The Trail of the White Mule

by B. M. Bower

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 passing. Casey grinned and went on, his ears cocked 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 passed 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 butte 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 apron 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 apron hem; unrolled it and carefully rolled it again.
