Barlow addresses a letter to any journal as a volunteer correspondent (which I frequently find him doing), he will previously have gotten somebody to tell him some tremendous technicality, and will write in the coolest manner, 'Now, sir, I may assume that every reader of your columns, possessing average information and intelligence, knows as well as I do that'--say that the draught from the touch-hole of a cannon of such a calibre bears such a proportion in the nicest fractions to the draught from the muzzle; or some equally familiar little fact. But whatever it is, be certain that it always tends to the exaltation of Mr. Barlow, and the depression of his enforced and enslaved pupil.

Mr. Barlow's knowledge of my own pursuits I find to be so profound, that my own knowledge of them becomes as nothing. Mr. Barlow (disguised and bearing a feigned name, but detected by me) has occasionally taught me, in a sonorous voice, from end to end of a long dinner-table, trifles that I took the liberty of teaching him five-and-twenty years ago. My closing article of impeachment against Mr. Barlow is, that he goes out to breakfast, goes out to dinner, goes out everywhere, high and low, and that he WILL preach to me, and that I CAN'T get rid of him. He makes me a Promethean Tommy, bound; and he is the vulture that gorges itself upon the liver of my uninstructed mind.

CHAPTER XXXV--ON AN AMATEUR BEAT

It is one of my fancies, that even my idlest walk must always have its appointed destination. I set myself a task before I leave my lodging in Covent-garden on a street expedition, and should no more think of altering my route by the way, or turning back and leaving a part of it unachieved, than I should think of fraudulently violating an agreement entered into with somebody else. The other day, finding myself under this kind of obligation to proceed to Limehouse, I started punctually at noon, in compliance with the terms of the contract with myself to which my good faith was pledged.

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.
