George Washington spent more of his working life farming than he did at war or in political office. For over forty years, he devoted himself to the improvement of agriculture. Washington at the Plow depicts the "first farmer of America" as a leading practitioner of the New Husbandry, a transatlantic movement that spearheaded advancements in crop rotation. A tireless experimentalist, Washington pulled up his tobacco and switched to wheat production, leading the way for the rest of the country. He filled his library with the latest agricultural treatises and pioneered land-management techniques that he hoped would guide small farmers, strengthen agrarian society, and ensure the prosperity of the nation. He saw enslaved field workers and artisans as means of agricultural development and tried repeatedly to adapt slave labor to new kinds of farming. But Washington eventually found that forced labor could not achieve the productivity he desired. His inability to reconcile ideals of scientific farming and rural order with race-based slavery led him to reconsider the traditional foundations of the Virginia plantation. As Bruce Ragsdale shows, it was the inefficacy of chattel slavery, as much as moral revulsion at the practice, that informed Washington's famous decision to free his slaves after his death.
