Tracks in the Sea : Matthew Fontaine Maury and the Mapping of the Oceans

Navigation at sea was a matter of guesswork until well into the 19th century. Changing that became the obsession of Matthew Fontaine Maury. While others built railroads, Maury mapped highways of wind and current over the seas. Hearn uses Maury's career as a window on America's maritime development in the 19th century, including the clipper-ship era of the 1850s, the rise of steam and steel, and the Civil War.
