dowsing

dowsing

Occult practice used for finding water, minerals, or other hidden substances. A dowser generally uses a Y-shaped piece of hazel, rowan, or willow wood (also called a dowser or a divining rod). The dowser grasps the rod by its two prongs and appears, while walking, to be receiving transmissions from beneath the earth. If the rod quivers violently or points downward, some buried substance has been located. First practiced in Europe during the Middle Ages, dowsing is most often used to find water but may also be employed to locate precious metals, buried treasure, archaeological remains, or even dead bodies.
