo, the only English sailor aboard—a shrewd and rat-faced little Cockney.

"Blime me, Bug-eye! but wot Hi sye Hi means. The devil 'imself's near where there's so much brimstone. If that hull bloomin' 'ill blows hup, where'll we be, Hi axes ye?"
