...and also of a stone row in Brandywine Creek State Park, and a link to some photos of that wall I took. Here is the link to the photos:
The professor says that the historian for the Park claims these were built by "Italian stone masons" in the 1880s or so. That made me laugh. The Italian stone masons were artists, they would have been totally aghast that someone would suggest they had built such rude stone rows (not even walls) in the middle of nowhere! There are walls, built for the DuPonts, in that area but they are very different from what I have found in the woods. FWIW, my great grandfather was a stone mason and immigrated from Italy in 1880 to the US. I never met him but I imagine he would be quite disappointed if anyone suggested these type of rows were his work. :~) BTW, I am not knocking the people who DID build these walls, but I think they had a different purpose and mindset, and there is artistry in what they did as well, but it is different.
