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.
On y respirait toutes sortes de vapeurs qui sortaient du charbon avec un petit bruit bouillonnant de source, si abondantes parfois, que les lampes refusaient de bruler; sans parler du grisou, dont on ne s'occupait plus, tant la veine en soufflait au nez des ouvriers, d'un bout de la quinzaine a l'autre.
