Dickinson opens with a quiet act of joining a crowd: some people are away from home, she says, "and I." The pronoun trails at the end of the line like someone slipping in a little late. The speaker is "An Emigrant to be," on the point of leaving rather than already gone, and the first stanza treats the prospect lightly. In "a Metropolis of Homes," being an emigrant is "easy, possibly." That sentence undermines itself. "Easy" sounds sure of itself, and "possibly" takes the assurance back before the stanza ends.
The second stanza explains why the shrug isn't convincing. Leaving may be simple, but living under a new sky is not: "The Habit of a Foreign Sky / We -- difficult -- acquire." The word "difficult" sits fenced in by dashes, wedged between "We" and "acquire," so the line itself struggles to get its verb out. "Habit" is well chosen too. It means a custom built up slowly, and it also suggests something worn, like a garment that has to be broken in. A sky is the one thing you can't shut a door on, so it makes a fitting symbol of unfamiliarity.
The poem ends on a paradox: children "who remain in Face / The more their Feet retire." The lines can be read in more than one way. One picture is of children walking backward, feet withdrawing while faces stay turned toward what they are leaving. Another is of children who keep the look of their family, so that distance only makes the resemblance more obvious. Either way, the body departs faster than the heart. "Retire" matters here as well. It suggests withdrawing, a pulling back, so the feet are not marching boldly forward. The journey is a reluctant retreat, and the more of it there is, the more the face insists on staying.
The poem never says where this journey goes. The "Metropolis of Homes" could be a literal city, another life, or something inward. Metropolis comes from the Greek for "mother city," which gives the phrase a faint suggestion of a place where everyone belongs and a stranger would be sheltered. Some readers may hear a religious echo in it, but the text doesn't confirm that. Dickinson spent most of her life in Amherst, Massachusetts, and it is tempting to read the poem through that fact. The poem doesn't need it, though, and it works for anyone who has felt the gap between leaving a place and getting used to a new one.
The form helps the meaning. Each stanza alternates longer and shorter lines, roughly eight syllables and then six, which recalls the shape of hymn stanzas. That steady, almost singsong pattern makes the poem sound calm and settled, even as the content unsettles it. The rhymes are modest. In the first stanza "be" pairs with "possibly," and the unstressed "-ly" gives the rhyme a tentative, trailing sound that suits the hedging word. In the second, "acquire" and "retire" chime, and the sound links two opposite motions. Learning a new sky and drawing back from an old home are, in effect, the same event.
Dickinson's capital letters on Home, Emigrant, Metropolis, Habit, Foreign Sky, Children, Face and Feet give these ordinary words extra weight, as if each were a small allegorical figure. The two stanzas also work as a pair, with the first offering a casual claim and the second a correction. Leaving is quick, and belonging takes time.
The poem is significant for how much it fits into eight short lines. It turns an abstract idea, the distance between departure and arrival, into physical images of a sky, a face and feet. It also refuses a simple answer. Emigration is "easy, possibly," and the doubt in that "possibly" is what the second stanza goes on to explore. The poem ends with children whose faces stay turned toward home as their feet carry them away, and it leaves the reader to decide which of the two is really leaving.
