Tom’s excited announcement startled
Mr. Damon and the others as much as if the young inventor
had informed them that the airship had exploded and
was about to dash with them to the earth. The
men leaped to their feet, and stared at the lad.
“A stowaway on board!”
cried Mr. Damon. “Bless my soul! How
did he—”
“Are you sure that message is
straight?” asked Mr. Jenks. “Did
Eradicate see the man?”
“He says he did,” answered
Tom. “The man is hidden away on board now—probably
among the stores and supplies.”
“Bless my tomato sauce!”
exploded Mr. Damon. “I hope he doesn’t
eat them all up!”
“We must get him out at once!” declared
Mr. Jenks.
“I knew something would happen
on this voyage,” came from Mr. Parker.
“I predicted it from the first!”
Tom thought considerable, but he did
not answer the scientist just then. Another communication
was coming to him by wireless. He listened intently.
“Father says,” the lad
told his companions “that Eradicate only had
a glimpse of the man at the last moment. He was
looking from the rear storeroom window—he’s
the same man who called on me that time—Rad
remembers him very well.”
“Bless my shoes! What’s
to be done?” inquired Mr. Damon, looking around
helplessly.
“We must get him out, that’s
all,” decided Mr. Jenks; with vigor. “Get
him out and drop him overboard!”
“Drop him overboard!” cried Mr. Parker,
in horror.
“Not exactly, but get rid of
him,” proceeded the diamond seeker. “That
man is one of my enemies. He has been sent by
the band of diamond makers hidden among the mountains,
to spy on me, and, if possible, prevent me from seeking
to discover their secret. He tried to work on
Tom’s Swift’s fears, and frighten him
from using his airship on this quest. Then, when
he failed, the man must have sneaked into the shed,
and hidden himself in the ship. We must get rid
of him, or he may wreck the Red Cloud!”
“That’s so!” cried
Tom. “We must try to capture him. I
think we had better—” the lad paused,
and again listened to the wireless message. “Father
says Eradicate saw the man have a gun, so we must
be careful,” the young inventor translated the
dots and dashes.
“Bless my powder horn!” exploded Mr. Damon.
“We shall have to proceed cautiously
then,” spoke Mr. Jenks. “If he is
like any others in the gang he is a desperate man.”
“Better sneak up on him then,
if we can,” proposed Mr. Parker. “There
are enough of us to cope with one man, even if he is
armed. You have weapons aboard, haven’t
you?” he inquired of Tom.
“Yes,” was the hesitating
answer, “but I don’t want to use them
if I can help it. Not only because of the danger,
and a dislike of shedding blood, but because a stray
bullet might pierce the gas bag and damage the ship.”
“That’s so,” agreed
Mr. Jenks. “Well, I guess if we go at it
the right way we can capture him without any shooting.
But we must talk more quietly—we ought
to have whispered—he may have heard us.”
“I don’t think so,”
replied Tom. “The storeroom is far enough
off so that he couldn’t hear us. Besides,
the motor makes such a racket that he couldn’t
distinguish what we were talking about, even if he
heard our voices. So, unless he heard the wireless
working, and suspects something from that, he probably
doesn’t know that we are aware of his presence
aboard.”
“But why do you think he has
remained quiet all this while, Tom?” asked Mr.
Damon.
“Probably he wants to wait until
the ship is farther out west,” suggested Mr.
Jenks. “Then he will be nearer his friends,
and can get help, if he needs it.”
“And do you really believe he
would destroy the Red Cloud?” asked Mr. Parker.
“I think that all he is waiting
for is a favorable chance,” declared the diamond
seeker. “He would destroy the craft, and
us too, if he could prevent us from discovering the
secret of Phantom Mountain, I believe.”
“Then we must get ahead of him,”
decided Tom, quietly. “I have just flashed
to dad a message, telling him that we will heed his
warning. Now to capture the stowaway!”
“And while we’re about
it, give him a good scare when we do get him,”
suggested Mr. Jenks.
“How?” asked Tom.
“Threaten to drop him overboard.
Perhaps that will make him tell how he happened to
get in our ship, and what are the plans of the gang
of diamond makers. We may get valuable information
that way.”
“I don’t believe you can
scare such fellows much,” was Tom’s opinion,
but it was agreed to try.
“How are you going to capture
him?” asked Mr. Parker. “If he has
a gun it won’t be any too easy to go in the storeroom,
and drag him out.”
“We’ll have to use a little
strategy,” decided Tom, and then they discussed
several plans. The one finally adopted was that
Tom and Mr. Damon should enter the storeroom, casually,
as if in search of food to cook for supper. They
would discuss various dishes, and Mr. Damon was to
express a preference for something in the food line,
the box containing which, was well hack in the room.
This would give the two a chance to penetrate to the
far end of the apartment, without arousing the suspicions
of the hidden man, who, doubtless, would be listening
to the conversation.
“And as soon as we get sight
of him, you and I will jump right at him, Mr. Damon,”
said Tom. “Jump before he has a chance to
use his gun. Mr. Jenks and Mr. Parker will be
waiting outside the room, to catch him if he gets
away from us. I’ll have some ropes ready,
and we’ll tie him up, and—well, we’ll
decide later what to do with him.”
