The relationship between Sam and Frightful
One of the most interesting and striking metaphors in the novel is the comparison of Sam's relationship with his falcon, Frightful, to that of a marriage. Making this comparison explicit, Sam notes that "it was like being married to her [Frightful], only better" (George, 92). This metaphor highlights Frightful's importance to Sam's life in the woods, as well as the trust and mutual dependence of their relationship.
The sound of a loon representing loneliness
George also uses a simile to describe the sound of a loon on the lake: "the loon called again, its cry echoing over the water like a wild and lonesome trumpet" (George, 59). This simile creates a detailed image in the reader's mind of the nature that Sam experiences and it captures the sense of isolation that Sam experiences during his time living there. He is free but he is alone.
