Mr. Swift was lying on the floor, where he had fallen, in
front of his bed, as he was preparing to retire. There was
no mark of injury upon him, and at first, as he knelt down
at his father's side, Tom was at a loss to account for what
had taken place.
"How did it happen? When was it?" he asked of Mrs.
Baggert, as he held up his father's head, and noted that the
aged man was breathing slightly.
"I don't know what happened, Tom," answered the
housekeeper, "but I beard him fall, and ran upstairs, only
to find him lying there, just like that. Then I called you.
Hadn't you better have a doctor?"
"Yes; we'll need one at once. Send Eradicate Tell him to
run--not to wait for his mule--Boomerang is too slow. Oh,
no! The telephone, of course! Why didn't I think of that at
first? Please telephone for Dr. Gladby, Mrs. Baggert. Ask
him to come as soon as possible, and then tell Garret
Jackson to step here. I'll have him help me get father into
bed."
The housekeeper hastened to the instrument, and was soon
in communication with the physician, who promised to call at
once. The engineer was summoned from another part of the
house, and then Eradicate was aroused.
Mrs. Baggert had the colored man help her get some kettles
of hot water in readiness for possible use by the doctor.
Mr. Jackson aided Tom to lift Mr. Swift up on the bed, and
they got off some of his clothes.
"I'll try to see if I can revive him with a little
aromatic spirits of ammonia," decided Tom, as he noticed
that his father was still unconscious. He hastened to
prepare the strong spirits, while he was conscious of a
feeling of fear and alarm, mingled with sadness.
Suppose his father should die? Tom could not bear to think
of that. He would be left all alone, and how much he would
miss the companionship and comradeship of his father none
but himself knew.
"Oh! but I mustn't think he's going to die!" exclaimed the
youth, as he mixed the medicine.
Mr. Swift feebly opened his eyes after Tom and Mr. Jackson
had succeeded in forcing some of the ammonia between his
lips.
"Where am I? What happened?" asked the aged inventor
faintly.
"We don't know, exactly," spoke Tom softly. "You are ill,
father. I've sent for the doctor. He'll fix you up. He'll be
here soon."
"Yes, I'm--I'm ill," murmured the aged man. "Something
hurts me--here," and he put his hand over his heart.
Tom felt a nameless sense of fear. He wished now that he
had insisted on his parent consulting a physician some time
before, when Mr. Swift first complained of a minor ailment.
Perhaps now it was too late.
"Oh! when will that doctor come?" murmured Tom
impatiently.
Mrs. Baggert, who was nervously going in and out of the
room, again went to the telephone.
"He's on his way," the housekeeper reported. "His wife
said he just started out in his auto."
Dr. Gladby hurried into the room a little later, and cast
a quick look at Mr. Swift, who had again lapsed into
unconsciousness.
"Do you think he--think he's going to die?" faltered Tom.
He was no longer the self-reliant young inventor. He could
meet danger bravely when it threatened himself alone, but
when his father was stricken he seemed to lose all courage.
"Die? Nonsense!" exclaimed the doctor heartily. "He's not
dead yet, at all events, and while there's life there's
hope. I'll soon have him out of this spell."
It was some little time, however, before Mr. Swift again
opened his eyes, but he seemed to gain strength from the
remedies which Dr. Gladby administered, and in about an hour
the inventor could sit up.
"But you must be careful," cautioned the physician. "Don't
overdo yourself. I'll be in again in the morning, and now
I'll leave you some medicine, to be taken every two hours."
"Oh, I feel much better," said Mr. Swift, and his voice
certainly seemed Stronger. "I can't imagine what happened. I
came upstairs, after Tom had received a visit from the
minister, and that's all I remember."
"The minister, father!" exclaimed Tom, in great amazement.
"The minister wasn't here this evening! That was Mr.
Gunmore, the aviation secretary. Don't you remember?"
"I don't remember any gentleman like that calling here
to-night," Mr. Swift said blankly. "It was the minister, I'm
sure, Tom."
"The minister was here last night, Mr. Swift," said the
housekeeper.
"Was he? Why, it seems like to-night. And I came upstairs
after talking to him, and then it all got black, and--and--"
"There, now; don't try to think," advised the doctor.
"You'll be all right in the morning."
"But I can't remember anything about that aviation man,"
protested Mr. Swift. "I never used to be that way--
forgetting things. I don't like it!"
"Oh, it's just because you're tired," declared the
physician. "It will all come back to you in the morning.
I'll stop in and see you then. Now try to go to sleep." And
he left the room.
Tom followed him, Mrs. Baggert and Mr. Jackson remaining
with the sick man.
"What is the matter with my father, Dr. Gladby?" asked Tom
earnestly, as the doctor prepared to take his departure.
"Is it anything serious?"
"Well," began the medical man, "I would not be doing my
duty, Tom, if I did not tell you what it is. That is, it is
comparatively serious, but it is curable, and I think we can
bring him around. He has an affection of the heart, that,
while it is common enough, is sometimes fatal.
"But I do not think it will be so in your father's case.
