Between 1806 and 1831, there had been built, on an average, seven hundred and fifty metres annually, afterwards eight and even ten thousand metres of galleries were constructed every year, in masonry, of small stones, with hydraulic mortar which hardens under water, on a cement foundation.
At two hundred francs the metre, the sixty leagues of Paris’ sewers of the present day represent forty-eight millions.
In addition to the economic progress which we have indicated at the beginning, grave problems of public hygiene are connected with that immense question: the sewers of Paris.
Paris is the centre of two sheets, a sheet of water and a sheet of air.
The sheet of water, lying at a tolerably great depth underground, but already sounded by two bores, is furnished by the layer of green clay situated between the chalk and the Jurassic lime-stone; this layer may be represented by a disk five and twenty leagues in circumference; a multitude of rivers and brooks ooze there; one drinks the Seine, the Marne, the Yonne, the Oise, the Aisne, the Cher, the Vienne and the Loire in a glass of water from the well of Grenelle.
The sheet of water is healthy, it comes from heaven in the first place and next from the earth; the sheet of air is unhealthy, it comes from the sewer.
All the miasms of the cesspool are mingled with the breath of the city; hence this bad breath.
The air taken from above a dung-heap, as has been scientifically proved, is purer than the air taken from above Paris.
In a given time, with the aid of progress, mechanisms become perfected, and as light increases, the sheet of water will be employed to purify the sheet of air; that is to say, to wash the sewer.
The reader knows, that by “washing the sewer” we mean: the restitution of the filth to the earth; the return to the soil of dung and of manure to the fields.
Through this simple act, the entire social community will experience a diminution of misery and an augmentation of health.
At the present hour, the radiation of diseases from Paris extends to fifty leagues around the Louvre, taken as the hub of this pestilential wheel.
We might say that, for ten centuries, the cesspool has been the disease of Paris.
The sewer is the blemish which Paris has in her blood.
The popular instinct has never been deceived in it.
The occupation of sewermen was formerly almost as perilous, and almost as repugnant to the people, as the occupation of knacker, which was so long held in horror and handed over to the executioner.
High wages were necessary to induce a mason to disappear in that fetid mine; the ladder of the cesspool cleaner hesitated to plunge into it; it was said, in proverbial form: “to descend into the sewer is to enter the grave;” and all sorts of hideous legends, as we have said, covered this colossal sink with terror; a dread sink-hole which bears the traces of the revolutions of the globe as of the revolutions of man, and where are to be found vestiges of all cataclysms from the shells of the Deluge to the rag of Marat.
BOOK THIRD.—MUD BUT THE SOUL
CHAPTER I—THE SEWER AND ITS SURPRISES
It was in the sewers of Paris that Jean Valjean found himself.
Still another resemblance between Paris and the sea.
As in the ocean, the diver may disappear there.
The transition was an unheard-of one.
In the very heart of the city, Jean Valjean had escaped from the city, and, in the twinkling of an eye, in the time required to lift the cover and to replace it, he had passed from broad daylight to complete obscurity, from midday to midnight, from tumult to silence, from the whirlwind of thunders to the stagnation of the tomb, and, by a vicissitude far more tremendous even than that of the Rue Polonceau, from the most extreme peril to the most absolute obscurity.
An abrupt fall into a cavern; a disappearance into the secret trap-door of Paris; to quit that street where death was on every side, for that sort of sepulchre where there was life, was a strange instant.
He remained for several seconds as though bewildered; listening, stupefied.
The waste-trap of safety had suddenly yawned beneath him.
Celestial goodness had, in a manner, captured him by treachery.
Adorable ambuscades of providence!
Only, the wounded man did not stir, and Jean Valjean did not know whether that which he was carrying in that grave was a living being or a dead corpse.
His first sensation was one of blindness.
All of a sudden, he could see nothing.
It seemed to him too, that, in one instant, he had become deaf.
He no longer heard anything.
The frantic storm of murder which had been let loose a few feet above his head did not reach him, thanks to the thickness of the earth which separated him from it, as we have said, otherwise than faintly and indistinctly, and like a rumbling, in the depths.
He felt that the ground was solid under his feet; that was all; but that was enough.
He extended one arm and then the other, touched the walls on both sides, and perceived that the passage was narrow; he slipped, and thus perceived that the pavement was wet.
He cautiously put forward one foot, fearing a hole, a sink, some gulf; he discovered that the paving continued.
A gust of fetidness informed him of the place in which he stood.
After the lapse of a few minutes, he was no longer blind.
A little light fell through the man-hole through which he had descended, and his eyes became accustomed to this cavern.
He began to distinguish something.
The passage in which he had burrowed—no other word can better express the situation—was walled in behind him. It was one of those blind alleys, which the special jargon terms branches.
In front of him there was another wall, a wall like night.
The light of the air-hole died out ten or twelve paces from the point where Jean Valjean stood, and barely cast a wan pallor on a few metres of the damp walls of the sewer.
Beyond, the opaqueness was massive; to penetrate thither seemed horrible, an entrance into it appeared like an engulfment.
A man could, however, plunge into that wall of fog and it was necessary so to do.
Haste was even requisite.
It occurred to Jean Valjean that the grating which he had caught sight of under the flag-stones might also catch the eye of the soldiery, and that everything hung upon this chance.
They also might descend into that well and search it.
