The two lads came from Tom's particular workshop. As the young inventor closed the door he started suddenly, as he snapped shut the lock.

"What's the matter?" asked Ned quickly.

"I thought I heard a noise," replied Tom.

They both listened. There was a slight rustling in some bushes near the shop.

"It's a dog or a cat," declared Ned.

Tom took several cautious steps forward. Then he gave a spring, and made a grab for some one or something.

"Here! You let me be!" yelled a protesting voice.

"I will when I find out what you mean by sneaking around here," retorted Tom, as he came back toward Ned, dragging with him a lad. "It wasn't a dog or a cat, Ned," spoke the young inventor. "It's Sam Snedecker," and so it proved.

"You let me alone!" demanded Andy Foger's crony. "I ain't done nothin' to you," he whined.

"Here, Ned, you hold him a minute, while I make an investigation," called Tom, handing his prisoner over to his chum. "Maybe Pete or Andy are around."
