over the missile. He glanced, quickly, at the enclosure, but not
one of the men on the other side of the wire was looking
his way.

Then the young captain, keeping briskly on his way, opened his
hand to glance down at his unexpected catch. It was a piece of
manila paper, wrapped around a stone.

Waiting only until he was some distance from the bull-pen, Dick
unwrapped the paper.

In printed characters, used undoubtedly to disguise handwriting,
was this message:

"Watch for all you're worth the carpenter who talks with Mock!"

"Now, why on earth should I interest myself in the affairs of
Greg's busted sergeant?" Dick wondered. "And what possible interest
can I have in any carpenter unless he's a friend of mine, or has
business with me?"

On the whole Prescott felt that he was lowering his own dignity
to attach any importance to an anonymous message, plainly from
a guardhouse prisoner. Yet he dropped the small stone and thrust
the scrap of paper into a pocket for future consideration should
he deem it worth while.
