“It’s no fun to throw lime dust around,” growled Phil, who was still rubbing his eyes. “For two pins, Nat Poole, I’d give you the thrashing of your life.”

“There will be no fighting done here!” cried Lieutenant Gebauer sternly.

“Perhaps you had a hand in this, Lieutenant?” said Dave quickly.

“Ha! do you accuse me, Porter?” and the other officer drew himself up proudly.

“I know there were two lots of that stuff came down on our heads. Did Poole throw both of them?”

“No, I didn’t!” was the quick reply. “I—I—” and then Nat stopped.

“I don’t see why you should make such a row over a little fun,” remarked Gebauer, puffing away at his cigarette. “It’s dull enough around here. We’ve got to stir things up a little.”

“Well, after this when you stir things up, you keep away from me,” said Dave coldly.

“Do you mean that as a threat, Porter?”

“I mean that as a warning.”
