Mike McKenzie's brother used to rent a very old house in Kennells Mills. Below the house were some stone wall remains. There were curved stones there that had a porous quality that was different from local stones. When put together, these stones formed a circle about four feet in diameter. They were not fragments; rather they were individual formed pieces. When Mike first saw the stones, there was probably a full mill wheel set, but no one knew what they were for.
When it was confirmed in 2009 that the stone wall remains were that of the actual Kennell's Grist Mill, Mike researched the topic of mill stones, and discovered that the curved stones he had seen where what is known as "Burr" stones. Such stones were pieced and then held together to form a mill stone. Click here for a website that covers this topic. Click here for a section in an old book that describes why and how large millstones were built in segments, and what stone characteristics make the best quality millstone.
When Mike tracked down those burr stones in 2009 to photograph them for Korns.org, he discovered that unfortunately, they had been largely destroyed by being used to form a fire containment circle around a fire pit. The heat from the fire caused them to fragment. What is shown in the photos below is all that remains of the Kennell's Mill burr stones. In the one photo, you can still make out the diverging angle between the the leading and trailing flanks of the stone, as well as the flat bottom, and the generally radially oriented "furrow". The other photo is oriented to more clearly show the flat bottom and the furrow.
