The Wonderful Wizard of Oz

Dorothy lived in the midst of the great Kansas prairies, with Uncle Henry, who was a farmer, and Aunt Em, who was the farmer's wife. When Dorothy stood in the doorway and looked around, she could see nothing but the great gray prairie on every side. Today, however, the sky was grayer than usual, and from the far north they heard a low wail of the wind. Uncle Henry suddenly stood up. 'There's a cyclone coming, Em,' he called to his wife.
