d, and there
was no more danger from that source.

True, the whole island was rumbling and trembling in the throes of
an earthquake, but, by this time, the refugees had become somewhat
used to this, and only the two ladies exhibited any outward signs of
great alarm, though Mr. Barcoe Jenks, Tom observed, was nervously
fingering the belt which he wore about his waist.

"I guess the worst is over," spoke Mr. Fenwick, as they stood
looking toward where part of the island had vanished. "The shock
expended itself on tearing that mass of rock and earth away."

"Let us hope so," added Mr. Hosbrook, solemnly. "Oh, if we could
only get away from this terrible place! We must hoist a signal of
distress, even if we are out of the track of regular vessels. Some
ship, blown out of her course may see it. Captain Mentor, I wish you
and Mr. Fordam would attend to that."

"I will, sir," answered the commander of the ill-fated RESOLUTE.
"The signal shall be hoisted at once. Come on, Mr. Fordam," he
added, turning to the first mate.

"If you don't mind," interrupted Tom, "I wish you would first help
me to get what remains of the airship up out of reach of any more
possible high waves. That one nearly covered it, and if there are
other big rollers, the wreck may be washed out to sea."

"I can't see that any great harm would result from that," put in Mr.
Jenks. "There isn't anything about the wreck that we could use to
make a boat or raft from." Indeed, there was little left of the
airship, save the mass of machinery.

"Well, it may come in handy before we leave here," said Tom, and
there was a quiet determined air about him, that caused Mr. Damon to
look at him curiously. The odd gentleman started to utter one of his
numerous blessings, and to ask Tom a question, but he thought better
of it. By this time the earthquake had ceased, and the castaways
were calmer.

Tom started toward the airship wreck, and began pulling off some
broken boards to get at the electrical machinery.

"I guess you had better give Mr. Swift a hand, Captain Mentor,"
spoke the millionaire yacht owner. "I don't know what good the wreck
can be, but we owe considerable to Mr. Swift and his friends, and
the least we can do is to aid them in anything they ask. So,
Captain, if you don't mind, you and the mate bear a hand. In fact,
we'll all help, and move the wreck so far up that there will be no
danger, even from tidal waves."

Tom looked pleased at this order
