"Why, I mean that some of the breaker boys, out of work because of the
stoppage of operations, may have sneaked into the mine on purpose to
produce the impression that there are ghosts here."

"But ghosts wouldn't be giving signals of the Wolf Patrol, would
they?" asked Tommy.

"Not unless they were Scouts," replied the other.

"Oh, well, of course the kids would want to test us, wouldn't they,
seeing that we were only boys?"

"Well, we've discovered one thing by coming down here," said Tommy,
"and that is that there really are people in the mine who have no
business here."

"Then we may as well go back to bed," advised Sandy.

"Do you know how many corners we've turned since we came in here?"
asked Tommy.

"About a thousand, I guess," replied Sandy.

"Yes, and we'd have a fine old time getting out if you hadn't brought
that ball of twine!"

"Tell you what we'll do," Sandy said, as the boys turned their faces
down the gangway, "we'll pass around the next shoulder of rock and
then shut off our lights. Perhaps, the kids who gave the cry of the
pack in there will then show their light again."
