The gun flashed into Slim's hand and boomed. El Sangre bolted straight into the air and landed on legs of jack-rabbit qualities that flung him sidewise. The hand and voice of Terry quieted him, while the others stood around grinning with delight at the fun and at the beautiful horsemanship.

"But what'll he do if you pull a gun yourself?" asked Joe Pollard, showing a sudden concern.

"He'll stand for it—long enough," said Terry. "Try him!"

There was a devil in Slim that morning. He snatched up a shining bit of quartz and hurled it—straight at El Sangre! There was no warning—just a jerk of the arm and the stone came flashing.

"Try your gun—on that!"

The words were torn off short. The heavy gun had twitched into the hand of Terry, exploded, and the gleaming quartz puffed into a shower of bright particles that danced toward the earth. El Sangre flew into a paroxysm of educated bucking of the most advanced school. The steady voice of Terry Hollis brought him at last to a quivering stop. The rider was stiff in the saddle, his mouth a white, straight line.

He shoved his revolver deliberately back into the holster.

The four men had drawn together, still muttering with wonder. Luck may have had something to do with the success of that snapshot, but it was such a feat of marksmanship as would be remembered and talked about.

"Dugan!" said Terry huskily.

Slim lunged forward, but he was ill at ease.
