A MYSTERIOUS SIGNAL

"Good night!" ejaculated Harry, as the guide finished speaking. "You certainly have got us into a tight box now!"

"That's what I say," put in Jack, "you're a fine one!"

"Let me have your searchlight," commanded Ned, retaining his grasp on the other's cartridge belt, "hand it over quickly."

"I'll run the searchlight myself," declared the unknown in a crisp tone. "You've got my gun and I guess that's enough!"

"Yes, and I know how to use it, too," replied Ned.

"There, there, Ned, this isn't any time to start arguing," urged Jack, pacifically, "let's get out of here first of all."

"Second the amendment," laughed Ned, controlling himself with a slight effort, "I've got this fellow dead to rights, and if he will only help us with his searchlight, we will try to get outside quickly."

"Well, he's going to help us," volunteered Harry. "I'll see to that. Just notice this big rock I am holding."

"Don't get excited, hoys," urged the stranger. "I'm doing everything I can to get all of us out of this mess. Our troubles all came about simply because of the fact that we were not 'Prepared.'"
