and blowing steam, with polished headlight and new flags fluttering at her shoulders, glided backward, like a gay girl on roller skates, to take her place. She had a helper up the hill, one of those heavy-mounted climbers, and when they came to the steep grade, and the powerful mogul with steady step marked perfect time, the Rockaway chafed and fretted like a spoiled colt. At every curve her feet would fly from under her, and her wheels go round so fast that it seemed she would strip herself; and when the driver shut off and dropped sand to allow her to get her footing again, she blew off steam and wasted the water which is so precious on a heavy grade. Between stations she would foam and throw water out of her stack, and when shut off show dry blue steam in her gauges; so when they stopped the driver had to hold her on the centre, with her valves closed and throttle wide open, for that keeps the boiler strained and holds the water up over the flues and crown sheet. In good time the mogul dragged her and her train to the top, 10,050 feet above the sea, and left her to fall down the western slope.
