how badly you have hurt my
friend here."

He stepped forward and aimed a hard blow at Davis with his left fist.
Davis stepped aside and the blow missed. At the same time Davis swung
hard with right and left and the second blow caught Jack on the helpless
right arm. Jack winced but said nothing. He was deadly cool, and he
advanced upon Davis smiling.

"Now," he said, "I'll give you an imitation of how I treat a dog like
you."

He backed Davis into a corner of the room by a series of single-arm
feints and then struck out heavily. Davis put up both arms to block the
blow but it did him no good. His guard was swept away as though it had
been a feather and the heavy blow crashed through and caught him in the
face.

Davis staggered back with arms covering his face protectingly and again
Jack struck him heavily between the eyes. Davis fell to the floor in a
heap, where he lay whining. Jack stood over him angrily.

"Get up!" he commanded quietly. "Get up and fight. I'm not through with
you yet."

Davis grovelled upon the floor, seeking to clasp the lad's knees.

"Get up!" commanded Jack again.

Davis made no move to rise.

Jack stretched out his uninjured arm and jerked the man rudely to his
feet.

"Put up your hands and fight," he ordered. "Don't show yourself the dog
you are!"

Davis did as Jack commanded and aimed a blow at the lad's head.

Jack promptly knocked him down again.

A second and a third time this was repeated; but after the last fall
Davis grovelled and moaned like a whipped child.

Jack gazed down at him in disgust.

"And I hadn't half begun," he said angrily. "However, I can't stand here
and knock down a man who will make no attempt to defend himself. I am
through with you now. You can go."

Slowly Davis raised himself to his feet and moved toward the door,
looking furtively about as he did so. As he reached the door, he sprang
suddenly outside with a loud cry. Jack sprang after him and seized his
arm just in time to deflect a bullet he would have fired from a revolver
he picked up without.

"I thought so," said Jack grimly. "I thought that was about your size. I
had it all figured out, only when it came to a show down I couldn't do
what I had intended. I had intended to let you pick up your gun, and
when you tried to shoot me, to kill you. But I can't do it. Get out of
here now before I change my mind."

Davis started to move along the hall, but at that moment there were
heavy foots
