"That's a Boy Scout call!" exclaimed Jack.

"Two columns of smoke," Frank said, "mean 'Help'! Jimmie couldn't have kindled two fires since he has been gone, could he?"

"Of course not," Jack replied. "That's Pat Mack, the red-headed rascal!"

"I bet he wishes he was back on Chatham Square!" observed Frank.

The boys waited ten minutes, but Jimmie did not make his appearance.

"He's in trouble!" cried Frank. "We better go and see what kind of a fix he's gotten into."

"It may be," Ned said, after a short pause, "that he has seen the call for help, and is making his way in that direction."

"That is just like him!" Jack burst out.

"Are we going in there after him?" Frank asked.

"We are likely to lose him in the thicket if we go," Ned cautioned, "and it seems to me that we ought to wait a short time. He is wise enough not to go butting into a camp."
