"My God! how she rolls," said Guerin, going back to his place again. Of a sudden she began to quicken her pace, as though the train had parted. She might be slipping--he opened the sand lever. No, she was holding the rail, and then he knew that they had tipped over Zero Hill. He cut her back a notch, but allowed the throttle to remain wide open. Bennie saw the move and left the door ajar again. He knew where they were and wondered that Guerin did not ease off a bit, but he had been taught by Moran to fire and leave the rest to the engineer. Guerin glanced at his watch. He was one minute over-due at Zero Junction, a mile away. At the end of another minute he would have put that station behind him, less than two minutes late. He was making a record for himself. He was demonstrating that it is the daring young driver who has the sand to go up against the darkness as fast as wheels can whirl. He wished the snow was off the headlight. He knew the danger of slamming a train through stations without a ray of light to warn switchmen and others, but he could not bring himself to send the boy out to the front end in that storm the way she was rolling. And she did roll; and with each roll the bell tolled! tolled!! like a church bell tolling for the dead. The snow muffled the rail, and the cry of the whistle would not go twenty rods against that storm; and twenty rods, when you're making a mile and a half in a minute, gives barely time to cross yourself. About the time they tipped over the hill the night yard master came from the telegraph office, down at the junction, and twirled a white light at a switch engine that stood on a spur with her nose against an empty express car. "Back up," he shouted: "and kick that car in on the house track." "The Limited's due in a minute," said the switch engineer, turning the gauge lamp upon his watch.
