“No, I am not afraid of you, Paxton, and you know it,” answered Andy, promptly.

“Yes, you are afraid,” growled the other boy, and moved off. In a minute, however, he came back, and seizing hold of a long rope suspended from the gymnasium ceiling, commenced to swing upon it.

Jack and Pepper came in, and they stood talking to Andy as Paxton continued to swing back and forth, close at hand. Then Paxton changed his course, so that his feet struck Jack on the arm.

“Stop that, Paxton!” cried the young major, but before he could say more the cadet on the rope launched himself forward again, with feet extended, and caught Andy in the left wrist. The blow was so strong that the acrobatic youth was bowled over on the polished floor.

“Ouch, my wrist!” cried Andy, as he scrambled up. Then he gazed sharply at Paxton. “What did you do that for?” he demanded.

“Excuse me, I didn’t mean to touch you,” was the short answer, and Paxton dropped from the rope and started for the other end of the gymnasium.

“Hold on there!” cried Pepper, and ran after Paxton.

“What do you want, Pep Ditmore?”

“You struck Andy on purpose!”

“I did not!”
