The words which characterize it in administrative language are sonorous and dignified. What used to be called a gut is now called a gallery; what used to be called a hole is now called a surveying orifice. Villon would no longer meet with his ancient temporary provisional lodging. This network of cellars has its immemorial population of prowlers, rodents, swarming in greater numbers than ever; from time to time, an aged and veteran rat risks his head at the window of the sewer and surveys the Parisians; but even these vermin grow tame, so satisfied are they with their subterranean palace. The cesspool no longer retains anything of its primitive ferocity. The rain, which in former days soiled the sewer, now washes it. Nevertheless, do not trust yourself too much to it. Miasmas still inhabit it. It is more hypocritical than irreproachable. The prefecture of police and the commission of health have done their best. But, in spite of all the processes of disinfection, it exhales, a vague, suspicious odor like Tartuffe after confession.
