Why did ezra pound reduce "in a station of the metro" from 30 lines to two?

Ezra Pound reduced his poem "In a Station of the Metro" from 30 lines to two because he was a Modernest. He worked in extremes and either wrote minimalist works that consisted of two lines or he wrote epic works that consisted of hundreds of lines. He also refused to repeat himself throughout his career as a poet. The Modernism movement started at the beginning of the twentieth century. It broke away from traditional structures such as rhyme and meter. Modernism created free verse.
