And he, who was usually so lenient for the vices of this drunkard, kicked him until he awoke, and was on his feet. Pecqueux, benumbed with cold, grumbled as he grasped the shovel:
"That'll do, that'll do; I'm going there!"
With the fire made up, the pressure rose; and it was time, for La Lison had just entered a cutting where it had to cleave through four feet of snow. It advanced with an energetic effort, vibrating in every part. For an instant it showed signs of exhaustion, and seemed as if about to stand still, like a vessel that has touched a sandbank. What increased the weight it had to draw was the snow, which had accumulated in a heavy layer on the roofs of the carriages.
They continued thus, seaming the whiteness with a dark line, with this white sheet spread over them; while the engine itself had only borders of ermine draping its sombre sides, where the snowflakes melted to run off in rain. Once more it extricated itself, notwithstanding the weight, and passed on. At the top of an embankment, that made a great curve, the train could still be seen advancing without difficulty, like a strip of shadow lost in some fairyland sparkling with whiteness.
But, farther on, the cuttings began again; and Jacques and Pecqueux, who had felt La Lison touch, stiffened themselves against the cold, erect at their posts, which even, were they dying, they could not desert. Once more the engine lost speed; it had got between two talus, and the stoppage came slowly and without a shock. It seemed as if glued there, exhausted; as though all its wheels were clogged, tighter and tighter. It ceased moving, the end had come; the snow held the engine powerless.
"It's all up!" growled Jacques with an oath.
He remained a few seconds longer at his post, his hand on the wheel, opening everything to see if the obstacle would yield. Then, hearing La Lison spitting and snorting in vain, he shut the regulator, and, in his fury, swore worse than ever.
The headguard leant out from the door of his van, and Pecqueux, turning round, shouted to him:
"It's all up! We're stuck!"
Briskly the guard sprang into the snow, which reached to his knees. He approached, and the three men consulted together.
