"Make tracks, you villains," he shouted, "or I'll put daylight through you." (This was a favorite expression of Randy's purloined from the life of Kit Carson.) Then, as retreating footsteps were heard, he lowered the weapon a little and pulled the trigger.

The thunderous report was followed by a yell of pain, and two voices hissed out dire threats of vengeance as the baffled men went hastily down the slope.

As Randy turned toward his companions Batters sprang at him and wrenched the weapon from his hands.

"Didn't I tell you not to shoot?" he cried. "Now you've gone an' hit Bug. I kinder feared it might be him, but I wasn't certain. That's him swearin' this very minute. Oh! I'll fix you for this."

Pushing Randy to one side and dashing the gun on the ground, Batters vanished in the darkness, yelling at the top of his voice, "Bug! Bug! it's me!"

The boys were overcome with terror and amazement. Who in the world was Bug, and why should Batters be so anxious about him?

"Why did you do that?" demanded Ned sternly. "If you have shot any one don't expect us to shield you."

Randy did not reply. He staggered into the tent and rolled over in helpless mirth.

"It—it was—a salt cartridge," he finally was able to gasp. "I had—three or four of them. I read how to make them—in a book. Didn't I pepper their legs nicely though.

"I don't care what it was," exclaimed Ned angrily. "You ought to be ashamed of yourself. You'll break up this trip yet with your foolishness."
