"Over there—I don't know at all."
"But I shall see you again?"
"No, I think not."
They were silent and remained for a moment facing each other without finding anything to say.
"Then good-bye."
"Good-bye."
While Étienne ascended toward the settlement, Souvarine turned and again went along the canal bank; and there, now alone, he continued to walk, with sunken head, so lost in the darkness that he seemed merely a moving shadow of the night. Now and then he stopped, he counted the hours that struck afar. When he heard midnight strike he left the bank and turned towards the Voreux.
At that time the pit was empty, and he only met a sleepy-eyed captain. It was not until two o'clock that they would begin to get up steam to resume work. First he went to take from a cupboard a jacket which he pretended to have forgotten. Various tools—a drill armed with its screw, a small but very strong saw, a hammer, and a chisel—were rolled up in this jacket. Then he left. But instead of going out through the shed he passed through the narrow corridor which led to the ladder passage. With his jacket under his arm he quietly went down without a lamp, measuring the depth by counting the ladders. He knew that the cage jarred at three hundred and seventy-four metres against the fifth row of the lower tubbing. When he had counted fifty-four ladders he put out his hand and was able to feel the swelling of the planking. It was there. Then, with the skill and coolness of a good workman who has been reflecting over his task for a long time, he set to work. He began by sawing a panel in the brattice so as to communicate with the winding-shaft. With the help of matches, quickly lighted and blown out, he was then able to ascertain the condition of the tubbing and of the recent repairs.
Between Calais and Valenciennes the sinking of mine shafts was surrounded by immense difficulties on account of the masses of subterranean water in great sheets at the level of the lowest valleys. Only the construction of tubbings, frameworks jointed like the stays of a barrel, could keep out the springs which flow in and isolate the shafts in the midst of the lakes, which with deep obscure waves beat against the walls. It had been necessary in sinking the Voreux to establish two tubbings: that of the upper level, in the shifting sands and white clays bordering the chalky stratum, and fissured in every part, swollen with water like a sponge; then that of the lower level, immediately above the coal stratum, in a yellow sand as fine as flour, flowing with liquid fluidity; it was here that the Torrent was to be found, that subterranean sea so dreaded in the coal pits of the Nord, a sea with its storms and its shipwrecks, an unknown and unfathomable sea, rolling its dark floods more than three hundred metres beneath the daylight. Usually the tubbings resisted the enormous pressure; the only thing to be dreaded was the piling up of the neighbouring soil, shaken by the constant movement of the old galleries which were filling up. In this descent of the rocks lines of fracture were sometimes produced which slowly extended as far as the scaffolding, at last perforating it and pushing it into the shaft; and there was the great danger of a landslip and a flood filling the pit with an avalanche of earth and a deluge of springs.
Souvarine, sitting astride in the opening he had made, discovered a very serious defect in the fifth row of tubbing. The wood was bellied out from the framework; several planks had even come out of their shoulder-pieces. Abundant filtrations, pichoux the miners call them, were jetting out of the joints through the tarred oakum with which they were caulked. The carpenters, pressed for time, had been content to place iron squares at the angles, so carelessly that not all the screws were put in. A considerable movement was evidently going on behind in the sand of the Torrent.
