"Please don't interfere. This is a perfectly friendly little argument. We've got to fight it out."

The men laughed uproariously.

"You look the part, both of you. Go it, then, if you've got to fight. We'll see that each of you gets fair play."

But the boys did not hear. They were at it again and with a savageness that had not marked their fighting before. Two blows delivered at the same instant landed both boys on their backs on the ground.

The miners yelled for sheer joy.

Bounding to their feet, the combatants went at it again hammer and tongs; and, though they were mere lads, it is doubtful if the spectators ever had witnessed a more scientific battle with fists. The lads were side-stepping and dancing in their stocking feet, not heeding the sharp pieces of rock and ore that cut into their feet, drawing the blood at almost every step.

They had battled steadily for over ten minutes. The face of each was covered with blood and it was with difficulty that the lads were able to see at all. They had barely one set of good eyes between them. Jarvis was getting more and more desperate. Try as he might his superior strength was not equal to the task of putting Steve Rush down and out. For every blow delivered Bob got a return that he felt all over his body from his head to his feet.

At last Bob thought he saw an opening to deliver a knock-out blow. He let go with all his strength. The blow struck nothing more substantial than thin air. Then, like a bolt of lightning, the fist of Steve Rush shot out, catching Jarvis under the nose, lifting the larger boy from his feet, sending him crashing against the shore wall of the drift.

"That settles him," shouted the spectators. "My, what a wallop! That would have knocked down one of the mules in number seven level. I'll bet he doesn't wake up in——"

Bob Jarvis was already awake. Despite the terrific blow under which he had gone down he was quickly on his feet. It was observed that he staggered a little. Both boys were beginning to show their weariness, though Jarvis exhibited more of this than did Steve.
