As soon as the story was spread at Montsou, a new crowd arrived. Nothing was to be seen; but they remained there all the same, and had to be kept at a distance. Down below, the work went on day and night. For fear of meeting an obstacle, the engineer had had three descending galleries opened in the seam, converging to the point where the enclosed miners were supposed to be. Only one pikeman could hew at the coal on the narrow face of the tube; he was relieved every two hours, and the coal piled in baskets was passed up, from hand to hand, by a chain of men, increased as the hole was hollowed out. The work at first proceeded very quickly; they did six metres a day.
Zacharie had secured a place among the workers chosen for the hewing. It was a post of honour which was disputed over, and he became furious when they wished to relieve him after his regulation two hours of labour. He robbed his mates of their turn, and refused to let go the pick. His gallery was soon in advance of the others. He fought against the coal so fiercely that his breath could be heard coming from the tube like the roar of a forge within his breast. When he came out, black and muddy, dizzy with fatigue, he fell to the ground and had to be wrapped up in a covering. Then, still tottering, he plunged back again, and the struggle began anew—the low, deep blows, the stifled groans, the victorious fury of massacre. The worst was that the coal now became hard; he twice broke his tool, and was exasperated that he could not get on so fast. He suffered also from the heat, which increased with every metre of advance, and was unbearable at the end of this narrow hole where the air could not circulate. A hand ventilator worked well, but aeration was so inadequate that on three occasions it was necessary to take out fainting hewers who were being asphyxiated.
Négrel lived below with his men. His meals were sent down to him, and he sometimes slept for a couple of hours on a truss of straw, rolled in a cloak. The one thing that kept them up was the supplication of the wretches beyond, the call which was sounded ever more distinctly to hasten on the rescue. It now rang very clearly with a musical sonority, as though struck on the plates of a harmonica. It led them on; they advanced to this crystalline sound as men advance to the sound of cannon in battle. Every time that a pikeman was relieved, Négrel went down and struck, then applied his ear; and every time, so far, the reply had come, rapid and urgent. He had no doubt remaining; they were advancing in the right direction, but with what fatal slowness! They would never arrive soon enough. On the first two days they had indeed hewn through thirteen metres; but on the third day they fell to five, and then on the fourth to three. The coal was becoming closer and harder, to such an extent that they now with difficulty struck through two metres. On the ninth day, after superhuman efforts, they had advanced thirty-two metres, and calculated that some twenty must still be left before them. For the prisoners it was the beginning of the twelfth day; twelve times over had they passed twenty-four hours without bread, without fire, in that icy darkness! This awful idea moistened the eyelids and stiffened the arm of the workers. It seemed impossible that Christians could live longer. The distant blows had become weaker since the previous day, and every moment they trembled lest they should stop.
Maheude came regularly every morning to sit at the mouth of the shaft. In her arms she brought Estelle, who could not remain alone from morning to night. Hour by hour she followed the workers, sharing their hopes and fears. There was feverish expectation among the groups standing around, and even as far as Montsou, with endless discussion. Every heart in the district was beating down there beneath the earth.
On the ninth day, at the breakfast hour, no reply came from Zacharie when he was called for the relay. He was like a madman, working on furiously with oaths. Négrel, who had come up for a moment, was not there to make him obey, and only a captain and three miners were below. No doubt Zacharie, infuriated with the feeble vacillating light, which delayed his work, committed the imprudence of opening his lamp, although severe orders had been given, for leakages of fire-damp had taken place, and the gas remained in enormous masses in these narrow, unventilated passages. Suddenly, a roar of thunder was heard, and a spout of fire darted out of the tube as from the mouth of a cannon charged with grapeshot. Everything flamed up and the air caught fire like powder, from one end of the galleries to the other. This torrent of flame carried away the captain and three workers, ascended the pit, and leapt up to the daylight in an eruption which split the rocks and the ruins around. The inquisitive fled, and Maheude arose, pressing the frightened Estelle to her breast.
When Négrel and the men came back they were seized by a terrible rage. They struck their heels on the earth as on a stepmother who was killing her children at random in the imbecile whims of her cruelty. They were devoting themselves, they were coming to the help of their mates, and still they must lose some of their men! After three long hours of effort and danger they reached the galleries once more, and the melancholy ascent of the victims took place. Neither the captain nor the workers were dead, but they were covered by awful wounds which gave out an odour of grilled flesh; they had drunk of fire, the burns had got into their throats, and they constantly moaned and prayed to be finished off. One of the three miners was the man who had smashed the pump at Gaston-Marie with a final blow of the shovel during the strike; the two others still had scars on their hands, and grazed, torn fingers from the energy with which they had thrown bricks at the soldiers. The pale and shuddering crowd took off their hats when they were carried by.
Maheude stood waiting. Zacharie's body at last appeared. The clothes were burnt, the body was nothing but black charcoal, calcined and unrecognizable. The head had been smashed by the explosion and no longer existed. And when these awful remains were placed on a stretcher, Maheude followed them mechanically, her burning eyelids without a tear. With Estelle drowsily lying in her arms, she went along, a tragic figure, her hair lashed by the wind. At the settlement Philoméne seemed stupid; her eyes were turned into fountains and she was quickly relieved. But the mother had already returned with the same step to Réquillart; she had accompanied her son, she was returning to wait for her daughter.
Three more days passed by. The rescue work had been resumed amid incredible difficulties. The galleries of approach had fortunately not fallen after the fire-damp explosion; but the air was so heavy and so vitiated that more ventilators had to be installed. Every twenty minutes the pikemen relieved one another. They were advancing; scarcely two metres separated them from their mates. But now they worked feeling cold at their hearts, striking hard only out of vengeance; for the noises had ceased, and the low, clear cadence of the call no longer sounded. It was the twelfth day of their labours, the fifteenth since the catastrophe; and since the morning there had been a death-like silence.
The new accident increased the curiosity at Montsou, and the inhabitants organized excursions with such spirit that the Grégoires decided to follow the fashion. They arranged a party, and it was agreed that they should go to the Voreux in their carriage, while Madame Hennebeau took Lucie and Jeanne there in hers. Deneulin would show them over his yards and then they would return by Réquillart, where Négrel would tell them the exact state of things in the galleries, and if there was still hope. Finally, they would dine together in the evening.
When the Grégoires and their daughter Cécile arrived at the ruined mine, toward three o'clock, they found Madame Hennebeau already there, in a sea-blue dress, protecting herself under her parasol from the pale February sun. The warmth of spring was in the clear sky. M. Hennebeau was there with Deneulin, and she was listening, with listless ear, to the account which the latter gave her of the efforts which had been made to dam up the canal. Jeanne, who always carried a sketch-book with her, began to draw, carried away by the horror of the subject; while Lucie, seated beside her on the remains of a wagon, was crying out with pleasure, and finding it awfully jolly. The incomplete dam allowed numerous leaks, and frothy streams fell in a cascade down the enormous hole of the engulfed mine. The crater was being emptied, however, and the water, drunk by the earth, was sinking, and revealing the fearful ruin at the bottom. Beneath the tender azure of this beautiful day there lay a sewer, the ruins of a town drowned and melted in mud.
