Evening
Cricket as director
The cricket doesn't just sing—it "set the sun," as if the insect's evening song controls the cosmos. Dickinson gives agency to the smallest creature.
Sewing metaphor
"Seam the day upon"—the workmen are literally stitching closed the day like a piece of fabric. The whole poem treats time as something you can handle and finish.
Twilight personified
Twilight becomes a Victorian caller with "hat in hand," uncertain whether to enter or leave. The formal social ritual mirrors the day's hesitation between staying and going.
Hemispheres at home
The earth's two halves—one in daylight, one in darkness—are "at home" together. Peace comes from this planetary balance, not from conflict resolved.
