These stones were used in this mill from the time it opened in 1847 until 1890 when they were replaced by roller mills. These comprise one set, or "run", of stones with a bottom stationary stone ("bedstone") and a top, rotating stone ("runner"). At Wolcott Mill, three run of stones were operated at the same time.
The stones are made up of many pieces. These came from France, and were fitted and held together by an outside iron band. French "Buhr" stones were considered the best type for grinding grain.
Through use, the stones gradually wore down and would need periodic "Dressing". This consisted of separating the stones and leveling the grinding surfaces before chiseling in radiating grooves. These grooves, or "furrows", aided grinding by shearing off husks, directing the product to the outer edge, and allowing air movement for cooling.
