THE vision will vanish for ever, 
    That gildeth this moment thy track; 
And in vain were the noblest endeavour 
    To call the enchantment back. 
 
Yet pine not; a balm—an ovation 
    Is thine in the thought, that the day 
Will come when thy bleak desolation 
    Will pass like thy vision away.
Joseph Skipsey
