The settings for the Nick Adams stories can be divided into two categories: nature and the military. The vast majority of the story takes place either in nature itself or in a rural setting which is so closely connected with nature that it amounts to the same. The beauty of nature is an important theme in Hemingway's work, and a kind of symbiotic relationship between man and nature is emphasized throughout. Nick lives off the land at various times, but he is never exploitative. When he a catches a trout that is too small in "Big Two-Hearted River," not only does he let it go, he wets his hand before touching it to make sure it does not contract a fungal infection. When he is not living directly off the land, he always is living very close to it; never does he choose to live in an urban setting altogether remote from the woods and streams with which he is so familiar.
