Answer:
The poet is trying to get the reader to make a comparison.
Step-by-step explanation:
A metaphor is a figure of speech that refers to a particular thing by mentioning a different one. This is done for rhetorical effect, in order to clarify a particular concept, or to identify similarities between two ideas. When a poet uses a metaphor in his work, he usually does so because he wants to get the reader to make a comparison.
