peaking of autos, did you see the one
Andy Foger has?"

"Yes; it's a beaut! Have you seen it?"

"Altogether at too close range. He nearly ran over me this morning,"
and the young inventor related the occurrence.

"Oh, Andy always was too fresh," commented Ned; "and since his
father let him get the touring car I suppose he'll be worse than
ever."

"Well, if he tries to run me down again he'll get into trouble,"
declared Tom, calling for a second cup of coffee.

The two chums began conversing on more congenial topics, and Ned was
telling of a new camera he had, when, from a table directly behind
him, Tom heard some one say in rather loud tones:

"The plant is located in Shopton, all right, and the buildings are
near Swift's house."

Tom started, and listened more intently.

"That will make it more difficult," one man answered. "But if the

that one of the men was the same he had seen in the post-office--the
man who answered the description of the one who had been inquiring
of Mr. Merton about the Swift shops.

"I'm going to keep my ears open," thought Tom as he went on eating
his dinner.

CHAPTER III.

IN A SMASH-UP

Though the young inventor listened intently, in an endeavor to hear
the conversation of the men at the table behind him, all he could
catch was an indistinct murmur. The strangers appeared to have
heeded the caution of one of their number and were speaking in low
tones.

Tom and Ned finished their meal, and started to leave the
restaurant. As Mr. Swift's son passed the table where the men sat
they looked up quickly at him. Two of them gave Tom but a passing
glance, but one--he whom the young inventor had noticed in the
post-offic
