• A nightcap decked his brows instead of bay,
  A cap by night — a stocking all the day!
  • Description of an Author's Bedchamber (1760)

• Men may be very learned, and yet very miserable; it is easy to be a deep geometrician, or a sublime astronomer, but very difficult to be a good man. I esteem, therefore, the traveller who instructs the heart, but despise him who only indulges the imagination. A man who leaves home to mend himself and others, is a philosopher; but he who goes from country to country, guided by the blind impulse of curiosity, is only a vagabond.

  It's like sending them ruffles, when wanting a shirt.

  May live to fight another day;
  But he who is in battle slain
  Can never rise and fight again.

  On hope the wretch relies;
  And e'en the pang preceding death
  Bids expectation rise.

  Adorns and cheers our way;
  And still, as darker grows the night,
  Emits a brighter ray.

  Or by the lazy Scheldt, or wandering Po.

  Catch every nerve, and vibrate through the frame.
  Their level life is but a mouldering fire,
  Unquenched by want, unfanned by strong desire.
  • Line 219

• They please, are pleased, they give to get esteem,
  Till, seeming blest, they grow to what they seem.
  • Line 265

  Embosomed in the deep where Holland lies.
  Methinks her patient sons before me stand,
  Where the broad ocean leans against the land.

The Deserted Village (1770)

• The bashful virgin's sidelong looks of love,
  The matron's glance that would those looks reprove.
  • Line 29

• Ill fares the land, to hastening ills a prey,
  Where wealth accumulates, and men decay;
  Princes and lords may flourish, or may fade;
  A breath can make them, as a breath has made;
  But a bold peasantry, their country's pride,
  When once destroyed, can never be supplied.
  • Line 51

• His best companions, innocence and health;
  And his best riches, ignorance of wealth.

• How happy he who crowns in shades like these,
  A youth of labour with an age of ease.

  To tempt its new-fledged offspring to the skies,
  He tried each art, reproved each dull delay,
  Allured to brighter worlds, and led the way.

• Truth from his lips prevailed with double sway,
  And fools, who came to scoff, remained to pray.

• Even children followed with endearing wile,
  And plucked his gown, to share the good man's smile.
  • Line 183

• A man severe he was, and stern to view;
  I knew him well, and every truant knew:
  Well had the boding tremblers learned to trace
  The day's disasters in his morning face;
  Full well they laughed with counterfeited glee,
  At all his jokes, for many a joke had he;
  Full well the bust whisper, circling round,
  Conveyed the dismal tidings when he frowned;
  Yet he was kind; or if severe in aught,
  The love he bore to learning was in fault;
  The village all declared how much he knew;
  'Twas certain he could write, and cipher too.
  • Line 197

• In arguing too, the parson owned his skill,
  For e'en though vanquished, he could argue still;
  While words of learned length, and thundering sound
  Amazed the gazing rustics ranged around;
  And still they gazed, and still the wonder grew,
  That one small head could carry all he knew.

• Where village statesmen talked with looks profound,
  And news much older than their ale went round.
  • Line 223

• The whitewashed wall, the nicely sanded floor,
  The varnished clock that clicked behind the door;
  The chest contrived a double debt to pay,
  A bed by night, a chest of drawers by day.
  • Line 227

• To me more dear, congenial to my heart,
  One native charm, than all the gloss of art.
  • Line 253

• And, ev'n while fashion's brightest arts decoy,
  The heart distrusting asks, if this be joy.
  • Line 263

• Her modest looks the cottage might adorn,
  Sweet as the primrose peeps beneath the thorn.
  • Line 329

• Thou source of all my bliss, and all my woe,
  That found'st me poor at first, and keep'st me so.
  • Line 413

Retaliation (1774)

• Our Garrick's a salad; for in him we see
  Oil, vinegar, sugar, and saltness agree!
  • Line 11

• Here lies our good Edmund, whose genius was such,
  We scarcely can praise it, or blame it too much;
  Who, born for the universe, narrowed his mind,
  And to party gave up what was meant for mankind...
  Who, too deep for his hearers, still went on refining.
  And thought of convincing while they thought of dining;
  Though equal to all things, for all things unfit;
  Too nice for a statesman, too proud for a wit.

  An abridgment of all that was pleasant in man.

  He shifted his trumpet and only took snuff.
