On such an occasion, it is my habit to regard my walk as my beat, and myself as a higher sort of police-constable doing duty on the same. There is many a ruffian in the streets whom I mentally collar and clear out of them, who would see mighty little of London, I can tell him, if I could deal with him physically.

Issuing forth upon this very beat, and following with my eyes three hulking garrotters on their way home, – which home I could confidently swear to be within so many yards of Drury-lane, in such a narrow and restricted direction (though they live in their lodging quite as undisturbed as I in mine), – I went on duty with a consideration which I respectfully offer to the new Chief Commissioner, – in whom I thoroughly confide as a tried and efficient public servant. How often (thought I) have I been forced to swallow, in police-reports, the intolerable stereotyped pill of nonsense, how that the police-constable informed the worthy magistrate how that the associates of the prisoner did, at that present speaking, dwell in a street or court which no man dared go down, and how that the worthy magistrate had heard of the dark reputation of such street or court, and how that our readers would doubtless remember that it was always the same street or court which was thus edifyingly discoursed about, say once a fortnight.

Now, suppose that a Chief Commissioner sent round a circular to every division of police employed in London, requiring instantly the names in all districts of all such much-puffed streets or courts which no man durst go down; and suppose that in such circular he gave plain warning, ‘If those places really exist, they are a proof of police inefficiency which I mean to punish; and if they do not exist, but are a conventional fiction, then they are a proof of lazy tacit police connivance with professional crime, which I also mean to punish’ – what then? Fictions or realities, could they survive the touchstone of this atom of common sense? To tell us in open court, until it has become as trite a feature of news as the great gooseberry, that a costly police-system such as was never before heard of, has left in London, in the days of steam and gas and photographs of thieves and electric telegraphs, the sanctuaries and stews of the Stuarts! Why, a parity of practice, in all departments, would bring back the Plague in two summers, and the Druids in a century!
