"Why, they're safer than street cars!" declared Tom with a laugh.
"Just think how often street cars collide, and you never heard of an
aeroplane doing that."

"No, but think what happens when they fall."

"That's it!" cried Tom gaily, "when they fall you don't have time to
think. But is dinner ready? I'm hungry."

"Never saw you when you weren't." commented the housekeeper
laughing. "Yes, you can sit right down. We won't wait for your
father. He said he'd be late as he wants to find something about his
gyroscope. I never did any such people as inventors for spoiling
their meals," she added as the put dinner on the tab's.

Mr. Swift came in before his son had finished.

"Was Andy Foger here to see me again?" he asked.

"No, why do you ask?" inquired Tom quickly.

"I just saw him out by the aeroplane shed, and--"

Tom jumped up without another word, and hurried to where his sky
racer rested on its bicycle wheels.

He breathed more easily when he saw that Andy was not in sight, and
a hurried inspection of the aeroplane did not disclose that it had
been tampered with.
