To her the shepherd said, "I know of none

  Whereto I could direct you, near at hand.

  At least six leagues are distant all, but one,

  Named TRISTRAM'S TOWER, throughout the neighbouring land.

  But not to all men is the door undone;

  For it behoves that they, with lance in hand,

  Achieve their footing first and the defend,

  Who to be lodged within its walls pretend.
