As commonly used, the divining rod is a forked, slender stick of witch hazel; elastic twigs, however, of any sort, or even two sticks of whale-bone fastened together at one end, do not appear to be rejected in the want of the hazel tree. One branch of the twig is taken in each hand between the thumb and forefinger, the two ends pointing down. Holding the stick in this position, the palms towards the face, the gifted operator passes over the surface of the ground; and whenever the upper point of the stick bends over and points downward, there he affirms the spring or metallic vein will be found. Some even pretend to designate the distance below the surface according to the force of the movement, or according to the diameter of the circle over which the action is perceived, one rule being that the depth is half the diameter of this circle; whence, the deeper the object is, below the surface, the further is its influence exerted. It is observable that a rod so held will of necessity turn as the hands are closed more tightly upon it, though this has at first the appearance of serving to resist its motion. From the character of many who use the rod and believe in it, it is also plain that this force is exerted without any intention or consciousness on their part, and that they are themselves honestly deceived by the movement. On putting the experiment to the test by digging, if water is found it proves the genuineness of the operation; if it is not found, something else is, to which the effect is attributed, or the water which attracted the rod is sure to be met with if the digging is only continued deep enough. Some ingenuity is therefore necessary to expose the deception. The writer above referred to succeeded in showing the absurdity of the operation by taking the "diviners" over the same ground twice, the second time blindfolded, and each time marking the points designated by the rod. This, however, is a test to which they are not often willing to subject their art. Some operators do not require a forked twig. There was, in 1857, and may be still, within less than one hundred miles from New York, a man who believed himself gifted in the use of the divining rod, and was occasionally sent for to go great distances, to determine the position of objects of value sunk in the lakes, of ores and of wells of water. He carried several little cylinders of tin, but what they contained was a secret. One had an attraction for iron, another for copper, a third for water, etc. He had in his hand a little rattan cane, which he used as not likely to excite the observation of those he met. Taking one of the cylinders out of his pocket he slipped the rattan into a socket in its end, and holding in his hands the other end of the stick, he set the contrivance bobbing up and down and around. That it was attracted and drawn towards any body of ore in the vicinity he was evidently convinced. * * * * *
