More on Purejoy’s pool:
Beside Trent Barrow near Sherborne is an old pit full of water and so deep that no one has ever been able to measure its depth and it is called the ‘bottomless pit’. One dark and stormy night a coach, horses, driver and passengers plunged into the pit and disappeared, leaving no trace behind. But passersby along the road may still hear, in stormy weather, the sound of galloping horses and wailing voices borne by them on the wind.
