At four o’clock the eastern party and their guides were due to meet in the hoisting works for their excursion down the mine. It was nearly a half-hour later, however, when the two ladies, who made up the feminine portion of the party, slunk out of the spacious dressing-rooms, giggling and blushing in their male attire. Jerry, Marsden the foreman, and one of the shift bosses, were lounging about the mouth of the shaft waiting for them. There were greetings and laughter, the women hugging themselves close in the long overcoats they wore against the chill of the downward passage, and pulling over their hair the shapeless cloth caps they had been given for head-gear.

Through the wide opening that led to the dumps the figure of Black Dan, dark against the brilliance of the afternoon, could be seen walking on the car tracks with the rest of the party. In the muddy overalls, long boots and soft felt hat which was the regulation underground dress of the men, he presented the appearance of some black-browed, heavily bearded pirate in the garb of a tramp. As the cage slid up to the shaft mouth, he entered the building, gave the embarrassed women an encouraging nod, and selected a lantern from a collection of them standing in a corner.

With little cries of apprehension the women stepped on the flat square of flooring, their three escorts ranged closely round them, the signal to descend, was given, and the cage dropped quickly out of sight into the steaming depths. Black Dan, Barney Sullivan and the strangers were to descend on the cage in the next compartment, and while they waited for it to come up, stood talking of the formations of the mineral, how it had been found and of the varying richness of the ore-bodies. Suddenly Black Dan thought of his specimen, which had come from a part of the mine they were to visit first, and turning went into the men’s dressing-room, where he had left it in his coat pocket.

His clothes had been hung on the last of a line of pegs along the wall. To this he went, and, ignorant of the fact that Jerry had undressed after him, thrust his hand into the pocket of what he thought was his own coat. Instead of the stone his fingers encountered a letter. He drew it out and saw that it was the one he had seen handed to his son-in-law a few hours before.

At once he drew the paper from the envelope. No qualm of conscience deterred him; instead he experienced a sense of satisfaction that his uncertainty should be thus simply brought to an end. His eye traveled over the few lines, instantly grasping their meaning. He knew the signature. Jerry was not intriguing with a common woman of the town; he was deserting his wife with a girl, hitherto of unspotted reputation, and for years beloved by Rion. It meant ruin and misery for the two human beings nearest to the bonanza king’s heart.

For a moment he stood motionless, the letter in his hand, and before his eyes he saw red. Then it cleared away. He put the paper back in its envelope and thrust it in his pocket. When he came out into the shaft house Barney Sullivan noticed that his face was reddened and that the whites of his eyes were slightly bloodshot. One of the strangers rallied him on his absence, which had been of some minutes’ duration, and he made no answer, simply motioning them to get on the cage with an imperious movement of his head.

The shaft of the Cresta Plata was over two thousand feet in depth, and the heat of the lower levels was terrific. Here the miners, naked, save for a cap, breechclout, and canvas shoes, worked twenty-minute shifts, unable to stand the fiery atmosphere for longer. Cold air was pumped down to them from the surface, the pipes that carried it following the roofs of the long, dark tunnels, their mouths blowing life-giving coolness into stopes where the men could not touch their metal candlesticks, and the iron of the picks grew hot. There were places where the drops that fell from the roof raised blisters on the backs they touched. On most of these lower levels there was much water, its temperature sometimes boiling. The miners of the Cresta Plata had a saying that no man had ever fallen into water that reached to his hips and lived. At the bottom of the shaft—the “sump” in mining parlance—was a well of varying depths which perpetually exhaled a scalding steam.

Black Dan took his guests to the fifteen-hundred-foot level, whence the greatest riches of the mine had been taken. He was more than usually silent as they walked from tunnel to tunnel and drift to drift. Barney Sullivan was the cicerone of the party, explaining the formation, talking learnedly of the dip of the vein, holding up his lantern to let its gleam fall on the dark bluish “breast” into which the miners drove their picks with a gasp of expelled breath. Nearly an hour had passed when Black Dan, suddenly drawing him back, whispered to him that he was going up to the eight-hundred-foot level to see Jerry, to whom he wished to give some instructions about the dinner that evening. Barney, nodding his comprehension, moved on with the guests, and Black Dan walked back to the station.

As he went up in the cage he passed level after level, like the floors of a great underground building. Yellow lights gleamed through the darkness on the circular forms of west timbers, hollowed caves trickling with moisture, car tracks running into blackness. Each floor was peopled with wild, naked shapes, delving ferociously in this torrid inferno. At the eight-hundred-foot level he got off, the bell rang, and the empty cage went sliding up. The landing on to which he stepped was deserted, and he walked up one of the tunnels that branched from it, called to a pick-boy, whom he saw in the distance, that he wanted Mr. Barclay found and sent to him at once. The figure of the boy scudded away into the darkness, and Black Dan went back to the landing.

It was an open space, a small, subterranean room, the lanterns fastened on its walls gilding with their luster the pools of water on the muddy floor. There were boxes used for seats standing about, and on pegs in the timbers the miners’ coats hung. Where the shaft passed down there were several square openings—larger than ordinary doorways, iron-framed and with plates of iron set into the moist ground—which gave egress to the cages. Now there was only a black void there, the long shaft stretching hundreds of feet upward and downward.
