Thus when a barber and a collier fight, The barber beats the luckless collier-white; The dusty collier heaves his ponderous sack, And big with vengeance beats the barber-black. In comes the brick-dust man, with grime o'erspread, And beats the collier and the barber-red: Black, red, and white in various clouds are tost, And in the dust they raise the combatants are lost.
Christopher Smart (1722 - 1771)
