ABOUT 1870 IT WAS CONVERTED FROM A SAW MILL TO A FLOUR MILL & OPERATED INTO THE 1890s. THIS STONE WAS THE UPPER MOVABLE STONE, THE RUNNER, & RESTED ON A SHAFT FROM BELOW, THE SPINDLE. THE POWER TO TURN THE SPINDLE WAS PROVIDED BY THE MILL'S WATER WHEEL. THE LOWER STONE WAS STATIONARY & CALLED A BUHR-STONE. THE SPACE BETWEEN THE STONES WAS MAINTAINED BY ADJUSTMENT MECHANISMS UNDER THE SPINDLE. THE HAND-CUT GROOVES IN THE STONE MATCHED A SECOND SET OF GROOVES IN THE STATIONARY BUHR-STONE. THE GROOVES PROVIDED A SHEARING, SQUEEZING & CRUSHING ACTION ON THE GRAIN.
