pile of bagging in the submarine shop, and his father and
the aeronaut were bending over him.

"Are you all right, Tom?" asked Mr. Swift.

"Yes--I--I guess so," was the hesitating answer. "Yes,"
the lad added, as the fresh air cleared his head. "I'll be
all right pretty soon. Have you seen Andy Foger?"

"Did he shut you in there?" demanded Mr. Swift.

Tom nodded.

"I'll have him arrested!" declared Mr. Swift "I'll go to
town as soon as you're in good shape again and notify the
police."

"No, don't," pleaded Tom. "I'll take care of Andy myself.
I don't really believe he knew how serious it was. I'll
settle with him later, though."

"Well, it came mighty near being serious," remarked Mr.
Sharp grimly. "Your father and I came back a little sooner
than we expected, and as soon as I got near the house I
heard your signal. I knew what it was in a moment. There
were Mrs. Baggert and Garret talking away, and when I asked
them why they didn't answer your call they said they thought
you were merely tinkering with the machinery. But I knew
better. It's the first time we ever had a use for 'forty-
seven,' Tom."
