"But that Jandel patent that Mr. Bartholomew is using out there on the H. & P. A. is probably the highest type of such motors. It is up to us to beat that. Fortunately I got a pa.s.s into the Jandel shops a few months ago and I studied at first hand the machine Mr. Bartholomew is using."

"Isn't that great!" cried Mary.

"Well, it helps some. I at least know in a general way the 'how' of the construction of the Jandel locomotive. It is simple enough. Too simple by far, I should say, to get both speed and power. We'll see," and he nodded his head thoughtfully.

Tom did not stay long with the girl, for it was already late in the evening when he had arrived at her house. As he got up to depart Mary's anxiety for his safety revived.

"I wish you would take care now, Tom. Those men may hound you."

"What for?" chuckled the young inventor. "They have the notes they wanted."

"But that very thing--the fact that you fooled them--will make them more angry. Take care."

"I have a means of looking out for myself, after all," said Tom quietly, seeing that he must relieve her mind. "I let that fellow get away with my wallet; but I won't let him hurt me. Don't fear."

She had opened the door. The lamplight fell across porch and steps, and in a broad white band even to the gate and sidewalk. There was a motor-car slowing down right before the open gate.

"Who's this?" queried Tom, puzzled.

A sharp voice suddenly was raised in an exclamatory explosion.

"Bless my breakshoes! is that Tom Swift? Just the chap I was looking for. Bless my mileage-book! this saves me time and money."

"Why, it's Mr. Wakefield Damon," Mary cried, with something like relief in her tones. "You can ride home in his car, Tom."

"All right, Mary. Don't be afraid for me," replied Tom Swift, and ran down the walk to the waiting car.

"Bless my vest b.u.t.tons! Tom Swift, my heart swells when I see you--"

"And is like to burst off the said vest b.u.t.tons?" chuckled the young fellow, stepping in beside his eccentric friend who blessed everything inanimate in his florid speech.

"I am delighted to catch you--although, of course," and Tom knew the gentleman's eyes twinkled, "I could have no idea that you were over here at Mary's, Tom."

"Of course not," rejoined the young inventor calmly. "Seeing that I only come to see her just as often as I get a chance."

"Bless my memory tablets! is that the fact?" chuckled Mr. Damon.

"Anyway, I wanted to see you so particularly that I drove over in my car tonight--"

"Wait a minute," said Tom, hastily. "Is this important?"

"I think so, Tom."

"Let me get something else off of my mind first, then, Mr. Damon," Tom Swift said quickly. "Drive around by Ned's house, will you, please? Ned Newton's. After I speak a minute with him I will be at your service.

"Surely, Tom; surely," agreed the gentleman.

The automobile had been running slowly. Mr. Damon knew the streets of Shopton very well, and he headed around the next corner. As the car turned, a figure bounded out of the shadow near the house line. Two long strides, and the man was on the running board of the car upon the side where Tom Swift sat. Again an ugly club was raised above the young fellow's head.

"You're the smart guy!" croaked the coa.r.s.e voice Tom had heard before.

"Think you can bamboozle me, do you? Up with 'em!"

"Bless my spark-plug!" gasped Mr. Wakefield Damon.

Either from nervousness or intention, he jerked the steering wheel so that the car made a sudden leap away from the curb. The figure of the stranger swayed.

Instantly Tom Swift struck the man's arm up higher and from under his own coat appeared something that bulked like a pistol in his right hand. He had intimated to Mary Nestor that he carried something with which to defend himself from highwaymen if he chose to. This invention, his ammonia gun, now came into play.

"Bless my failing eyesight!" exclaimed Mr. Damon, as he shot the motor-car ahead again in a straight line.

The man who had accosted Tom so fiercely fell off the running board and rolled into the gutter, screaming and choking from the fumes from Tom's gun.

"Drive on!" commanded the young inventor. "If he keeps bellowing like that the police will pick him up. I guess he will let us alone here-after."

"Bless my short hairs and long ones!" chuckled Mr. Damon. "You are the coolest young fellow, Tom, that I ever saw. That man must have been a highwayman. And it is of some of those gentry that I drove over to Shopton this evening to talk to you about."

Chapter IV

Much to Think About

Although it was now nearing ten o'clock on this eventful evening, Tom knew that he would find Ned Newton at home. When Mr. Damon's car stopped before the house there was a light in Ned's room and the front door opened almost as soon as Tom rang. Mr. Damon left the car and entered with the young inventor at his invitation.

"What's up?" was Ned's greeting, looking at the two curiously as he ushered them in. "I see this isn't entirely a social call," and he laughed as he shook the older man's hand.

"Bless my particular star!" exclaimed the latter excitedly. "Of all the thrilling adventures that anybody ever got into, it is this Tom Swift who cooks them up! Why, Newton! do you know that we have been held up by a highwayman within two blocks of this very house?"

"And that of course was Tom's fault?" suggested Ned, still smiling.

"It wouldn't have happened if he had not been with me," said Mr. Damon.

"I am curious," said Ned, as they seated themselves. "Who was the footpad? What drew his attention to you two? Tell me about it."

"Bless my suspender buckles!" exclaimed Mr. Damon. "You tell him, Tom.

I don't understand it myself, yet."

"I think I can explain. But whatever I tell you both, you must hold in secret. Father and I have been entrusted with some private information tonight and I am going to take you, Ned, and Mr. Damon, into the business in a confidential way."

"Let's have it," begged Newton. "Anything to do with the works?"

"It is," answered Tom gravely. "We are going to take up a proposition that promises big things for the Swift Construction Company."

"A big thing financially?"

"I'll say so. And it looks as though we were mixing into a conspiracy that may breed trouble in more ways than one."
