The two lads on the loft listened intently. Though the cronies on the ground below them did not speak loudly, their voices came plainly to the listeners.
"Let's poke a hole in their gas bag," proposed Sam. "That will make them think they're not so smart as they pretend."
"Naw, we can't do that," answered Andy.
"Why not?" declared Pete.
"Because the bag's away up in the top part of the shed, and I'm not going to climb up there."
"You're afraid," sneered Sam.
"I am not! I'll punch your face if you say that again! Besides the thing that holds the gas is made of aluminum, and we can't make a hole in it unless we take an axe, and that makes too much noise."
"We ought to play some sort of a trick on Tom Swift," proposed Pete. "He's too fresh!"
Tom shook his fist at the lads on the ground, but of course they did not see him.
"I have it!" came from Andy.
"What?" demanded his two cronies.
"We'll cut some of the guy wires from the planes and rudders. That will make the airship collapse. They'll think the wires broke from the strain. Take out your knives and saw away at the wires. Hurry, too, or they may catch us."
