"Well," replied Mr. Damon, "I paid two hundred and fifty dollars last week. I have ridden a hundred miles on it. That is at the rate of two dollars and a half a mile--pretty expensive riding. But if you are in earnest I will let you have the machine for fifty dollars, and then I fear that I will be taking advantage of you."
"I"ll give you fifty dollars," said Tom quickly, and Mr. Damon exclaimed:
"Bless my liver--that is, if I have one. Do you mean it?"
Tom nodded. "I"ll fetch you the money right away," he said, starting for his room. He got the cash from a small safe he had arranged, which was fitted up with an ingenious burglar alarm, and was on his way downstairs when he heard his father call out:
"Here! What do you want? Go away from that shop! No one is allowed there!" and looking from an upper window, Tom saw his father running toward a stranger, who was just stepping inside the shop where Mr.
Swift was constructing his turbine motor. Tom started as he saw that the stranger was the same black-mustached man whom he had noticed in the post-office, and, later, in the restaurant at Mansburg.
CHAPTER V.
MR. SWIFT IS ALARMED
Stuffing the money which he intended to give to Mr. Damon in his pocket, Tom ran downstairs. As he pa.s.sed through the living-room, intending to see what the disturbance was about, and, if necessary, aid his father, the owner of the broken motor-cycle exclaimed:
"What"s the matter? What has happened? Bless my coat-tails, but is anything wrong?"
"I don"t know," answered Tom. "There is a stranger about the shop, and my father never allows that. I"ll be back in a minute."
"Take your time," advised the somewhat eccentric Mr. Damon. "I find my legs are a bit weaker than I suspected, and I will be glad to rest a while longer. Bless my shoelaces, but don"t hurry!"
Tom went into the rear yard, where the shops, in a small cl.u.s.ter of buildings, were located. He saw his father confronting the man with the black mustache, and Mr. Swift was saying:
"What do you want? I allow no people to come in here unless I or my son invites them. Did you wish to see me?"
"Are you Mr. Barton Swift?" asked the man.
"Yes, that is my name."
"The inventor of the Swift safety lamp, and the turbine motor?"
At the mention of the motor Mr. Swift started.
"I am the inventor of the safety lamp you mention," he said stiffly, "but I must decline to talk about the motor. May I ask where you obtained your information concerning it?"
"Why, I am not at liberty to tell," went on the man. "I called to see if we could negotiate with you for the sale of it. Parties whom I represent--"
At that moment Tom plucked his father by the sleeve.
"Dad," whispered the youth, "I saw him in Mansburg. I think he is one of several who have been inquiring in Mr. Merton"s shop about you and your patents. I wouldn"t have anything to do with him until I found out more about him."
"Is that so?" asked Mr. Swift quickly. Then, turning to the stranger, he said: "My son tells me--"
But Mr. Swift got no further, for at that moment the stranger caught sight of Tom, whom he had not noticed before.
"Ha!" exclaimed the man. "I have forgotten something--an important engagement--will be back directly--will see you again, Mr. Swift--excuse the trouble I have put you to--I am in a great hurry," and before father or son could stop him, had they any desire to, the man turned and walked quickly from the yard.
Mr. Swift stood staring at him, and so did Tom. Then the inventor asked:
"Do you know that man? What about him, Tom? Why did he leave so hurriedly?"
"I don"t know his name," replied Tom, "but I am suspicious regarding him, and I think he left because he suddenly recognized me."
Thereupon he told his father of seeing the man in the post-office, and hearing the talk of the same individual and two companions in the restaurant.
"And so you think they are up to some mischief, Tom?" asked the parent when the son had finished.
"Well, I wouldn"t go quite as far as that, but I think they are interested in your patents, and you ought to know whether you want them to be, or not."
"I most certainly do not--especially in the turbine motor. That is my latest invention, and, I think, will prove very valuable. But, though I have not mentioned it before, I expect to have trouble with it. Soon after I perfected it, with the exception of some minor details, I received word from a syndicate of rich men that I was infringing on a motor, the patent of which they controlled."
"This surprised me for two reasons. One was because I did not know that any one knew I had invented the motor. I had kept the matter secret, and I am at a loss to know how it leaked out. To prevent any further information concerning my plans becoming public, I sent you to Mansburg to-day. But it seems that the precaution was of little avail. Another matter of surprise was the information that I was infringing on the patent of some one else. I had a very careful examination made, and I found that the syndicate of rich men was wrong. I was not infringing. In fact, though the motor they have is somewhat like mine, there is one big difference--theirs does not work, while mine does. Their patents are worthless."
"Then what do you think is their object?"
"I think they want to get control of my invention of the turbine motor, Tom. That is what has been worrying me lately. I know these men to be unscrupulous, and, with plenty of money, they may make trouble for me."
"But can"t you fight them in the courts?"
"Yes, I could do that. It is not as if I was a poor man, but I do not like lawsuits. I want to live quietly and invent things. I dislike litigation. However, if they force it on me I will fight!"
exclaimed Mr. Swift determinedly.
"Do you think this man was one of the crowd of financiers?" asked Tom.
"It would be hard to say. I did not like his actions, and the fact that he sneaked in here, as if he was trying to get possession of some of my models or plans, makes it suspicious."
"It certainly does," agreed Tom. "Now, if we only knew his name we could--"
He suddenly paused in his remark and sprang forward. He picked up an envelope that had dropped where the stranger had been standing.
"The man lost this from his pocket, dad," said Tom eagerly. "It"s a telegram. Shall we look at it?"
"I think we will be justified in protecting ourselves. Is the envelope open?"
"Yes."
"Then read the telegram."
Tom drew out a folded yellow slip of paper. It was a short message.
He read:
""Anson Morse, Mansburg. See Swift to-day. Make offer. If not accepted do the best you can. Spare no effort. Don"t give plans away.""
"Is that all?" asked Mr. Swift.