He has a fine constitution, and this would never have
happened had he not been run down from overwork. That is the
principal trouble. What he needs is rest; and then, with the
proper remedies, he will be as well as before."
"Oh, that is nothing. It is due to the fact that he has
been using his brain too much. The brain protests, and
refuses to work until rested. Your father has been working
rather hard of late hasn't he?"
"I thought so. Well, a good rest is what he needs, and
then his mind and body will be in tune again. I'll be around
in the morning."
Tom was somewhat relieved by the doctor's words, but not
very much so, and he spent an anxious night, getting up
every two hours to administer the medicine. Toward morning
Mr. Swift fell into a heavy sleep, and did not awaken for
some time.
"Oh, you're much better!" declared Dr. Gladby when he saw
his patient that day.
"And can't you remember about Mr. Gunmore calling?" asked
Tom.
The aged inventor shook his head, with a puzzled air.
"I can't remember it at all," he said. "The minister is
the last person I remember calling here."
Tom looked worried, but the physician said it was a common
feature of the disease from which Mr. Swift suffered, and
would doubtless pass away.
"And you don't remember how we talked about me building a
speedy aeroplane and trying for the ten-thousand-dollar
prize?" asked Tom.
"I can't remember a thing about it," said the inventor,
with a puzzled shake of his head, "and I'm not going to try,
at least not right away. But, Tom, if you're going to build
a new aeroplane, I want to help you. I'll give you the
benefit of my advice. I think my new form of motor can be
used in it."
"Now! now! No inventions--at least not just yet!" objected
the physician. "You must have a good rest first, Mr. Swift,
and get strong. Then you and Tom can build as many airships
as you like."
Mr. Swift felt so much better about three days later that
he wanted to get right to work planning the airship that was
to win the big prize, but the doctor would not hear of it.
Tom, however, began to make rough sketches of what he had in
mind changing them from time to time, He also worked on a
type of motor, very light, and modeled after one his father
had recently patented.
Then a new idea came to Tom in regard to the shape of his
aeroplane, and he worked several days drawing the plans for
it. It was a new idea in construction, and he believed it
would give him the great speed he desired.
"But I'd like dad to see it," he said. "As soon as he's
well enough I'll go over it with him."
That time came a week later, and with a complete set of
the plans, embodying his latest ideas, Tom went into the
library where his father was seated in an easy-chair. Dr.
Gladby had said it would not now harm the aged inventor to
do a little work. Tom spread the drawings out in front of
his father, and began to explain them in detail.
"I really think you have something great there, Tom!"
exclaimed Mr. Swift, at length. "It is a very small
monoplane, to be sure, but I think with the new principle
you have introduced it will work; but, if I were you, I'd
shape those wing tips a little differently."
"No, they're better that way," said Tom pleasantly, for he
did not often disagree with his father. "I'll show you from
a little model I have made. I'll get it right away."
Anxious to demonstrate that he was right in his theory,
Tom hurried from the library to get the model of which he
had spoken. He left the roll of plans lying on a small table
near where his father was seated.
"There, you see, dad," said the young inventor as he re-
entered the library a few minutes later, "when you warp the
wing tips in making a spiral ascent it throws your tail
wings out of plumb, and so--"
Tom paused in some amazement, for Mr. Swift was lying back
in his chair, with his eyes closed. The lad started in
alarm, laid aside his model, and sprang to his father's
side.
"He's had another of those heart attacks!" gasped Tom. He
was just going to call Mrs. Baggert, when Mr. Swift opened
his eyes. He looked at Tom, and the lad could see that they
were bright, and did not show any signs of illness.
"Well, I declare!" exclaimed the inventor. "I must have
dozed off, Tom, while you were gone. That's what I did. I
fell asleep!"
"Oh!" said Tom, much relieved. "I was afraid you were ill
again. Now, in this model, as you will see by the plans, it
is necessary--"
He paused, and looked over at the table where he had left
the drawings. They were not there!
"The plans, father!" Tom exclaimed. "The plans I left on
the table! Where are they?"
"I haven't touched them," was the answer. "They were on
that table, where you put them, when I closed my eyes for a
little nap. I forgot all about them. Are you sure they're
missing?"
"They're not here!" And Tom gazed wildly about the room.
"Where can they have gone?"
"I wasn't out of my chair," said Mr. Swift, "I ought not
to have gone to sleep, but--"
Tom fairly jumped toward the long library window, the same
one from which he had leaped to pursue Andy Foger. The
casement was open, and Tom noted that the screen was also
unhooked, It had been closed when he went to get the model,
he was sure of that.
"Look, dad! See!" he exclaimed, as he picked up from the
floor a small piece of paper.
"A sheet on which I did some figuring. It is no good, but
it was in with the plans. It must have dropped out."
"Do you mean that some one has been in here and taken the
plans of your new aeroplane, Tom?" gasped his father.
"That's just what I mean! They sneaked in here while you
were dozing, took the plans, and jumped out of the window
with them. On the way this paper fell out. It's the only
clue we have. Stay here, dad. I'm going to have a look." And
Tom jumped from the library window and ran down the path
after the unknown thief.
