The title promises a retreat, but the poem keeps puncturing that idea. In the first lines, a wet, cold day in the country makes "the poor appear far." The speaker seems to mean that leaving the city for nature also removes us from the people who struggle most. Escape comes with a hint of guilt, since peace for one person can mean blindness to others.
The middle lines are the strangest and most interesting. The speaker says they distrust nature, yet not her "miscarriages." That suggests a liking for what goes wrong, what fails or is cast off, over the tidy, romantic picture of the countryside. The last image, living in the world "like a drawing of a tongue at a bonfire," feels flimsy and out of place: a thin sketch of something soft set beside roaring heat. The mood is wry, uneasy, and slightly detached, as if the speaker can never quite belong anywhere.
