TOM SWIFT AND HIS SUBMARINE BOAT




Chapter One

News of a Treasure Wreck


There was a rushing, whizzing, throbbing noise in the air.  A great
body, like that of some immense bird, sailed along, casting a grotesque
shadow on the ground below.  An elderly man, who was seated on the
porch of a large house, started to his feet in alarm.

"Gracious goodness! What was that, Mrs. Baggert?" he called to a
motherly-looking woman who stood in the doorway.  "What happened?"

"Nothing much, Mr. Swift," was the calm reply "I think that was Tom and
Mr. Sharp in their airship, that's all. I didn't see it, but the noise
sounded like that of the Red Cloud."

"Of course! To be sure!" exclaimed Mr. Barton Swift, the well-known
inventor, as he started down the path in order to get a good view of
the air, unobstructed by the trees. "Yes, there they are," he added.
"That's the airship, but I didn't expect them back so soon. They must
have made good time from Shopton. I wonder if anything can be the
matter that they hurried so?"

He gazed aloft toward where a queerly-shaped machine was circling about
nearly five hundred feet in the air, for the craft, after swooping down
close to the house, had ascended and was now hovering just above the
line of breakers that marked the New Jersey seacoast, where Mr. Swift
had taken up a temporary residence.

"Don't begin worrying, Mr. Swift," advised Mrs. Baggert, the
housekeeper. "You've got too much to do, if you get that new boat done,
to worry."

"That's so. I must not worry. But I wish Tom and Mr. Sharp would land,
for I want to talk to them."

As if the occupants of the airship had heard the words of the aged
inventor, they headed their craft toward earth. The combined aeroplane
and dirigible balloon, a most wonderful traveler of the air, swung
around, and then, with the deflection rudders slanted downward, came on
with a rush.  When near the landing place, just at the side of the
house, the motor was stopped, and the gas, with a hissing noise, rushed
into the red aluminum container. This immediately made the ship more
buoyant and it landed almost as gently as a feather.

No sooner had the wheels which formed the lower part of the craft
touched the ground than there leaped from the cabin of the Red Cloud a
young man.

"Well, dad!" he exclaimed. "Here we are again, safe and sound. Made a
record, too. Touched ninety miles an hour at times--didn't we, Mr.
Sharp?"

"That's what," agreed a tall, thin, dark-complexioned man, who followed
Tom Swift more leisurely in his exit from the cabin. Mr. Sharp, a
veteran aeronaut, stopped to fasten guy ropes from the airship to
strong stakes driven into the ground.

"And we'd have done better, only we struck a hard wind against us about
two miles up in the air, which delayed us," went on Tom. "Did you hear
us coming, dad?"

"Yes, and it startled him," put in Mrs. Baggert. "I guess he wasn't
expecting you."

"Oh, well, I shouldn't have been so alarmed, only I was thinking deeply
about a certain change I am going to make in the submarine, Tom. I was
day-dreaming, I think, when your ship whizzed through the air. But tell
me, did you find everything all right at Shopton? No signs of any of
those scoundrels of the Happy Harry gang having been around?" and Mr.
Swift looked anxiously at his son.

"Not a sign, dad," replied Tom quickly. "Everything was all right. We
brought the things you wanted. They're in
