Étienne was, in fact, now asking himself the meaning of this noise of falling rain. A few large drops had at first sounded on the roof of the cage, like the beginning of a shower, and now the rain increased, streaming down, becoming at last a deluge. The roof must be full of holes, for a thread of water was flowing on to his shoulder and wetting him to the skin. The cold became icy and they were buried in black humidity, when they passed through a sudden flash of light, the vision of a cavern in which men were moving. But already they had fallen back into darkness.
Maheu said:
"That is the first main level. We are at three hundred and twenty metres. See the speed."
Raising his lamp he lighted up a joist of the guides which fled by like a rail beneath a train going at full speed; and beyond, as before, nothing could be seen. They passed three other levels in flashes of light. The deafening rain continued to strike through the darkness.
"How deep it is!" murmured Étienne.
This fall seemed to last for hours. He was suffering for the cramped position he had taken, not daring to move, and especially tortured by Catherine's elbow. She did not speak a word; he only felt her against him and it warmed him. When the cage at last stopped at the bottom, at five hundred and fifty-four metres, he was astonished to learn that the descent had lasted exactly one minute. But the noise of the bolts fixing themselves, the sensation of solidity beneath, suddenly cheered him; and he was joking when he said to Catherine:
"What have you got under your skin to be so warm? I've got your elbow in my belly, sure enough."
Then she also burst out laughing. Stupid of him, still to take her for a boy! Were his eyes out?
"It's in your eye that you've got my elbow!" she replied, in the midst of a storm of laughter which the astonished young man could not account for.
The cage voided its burden of workers, who crossed the pit-eye hall, a chamber cut in the rock, vaulted with masonry, and lighted up by three large lamps. Over the iron flooring the porters were violently rolling laden trams. A cavernous odour exhaled from the walls, a freshness of saltpetre in which mingled hot breaths from the neighbouring stable. The openings of four galleries yawned here.
