Wherefore Paw, Hank and Joe presently slipped into the habit of leaving Casey alone for an hour or so; being careful to keep the guns out of his reach, and returning to the dugout at unexpected intervals to make sure that all was well.

Casey Ryan knew his pots and pans, and how to make them fill his days if need be. With savory suppers and his care-free, Casey Ryan grin, he presently lulled them into accepting him as a handy man around camp, and into forgetting that he was at least a potential enemy. Afoot and alone in that unfriendly land, with his left hand smashed and carried in a sling, and on his tongue an Irish joke that implied content with his captivity, Casey Ryan would not have looked dangerous to more intelligent men than these three.

They should have looked one night under the bedding in Casey's bunk.

More important still would have been the safeguarding of their "giant powder" and caps and fuse. They should not have left it in a gouged, open hollow under a boulder near the dugout. They were not burdened by the weight of their brains, I imagine.

Just here I should like to say a few words to those who are wholly ignorant of the devastating power contained in "giant powder"--which is dynamite. If you have never had any experience with the stuff, you are likely to go out with a bang and a puff of bluish-brown smoke when you go. On the other hand, you may believe the weird tales one reads now and then, of how whole mountainsides have been thrown down by the discharge of a few sticks of dynamite. Or of one man striking terror to the very souls of a group of mutinous miners by threatening to throw a piece at them. Very well, now this is the truth without any frills of exaggeration or any belittlement:

Dynamite MAY go off by being thrown so that it lands with a jar, but it is not likely to be so hasty as all that. Whole boxes of it have been dropped off wagons traveling over rough trails, with no worse effect than a nervous chill down the spine of the driver of the wagon. It is true that old stuff, after lying around for months and months through varying degrees of temperature, may perform erratically, exploding when it shouldn't and refusing to explode when it should. The average miner refuses to take a chance with stale "giant" if he can get hold of fresh.

One stick the size of an ordinary candle, and from that to a maximum amount of four sticks, may be used to "load" a hole eighteen to twenty-four inches long, drilled into living rock. The amount of dynamite used depends upon the quality of rock to be broken and the skill and good judgment of the miner. In average hard-rock mining, from three to five of these holes are drilled in a s.p.a.ce four-by-six feet in area.

A stick of dynamite is exploded by inserting in one end of the stick a high-power detonating cap which will deliver a twenty-pound blow per X--whatever that means. From three- to six-X caps are used in ordinary mining. Three-X caps sometimes fail to explode a stick of dynamite. A six-X cap, delivering a one-hundred-and-twenty-pound blow, may be counted upon to do the work without fail.

The cap itself is exploded by a spark running through a length of fuse, the length depending altogether upon the time required to reach a point of safety after the fuse is lighted. The cap is really more dangerous to handle than is the dynamite itself. The cap is a tricky thing that may go off at any jar or scratch or at a spark from pipe or cigarette.

You can, if you are sufficiently careless of possible results, light the twisted paper end of a stick of dynamite and watch the dynamite burn like wax in your fingers; it MAY go off and set your friends to work retrieving portions of your body. More likely, it will do nothing but burn harmlessly.

Well, then, a piece of fuse is inserted in the open end of the cap, and the metal pressed tight against the fuse to hold it in place. Pressed down by the miner's teeth, sometimes, if he has been long in the business and has grown careless about his head; otherwise he crimps the cap on with a small pair of pliers or the back of his knife blade--and feels a bit easier when it is done without losing a hand.

You would think, unless you are accustomed to the stuff, that when five holes are loaded with, probably, ten or twelve sticks of dynamite to the lot, each hole containing a six-X exploding cap as well, that the first shot would likewise be the last shot and that the whole tunnel would cave in and the mountain behind it would shake. Nothing like that occurs. If there are five loaded holes in the tunnel face, and you do not hear, one after the other, five m.u.f.fled BOOMS, you will know that one hole failed to go off--and that the miner is worried. It happens sometimes that four holes loaded with eight sticks of dynamite explode within a foot or so of the fifth hole and yet the fifth hole remains "dead" and a menace to the miner until it is discharged.

So please don't swallow those wild tales of a stick of dynamite that threw down a mountainside. I once read a story--it was not so long ago--of a Chinaman who wiped out a mine with a little piece of dynamite which he carried in his pocket. I laughed.

Casey Ryan, on the first day when he was left alone with his crippled hand and his pots and pans for company, did nothing whatever that he would not have done had one of the three been present. He was suspicious of their going and thought it was a trap set to catch him in an attempted escape.

On the second day when the three went off together and left him alone, Casey went out gathering wood and discovered just where the "powder,"

fuse and caps were kept under a huge, black boulder between the tunnel portal and the dugout. On the third day he also gathered wood and helped himself to two sticks of dynamite, three caps and eighteen inches of fuse. Not enough to be missed unless they checked their supply more carefully than Casey believed they did; but enough for Casey's purpose nevertheless.

