"Wherever I Hang" by Grace Nichols and "Night Mail" by W.H. Auden are two poems that explore different themes and use different literary techniques.
"Wherever I Hang" is a reflective poem that explores the speaker's sense of identity and belonging. The poem is written in free verse, with no set rhyme or meter, which gives the poem a conversational tone. Nichols uses vivid imagery to create a sense of place and to explore the speaker's connection to her surroundings. The poem is also written in the first person, which gives it a personal and intimate feel.
In contrast, "Night Mail" is a more structured poem that describes the journey of a train carrying mail. The poem is written in a set rhyme scheme and meter, which creates a sense of rhythm and movement that mimics the motion of the train. Auden uses personification to give the train a sense of agency and to create a feeling of excitement and anticipation. The poem is also written in the third person, which gives it a more objective tone.
Overall, both poems use different techniques to explore different themes. "Wherever I Hang" is a personal and introspective poem that explores the speaker's sense of identity and belonging, while "Night Mail" is a more objective and descriptive poem that describes the journey of a train.
