"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 const.i.tution, and this would never have happened had he not been run down from overwork. That is the princ.i.p.al trouble. What he needs is rest; and then, with the proper remedies, he will be as well as before."
"But that strange lapse of memory, doctor?"
"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?"
"Yes; on a new wireless motor."
"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.
"Yes, I feel better," admitted Mr. Swift.
"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 pa.s.s 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--"
