In which Molly continues our summer series on "alchemy" by looking at one of the most pervasive, and yet overlooked, elements in our Western world: dirt. What worlds are contained in a handful of dirt? Featured are poems by Jan Richardson and Walt Whitman, and readings from Wendell Berry and Lindsey Naylor. Music is brought by Rhody Mastin, and includes songs by Tom Waits and Sara Watkins.
