Read the following excerpt from Willa Cather's "A Wagner Matinee."
"With the battle between the two motives, with the frenzy of the Venusberg theme and its ripping of strings, there came to me an overwhelming sense of the waste and wear we are so powerless to combat; and I saw again the tall, naked house on the prairie, black and grim as a wooden fortress; the black pond where I had learned to swim, its margin pitted with sun-dried cattle tracks; the rain-gullied clay banks about the naked house, the four dwarf ash seedlings where the dishcloths were always hung to dry before the kitchen door. The world there was the flat world of the ancients; to the east, a cornfield that stretched to daybreak; to the west, a corral that reached to sunset; between, the conquests of peace, dearer bought than those of war."
