Each pair of millstones had an alarm bell to signal when its hopper required refilling. A leather strap fixed to a cord and buried in the grain held the bell away from a dog on the upright shaft. When the level of grain dropped the strap was released and the bell moved towards the shaft to be nudged by the dog and sound the alarm. Photograph is thought to be by Rex Wailes.
