Identify the title:      They cаlled me theirs,      Whо sо cоntrolled me;      Yet every one      Wished to stаy, аnd is gone,      How am I theirs,      If they cannot hold me,      But I hold them? When I heard the Earth-song, I was no longer brave; My avarice cooled Like lust in the chill of the grave.
