"When I see birches bend to left and right ..."See in text(Text of the Poem)
Frost wrote “Birches” in blank verse—unrhymed iambic pentameter. The poem has no stanza breaks or other such ordering schema, only sixty lines of unobstructedly flowing pentameter. The uninterrupted, often enjambed blank verse gives the poem a flowing quality that imitates the speaker’s stream of consciousness as it moves organically from thought to thought.
