by which they could approach. The worst was that the old pit, now also inundated, no longer communicated with the Voreux; and above the level of the water only a few ends of galleries belonging to the first level were left free. The pumping process would require years, and the best plan would be to visit these galleries and ascertain if any of them approached the submerged passages at the end of which the distressed miners were suspected to be. Before logically arriving at this point, much discussion had been necessary to dispose of a crowd of impracticable plans.
Négrel now began to stir up the dust of the archives; he discovered the old plans of the two pits, studied them, and decided on the points at which their investigations ought to be carried on. Gradually this hunt excited him; he was, in his turn, seized by a fever of devotion, in spite of his ironical indifference to men and things. The first difficulty was in going down at Réquillart; it was necessary to clear out the rubbish from the mouth of the shaft, to cut down the mountain ash, and raze the sloes and the hawthorns; they had also to repair the ladders. Then they began to feel around. The engineer, having gone down with ten workmen, made them strike the iron of their tools against certain parts of the seam which he pointed out to them; and in deep silence they each placed an ear to the coal, listening for any distant blows to reply. But they went in vain through every practicable gallery; no echo returned to them. Their embarrassment increased. At what spot should they cut into the bed? Towards whom should they go, since no once appeared to be there? They persisted in seeking, however, notwithstanding the exhaustion produced by their growing anxiety.
On the first day, Maheude came in the morning to Réquillart. She sat down on a beam in front of the shaft, and did not stir from it till evening. When a man came up, she rose and questioned him with her eyes: Nothing? No, nothing! And she sat down again, and waited still, without a word, with hard, fixed face. Jeanlin also, seeing that his den was invaded, prowled around with the frightened air of a beast of prey whose burrow will betray his booty. He thought of the little soldier lying beneath the rocks, fearing lest they should trouble his sound sleep; but that side of the mine was beneath the water, and, besides, their investigations were directed more to the left, in the west gallery. At first, Philoméne had also come, accompanying Zacharie, who was one of the gang; then she became wearied at catching cold, without need or result, and went back to the settlement, dragging through her days, a limp, indifferent woman, occupied from morning to night in coughing. Zacharie on the contrary, lived for nothing else; he would have devoured the soil to get back his sister. At night he shouted out that he saw, her, he heard her, very lean from hunger, her chest sore with calling for help. Twice he had tried to dig without orders, saying that it was there, that he was sure of it. The engineer would not let him go down any more, and he would not go away from the pit, from which he was driven off; he could not even sit down and wait near his mother, he was so deeply stirred by the need to act, which drove him constantly on.
It was the third day. Négrel, in despair, had resolved to abandon the attempt in the evening. At midday, after lunch, when he came back with his men to make one last effort, he was surprised to see Zacharie, red and gesticulating, come out of the mine shouting:
"She's there! She's replied to me! Come along, quickly!"
He had slid down the ladders, in spite of the watchman, and was declaring that he had heard hammering over there, in the first passage of the Guillaume seam.
"But we have already been twice in that direction," Négrel observed, sceptically. "Anyhow, we'll go and see."
Maheude had risen, and had to be prevented from going down. She waited, standing at the edge of the shaft, gazing down into the darkness of the hole.
Négrel, down below, himself struck three blows, at long intervals. He then applied his ear to the coal, cautioning the workers to be very silent. Not a sound reached him, and he shook his head; evidently the poor lad was dreaming. In a fury, Zacharie struck in his turn, and listened anew with bright eyes, and limbs trembling with joy. Then the other workmen tried the experiment, one after the other, and all grew animated, hearing the distant reply quite clearly. The engineer was astonished; he again applied his ear, and was at last able to catch a sound of aerial softness, a rhythmical roll scarcely to be distinguished, the well-known cadence beaten by the miners when they are fighting against the coal in the midst of danger. The coal transmits the sound with crystalline limpidity for a very great distance. A captain who was there estimated that the thickness of the block which separated them from their mates could not be less than fifty metres. But it seemed as if they could already stretch out a hand to them, and general gladness broke out. Négrel decided to begin at once the work of approach.
When Zacharie, up above, saw Maheude again, they embraced each other.
"It won't do to get excited," Pierronne, who had come for a visit of inquisitiveness, was cruel enough to say. "If Catherine isn't there, it would be such a grief afterwards!"
That was true; Catherine might be somewhere else.
"Just leave me alone, will you? Damn it!" cried Zacharie in a rage. "She's there; I know it!"
Maheude sat down again in silence, with motionless face, continuing to wait.
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