“All right. I’m ready
as soon as you are, Tom,” said the eccentric
man. “Come ahead.”
They went softly to the storeroom,
and listened at the door. There was no sound
heard save that made by the machinery.
“I wonder if he’s really here?”
whispered Mr. Damon.
“We’ll soon find out,” answered
Tom. “Let’s go in.”
They entered, and, in pursuance of
their plan, Tom and his friend talked of various foods.
“I think I’d like some
of that canned lobster, with French dressing on,”
spoke the eccentric man.
“That’s away in the back
end of the room,” said Tom, in a loud voice.
“It’s under a lot of boxes.”
“Then I’ll help you get
it out! Bless my frying pan! but I am very fond
of lobster!” exclaimed Mr. Damon, in as natural
tones as was possible under the circumstances.
He and Tom moved cautiously back among
the boxes and barrels. They were glancing about
with eager eyes. Tom switched on an electric
light, and, the instant he did so, he was aware of
a movement in a little space formed by one box which
was placed on top, of two others. The lad saw
a dark figure moving, as if to get farther out of
sight.
“I’ve got him!”
cried Tom, making a dive for the shadow.
A moment later the young inventor
was bowled over, as a dark figure leaped over his
head.
“Catch him, Mr. Damon!” he cried.
“Bless my hatband! I—I—”
Mr. Damon’s voice ended in a grunt. He,
too, had been knocked down by the fleeing man.
“Look out, Mr. Jenks!”
cried Tom, to warn those on guard at the door of the
storeroom.
There was the report of a gun, some
excited shouts, and when Tom could scramble to his
feet, and rush out, he beheld Mr. Parker calmly sitting
on a struggling man, while Mr. Jenks held a gun, that
was still smoking.
“We caught him!” cried the scientist.
“Anybody hurt?” asked Tom, anxiously.
“No, I knocked up his gun as
he fired,” explained Mr. Jenks. “Where
are the ropes, Tom?”
The cords were produced and the man,
who had now ceased to struggle, was tightly bound.
He uttered not a word, but he smiled grimly when Mr.
Damon remarked:
“I guess I’ll go back
in the storeroom, Tom, and see how much food he ate.”
“Oh, I guess he didn’t
take much,” declared the lad. “He
wasn’t there long enough.”
“Well, Farley Munson, so it’s
you, is it?” asked Mr. Jenks, as he surveyed
the prisoner.
“Do you know him?” asked Tom, in some
surprise.
“He was in with the diamond
makers,” said Mr. Jenks. “He was
one of those who took me to the secret cave. But
it will be the last time he ever goes there.
How high up are we, Tom?”
“About two miles. Why?”
“I guess that will be far enough
to let him fall,” went on the diamond seeker.
“Come on, Mr. Damon, help me throw him overboard!”
“You—you’re
not going to throw me over—with the airship
two miles high; are you?” gasped the man.
“Will you tell us what we want
to know, if we don’t?” asked Mr. Jenks.
“What do you want to know?”
“How you got aboard, and what your object was
in coming.”
“That’s easy enough.
I had been hanging around the shed for several days,
watching a chance to get in. Finally I saw it,
when that colored man went to feed his mule, and I
slipped in, and hid in the airship. The stores
were all in then, and I stowed myself away among the
boxes. I had food and water, so I didn’t
touch any of yours,” and he looked at Mr. Damon,
who seemed much relieved.
“And what was your object?” demanded Mr.
Jenks.
“I wanted to prevent you from going to Phantom
Mountain.”
“How?”
“By destroying the airship if
need be. But I hoped to accomplish it by other
means. I would have stopped at nothing, though,
to prevent you. You must keep away from there!”
“And if we refuse?” asked Tom.
“Then you’ll have to take what comes!”
“But not from you!” exclaimed
Mr. Jenks. “We’re going to get rid
of you.”
The man’s face showed the alarm he felt.
“Oh, don’t worry,”
said Mr. Jenks, quickly, “we’re not going
to toss you overboard. We’re not as desperate
as your crowd. But we’re going to get rid
of you, and then go on before you can send any word
to your confederates. We’ll put you off
in the most lonesome spot we can find, and I guess
you’ll be some time getting back to civilization.
By that time we’ll have the secret of the diamonds.”
“You never will!” declared
the man, firmly. And he would say nothing more,
though by threats and promises Mr. Jenks tried to
get from him something about the men in with him, and
where the cave of the diamonds was located.
Heavily bound with ropes the man was
locked in a small closet, to be kept there until a
favorable spot was reached for letting him go.
Mr. Jenks’ plan, of dropping him down in some
place where he would have difficulty in sending on
word to his confederates was considered a good one.
Three days later, in crossing over
a lonely region, near the Nebraska National Forest,
Farley Munson, which was one of the names the spy
went by, was dropped off the airship, when it was
sent down to within a few feet of the earth.
“It will take you some time
to get to a telegraph office,” said Mr. Jenks,
as a package of food, and a flask of water was tossed
down to the stowaway. He shook his fist at those
in the airship, and shouted after them:
“You’ll never discover
the secret of Phantom Mountain!”
“Yes, we will,” declared
Tom, as he sent the Red Cloud high into the air again.
