- The poem "Lines Written in March" by William Wordsworth describes the arrival of spring. - Wordsworth uses vivid imagery and nature descriptions to portray the happiness of spring's return - the cock crows, the stream flows, small birds twitter, and the blue sky prevails as winter retreats like a defeated army. - Through rhyme and repetition of words like "anon," the poet captures the joy felt by humans and nature alike as winter ends and a new season begins.
