Mack Nolan rolled another cigarette, lighted it and flipped the match into the campfire. He smoked it down to the last inch, staring into the fire and saying nothing the while. When the cigarette stub followed the match, he leaned back upon one elbow and began tracing a geometrical figure in the sand with a stick.

"Ryan," he said abruptly, "you're square and I know it. The very nature of my business makes me cautious about trusting men--but I'm going to trust you." He stopped again, taking great pains with the point of a triangle he was drawing.

Casey knocked the ashes out of his pipe against a rock. "Puttin' it that way, Mr. Nolan, the man's yet to live that Casey Ryan ever double-crossed. Cops I got no use for; nor yet bootleggers. Whether I got any use for you, Mr. Nolan, I can say better when I've heard yuh out. A goat I've been for the last time. But I'm willin' to HEAR yuh out--and that there's more'n what I'd uh said this morning."

"And that's fair enough, Ryan. If you jumped into things with your eyes shut, I don't think I'd want you with me."

Casey squirmed, remembering certain times when he had gone too headlong into things.

"I'm going to ask you, Ryan, to tell me the whole story of this car and its load of whisky. Before you do that, I'll tell you this much to show good faith and prove to you how much I trust you: I'm an officer, and my special work right now is to clean up a gang of bootleggers and the crooked officers who are protecting them. What I know about your case leads me to believe that you've run afoul of them and that you're the man I've been looking for that can help me set a trap for them.

Would you like to do that?"

"If it's that bunch you're after, Mr. Nolan, I'd ruther land 'em in jail than to find a ledge of solid gold ten feet thick an' a mile long.

One thing I'd like to know first. Are yuh or ain't yuh huntin' mules?"

Mack Nolan laughed. "I am, yes. But the mule I'm hunting is white!"

Casey studied that until he had the fresh pipeful of tobacco going well. Then he looked up and grinned understandingly.

"So it's White Mule you're trailin'." He kicked a stub of greasewood branch back into the flames and laughed. "Well, the tracks is deep an'

plenty, and if that's the trail you're takin', I'm with yuh. You ain't a cop--leastways you don't spread your arms every time you turn around.

Gosh, I hate them wing-floppin' kind! They's one thing an' one only that I hate worse--an' that's bootleggers an' moonshiners. If you got a scheme to give them cusses their needin's, you can ask anybody if Casey Ryan ain't the feller you can bank on."

"Yes. That's what I've been thinking. Now, I wish you'd tell me exactly what you've been up against. Don't leave out anything, however trivial it might seem to you."

Wherefore, Casey sat with the firelight flickering across his seamed, Irish face and told the story of his wrongs. Trivial details Nolan had asked for--and he got them with the full Casey Ryan flavor. Even the old woman who rocked, Casey pictured--from his particular angle. Mack Nolan sat up and listened, his eyes steady and his mouth, that had curved to laughter many times during the recital, once more firm and somewhat pitiless when Casey finished.

"This Smiling Lou; you'd know him again, of course?"

"Know him! Say, I'd know him after he'd fried a week in h.e.l.l!" Casey's tone left no doubt of his meaning.

"And I suppose you could tell this man Kenner a mile off and around a corner. Now, I'll tell you what I want you to do, Casey. This may jar you a little--until I explain. I want you--" Mack Nolan paused, his lips twitching in a faint smile--"to do a little bootlegging yourself."

"Yuh--WHAT?" In the firelight Casey's eyes were seen to bulge.

"I want you to bootleg this whisky you've got in the car." Nolan's eyes twinkled. "I want you to go back and peddle this booze, and I want you to do it so that Smiling Lou or one of his bunch will hold you up and highjack you. Do you see what I mean? You don't--so I'll tell you.

We'll put it in marked bottles. I have the bottles and the seals and labels for every brand of liquor to be had in the country to-day. With marked money and marked bottles, we ought to be able to get the goods on that gang."

Casey thought of something quite suddenly and held out an imperative, pointing finger.

"There's something else that feller told me was in the car!" he cried agitatedly. "He said he had forty pints of French champagne cached in a false bottom under the front seat. And he said the front cushion had a blind pocket around the edges that was full uh dope. Hop, he called it."

Mack Nolan whistled under his breath.

"And he turned the whole outfit over to you for sixteen hundred dollars or so?" He stared thoughtfully into the fire. Abruptly he looked at Casey.

"What the deuce had you done to him, Ryan?" he asked, with a quizzical intentness. "He must have been scared stiff, to let go of all that stuff for sixteen hundred. Why, man, the 'junk'--that's dope--alone must be worth more than that. And the champagne--forty pints, you say?

He ought to get twenty dollars a pint for that. Figure it yourself. I hope," he added seriously, "the fellow wasn't too scared to show up again."

