"Without going back to camp to tell the boys?" asked Jimmie. "We have been gone a long time now, remember. They will be worrying about us pretty soon."

"But we ought to go right now!" insisted Teddy. "The boy may be in trouble."

"Something else coming!" cried Jimmie, then. "See that blazing stick working overtime? He's going to talk in the Myer code! Now count right and left."

"It should embrace an arc of ninety degrees, starting at the vertical and returning to it without pause, and should be made in a plane exactly at right angles to the line connecting the two stations.

"And No. 2 motion is the same, only on the left side. And three is the same, only the signal goes to the ground and comes back to the vertical! Now I've got it! Then he wig-wags again I'll tell you what he says. You read, too, and see if we agree."

"One to the right!" cried Jimmie, "and two to the left!"
