far as to post you on the details of the case?"

"He never did!" answered the caretaker.

"Is he liberal with his money?" asked George.

"He pays all the bills I send in," was the answer. "And seems to keep
this bum detective pretty well supplied with ten dollar bills."

"We may have to investigate this investigator!" laughed Sandy.

"Did Mr. Horton say anything to you about your lodgings while here?"
asked the caretaker. "It's getting too cold here for me, and we may
as well be shifting to warmer quarters."

"You said a short time ago," Will began, "that you rather thought we
ought to begin this search in the mine itself."

"That's my idea!" answered the caretaker.

"Do you think the boys are hiding in the mine?"

"Well, there are some things connected with the case which point in
that direction," replied Canfield. "For instance, there's a lot of
queer things going on underground."

"Ghosts?" demanded Tommy.

"You're not steering us up against a haunted mine, are you?" asked
George with a wink at his chum. "That would be too good to be true!"
