And like that ... he's humming an old Creole slave song

Edmund Clarence Stedman, ed., Bartleby’s: An American Anthology:

Bring Back My Chains

Freedom! I feel it when too late,

Like spring wind on a blasted tree,

A waft of mockery and hate!

Bring back my chains, O cruel Fate!

Bring youth and slavery back to me;

Bring back the lash, the hound, the pain,

So that my own love come again!
