Like a flash he brought the air rifle up for use. But there was nothing wicked in Dick Prescott. Even against such a foe as this big intruder; Dick felt that it would be wrong, wicked, to aim for the face of Mr. Fits.

Instead, Dick aimed for one of the fellow's legs. The little buckshot went where aimed, but through the thick trousers and underwear the little missile had no painful effect.

"Get back, you lunatic!" quivered Dan, in the same instant, drawing the arrow to the head, ready to let drive.

But at that interesting moment another of the Grammar School boys saved the situation. It was Tom Reade, who, just as Mr. Fits started forward, and was still moving, thrust the crowbar between his legs.

Flop! Fits struck the earthen floor rather heavily, the chair flying over the head of Dick Prescott and landing beyond.

"Good chance!" cheered Harry Hazelton, bringing down his stick of firewood with a blow that resounded.

Tom Reade now raised the crowbar once more, standing where he could aim at the fellow's head. Tom was both too generous and too tender hearted to have struck a human being over the head with such an implement, even had Fits given provocation.

"Don't get up, Mr. Fits," warned Dick, still gripping the air rifle. "If you start to do so, it will be the signal for something to happen."

Their nerves tense from the peril of their surroundings, the Grammar School boys, none of whom were cowards at heart, even though they were pretty young, looked positively fierce in the eyes of the prostrate foe.

"You don't any of you dare hit me," he sneered, with an attempt at bluster.
