"Here, here! What's going on over there?" shouted the Professor, starting on a run, while the other lads were laughing.

Chunky was sitting on the chest of his fallen adversary, Ned struggling desperately to throw the lad off.

Professor Zepplin grabbed him by the collar, jerking Stacy Brown from the fallen Pony Rider Boy.

Ned scrambled to his feet, and, with a sheepish grin on his face, proceeded to brush the dust from his clothes.

"Downed you, did he?" questioned Tad.

"It wasn't fair. I didn't know he was going to try."

"Neither did the Russians when the Japs sailed into them at Port Arthur," laughed Walter. "And they got what was coming to them."

"So did I. Chunky, I deserve more than you gave me. If you want to, beat me up some more."
