This poem treats feelings like currency. Ecstasy costs anguish, beloved hours are purchased with years of pain, and tears pile up in coffers (treasure chests). The entire system runs on exact exchange rates—notice ratio in line 3.
CONTEXT Dickinson wrote this around 1858-1860, during her most productive period but also increasing isolation. She'd experienced several losses and was beginning her withdrawal from Amherst society. The poem's accounting language reflects 19th-century economic thinking, but also Calvinist New England's obsession with moral ledgers—every pleasure must be paid for.
The financial metaphors get progressively smaller and meaner. Stanza one deals in abstract ecstasy and anguish. Stanza two descends into petty cash: pittances (meager wages), farthings (nearly worthless coins), money so small it's bitter to even count it. The poem moves from cosmic balance to penny-pinching misery. That shift matters—it suggests life doesn't just balance joy with sorrow, it *shortchanges* you, paying out suffering in amounts that far exceed what the happiness was worth.
