In Frost's poem, "Fire and Ice," he utilizes these natural elements to reflect emotions of desire and hate. The image of red and blue and burning and cold are what become apparent in our minds as we read this poem. Frost's use of imagery allows the ready to put their own imagination into play and create their own images as to what is going on. Also, in "The Oven Bird," Frost uses nature imagery to describe how effective the "singer" is and how her voice is heard. Because the topic of much of his poems is already referring to nature, like "Mending Walls" and "Stopping by Woods on a Snowy Evening," the images are going to reflect nature.
Moreover, even in the poems that have titles that do not pertain to nature, like "Into My Own" and "Nothing Gold Can Stay," nature is included. In "Into My Own," Frost is showing how he is becoming who he is. He is describing how he has discovered himself and discovered certain truths. This poem is about himself and his self-discovery, yet he has integrated nature to show how nature has held him back and has sheltered him from realizing the truths. He creates the image of a "dark tree" and "sand" and then makes it clear that nature is what has helped him evolve and develop.
Frost relies on nature and its processes to reveal what he has gone though. He uses things that occur in nature to demonstrate what has happened to him, and how he feels about it. Through the use of nature imagery, he develops a parallel with the processes in nature and allows the ready to relate his situation to something they may be familiar with. This strategy is important because it allows the reader to understand the emotion put into a poem. This not only allows for better understanding but also is what creates Frost's unique style.
