As soon as they left the span roofing of the station, they were in the snow. The wind, blowing from the east, caught the locomotive in front, beating against it in violent gusts. The two men in the cab did not suffer much at first, clothed as they were in thick woollen garments, with their eyes protected by spectacles. But the light on the engine, usually so brilliant at night, seemed swallowed up in the thick fall of snow. Instead of the metal way being illuminated three or four hundred yards ahead, it came into evidence in a sort of milky fog. The various objects could only be distinguished when the locomotive was quite close to them, and then they appeared indistinct, as in a dream. The anxiety of the driver was complete when he recognised, on reaching the first signal-post, that he would certainly be unable, as he had feared, to see the red lights barring the lines at the regulation distances. From that moment he advanced with extreme prudence, but without it being possible for him to slacken speed, for the wind offered extraordinary resistance, and delay would have been as dangerous as a too rapid advance. As far as Harfleur, La Lison went along at a good and well-sustained pace. The layer of snow that had fallen did not as yet trouble Jacques, for, at the most, there were two feet on the line, and the snow-blade could easily clear away four. All his anxiety was to maintain the speed, well aware that the real merit of a driver, after temperance, and esteem for his engine, consisted in advancing in an uniform way, without jolting, and at the highest pressure possible. Indeed, his only defect lay in his obstinacy not to stop. He disobeyed the signals, always thinking he would have time to master La Lison; and so he now and again over-shot the mark, crushing the crackers, the "corns" as they are termed, and, on two occasions, this habit had caused him to be suspended for a week. But now, in the great danger in which he felt himself, the thought that Séverine was there, that he was entrusted with her dear life, increased his strength of character tenfold; and he maintained his determination to be cautious all the way to Paris, all along that double metal line, bristling with obstacles that he must overcome.
