How did Anton Chekhov revise Wood Demon into Uncle Vanya?

Anton Chekhov transformed his earlier play, The Wood Demon (1888–89), into the theatrical masterpiece Uncle Vanya primarily through the process of cutting.12

While The Wood Demon was described as a long-winded and ineptly facetious four-act play, Chekhov’s revision—conducted between 1890 and 1896—refined the material into a focused, poignant study of aimlessness and hopelessness set within a rural manor house. By removing extraneous elements, he successfully converted the original work into one of his most celebrated dramas, which was subsequently published in 1897.312
