"A gleeful, poetic book…Like the best natural histories, Dirt is a kind of prayer." —Los Angeles Times Book Review "You are about to read a lot about dirt, which no one knows very much about." So begins the cult classic that brings mystery and magic to "that stuff that won't come off your collar." John Adams, Thomas Jefferson, Saint Phocas, Darwin, and Virgil parade through this thought-provoking work, taking their place next to the dung beetle, the compost heap, dowsing, historical farming, and the microscopic biota that till the soil. Whether William Bryant Logan is traversing the far reaches of the cosmos or plowing through our planet’s crust, his delightful, elegant, and surprisingly soulful meditations greatly enrich our concept of "dirt," that substance from which we all arise and to which we all must return.

"A gleeful, poetic book...Like the best natural histories, Dirt is a kind of prayer." --Los Angeles Times Book Review

Combining science, philosophy and natural history with a voracious curosity about how the universe works, Logan takes us on a wonderful journey of discovery as charming as it is fascinating. He has written a unique and thoughtful history of the soil that sustains us, as well as a touching memoir of his own personal connection to it.

Arborist William Bryant Logan recovers the lost tradition that sustained human life and culture for ten millennia. Once, farmers knew how to make a living hedge and fed their flocks on tree-branch hay. Rural people knew how to prune hazel to foster abundance: both of edible nuts, and of straight, strong, flexible rods for bridges, walls, and baskets. Townspeople cut their beeches to make charcoal to fuel ironworks. Shipwrights shaped oaks to make hulls. No place could prosper without its inhabitants knowing how to cut their trees so they would sprout again. Pruning the trees didn’t destroy them. Rather, it created the healthiest, most sustainable and most diverse woodlands that we have ever known. In this journey from the English fens to Spain, Japan, and California, William Bryant Logan rediscovers what was once an everyday ecology. He offers us both practical knowledge about how to live with trees to mutual benefit and hope that humans may again learn what the persistence and generosity of trees can teach.

Dirt, soil, call it what you want—it's everywhere we go. It is the root of our existence, supporting our feet, our farms, our cities. This fascinating yet disquieting book finds, however, that we are running out of dirt, and it's no laughing matter. An engaging natural and cultural history of soil that sweeps from ancient civilizations to modern times, Dirt: The Erosion of Civilizations explores the compelling idea that we are—and have long been—using up Earth's soil. Once bare of protective vegetation and exposed to wind and rain, cultivated soils erode bit by bit, slowly enough to be ignored in a single lifetime but fast enough over centuries to limit the lifespan of civilizations. A rich mix of history, archaeology and geology, Dirt traces the role of soil use and abuse in the history of Mesopotamia, Ancient Greece, the Roman Empire, China, European colonialism, Central America, and the American push westward. We see how soil has shaped us and we have shaped soil—as society after society has risen, prospered, and plowed through a natural endowment of fertile dirt. David R. Montgomery sees in the recent rise of organic and no-till farming the hope for a new agricultural revolution that might help us avoid the fate of previous civilizations.
