It was quite natural, that those who had the blind-alley Vide-Gousset, 100 or the Rue Coupe-Gorge, 101 for the scene of their daily labor, should have for their domicile by night the culvert of the Chemin-Vert, or the catch basin of Hurepoix. Hence a throng of souvenirs. All sorts of phantoms haunt these long, solitary corridors; everywhere is putrescence and miasma; here and there are breathing-holes, where Villon within converses with Rabelais without.

The sewer in ancient Paris is the rendezvous of all exhaustions and of all attempts. Political economy therein spies a detritus, social philosophy there beholds a residuum.
