Two circles of stone, one still and one turning, once fed whole villages — and everything depended on the shallow grooves cut into their faces. A millstone does not crush grain so much as scissor it: furrow crosses furrow, the grain is sheared, and the meal walks outward toward the skirt. Every few hundred working hours the sharp wears away, the mill begins to heat its own flour, and the dresser climbs up with bill and thrift to cut the pattern back into the stone. This book keeps that vanished craft — the harps, the lands, the draft, the raddle proof — where a curious hand can turn it over slowly.
Open the Dressing Bench and lay out a face yourself: choose the stone, count the harps, set the draft of the furrows and the depth at the skirt, then watch the pattern draw itself while the bench counts crossings per turn, inches of cutting edge, the balance between shear and crush, and how many hours the sharp will last before it dulls. The Furrow Atlas holds sixteen entries on dresses, stone grits and the dresser's tools, each with facts a millwright would recognise. Prove a face flat with the phone laid on the stone, keep every dressing in the Stone Log, and answer sixteen questions in the Dresser's Test when the craft has settled into your hands.
