Perch of the Devil by Gertrude Atherton — Read

The Primo vein had been recovered some time since and Ora had traversed the fault drift twice and watched the drilling from the station; not only to assert her rights as mistress of the mine but to experience the sensations she had anticipated. She soon discovered that when a woman is in love, and the issue doubtful, other interests fail to provide sensations. But she went down into the mine every day and roamed through the older workings. She was tormented and restless, but by no means without hope; and this being the case she sometimes wondered why she continued to write to Valdobia as if nothing had occurred to interfere with their tacit engagement. It was her duty to tell him the truth, at once, but she switched off all other currents every Saturday morning and wrote her Roman long gay tantalising letters; being gifted as a scribe, like so many women, she made them notable with amusing and enlightening incidents of mining-camp life.

She had not seen Gregory since Monday evening. He had gone suddenly to Butte on the morning following the visit of the geologists, and had telephoned her that he should take the afternoon train to the Capital and no doubt be detained for several days. She had expected that he would telephone or telegraph from Helena; that he would write was too much to expect; she had never seen his handwriting. But he had not recognised her existence.
