Barren Ground by Ellen Glasgow

Far over the autumn fields, she heard the whistle of the train as it rounded the long curve at the station. Before the sound had floated past her she had come to one of those impetuous decisions which were characteristic of her temperament. "I'll go away in the morning," she resolved. "I'll go on the first train, the one that whistles at sunrise. If I take that, I can leave the house before light."

Immediately afterwards, as soon as the idea had taken possession of her, she felt the renewal of courage in her thoughts. Once that was settled, she told herself, and there was no turning back, everything would be easier. Just to go away somewhere. It made no difference where the train went. She would go to the very end, the farther the better, as long as her money held out. "I can scrape together almost seventy dollars," she thought. "Besides the fifty I made at the store, I've saved the twenty dollars Nathan and Rose Emily gave me for a wedding present. That much ought to take me somewhere and keep me until I can find something to do. " Her father, she realized with a pang, would have to manage without her. Perhaps he would be obliged to mortgage the place again. She hoped he wouldn't have to sell Dan and Beersheba, and she was confident in her heart that he would never do this. He would sooner part with the roof over his head.