"Well," Casey said grimly, "I dunno how scart he is--but he knows darn'

well I'll kill 'im. I told im I would."

Again Mack Nolan laughed. "Catching's much better than killing, Ryan.

It hurts a man worse, and it lasts a heap longer. What do you say to turning in? To-morrow we'll have a full day at my private bottling works."

They moved their cooking outfit down near the Ford for safety's sake.

While it was wholly improbable that the car would be robbed in the night, Mack Nolan was a man who took as few chances as possible. It happened that the excavation Casey had so hopefully made that morning formed a convenient level for their bed; wherefore they spread it there, talking in low tones of their plans until they went to sleep.

CHAPTER FIFTEEN

Dawn was just thinning the curtain of darkness when Nolan woke Casey with a shake of the shoulder.

"I think we'd better be moving from here before the world's astir. You can back on down this draw, Ryan, and strike an old trail that cuts over the ridge and up the next gulch to an old, deserted mine where I've made headquarters. It isn't far, and we can have breakfast at my camp."

Casey swallowed his astonishment, and for once in his life he did as he was told without argument.

Mack Nolan's camp was fairly accessible by roundabout trail with a few tire tracks to point the way for Casey. Straight across the ridges, it would not have been more than two miles to Juniper Wells. Nevertheless not one man in a year would be tempted to come this way, unless it were definitely known that some one lived here.

As the camp of a man who was prospecting for pastime rather than for a grubstake, the place was perfect. Mack Nolan had taken possession of a cabin dug into the hill at the head of a long draw. A brush-covered shed of makeshift construction sheltered a car of the ubiquitous Ford make. Fifty yards away and in full sight of the cabin, the mouth of a tunnel yawned blackly under a rhyolite ledge.

Casey swept the camp with an observant glance and nodded approval as and stopped before the cabin.

"As a prospector, Mr. Nolan, I'll say 'tis a fine layout you got here.

An' tain't the first time an honest-lookin' mine has been made to cover things far off from minin'. Like the Black b.u.t.te bunch, f'r instance.

But if any one was to ride up on yuh unexpected here, I'll say yuh could meet 'em with a grin an' feel easy about your secrets."

"That's praise indeed, coming from an old hand like you," Nolan declared. "Now I'll tell you something else. With Casey Ryan in the camp the whole thing's twice as convincing. Come in. I want to show you what I call an artistic interior."

Grinning, Casey followed him inside and exclaimed profanely in admiration of Mack Nolan's genius. The cabin showed every mark of the owner's interest in the geologic formation of that immediate district.

On the floor along the wall lay specimens of mineralized rock, a couple of prospector's picks, a single-jack and a set of drills; a sample sack, grimed and with a hole in the corner mended by the simple process of gathering the cloth together around it and tying it tightly with a string, hung from a nail above the tools. On the window sill were specimens of ore; two or three of the pieces showed a richness that lighted Casey's eyes with the enthusiasm of an old prospector. Mining journals and a prospector's manual lay upon a box table at the foot of the bunk. For the rest, the cabin looked exactly what it was--the orderly home of a man quite accustomed to primitive living far off from his fellows.

They had a very satisfactory breakfast cooked by Mack Nolan from his own supplies and eaten in a leisurely manner while Nolan talked of primary formations and secondary, and of mineral intrusions and breaks.

Casey listened and learned a few things he had not known, for all his years of prospecting. Mack Nolan, he decided, could pa.s.s anywhere as a mining expert.

"And now," said Nolan briskly, when he had hung up the dishpan and draped the dishcloth over it to dry, "I'll show you the bottling works.

We'll have to do the work by lantern-light. There's not one chance in fifty that any one would show up here--but you never can tell. We could get the stuff out of sight easily enough while the car was coming up the gulch. But the smell is a different matter. We'll take no chances."

At the head of the bunk, a curtained s.p.a.ce beneath a high shelf very obviously did duty as a wardrobe. A leather motor coat hung there, one sleeve protruding beyond the curtain of flowered calico. Other garments bulged the cloth here and there. Nolan, smiling over his shoulder at Casey, nodded and pushed the clothing aside. A door behind opened inward, admitting the two into a small recess from which another door opened into a cellar dug deep into the hill.

Undoubtedly this had once been used as a frost-proof storeroom. A small ventilator pipe opened--so Nolan told Casey--in the middle of a greasewood clump. Nolan lighted a gasoline lantern that shed a white brilliance upon the room. On the long table which extended down one side of the room, Casey saw boxes of bottles and other supplies which he did not at the moment recognize.

"We'll have to rebottle all the whisky," said Nolan.

"You'll see a certain mark blown into the bottom of each one of these.

The champagne, I'm afraid, I must either confiscate and destroy or run the risk of marking the labels. The hop we'll lay aside for further consideration."
