Famous quotes containing the words strand and/or ended:

    The annals of this voracious beach! who could write them, unless it were a shipwrecked sailor? How many who have seen it have seen it only in the midst of danger and distress, the last strip of earth which their mortal eyes beheld. Think of the amount of suffering which a single strand had witnessed! The ancients would have represented it as a sea-monster with open jaws, more terrible than Scylla and Charybdis.
    Henry David Thoreau (1817–1862)

    It all ended with the circuslike whump of a monstrous box on the ear with which I knocked down the traitress who rolled up in a ball where she had collapsed, her eyes glistening at me through her spread fingers—all in all quite flattered, I think. Automatically, I searched for something to throw at her, saw the china sugar bowl I had given her for Easter, took the thing under my arm and went out, slamming the door.
    Vladimir Nabokov (1899–1977)
