PASSAGE 20 — Complex Fiction Excerpt
The summer of 1924 in Blackwood County was defined by drought. The soil cracked into gray geometric plates, and the creek shrank to a trickle of stagnant green water. Farmer Vance stood on his porch, watching his neighbor, Mr. Henderson, install an automated gasoline-powered irrigation pump drawn from the shared pond. Within four days, Henderson's corn fields were lush and green, while Vance's crops withered. When Vance approached the pond edge, he noticed the water level had dropped three feet, exposing the muddy roots of the ancient boundary oaks. Henderson smiled from his tractor, shouting over the engine noise, 'Progress moves ahead without rain, Vance!' Vance said nothing, but that evening he walked to his shed and brought out his grandfather's wooden water-divining rod and a spade.
