wanted to make. There were few persons abroad, and the young inventor thought he would have no one spying on him.
They located the big house of Andy's uncle without trouble. Going down a side street, they had a glimpse of a shed, built of new boards, standing in the middle of a large lot. About the structure was a new, high wooden fence, but as Tom and his friend passed along it they saw that a gate in it was open.
"I'm going in!" whispered Tom.
"Will it be safe?" asked Mr. Damon.
"I don't care whether it will be or not. I've got to know what Andy is doing. Come on! We'll take a chance!"
Cautiously they entered the enclosure. The big shed was dark, and stood out conspicuously in the moonlight.
"There doesn't seem to be any one here," whispered Tom. "I wonder if we could get a look in the window?"
"It's worth trying, anyhow," agreed Mr. Damon. "I'm with you, Tom."
They drew nearer to the shed. Suddenly Tom stepped on a stick, which broke with a sharp report.
"Bless my spectacles!" cried Mr. Damon, half aloud.
