His product was even featured in the Lancet for its potential medical benefits. However, he died of unknown causes before being able to profit from exploiting Folly Wood's water source. The wood is now protected as a special site of scientific interest due to its habitat for wading birds, snakes, newts, mushrooms and other rare flora. Local legend has it that the ghosts of two grain delivery men on a horse-drawn cart can be seen or heard chatting and travelling along Mill Lane at twilight. Also, when the spring rains flood the stream, the millpond returns to flood the existing gardens and it is said that the mill wheel can be heard running and grinding corn. These are considered to be benign or signs of good luck. There have been reported supernatural occurrences relating to both Christian and ancient sites in the area. A terrifying ghostly figure was reported in the Wesleyan Methodist Chapel on Mill Lane at several times by children and adult members of the church before the chapel was gutted by fire in the 1960s . In corroborating stories, local residents also reported unexplained "cold spots" and menacing rooks outside the front of the building before thunder storms. The chapel has since been converted into a private residence. Similarly, an apparition in the shape of an intimidating hooded figure brandishing a heavy staff was reported by several local residents to be haunting the derelict mill during the 1950s. This apparition was also reported at night during the mid 1970s in the gardens of residences that were built on the site of the mill, and several times more recently on the tree shaded bridleway to Ruxox Farm. Sightings of such hooded figures have also been reported along the Flit valley in the grounds of Flitwick Manor, the Ridgeway ancient track, Deadman's Hill Clophill, and Chicksands Priory (O'Dell 2008).
