"There's a man hiding there, Tom," reported his chum, a little later, after a cautious observation.
"I thought so. What's he doing?"
"Why he--by Jove! Tom, he's looking at us through opera glasses, like that other--"
"It isn't another, it's the same fellow!" whispered Tom. "It's the spy who was watching Andy! I'm going to see what's up," and he strode rapidly toward the street, at the curb of which was the tree that partly screened the man behind it.
Chapter III Queer Repairs
Quickly Tom Swift crossed the space between the airship, that was ready for a flight, and the tree. The man behind it had apparently not seen Tom coming, being so interested in looking at the airship, which was a wonderful craft. He was taken completely by surprise as Tom, stepping up to him, asked sharply:
"Who are you and what are you doing here?"
The man started so that he nearly dropped the opera glasses, which he had held focused on the aeroplane. Then he stepped back, and eyed Tom sharply.
"What do you want?" repeated our hero. "What right have you to be spying on that airship--on these premises?" The man hesitated a moment, and then coolly returned the glasses to his pocket. He did not seem at all put out, after his first start of surprise.
