As the three moved away George swung up the slope on the other side and came into view on the summit. The boy had cut a white pine climbing staff from which the small boughs had not been trimmed away, and Tommy saw that he was using this as a wig-wag flag. It was plain to the boy that George thoroughly understood the situation below.

The detectives growled out several vicious oaths as they saw the boy swinging his staff from the summit. They whispered together for a moment, and then Katz, leaving Tommy threatened by Cullen's revolver, moved toward the summit and the signaling boy.

When, in a moment, George looked down the slope to the east, he saw the detective creeping stealthily toward him. The officer was some, distance away, yet the boy knew that he was in danger from the gun in his hand. He gave one last swing and dropped his staff.

"Come down here!" shouted the detective. "I want to see you!"

"Come up here, then!" answered George. "What are you doing to my chum? You're always butting in on us boys!"

"If you don't come down instantly," shouted the angry detective, "I'll fill your hide full of lead! I've got you covered!"

Seeing by the malicious look on the face of the detective that he was really in earnest, George dropped quickly to the ground.
