" luck we're in to be here, Tom!" murmured Jack.

Carl Potzfeldt had again entered the house and closed the door; and the air service boys could no longer hear the car speeding along the road. Jack was quivering all over with excitement. The events that had just come to their attention filled him with a sensation of wonder approaching awe.

"It certainly is strange how we've stumbled on this nest of spies," admitted Tom.

"And the paper he gave the captain—it must have been a message in cipher that an incoming pigeon brought from back of our lines, eh, Tom?"

"I guess it was, Jack. We could see it was only a small scrap of paper, thin paper at that; but both of them handled it as if it were pretty valuable."

Jack was chuckling, such a queer proceeding that Tom could not help noticing it, and commenting on it.

"What's struck you as funny now?" he asked, puzzled to account for this sudden freak on the part of his companion.
