"Come back here!" roared Bob, dropping the reins and taking up his weapon.
"If you fire again, I'll fire!" answered Sag Ruff, and the next instant a bullet whistled so close to Mark's head that he dodged and fell up against the side of the mule. Then Bob fired, but the shot merely grazed the gambler's arm and Soapy Gannon's shoulder.
"Hullo there!" came suddenly from a distance, and a moment later Si and Maybe Dixon burst into view, running at their best speed.
"Hullo yourself!" shouted Mark. "You've come in the nick of time."
"Didn't we see Sag Ruff and another man here?" questioned Si.
"You did."
"Where are they now?"
"Run away."
"Are you shot?"