That night, while the moon shone in through the dingy window at the head of his bunk and gave him a little light to work by, Casey sat up in bed and snored softly and with a soothing rhythm while he cut a stick of dynamite in two, capped five inches of fuse for each piece working awkwardly with his one good hand and pinching the caps tight with his teeth, which might have sent him with a bang into Kingdom Come--and very carefully worked the caps into the powder until no more than three inches of fuse protruded from the end of the half stick. It would have been less dangerous to land with a yell in the middle of the floor and fight the three men with one bare hand, but Casey's courage never turned a hair.

Still snoring mildly, he held up to the moonlight two deadly weapons and surveyed them with much satisfaction. They would not be so quick, as fiction would have them, but if his aim was accurate in throwing, they would be deadly enough. Moreover, he could count with a good deal of certainty upon a certain degree of terror which the sight of them in his hand would produce.

When Casey Ryan cooked breakfast next morning, he carried two half-sticks of loaded dynamite under his hand in the sling. Can you wonder that even he shied at standing over the stove cooking hot cakes and complained that his broken hand pained him a lot and that the heat made it worse? But a shrewd observer would have noticed on his face the expression of a cat that has been shut in the pantry over night.

Joe volunteered to take another look at the hand and see if blood poison was "setting in"; but Casey said it didn't feel like blood poison. He had knocked it against the bunk edge in his sleep, he declared. He'd dose 'er with iodine after a while, and she'd be all right.

Joe let it go at that, being preoccupied with other matters at which Casey could only guess. He conferred with Paw outside the dugout after breakfast, called Hank away from the dish-washing and the three set off toward the tunnel with a brisker air than usually accompanied them to work. Casey watched them go and felt reasonably sure of at least two hours to himself.

The first thing Casey did after he had made sure that he was actually alone was to remove the deadly stuff from the sling and lay it on a shadowed shelf where it would be safe but convenient to his hand. Then, going to his bunk, he reached under the blankets and found the other stick of dynamite which he had not yet loaded. This he laid on the kitchen table and cut it in two as he had done last night with the other stick. With his remaining cap he loaded a half and carried it back to his bunk. He was debating in his mind whether it was worth while purloining another cap from a box under the boulder when another fancy took him and set him grinning.

Four separate charges of dynamite, he reasoned, would not be necessary.

It was an even chance that the sight of a piece with the fuse in his hand would be sufficient to tame Paw or Hank or Joe--or the three together, for that matter--without going further than to give them a sight of it.

With that idea uppermost, Casey split the paper carefully down the side of the remaining half-stick, took out the contents in a tin plate and carried it outside where he buried it in the sand beneath a bush.

Returning to the dugout he made a thick dough of leftover pancake batter and molded it into the dynamite wrapping with a fragment of harmless fuse protruding from the opened end. When the thing was dry, Casey thought it would look very deadly and might be useful. After several days of helplessness for want of a weapon, Casey was in a mood to supply himself generously.

He finished the dish-washing, working awkwardly with one hand. After that he put a kettle of beans on to boil, filled the stove with pinon sticks and closed the drafts. He armed himself with the two loaded pieces of dynamite from the cupboard, filled his pockets with such other things as he thought he might need, and went prospecting on his own account.

At the portal of the tunnel he stopped and listened for the ping-g, ping-g of a single-jack striking steadily upon steel. But the tunnel was silent, the ore car uptilted at the end of its track on the dump.

Yet the three men were supposedly at work in the mine, had talked at breakfast about wanting to show a certain footage when the boss returned, and of needing to hurry.

Casey went into the tunnel, listening and going silently; sounds travel far in underground workings. At the mouth of the first right-hand drift he stopped again and listened. This, if he would believe Joe, was the drift where the bad ground had caused the accident to Joe and his partner whose leg had been broken. Casey found the drift as silent as the main tunnel. He went in ten feet or so and lighted the candle he had pulled from inside his shirt. With the candle held in the swollen fingers of his injured hand, and a prospector's pick taken from the portal in his other, Casey went on cautiously, keeping an eye upon the roof which, to his wise, squinting eyes, looked perfectly solid and safe.

If a track had ever been laid in this drift it had long since been removed. But a well-defined path led along its center with boot tracks going and coming, blurring one another with much pa.s.sing. Casey grinned and went on, his ears c.o.c.ked for any sound before or behind, his shoes slung over his arm by their tied laces.

So he came, in the course of a hundred feet or so, to a crude door of split cedar slabs, the fastening padlocked on his side. Casey had vaguely expected some such bar to his path, and he merely gave a grunt of satisfaction that the lock was old and on his side of the door.

With his jackknife Casey speedily took off one side of the lock and opened it. Making the door appear locked behind him when he had pa.s.sed through was a different matter, and Casey did not attempt it. Instead, he merely closed the door behind him, carrying the padlock in with him.

As Casey reviewed his situation, being on the b.u.t.te at all was a risk in itself. One detail more or less could not matter so much. Besides, he was a bold Casey Ryan with two loaded half-sticks of dynamite in his sling.

A crude ladder against the wall of a roomy stope beyond the door did not in the least surprise him. He had expected something of this sort.

