The River (1938, 32 min.).
"The plow that broke the plains" depicts the social and economic history of the Great Plains from the settlement of the prairies by cattlemen and farmers through the World War I boom to drought and depression. "The river" traces life in the Mississippi River Valley during the previous 150 years, showing the consequences of sharecropping, soil exhaustion, unchecked erosion and floods, and concludes with scenes of regional planning, TVA development and federal efforts.
