Just at that moment, Jacques, in exasperation, repeated:
"It'll never reach the top, unless it's greased!"
And he did what he had not done thrice in his life. He took the oil-can to grease the engine as it went along. Climbing over the rail, he got on the frame-plate beside the boiler, which he followed to the end. It was a most perilous undertaking. His feet slipped on the narrow strip of iron, wet with snow. He was blinded, and the terrible wind threatened to sweep him away like a straw.
La Lison, with this man clinging to its side, continued its panting course in the darkness, cutting for itself a deep trench in the immense white sheet covering the ground. The engine shook him, but bore him along. On attaining the cross-piece in front, he held on to the rail with one hand, and, stooping down before the oil-box of the cylinder on the right, experienced the greatest difficulty in filling it. Then he had to go round to the other side, like a crawling insect, to grease the cylinder on the left. And when he got back to his post, he was exhausted and deadly pale, having felt himself face to face with death.
"Vile brute!" he murmured.
Pecqueux had recovered, in a measure, from his drowsiness, and pulled himself together. He, too, was at his post, watching the line on the left. On ordinary occasions he had good eyes, better than those of his chief, but in this storm everything had disappeared. They, to whom each mile of the metal way was so familiar, could barely recognise the places they passed. The line had disappeared in the snow, the hedges, the houses, even, seemed about to follow suit. Around them was naught but a deserted and boundless expanse, where La Lison seemed to be careering at will, in a fit of madness.
Never had these two men felt so keenly the fraternal bond uniting them as on this advancing engine, let loose amidst all kinds of danger, where they were more alone, more abandoned by the world, than if locked up in a room by themselves; and where, moreover, they had the grievous, the crushing responsibility of the human lives they were dragging after them.
The snow continued falling thicker than ever. They were still ascending, when the fireman, in his turn, fancied he perceived the glint of a red light in the distance and told his chief. But already he had lost it. His eyes must have been dreaming, as he sometimes said. And the driver, who had seen nothing, remained with a beating heart, troubled at this hallucination of another, and losing confidence in himself.
What he imagined he distinguished beyond the myriads of pale flakes were immense black forms, enormous masses, like gigantic pieces of the night, which seemed to displace themselves and come before the engine. Could these be landslips, mountains barring the line against which the train was about to crush? Then, affrighted, he pulled the rod of the whistle, and whistled long, despairingly; and this lamentation went slowly and lugubriously through the storm. Then he was astonished to find that he had whistled at the right moment, for the train was passing the station of Saint-Romain at express speed, and he had thought it two miles away.
