Among the sheep in this bucolic valley is the most complete early ironworks industrial site in America (unrelated to Hopewell Culture). Over 130 years after English settlers built the Saugus Iron Works, a more elaborate and higher volume factory was built here in 1771. Cannon and shot used at Yorktown and in our early Navy were forged here. Inside the red roofed cast house is a giant stone furnace, fed down the chimney by a constant stream of charcoal, limestone and iron ore through the grey wood building above. For over 100 years, the giant water wheel (which still turns today) blasted air into the crucible to pour iron ingots into the floor inside.

Upon arrival, I recalled visiting here at age 12, a number of years ago, on a school trip to Philadelphia and DC. One of my teachers still volunteers at a military park nearby. Each step in the process can be seen here, basically unchanged, from wood pile, to charcoal, worker housing and eventually to pig iron, ready for sale. Many great forests were felled for America to rise to the top of the iron and steel industry, but I notice that the owners kept many of their own fine old trees for shade and beauty. Now that we can harness nearly infinite clean, non-destructive power from the sun, I hope we make progress restoring nature.
