The committee turned it over and over, and were about to pass on it, when Mr.Wingate, who had been bending attentively over the bully's model, gave a sudden exclamation.
"Look here, gentlemen," he cried, pointing to a small tag which Jack had evidently forgotten to remove, "I think this is conclusive evidence.

Here is the label of the 'Manhattan Model Works' pasted right under this wing." "Somebody must have put it there.

It's a job those Boy Scouts put up on me," protested Tack.

"I made that model every bit myself." "I regret to say that we must regard the price tag as conclusive evidence that this machine comes from a store," said the professor sternly, handing Jack his unlucky model.

"You are disqualified for entering a machine not of your own workmanship.
"Stand back, please," he went on, as Jack tried to protest.
