Far away in the small hours a locomotive bellows a warning to make way for its ponderous mass, dragging a long, iron chain of tank and boxcars behind, resigned to its somber duty like a woman hauling water from the creek to the cabin where washing waits in a filthy heap for soap and brush. Miles ahead in the light of day, boys lay a dozen or so pennies on the rails, bright copper spots on the burnished bars of parallel steel. I searched among the cinders between the ties after the red caboose trundled by, the brakeman saying hello and goodbye with a single wave from his copula and found the coin, still warm from its transfiguration, thin and smooth as a lithograph plate ready to be etched with the news of the world or a memorable print of a desert still life littered with a cactus, creosote bush and a steer skull bleached to ivory by the sun and sold in a roadside gift shop where years after the Norfolk and Western line obliterated Lincoln's profile, I slide a quarter into a slot and crank the handle to flatten a penny and emboss it with the words Death Valley.
