amp to the mainland."

"Show us the way, and we will follow it."

"Come along, then, and in a few minutes we'll be out of here."

They entered the tunnel, and Old King Brady said to the broker:

"When I entered the Thirty-sixth street house the night you were
abducted, I found a curious dagger lying on the floor, and blood-stains
on the boards. These clews led me to suppose a murder had been
committed there. Do you know anything about those things?"

"Yes," replied the broker. "The dagger was one I had purchased as a

"Looks that way," replied the boy.

"We've got very little more to do now."

"Only to get the nippers on Mason and his black pal."

"Where in thunder could they have gone?"

"Let's notify the authorities along the line of the railroad in both
directions to keep a lookout for the pair."

Acting upon this suggestion, they quietly stole away, leaving the
reunited and happy father and daughter talking over past events.

Proceeding to Swamp Angel, and learning that neither of the villains
had yet put in an appearance there, they got the telegraph instrument
operating, and flashed a warning message all along the line.

News reached them that neither Mason nor Johnson had made any attempt
to get away on the cars yet.
