Roger or Moger."

"Foger!" cried Tom. "Was it Andy Foger?"

"Yes, that was it. Why, do you know him?" asked Mr. Berg in some
surprise.

"I should say so," replied Tom. "He was the cause of what might have
resulted in something serious for me," and the lad explained about
being imprisoned in the tank.

"You don't tell me!" cried Mr. Berg. "I had no idea he was that kind of
a lad. You see, his father is one of the directors of the firm by whom
I am employed. Andy came from home to spend a few weeks at the seaside,
and stopped at the same hotel that I did. He went off yesterday
afternoon, and I haven't seen him since, though he promised to go for a
ride with me. He must have come over here and entered your shop
unobserved. I remember now he asked me where the submarine was being
built that was going to compete with our firm's, and I told him. I
didn't think he was that kind of a lad. Well, since he's probably gone
back home, perhaps you will come for a ride with me, Tom."

"I'm afraid I can't go, thank you," answered the lad. "We are very busy
getting our submarine in shape for a trial. But I can imagine why Andy
left so hurriedly. He probably learned that a doctor had been summoned
for me, though, as it happened, I didn't need one. But Andy probably
got frightened at what he had done, and left. I'll make him more sorry,
when I meet him."

"Don't blame you a bit," commented Mr. Berg. "Well, I must be getting
back."

He hastened out to his auto, while Tom and his father watched the agent.

"Tom, never trust that man," advised the aged inventor solemnly.

"Just what I was about to remark," said his son. "Well, let's get back
to work. Queer that he should come here again, and it's queer about
Andy Foger."

Father and son returned to the machine shop, while Mr. Berg puffed away
in his auto. A little later, Tom having occasion to go to a building
near the boundary line of the cottage property which his father had
hired for the season, saw, through the hedge that bordered it, an
automobile standing in the road. A second glance showed him that it was
Mr. Berg's machine. Something had gone wrong with it, and the agent had
alighted to make an adjustment.

The young inventor was close to the man, though the latter was unaware
of his presence.

"Hang it all!" Tom heard Mr. Berg exclaim to himself. "I wonder what
they can be up to? They won't enter the Government contests, and they
won't say why. I believe they're up
