Commemorating the Demise of the Grist Mill: Headstones are supposed to memorialize the dead, but here is one that memorializes the death of an entire era. The piedmont of North Carolina provided many opportunities to harness the power of running water, and many families enjoyed the steady income that came from running a mill. Speaking of running, this is a runner stone. What does it have in common with the cemetery's other markers? They're all made of granite. Pineview Cemetery.
