Book excerpt: Late eighteenth- and early nineteenth-century landowners in the hinterlands of Baltimore, Maryland, cobbled together workforces from a diverse labor population of black and white apprentices, indentured servants, slaves, and hired workers. This book examines the intertwined lives of the poor whites, slaves, and free blacks who lived and worked in this wheat-producing region along the Mason–Dixon Line. Drawing from court records, the diaries, letters, and ledgers of farmers and small planters, and other archival sources, Max Grivno reconstructs how these poorest of southerners eked out their livings and struggled to maintain their families and their freedom in the often unforgiving rural economy.
