"I was just leaving it when you came out," rejoined Roy, who, by this time, was fairly boiling over. "Under the present conditions, however, I think I shall continue to occupy it."

"You will, eh?" snarled out Dan Cassell, "then I'll show you how to vacate it—so!"

With the words he laid hands on the back of the chair and jerked it from under the young aviator. Roy, caught entirely off his guard, was flung to the floor of the porch. He was up in a flash, but as he rose to his feet Dan Cassell, evidently excited by what he deemed a great triumph, aimed a savage blow at him.

Jimsy was rushing to his assistance but the red-faced man suddenly blocked his path.

"Hold off, son! hold off!" he warned, "unless you want to get the same dose."

CHAPTER VIII.

ROY MAKES AN ENEMY.

In the meantime Roy had skillfully avoided Dan Cassell's blow, and was aggressively on the defensive. He was a lad who did not care for fighting, but notwithstanding was a trained boxer. Something of this seemed to dawn on Dan Cassell as the boy he sought to pummel dodged his attack with such cleverness.

For a moment Dan stood stock-still with doubled up fists and a scowl on his not unhandsome, though weak and vicious features. Then, with a bellow, he rushed upon Roy, who contented himself by sidestepping the furious onslaught.
