Analysis of Trivia; or, the Art of Walking the Streets of London (excer

Thus far the Muse has trac'd in useful lays
   The proper implements for wintry ways;
   Has taught the walker, with judicious eyes,
   To read the various warnings of the skies.
   Now venture, Muse, from home to range the town,
   And for the public safety risk thy own.

For ease and for dispatch, the morning's best;
   No tides of passengers the street molest.
   You'll see a draggled damsel, here and there,
  From Billingsgate her fishy traffic bear;
  On doors the sallow milk-maid chalks her gains;
  Ah! how unlike the milk-maid of the plains!
  Before proud gates attending asses bray,
  Or arrogate with solemn pace the way;
  These grave physicians with their milky cheer,
  The love-sick maid and dwindling beau repair;
  Here rows of drummers stand in martial file,
  And with their vellum thunder shake the pile,
  To greet the new-made bride. Are sounds like these
  The proper prelude to a state of peace?
  Now industry awakes her busy sons,
  Full charg'd with news the breathless hawker runs:
  Shops open, coaches roll, carts shake the ground,
  And all the streets with passing cries resound.

If cloth'd in black, you tread the busy town
  Or if distinguish'd by the rev'rend gown,
  Three trades avoid; oft in the mingling press,
  The barber's apron soils the sable dress;
  Shun the perfumer's touch with cautious eye,
  Nor let the baker's step advance too nigh;
  Ye walkers too that youthful colours wear,
  Three sullying trades avoid with equal care;
  The little chimney-sweeper skulks along,
  And marks with sooty stains the heedless throng;
  When small-coal murmurs in the hoarser throat,
  From smutty dangers guard thy threaten'd coat:
  The dust-man's cart offends thy clothes and eyes,
  When through the street a cloud of ashes flies;
  But whether black or lighter dyes are worn,
  The chandler's basket, on his shoulder borne,
  With tallow spots thy coat; resign the way,
  To shun the surly butcher's greasy tray,
  Butcher's, whose hands are dy'd with blood's foul stain,
  And always foremost in the hangman's train.

Let due civilities be strictly paid.
  The wall surrender to the hooded maid;
  Nor let thy sturdy elbow's hasty rage
  Jostle the feeble steps of trembling age;
  And when the porter bends beneath his load,
  And pants for breath, clear thou the crowded road.
  But, above all, the groping blind direct,
  And from the pressing throng the lame protect.
  You'll sometimes meet a fop, of nicest tread,
  Whose mantling peruke veils his empty head;
  At ev'ry step he dreads the wall to lose,
  And risks, to save a coach, his red-heel'd shoes;
  Him, like the miller, pass with caution by,
  Lest from his shoulder clouds of powder fly.
  But when the bully, with assuming pace,
  Cocks his broad hat, edg'd round with tarnish'd lace,
  Yield not the way; defy his strutting pride,
  And thrust him to the muddy kennel's side;
  He never turns again, nor dares oppose,
  But mutters coward curses as he goes.

If drawn by bus'ness to a street unknown,
  Let the sworn porter point thee through the town;
  Be sure observe the signs, for signs remain,
  Like faithful land-marks to the walking train.
  Seek not from prentices to learn the way,
  Those fabling boys will turn thy steps astray;
  Ask the grave tradesman to direct thee right,
  He ne'er deceives, but when he profits by 't.

Where fam'd St. Giles's ancient limits spread,
  An inrail'd column rears its lofty head,
  Here to sev'n streets sev'n dials count the day,
  And from each other catch the circling ray.
  Here oft the peasant, with enquiring face,
  Bewilder'd, trudges on from place to place;
  He dwells on ev'ry sign with stupid gaze,
  Enters the narrow alley's doubtful maze,
  Tries ev'ry winding court and street in vain,
  And doubles o'er his weary steps again.
  Thus hardy Theseus with intrepid feet,
  Travers'd the dang'rous labyrinth of Crete;
  But still the wand'ring passes forc'd his stay,
  Till Ariadne's clue unwinds the way.
  But do not thou, like that bold chief, confide
  Thy vent'rous footsteps to a female guide;
  She'll lead thee with delusive smiles along,
  Dive in thy fob, and drop thee in the throng.

When waggish boys the stunted besom ply
  To rid the slabby pavement, pass not by
  E'er thou hast held their hands; some heedless flirt
  Will over-spread thy calves with spatt'ring dirt.
  Where porters hogsheads roll from carts aslope,
  Or brewers down steep cellars stretch
