five o'clock
The gray light become intermingled with red , and soon the sky to the east was aflame . Paul let down the carriage window , and long waves of sweet mountain air , laden with the smell of peat , flowed in upon him . His lips parted and his breast expanded . At five o'clock the engine was attached . A few carriages were added at the platform , and these contained a number of pitmen , in their red-stained fustian , going down for the morning shift . When the train moved westward , the sun had risen , and all the air was musical with the songs of the birds . Very soon the train ran in among the mountains , and then at last the bitterness of Paul Ritson 's heart seemed to fall away from him like a garment .
