"An' that they've taken Powder River with them?"

"I'm doing better than guessin' about that. One of the party saw a bronc with an empty saddle an' tried to rope it. First time he missed, but he made good when he tried again."

"If I had yore imagination, Dud--"

"Straight goods. See here where the loop of the rope dragged along the top of the mud after the fellow missed his throw."

Bob saw the evidence after it had been pointed out to him. "But that don't prove he got Powder River next time he threw," he protested.

"Here's where that's proved." Dud showed him the impressions of two hoofs dug deep into the ground. "Powder River bucked after he was roped an'

tried to break away. The other horse, like any good cowpony does, leaned back on the rope an' dug a toe-hold."

"Where's Houck going?"

"Brown's Park likely, from the way they're headed."

"What'll we do?"

"Why, drap in on them to-night kinda casual an' say 'Much obliged for roundin' up our stray bronc for us.'"

This programme did not appeal to Bob. In that camp were two enemies of his. Both of them also hated Dud. Houck and Walker were vindictive. It was not likely either of them would forget what they owed these two young fellows.

"Maybe we'd better ride back an' tell the boss first," he suggested.

"Maybe we'd better not," Hollister dissented. "By that time they'd be so far ahead we'd never catch 'em. No, sir. We'll leave a note here for the boss. Tack it to this cottonwood. If we don't show up in a reasonable time he'll trail back an' find out what for not."

"That'd do us a lot of good if Houck had dry-gulched us."

Dud laughed. "You're the lad with the imagination. Far as Houck goes, an'

Bandy Walker, too, for that matter, I'll make you a present of the pair of 'em as two sure-enough bad eggs. But they've got to play the hands dealt 'em without knowin' what we're holdin'."

"They've prob'ly got rifles, an' we haven't."

"It's a cinch they've got rifles. But they won't dare use 'em. How do they know we're playin' this alone? First off, I'll mention that I sent Buck back to tell the boss we'd taken the trail after them. That puts it up to them to act reasonable whether they want to or not. Another thing.

We surprise 'em. Give the birds no chance to talk it over. Not knowin'

what to do, they do nothing. Ain't that good psycho-ology, as Blister says when he calls a busted flush?"

"Trouble is we're holdin' the busted flush."

"Sure, an' Houck'll figure we wouldn't 'a' trailed him unless we'd fixed the play right beforehand. His horse sense will tell him we wouldn't go that strong unless our cards was all blue. We're sittin' in the golden chair. O' course we'll give the birds a chance to save their faces--make it plain that we're a whole lot obliged to 'em for lookin' after Powder River for us."

Bob's sagging head went up. He had remembered Blister's injunction. "All right, Dud. Turn yore wolf loose. I'll ride along an' back the bluff."

They left the river and climbed to the mesa. The trail took them through a rough country of sagebrush into the hills of greasewood and pinon. In mid-afternoon they shot a couple of grouse scuttling through the bunch grass. Now and again they started deer, but they were not looking for meat. A brown bear peered at them from a thicket and went crashing away with an awkward gait that carried it over the ground fast.

From a summit they saw before them a thin spiral of smoke rising out of an arroyo.

"I reckon that's the end of the trail," Dud drawled. "We're real pleased to meet up with you, Mr. Houck. Last time I had the pleasure was a sorta special picnic in yore honor. You was ridin' a rail outa Bear Cat an'

being jounced up considerable."

"If he thinks of that--"

"He'll think of it," Dud cut in cheerfully. "He's gritted his teeth a lot of times over that happenstance, Mr. Houck has. It tastes right bitter in his mouth every time he recollects it. First off, soon as he sees us, he'll figure that his enemies have been delivered into his hand. It'll be up to us to change his mind. If you're all set, Sure-Shot, we'll drift down an' start the peace talk."

Bob moistened his dry lips. "All set."

They rode down the hillside, topped another rise, and descended into the draw where a camp was pitched.

A young fellow chopping firewood moved forward to meet them.

"There's Powder River with the broncs," Bob said in a low voice to his friend.

"Yes," said Dud, and he swung from the saddle.

"'Lo, fellows. Where you headed for?" the wood-chopper asked amiably.

Two men were sitting by the fire. They waited, in an attitude of listening. Dusk had fallen. The glow of the fire lighted their faces, but the men who had just ridden up were in the gathering darkness beyond the circle lit by the flames.

"We came to get Powder River, the bronc you rounded up for us," Hollister said evenly. "Harshaw sent us ahead. We're sure much obliged to you for yore trouble."

The larger of the two men by the fire rose and straddled forward. He looked at Dud and he looked at Bob. His face was a map of conflicting emotions.

"Harshaw sent you, did he?"

"Yes, sir. Bob had bad luck in the river an' the horse got away from him.

I reckon the pony was lightin' out for home when yore rope stopped the journey." The voice of Dud was cheerful and genial. It ignored any little differences of the past with this hook-nosed individual whose eyes were so sultry and passionate.

"So he sent you two fellows, did he? I'll say he's a good picker. I been wantin' to meet you," he said harshly.

"Same here, Houck." Bandy Walker pushed to the front, jerking a forty-five from its scabbard.

Houck's hand shot forward and caught the cowpuncher by the wrist. "What's bitin' you, Bandy? Time enough for that when I give the word."

The yellow teeth of the bow-legged man showed in a snarl of rage and pain. "I'd 'a' got Dillon if you'd let me be."

"Didn't you hear this guy say Harshaw sent them here? Use yore horse sense, man." Houck turned to Hollister. "Yore bronc's with the others.

The saddle's over by that rock. Take 'em an' hit the trail."

In sullen rage Houck watched Dud saddle and cinch. Not till the Slash Lazy D riders were ready to go did he speak again.

"Tell you what I'll do," he proposed. "Get down off'n yore horses, both o' you, an' I'll whale the daylight outa the pair of you. Bandy'll stay where he's at an' not mix in."

Hollister looked at Bandy, and he knew the fellow's trigger finger itched. There was not a chance in the world that he would stand back and play fair. But that was not the reason why Dud declined the invitation.

He had not come to get into trouble. He meant to keep out of it if he could.

"Last fellow that licked me hauled me down off'n my bronc, Mr. Houck,"

Dud answered, laughing. "No, sir. We got to turn down that invite to a whalin'. The boss gave us our orders straight. No trouble a-tall. I expect if it was our own say-so we might accommodate you. But not the way things are."

"No guts, either of you. Ain't two to one good enough?" jeered Houck angrily.
