There are days when br one should be able br to pluck off one's head br like a dented or worn br helmet, straight from br the nape and collarbone br (those crackling branches!) br br and place it firmly down br in the bed of a flowing stream. br Clear, clean, chill currents br coursing and spuming through br the sour and stale compartments br of the brain, dimmed eardrums, br bleared eyesockets, filmed tongue.
