"It's because she's got such fine legs! I say, Chaval, there's enough there for two."

"Oh! we must see. Lift up! Higher! higher!"

Then Chaval, without growing angry at these jokes, turned on her.

"That's it, by God! Ah! she likes dirty jokes. She'd stay there to listen till to-morrow."

Catherine had painfully decided to fill her tram, then she pushed it. The gallery was too wide for her to get a purchase on the timber on both sides; her naked feet were twisted in the rails where they sought a point of support, while she slowly moved on, her arms stiffened in front, and her back breaking. As soon as she came up to the clay wall, the fiery torture again began, and the sweat fell from her whole body in enormous drops as from a storm-cloud. She had scarcely got a third of the way before she streamed, blinded, soiled also by the black mud. Her narrow chemise, as though dipped in ink, was sticking to her skin, and rising up to her waist with the movement of her thighs; it hurt her so that she had once more to stop her task.

What was the matter with her, then, today? Never before had she felt as if there were wool in her bones. It must be the bad air. The ventilation did not reach to the bottom of this distant passage. One breathed there all sorts of vapours, which came out of the coal with the low bubbling sound of a spring, so abundantly sometimes that the lamps would not burn; to say nothing of fire-damp, which nobody noticed, for from one week's end to the other the men were always breathing it into their noses throughout the seam. She knew that bad air well; dead air the miners called it; the heavy asphyxiating gases below, above them the light gases which catch fire and blow up all the stalls of a pit, with hundreds of men, in a single burst of thunder. From her childhood she had swallowed so much that she was surprised she bore it so badly, with buzzing ears and burning throat.

Unable to go farther, she felt the need of taking off her chemise. It was beginning to torture her, this garment of which the least folds cut and burnt her. She resisted the longing, and tried to push again, but was forced to stand upright. Then quickly, saying to herself that she would cover herself at the relay, she took off everything, the cord and the chemise, so feverishly that she would have torn off her skin if she could. And now, naked and pitiful, brought down to the level of the female animal seeking its living in the mire of the streets, covered with soot and mud up to the belly, she laboured on like a cab-hack. On all fours she pushed onwards.

But despair came; it gave her no relief to be naked. What more could she take off? The buzzing in her ears deafened her, she seemed to feel a vice gripping her temples. She fell on her knees. The lamp, wedged into the coal in the tram, seemed to her to be going out. The intention to turn up the wick alone survived in the midst of her confused ideas. Twice she tried to examine it, and both times when she placed it before her on the earth she saw it turn pale, as though it also lacked breath. Suddenly the lamp went out. Then everything whirled around her in the darkness; a millstone turned in her head, her heart grew weak and left off beating, numbed in its turn by the immense weariness which was putting her limbs to sleep. She had fallen back in anguish amid the asphyxiating air close to the ground.

"By God! I believe she's lazing again," growled Chaval's voice.

He listened from the top of the cutting, and could hear no sound of wheels.
