"Fritz isn't asleep," muttered Frank.

"He's right on the job with his fireworks," agreed Bart.

"Maybe he has his suspicions that we're going to give him a little surprise party," remarked Billy, "and that's his way of telling us that he's ready to welcome us with open arms."

"I don't think there'll be any gun fire this time before we go over the top," ventured Frank.

"What do you mean?" asked Bart in surprise, as he turned his head toward his chum.

"Do you know anything?" queried Tom.
