Entering a narrow street, guarded by posts and cross-bars, a few steps from the crowded thoroughfare brought you into a frightful region, the refuge, it was easy to perceive, of half the lawless characters infesting the metropolis. The coarsest ribaldry assailed your ears, and noisome odours afflicted your sense of smell. As you advanced, picking your way through kennels flowing with filth, or over putrescent heaps of rubbish and oyster-shells, all the repulsive and hideous features of the place were displayed before you. There was something savagely picturesque in the aspect of the place, but its features were too loathsome to be regarded with any other feeling than disgust. The houses looked as sordid, and as thickly crusted with the leprosy of vice, as their tenants. Horrible habitations they were, in truth. Many of them were without windows, and where the frames were left, brown paper or tin supplied the place of glass; some even wanted doors, and no effort was made to conceal the squalor within. On the contrary, it seemed to be intruded on observation. Miserable rooms, almost destitute of furniture; floors and walls caked with dirt, or decked with coarse flaring prints; shameless and abandoned-looking women; children without shoes and stockings, and with scarcely a rag to their backs: these were the chief objects that met the view. Of men, few were visible--the majority being out on business, it is to be presumed; but where a solitary straggler was seen, his sinister looks and mean attire were in perfect keeping with the spot. So thickly inhabited were these wretched dwellings, that every chamber, from garret to cellar, swarmed with inmates. As to the cellars, they looked like dismal caverns, which a wild beast would shun. Clothes-lines were hung from house to house, festooned with every kind of garment. Out of the main street branched several alleys and passages, all displaying the same degree of misery, or, if possible, worse, and teeming with occupants. Personal security, however, forbade any attempt to track these labyrinths; but imagination, after the specimen afforded, could easily picture them. It was impossible to move a step without insult or annoyance. Every human being seemed brutalised and degraded; and the women appeared utterly lost to decency, and made the street ring with their cries, their quarrels, and their imprecations. It was a positive relief to escape from this hotbed of crime to the world without, and breathe a purer atmosphere. Such being the aspect of the Rookery in the daytime, what must it have been when crowded with its denizens at night! Yet at such an hour it will now be necessary to enter its penetralia.
