ame of the airship, with the
planes and aluminum bag had been assembled, he looked in.

"We'll soon be flying through the clouds on your back," he remarked,
speaking to the apparatus as if it could understand. "I guess we'll
smash some records, too, if that engine works as well when it's
installed as it does now."

Tom had purchased the bolts, and was on his way back with them, when,
as he passed through one of the outlying streets of Mansburg, something
went wrong with his motor-cycle. He got off to adjust it, finding that
it was only a trifling matter, which he soon put right, when he was
aware of a man standing, observing him. Without looking up at the man's
face, the young inventor was unpleasantly aware of a sharp scrutiny. He
could hardly explain it, but it seemed as if the man had evil
intentions toward him, and it was not altogether unexpected on Tom's
part, when, looking up, he saw staring at him, Anson Morse, the leader
of the gang of men who had caused such trouble for him.

"Oh, it's you; is it?" asked Morse, an ugly scowl on his face. "I
thought I recognized you." He moved nearer to Tom, who straightened up,
and stood leaning on his wheel.

"Yes; it's me," admitted the lad.

gang. "You ought to be in jail now, instead of out; and if I could see
a policeman, I'd have you arrested for threatening me! That's against
the law!"

"Huh! I s'pose you think you know lots about the law," sneered Morse.
"Well, I tell you one thing, if you make any further trouble for me,
I'll--"

"I'll make all the trouble I can!" cried Tom, and he boldly faced the
angry man. "I'm not afraid of you!"

"You'd better be!" and Morse spoke in a vindictive manner. "We'll get
even with you yet, Tom Swift. In fact I've a good notion now to give
you a good thrashing for what you've done."

Before Tom was aware of the man's intention, Morse had stepped qui
