d Mr. Damon went to Philadelphia, as Mr. Damon was
acquainted with Mr. Fenwick.

Tom carefully inspected the Whizzer which was the name of Mr. Fenwick's
airship, and, after some difficulties, succeeded in getting the electric
craft in shape to make a flight.

Tom, Mr. Damon and Mr. Fenwick started to make a trip to Cape May in the
Whizzer, but were caught in a terrific storm, and blown out to sea.
The wind became a hurricane, the airship was disabled, and wrecked in
mid-air. When it fell to earth it landed on one of the small West Indian
islands, but what was the terror of the three castaways to find that the
island was subject to earthquake shocks.

But the earth-tremors were not the only surprise in store for Tom and
his two friends, On the island they found five men and two ladies, who,
by strange chance, had been stranded there when the yacht Resolute,
owned by Mr. George Hosbrook, was wrecked in the same storm that
disabled the airship. Mr. Hosbrook, a millionaire, was taking a party of
friends to the West Indies.

When the castaways (among whom were Mr. and Mrs. Amos Nestor, parents
of Mary Nestor, a girl of whom Tom was very fond) found that there was
danger of the island being destroyed in an earthquake, they were in
despair. There seemed no way of being rescued, as the island was out of
the line of regular ship travel.

Tom, however, was resourceful. With the electrical apparatus from the
wrecked airship, he built a wireless plant, and sent messages for help,
broadcast over the ocean.

They were finally heard, and answered, by an operator on board the
steamer Camberanian, which came on under forced draught, and rescued
Tom and his friends. It was only just in time, for, no sooner had
they gotten aboard the steamer in lifeboats, than the whole island was
destroyed by an earthquake shock.

But Tom, the parents of Mary Nestor, Mr. Damon, Mr. Fenwick, and all the
others, got safely home. Among the survivors from the yacht Resolute
was a Mr. Barcoe Jenks, who now, most unexpectedly, had confronted Tom
through the glass window of the jewelry store. Mr. Jenks was a peculiar
man. Tom discovered this on Earthquake Island. Mr. Jenks carried with
him some stones which he said were diamonds. He asserted that he had
made them, but Tom did not know whether or not to believe this.

When it seemed that the castaways would not be saved Mr. Jenks offered
Tom a large sum in these same diamonds for some plan whereby he mi
