Civilization, in the poem's opening line, behaves like a stern chaperone: it "will not allow for instinct." What follows is a list of bans, each a little more embarrassing than the last: "no dinners of raw mice, / no clawing the eyes of enemies, / no mating / or defecating in the public streets." The repeated "no" reads like signs on a park gate. The humour lies in the clinical word "defecating," which sits beside "mating" as if both were equally scandalous. Pratt makes the rules sound reasonable and slightly absurd at the same time.
The second stanza hands the instinct to someone else, a dog. She catches a scent from "dog, coyote, fox," so the pet is placed in a family of wild animals. The scent is "pungent, / instructive," as if the grass were a page she could read. Then she does something oddly human: she "will turn against my call, ponder, consider." The speaker's voice is the one civilization trains animals to obey, and the dog hesitates over it like a thoughtful reader. When she squats "to make her mark," the phrase hovers between a dog's territory and a signature, and the poem has quietly introduced its subject, which is writing yourself onto a place.
In the third stanza the speaker takes her turn, and the grammar helps. One long sentence unwinds as she walks "between red cedars, young pines," stooping "to move between low branches" and following "a mossy path worn deep by wild feet." The bending is physical and also a lowering of status, bringing a walker closer to the animals who made the path. Then the sentence drops its destination with deliberate bathos: "I felt an insistent urge to pee." After all the Latinate caution of "defecating," the monosyllable lands flat and funny. The title's euphemism, "Nature Calling," has become literal.
The fourth stanza is where the poem pivots. "So there it was" sounds casual, but the next phrase is anything but: "a seizure by immediate beauty." A seizure is involuntary, a thing done to the body, and "immediate" suggests beauty arriving without any polite distance. The only purely visual line, "light filtered through dark pines," is tucked between dashes, as though the light had slipped in sideways. The speaker is "compelled," and what she is compelled to do is speak: "to say in the simplest way I could, / my animal way." Here the bodily act becomes language, and the stanza ends on a comma that pushes us into the two-line finale: "I was here. / This place is mine."
Those last sentences are short, blunt and stripped of imagery. They echo graffiti and the way travellers carve initials into trees, but they are also what the dog's mark means. The word "mine" is the poem's most interesting risk. It can sound like ownership, which is a very civilized idea. In context it seems closer to belonging, a claim made by feeling rather than by deed. The poem does not settle which, and that ambiguity keeps the ending from being merely cute.
Formally, the poem is unrhymed free verse with stanzas of five, five, six, five and two lines. Without rhyme to steer it, the poem relies on speech rhythm, and the long, winding line lengths of the walk contrast sharply with the clipped finish. Small sound echoes still do quiet work: "mice" and "eyes" almost rhyme, "mating" and "defecating" chime, and "mark" finds a distant partner in "dark."
The poem matters because it argues that appreciating nature is not only a matter of looking. Beauty, here, gets into the bones and demands a response from the whole creature. By risking comedy, the poem makes that claim more believable than a solemn tribute would.
