Here are some photos of the New England stone walls from when I recently went hiking. The stone walls of New England were built mostly from between 1750 – 1850. These walls were likely built by farmers to keep livestock in, rather than to keep people out. In New England, the railroad through Concord was built a year before Thoreau settled himself at Walden, and about 30 years before the Transcontinental railroad. New England farmers had opportunity with the railroad to get product such as wool to the cities. That said, anyone who lives in New England may take these walls for granted because they are everywhere, on private property, by roadsides, on hiking trails. Any historians out there can contribute more detail in the comments if you like. I’m just a poet who values ghosts of the past and thinks these walls are cool.
