Sing on, there in the swamp! singer bashful and tender! I hear your notes—I hear your call; I hear—I come presently—I understand you; But a moment I linger—for the lustrous star has detain’d me; The star, my departing comrade, holds and detains me.
The speaker feels that their voice can only be heard through feeling over logical terms. Personification is used as the star is called a comrade and the bird is a singer, signaling that they have a more powerful meaning to their connection.
