On Sunday Étienne escaped from the settlement at nightfall. A very clear sky, sprinkled with stars, lit up the earth with the blue haze of twilight. He went down towards the canal, and followed the bank slowly, in the direction of Marchiennes. It was his favourite walk, a grass-covered path two leagues long, passing straight beside this geometrical water-way, which unrolled itself like an endless ingot of molten silver. He never met any one there. But on this day he was vexed to see a man come up to him. Beneath the pale starlight, the two solitary walkers only recognized each other when they were face to face.

      "What! is it you?" said Étienne.

      Souvarine nodded his head without replying. For a moment they remained motionless, then side by side they set out towards Marchiennes. Each of them seemed to be continuing his own reflections, as though they were far away from each other.

      "Have you seen in the paper about Pluchart's success at Paris?" asked Étienne, at length. "After that meeting at Belleville, they waited for him on the pavement, and gave him an ovation. Oh! he's afloat now, in spite of his sore throat. He can do what he likes in the future."

      The engine-man shrugged his shoulders. He felt contempt for fine talkers, fellows who go into politics as one goes to the bar, to get an income out of phrases.

      Étienne was now studying Darwin. He had read fragments, summarized and popularized in a five-sou volume; and out of this ill-understood reading he had gained for himself a revolutionary idea of the struggle for existence, the lean eating the fat, the strong people devouring the pallid middle class. But Souvarine furiously attacked the stupidity of the Socialists who accept Darwin, that apostle of scientific inequality, whose famous selection was only good for aristocratic philosophers. His mate persisted, however, wishing to reason out the matter, and expressing his doubts by an hypothesis: supposing the old society were no longer to exist, swept away to the crumbs; well, was it not to be feared that the new world would grow up again, slowly spoilt by the same injustices, some sick and others flourishing, some more skilful and intelligent, fattening on everything, and others imbecile and lazy, becoming slaves again? But before this vision of eternal wretchedness, the engine-man shouted out fiercely that if justice was not possible with man, then man must disappear. For every rotten society there must be a massacre, until the last creature was exterminated. And there was silence again.

      For a long time, with sunken head, Souvarine walked over the short grass, so absorbed that he kept to the extreme edge, by the water, with the quiet certainty of a sleep-walker on a roof. Then he shuddered causelessly, as though he had stumbled against a shadow. His eyes lifted and his face was very pale; he said softly to his companion:

      "Did I ever tell you how she died?"

      "Whom do you mean?"

      "My wife, over there, in Russia."

      Étienne made a vague gesture, astonished at the tremor in his voice and at the sudden desire for confidence in this lad, who was usually so impassive in his stoical detachment from others and from himself. He only knew that the woman was his mistress, and that she had been hanged at Moscow.

      "The affair hadn't gone off," Souvarine said, with eyes still vacantly following the white stream of the canal between the bluish colonnades of tall trees. "We had been a fortnight at the bottom of a hole undermining the railway, and it was not the imperial train that was blown up, it was a passenger train. Then they arrested Annutchka. She brought us bread every evening, disguised as a peasant woman. She lit the fuse, too, because a man might have attracted attention. I followed the trial, hidden in the crowd, for six days."

      His voice became thick, and he coughed as though he were choking.

      "Twice I wanted to cry out, and to rush over the people's heads to join her. But what was the good? One man less would be one soldier less; and I could see that she was telling me not to come, when her large eyes met mine."

      He coughed again.

      "On the last day in the square I was there. It was raining; they stupidly lost their heads, put out by the falling rain. It took twenty minutes to hang the other four; the cord broke, they could not finish the fourth. Annutchka was standing up waiting. She could not see me, she was looking for me in the crowd. I got on to a post and she saw me, and our eyes never turned from each other. When she was dead she was still looking at me. I waved my hat; I came away."

      There was silence again. The white road of the canal unrolled to the far distance, and they both walked with the same quiet step as though each had fallen back into his isolation. At the horizon, the pale water seemed to open the sky with a little hole of light.

      "It was our punishment," Souvarine went on roughly. "We were guilty to love each other. Yes, it is well that she is dead; heroes will be born from her blood, and I no longer have any cowardice at my heart. Ah! nothing, neither parents, nor wife, nor friend! Nothing to make my hand tremble on the day when I must take others' lives or give up my own."

      Étienne had stopped, shuddering in the cool night. He discussed no more, he simply said:

      "We have gone far; shall we go back?"

      They went back towards the Voreux slowly, and he added, after a few paces:

      "Have you seen the new placards?"

      The Company had that morning put up some more large yellow posters. They were clearer and more conciliatory, and the Company undertook to take back the certificates of those miners who went down on the following day. Everything would be forgotten, and pardon was offered even to those who were most implicated.

      "Yes, I've seen," replied the engine-man.

      "Well, what do you think of it?"

      "I think that it's all up. The flock will go down again. You are all too cowardly."

      Étienne feverishly excused his mates: a man may be brave, a mob which is dying of hunger has no strength. Step by step they were returning to the Voreux; and before the black mass of the pit he continued swearing that he, at least, would never go down; but he could forgive those who did. Then, as the rumour ran that the carpenters had not had time to repair the tubbing, he asked for information. Was it true? Had the weight of the soil against the timber which formed the internal skirt of scaffolding to the shaft so pushed it in that the winding-cages rubbed as they went down for a length of over fifty metres?

      Souvarine, who once more became uncommunicative, replied briefly. He had been working the day before, and the cage did, in fact, jar; the engine-men had even had to double the speed to pass that spot. But all the bosses received any observations with the same irritating remark: it was coal they wanted; that could be repaired later on.

      "You see that will smash up!" Étienne murmured. "It will be a fine time!"

      With eyes vaguely fixed on the pit in the shadow, Souvarine quietly concluded:

      "If it does smash up, the mates will know it, since you advise them to go down again."

      Nine o'clock struck at the Montsou steeple; and his companion having said that he was going to bed, he added, without putting out his hand:

      "Well,