When he had topped the ladder and found himself in a chamber that stretched away into blackness, he grunted again his mental confirmation of a theory working out beautifully in fact. His candle held close to the wall, he moved forward along the well-trodden path, looking for a door. Mechanically he noticed also the formation of the wall and the vein of ore--probably high-grade in pockets, at least--that had caused this chamber to be dug. The ore, he judged, had long since been taken out and down through the stope into the tunnel and so out through the main portal. These workings were old and for mining purposes abandoned.

But just now Casey was absorbed in solving the one angle of the mystery which he had stumbled upon at first, and he gave no more than a glance and a thought to the silent testimony of the rock walls.

He found the door, fastened also on the outside just as he had expected it would be. Beside it stood a rather clever heating apparatus which Casey did not examine in detail. His Irish heart was beating rather fast while he unfastened the door. Beyond that door his thoughts went questing eagerly but he hesitated nevertheless before he lifted his knuckles and rapped.

There was no reply. Casey waited a minute, knocked again, then pulled the door open a crack and looked in. The old woman sat there rocking back and forth, steadily, quietly. But her thin fingers were rolling a corner of her ap.r.o.n hem painstakingly, as if she meant to hem it again.

Her eyes were fixed absently upon the futile task. Casey watched her as long as he dared and cleared his throat twice in the hope that she would notice him. But the old woman rocked back and forth and rolled her ap.r.o.n hem; unrolled it and carefully rolled it again.

"Good morning, ma'am," said Casey, clearing his throat for the third time and coming a step into the room with his candle dripping wax on the floor.

For just an instant the uneasy fingers paused in their rolling of the ap.r.o.n hem. For just so long the rockers hesitated in their motion.

But the old woman did not reply nor turn her face toward him; and Casey pushed the door shut behind him and took two more steps toward her.

"I come to see if yuh needed anything, ma'am; a friend, mebbe." Casey grinned amiably, wanting to rea.s.sure her if it were possible to make her aware of his presence. "They had yuh locked in, ma'am. That don't look good to Casey Ryan. If yuh wanta get out--if they got yuh held a prisoner here, or anything like 'that, you can trust Casey Ryan any old time. Is--can I do anything for yuh, ma'am?" The old woman dropped her hands to her lap and held them there, closely clasped. Her head swung slowly round until she was looking at Casey with that awful, fixed stare she had heretofore directed at the wall or the floor.

"Tell those h.e.l.l-hounds they have a thousand years to burn--every one of them!" she said in a deep, low voice that had in it a singing resonance like a chant. "Every cat, every rat, every mouse, every louse, has a thousand year's to burn. Tell Mart the hounds of h.e.l.l must burn!" Her voice carried a terrible condemnation far beyond the meaning of the words themselves. It was as if she were p.r.o.nouncing the doom of the whole world. "Every cat, every rat, every mouse, every louse--"

Casey Ryan's jaw dropped an inch. He backed until he was against the door. He had to swallow twice before he could find his voice, and those of you who know Casey Ryan will appreciate that. He waited until she had finished her declaration.

"No, ma'am, you're wrong. I come up here to see if I could help yuh."

"Hounds of h.e.l.l--black as the bottomless pit that spewed you forth to prey upon mankind! The world will have to burn. Tell those hounds of h.e.l.l that bay at the gibbous moon the world will have to burn. Every cat, every rat, every mouse, every louse has a thousand years to burn!"

Casey Ryan, with his mouth half open and his eyes rather wild, furtively opened the door behind him. Still meeting fixedly the dull glare of the old woman's eyes, Casey slid out through the door and fastened it hastily behind him. With an uneasy glance now and then over his shoulder as if he feared the old woman might be in pursuit of him, he hurried back down the ladder to the closed door in the drift, pulled the door shut behind him and put the padlock in place before he breathed naturally.

He stopped then to put on his shoes, made his way to the drift opening and listened again for voices or footsteps. When he found the way clear he hurried out and back to the dugout. The first thing he did was to fill his pipe and light it. Even then the sonorous voice of the old woman intoning her dreadful proclamation against the world rang in his ears and sent occasional ripples of horror down his spine. Seen through the window, she had looked a sad, lonely old lady who needed sympathy and help. At closer range she was terrible. Casey was trying to forget her by busying himself about the stove when Joe walked in unexpectedly.

Joe stood just inside the door, staring at Casey with a gla.s.sy look in his eyes. Something in Joe's face warned Casey of impending events; but with that terrible old woman still fresh in his mind, Casey was in the mood to welcome distraction of any sort. He shifted his hand in the sling so that his concealed weapons lay more comfortably therein, secure from detection, and waited.

Joe leaned forward, lifted an arm slowly and aimed a finger at Casey accusingly.

"Pap says that you're a Federal officer!" he began, waggling his finger at Casey. "Pap thinks you come here spyin' around t' see what we're up to on this here b.u.t.te. Now, you can't pull nothin' like that! You can't get away with it.

"Hank, he wants t' b.u.mp yuh off an' say nothin' to anybody. Now, I come t' have it out with yuh. If you're a Federal officer we're goin'

t' settle with yuh an' take no chances. Mart, he's more easy-goin' in some ways, on account of havin' his crazy ol' mother on 'is hands t'

take care of. Mart don't want no killin'--on account of his mother goin' loony when 'is dad got killed. But Mart ain't here. Pap an'
