Long grind

摘要

I note from the May issue of the Countryman that the National Mills Weekend, held this year on 10 and 11 May, has been an annual event for nearly 20 years and that some 300 windmils and watermills are now welcoming visitors. Mills powered by wind, water, steam, electricit or animal power have for generations been used to grind corn, animal power have for gnerations been used to grind corn, animal feed, bone manure and other products or to provide a source of energy for other operations.
