“Pity the caverns—stopes!—have to be filled up with débris to prevent the mine caving in,” said Ora flippantly. “I went underground in Butte last week—to the eighteenth level of the Leonard. Nothing but endless streets and cross-alleys, all numbered——”

“And you didn’t find that interesting?” he asked indignantly. “To be a third of a mile below the surface of the earth and find it laid out like a city, with streets and rooms, and stations ten times as large as this, and lighted with electricity?”

“Yes, but the knowledge that you have a third of a mile of those streets and rooms—seventeen levels of them—on top of you, supported only by waste rock in the stopes, and timbers that are always snapping in two from the terrific pressure—timbermen working at every turn—‘Save YOURSELF’ the first thing you see when you leave that cage—Oh, well, I felt there was quite enough romance on top of the earth.”

“I am deeply disappointed in you. You told me once—why, even lately——”

“Oh, I haven’t changed the least little bit. Nothing in life,” and she looked at him with laughing eyes, “interests me as much at present as these two mines. But I am thankful that we are still within a reasonable distance of the surface. I am quite content to screw up my eyes and wander in fancy among the primary deposits close to the central fires. If I had a mine like yours, full of the beautiful copper ores instead of that hideous pyroxenite of mine, I should leave a glittering layer in every stope, support the roof with polished stone columns, light with hidden electric bulbs, and wander from one to the other imagining myself in Aladdin’s palace.”

“A fine practical miner you would make. It’s lucky that your mine is pyroxenite, not quartz. That is if you want to live in Europe.—Do you?”

“Of course. What have I in this part of the world? A mine cannot satisfy a woman for ever. I suppose you wouldn’t care if you never saw a woman again!”

“Oh!” He was looking hard at her.

“What else were you thinking of just now?” asked Ora, with that perverse desire to be superficial which so often possesses American women in decisive moments.

He sighed impatiently. “I’ve got a big job on my hands, one that will take me away from here more or less. Did Mark tell you of a land deal I put through?”
