وصف الناشر
The Mason-Dixon Line’s history, replete with property disputes, persecution, and ideological conflicts, traverses our country’s history from its founding to today. We live in a world of boundaries — geographic, scientific, cultural, and religious. One of America’s most enduring boundaries is the Mason-Dixon Line, most associated with the divide between the North and the South and the right to freedom for all people. Sibert Medal–winning author Sally M. Walker traces the tale of the Mason-Dixon Line through family feuds, brave exploration, scientific excellence, and the struggle to define a cohesive country. But above all, this remarkable story of surveying, marking, and respecting lines of demarcation will alert young history buffs to their guaranteed right and responsibility to explore, challenge, change, and defend the boundaries that define them.
PUBLISHERS WEEKLY
Walker (Secrets of a Civil War Submarine) presents an exhaustively researched account of the people and events surrounding the creation of the Mason-Dixon Line. The author goes back to 16th-century England when the Calvert and Penn families were granted charters for the Maryland and Pennsylvania colonies, respectively. Using the boundary metaphor extensively, the packed-with-facts narrative covers historical, political, religious, geographical, and scientific terrain. The bulk of the story takes readers step by chronological step through Charles Mason's meticulous astronomical observation work and Jeremiah Dixon's laborious ground survey in the 1760s as they delineate a boundary that would take on increased significance in the run-up to the Civil War. Thirteen chapters include breakout sidebars that thoroughly contextualize the Mason-Dixon Line, from information on celestial navigation and the Quaker religion to the Fugitive Slave Act of 1850 and sidereal time. Scientific and mathematical concepts are clearly presented and well-defined, but may make for more challenging reading. Archival photos, maps, and diagrams supplement the text, as do extensive source notes, a bibliography, and an index. Ages 10 up.
