CHAPTER 1 HISTORY OF WINDMILLS

This design allowed for much larger and taller mills than the "post mill". The advantage of the design was that the taller mills allowed an extra length of sails to increase the power output. The sails were mostly octagonal in shape. By the end of the 14 century, the smock mill was replaced by the tower mill design as depicted in figure 1.9.
