^BDowsing.^b Historical photograph of a group of diviners with a variety of objects used for detecting underground water ("dowsing"). The divining (meaning "finding") objects are (from left to right): a whale bone rod, a pendulum suspended from a rod, a watch on a pendulum, another watch on a pendulum and a split cane rod. The rods are held loosely in the practitioner's hands and spontaneously point upwards or downwards when he passes over an underground object such as a spring. The pendulums rotate when over an underground object. Although still widely used, divining has no scientific basis and there is no conclusive evidence that it works.
