GOOD-BYE

Good-bye, proud world! I'm going home: Thou art not my friend, and I'm not thine. Long through thy weary crowds I roam; A river-ark on the ocean brine, Long I've been tossed like the driven foam: But now, proud world! I'm going home.

Good-bye to Flattery's fawning face; To Grandeur with his wise grimace; To upstart Wealth's averted eye; To supple Office, low and high; To crowded halls, to court and street; To frozen hearts and hasting feet; To those who go, and those who come; Good-bye, proud world! I'm going home.

I am going to my own hearth-stone, Bosomed in yon green hills alone,-- secret nook in a pleasant land, Whose groves the frolic fairies planned; Where arches green, the livelong day, Echo the blackbird's roundelay, And vulgar feet have never trod A spot that is sacred to thought and God.

O, when I am safe in my sylvan home, I tread on the pride of Greece and Rome; And when I am stretched beneath the pines, Where the evening star so holy shines, I laugh at the lore and the pride of man, At the sophist schools and the learned clan; For what are they all, in their high conceit, When man in the bush with God may meet?
