"Bet he's mad," grinned Red. "An' there goes that Sharps—I could tell Hoppy's gun in a fusillade."

Crawling back up the gully to his first position Red peered out between some gramma grass tufts and again slid his rifle to his shoulder, laughing softly at the regular reports of the Sharps.

A puff of smoke enveloped his head and drifted behind him as he worked the lever of his rifle and, arising, he walked out towards the prostrate man and waved for his friend to join him. As he drew near the rustler struggled up on one elbow, and Red, running forward with his gun raised half-way to his shoulder, cried: "Don't make no gun-play, or I'll blow you apart! Where's th' rest of yore gang?"

"Go to h—l!" coughed the other, trying to get his Colt out, for his rifle was empty. He stiffened and fell flat.

Ten minutes later Hopalong and Red were riding southwest along a plain and well beaten trail, both silent and thoughtful. And at the end of an hour they saw the ragged top of Thunder Mesa towering against the horizon. They went forward cautiously now and took advantage of the unevenness of the plain, riding through barrancas and keeping close to chaparrals.

"Well, Red, I reckon we better stop," Hopalong remarked at last, his glasses glued to his eyes. "No use letting them see us."

"Is that smoke up there?" asked Red.

"Yes; an' there's somebody moving around near th' edge."

"I see him now."

"I reckon we know all that's necessary," Hopalong remarked. "That trail is enough, anyhow. Now we've got to get back to th' ranch without letting them fellers see us."
