"Vain vision! when the changing world each day Sees some such lordly pleasance pass away; When the mere stripling knows my symbols all Worn tokes, heaven hypothetical, Nature indifferent, and the dreams of men Figments of longing which we must condemn. Yet keep these plants, O Man! a kinder time May yet be moved by them to better rhyme, Or moved, like me, to place his pleasure low, On the firm Earth, whence Men and Blossoms grow."
