The young inventor stood almost spellbound for a few moments.
Then recovering himself he made a dash for the door through which
the mysterious man had disappeared. Tom saw him sprinting down
the road, and was half-minded to take after him, but a cooler
thought warned him that he had better not.
"He may be one of those men who are on Mr. Jenks' trail,"
reasoned Tom, in which case it might not be altogether safe to
attempt to stop him, and make him explain. Or he may be a
lunatic, and in that case it wouldn't be altogether healthy to
interfere with him.
"I'll just let him go, and tell Mr. Jenks about him when he
comes to-night. But I must warn Rad never to let him in here
again. He might damage the airship."
Calling to the colored man, Tom pointed to the stranger, who
was almost out of sight down the road, and said earnestly:
"I sho do, Massa Tom, but I sorter has t' strain my eyes t' do
it. He's goin' laik my mule Boomerang does when he's comm' home
t' dinnah."
"That's right, Rad. Well, never let that man set foot inside
our fence again! If he comes, and I'm home, call me. If I'm away,
call dad or Mr. Jackson, and if you're here alone, drive him
away, somehow."
"I will, Massa Tom!" exclaimed the colored man, earnestly, "an'
if I can't do it alone, I'll get Boomerang t' help. Once let dat
ar' mule git his heels on a pusson, an' dat pusson ain't goin' t'
come bodderin' around any mo'--that is, not right away."
"I believe you, Rad. Well, keep a lookout for him, and don't
let him in," and with that Tom entered the house to think over
matters. They were beginning to assume an aspect he did not
altogether like. Not that Tom was afraid of danger, but he
preferred to meet it in the open, and the warning, or threat, of
the mysterious man disquieted him.
When Mr. Swift came home, a little later, his son told him of
the midnight interview with Mr. Jenks, for, up to this time, the
aged inventor was unaware of it, and Tom also gave an account of
the diamonds, speaking of their value.
"And do you propose to go to Phantom Mountain, in search of the
makers of these gems, Tom?" asked Mr. Swift.
"Well, Mr. Jenks will go, of course, and I've no doubt but that
if I mention the prospective trip to Mr. Damon, that he'll bless
his skating cap, or something like that, and come along."
"I suppose so, Tom, and I'd like to have you take him. But I
think you'll need some one else."
"Because, from what you have told me, you are going out to a
dangerous part of the country, and you may have to deal with
unscrupulous men. Three of you are hardly enough to cope with
them. You ought to have at least another member of your party. If
I was not busy on my invention of a new wireless motor I would go
along, but I can't leave. You might take Mr. Jackson."
"Rad would get homesick for his mule Boomerang, and I'd have to
bring him back just when we'd found the diamonds," replied the
young inventor. "No, we'll have to think of some one else. I'll
ask Mr. Damon, and then I'll consider matters further. I expect
to see Mr. Jenks to-night, and he may have some one in mind."
"Perhaps that will be a good plan. Well, Tom, I trust you will
take good care of yourself, and not run into unnecessary danger.
Is the Red Cloud in good shape for the voyage?"
"It needs looking over. I'm going to get right at it."
"It's a pretty indefinite sort of a quest you're going on, Tom,
my son. How do you expect to find Phantom Mountain?"
"Well, it's going to be quite a task. In the first place we'll
head for Leadville, Colorado, and then we'll go to Indian Ridge
and make some inquiries. We may get on the track of the place
that way. If we don't, why I'll take the airship up as high as is
necessary and sort of prospect until we see that big cliff that's
shaped like a head. That will give us something to go by."
"Well, do the best you can. If you can discover the secret of
making diamonds it will be a valuable one."
"I guess it will, dad; and Mr. Jenks is entitled to know it,
for he paid his good money to that end. He has promised to go
halves with me, as payment for the use of the airship, and I must
say the two diamonds he gave me last night have proved very
valuable."
"Two diamonds, Tom? You only showed me one, an uncut gem"; and
Mr. Swift looked at his son.
"Oh, the other--er--the other is--I left it with a jeweler,"
and Tom blushed a trifle, as he thought of the present he
contemplated making to Mary Nestor.
That afternoon, as Tom was out in the shed of the Red Cloud
looking over the airship, to see what would be necessary to do to
it in order to get it in shape for a long trip, he heard voices
outside.
"Yes--yes, I know the way in perfectly well," he caught. "You
needn't bother to come, my good fellow. Just step this way, and
I'll show you something worth seeing."
"I wonder if it's that mysterious man coming back?" thought
Tom. He dropped the tool he was using, and hurried to the door.
As he approached it he heard the voice continue.
"Why bless my shoe laces, Mr. Parker! You'll see a wonderful
airship, I promise you. Wonderful! Bless my hatband, but I hope
Tom is here!"
"Mr. Damon!" exclaimed our hero, as he recognized the tones of
his eccentric friend. "But who is with him?"
A moment later he caught sight of the gentleman who was always
blessing himself, or something. Behind him stood another man,
whose features Tom could not see plainly.
"Hello, Tom Swift!" called Mr. Damon. "Looking over the Red
Cloud, eh? Does that mean you're off on another trip?"
"Were you? Bless my heart, I'm glad you thought of me. You
don't by any possible chance want another person; do you?"
"We were thinking of having four in the party, Mr. Damon," and
Tom wondered who was with his eccentric friend.
"Then bless my election ticket! This is the very chance for
you, Mr. Parker!" cried Mr. Damon. "Will you go with us? It will
be just what you need," and Mr. Damon stepped aside, revealing to
Tom the features of Mr. Ralph Parker, the scientist who had
correctly predicted the destruction of Earthquake Island.
