Behind the Jardin des Plantes is Salpêtrière with its walls of evil memory, the Salpêtrière of the September massacres, the Salpêtrière whence Madame de Lamotte so easily escaped after her condemnation; with its broad gardens and its ugly covered-yards surrounded by railings, where, as De Goncourt said, "Women madder than their fellows" are confined. The dome, visible from everywhere, commands, like a lighthouse of misery, all this quarter infected by the Bièvre, the poor, sacrificed river, which is now in part walled over; the oily Bièvre, streaked with tannery acids, reddened by skins of sheep recently flayed that steep in it; the Bièvre which flows miserably and sordidly, but yet so picturesquely, amidst starch factories, fellmongers' stores and other works, after traversing the tiny gardens of Gentilly and creating the illusion of a landscape in the quarter of the Fontaine-à-Mulard.

Gone is the time when this ill-starred river washed the banks of smiling meadows and reflected the willows in its clear waters. Tamed, domesticated, adapted to tasks of every sort, unceasingly used by tanners, curriers, tawers, dyers, it flows dirty and putrid! To follow it in its windings, the Rue du Moulin-des-Prés must be ascended, and entrance made into the Rue de Tolbiac. There, through a gate, it enters a dark, dismal passage, whence it will issue only to glide in a kind of sinister-looking canal between black, repulsive manufactories. Here and there, along the scanty banks, a few washerwomen have fixed their tubs on a level with the water, and sing as they dolly their linen; elsewhere, wretched urchins endeavour to catch a stray fish that might have lost its way in the mephitic stream. Then the Bièvre disappears once again and this time underground, coming to view afresh in the Rue des Gobelins. At this spot, some rare traces of a glorious past are discovered. The ancient houses have many of them remained. But how often transformed! The owners of works and of shops, after enslaving the river, have taken possession of the houses bordering it.

THE RUE DE BIÈVRE
Drawn by Heidbrendk

Offices, warehouses, leather stores have invaded the noble mansions of the sixteenth century, and the Bièvre winds, as if ashamed, through poor gardens, like it, fallen from their antique splendour.

THE BIÈVRE TANNERIES
Etching by Martial

Further on, there are more works and tanneries, black corners mean and malodorous, where thousands of rabbit-skins, hanging in mid-air, hard and dry, clash together with a noise of wood. To the very end, the unlucky river, harassed and exploited, cleans blood-stained skins, moves heavy wheels, or washes ghastly offal, amidst a smell as of barege. Finally, it runs to earth once more beneath the Hospital Boulevard, within evil-smelling, dark holes.
