those speedy machines, after Mr. Wakefield Damon had come to grief
on it. Mr. Damon was an eccentric man, who was always blessing
himself, some part of his anatomy, or some of his possessions.

After many adventures on his motor-cycle, Tom Swift went through
some surprising happenings with a motor-boat be bought. After that
he built an airship, the RED CLOUD, and later he and his father
constructed a submarine, in which they went under the ocean in
search of sunken treasure, enduring many perils and much danger.

Tom Swift's electric runabout, which he built after returning home
from the submarine trip, proved to be the speediest car on the road.
The experience he acquired in making this machine stood him in good
stead, when (as told in the sixth volume, "Tom Swift and His
Wireless Message") the airship in which he, Mr. Damon and a friend
of the latter's (who had built the craft) were wrecked on Earthquake
Island. There Tom was marooned with some refugees from a wrecked
steam yacht, among whom were Mr. and Mrs. Nestor, father of a girl
of whom Tom thought a great deal.

With parts from the wrecked electric airship the youth rigged up a
plant, and sent wireless messages from the island. The castaways
nearly lost their lives in the earthquake shocks, but a steamer,
summoned by Tom's wireless call, arrived in time to save them, just
as the island disappeared beneath the sea.

In the seventh book of the series, entitled "Tom Swift Among the
Diamond Makers" there was related the adventures of himself and his
friends when they tried to solve the mystery of Phantom Mountain.
