Mr. Tylor also cites a form of the familiar pendulum experiment. Among the Karens a ring is suspended by a thread over a metal basin. The relations of the dead strike the basin, and when he who was dearest to the ghost touches it the spirit twists the thread till it breaks, and the ring falls into the basin. With us a ring is held by a thread over a tumbler, and our unconscious movements swing it till it strikes the hour. How the Karens manage it is less obvious. These savage devices with animated sticks clearly correspond to the more modern 'table-turning.' Here, when the players are honest, the pushing is certainly unconscious.

I have tested this in two ways—first by trying the minimum of conscious muscular action that would stir a table at which I was alone, and by comparing the absolute unconsciousness of muscular action when the table began to move in response to no voluntary push. Again, I tried with a friend, who said, 'You are pushing,' when I gently removed my hands altogether, though they seemed to rest on the table, which still revolved. My friend was himself unconsciously pushing. It is undeniable that, to a solitary experimenter, the table seems to make little darts of its own will in a curious way. Thus, the unconsciousness of muscular action on the part of savages engaged in the experiment with sticks would lead them to believe that spirits were animating the wood. The same fallacy beset the table-turners of 1855-65, and was, to some extent, exposed by Faraday. Of course, savages would be even more convinced by the dancing spoon of Mr. Darwin's tale, by the dancing sticks of the Zulus, and the rest, whether the phenomena were supernormal or merely worked by unseen strings. The same remark applies to modern experimenters, when, as they declare, various objects move untouched, without physical contact.

Still more analogous than turning tables to the savage use of inspired sticks for directing the inquirer to a lost object or to a criminal, is the modern employment of the divining-rod—a forked twig which, held by the ends, revolves in the hands of the performer when he reaches the object of his quest. He, like the savage cited, is occasionally agitated in a convulsive manner; and cases are quoted in which the twig writhes when held in a pair of tongs! The best-known modern treatise on the divining-rod is that of M. Chevreul, 'La Baguette Divinatoire' (1854). We have also 'L'Histoire du Merveilleux dans les Temps Modernes,' by M. Figuier (1860). In 1781 Thouvenel published his 600 experiments with Bleton and others; and Hegel refers to Amoretti's collection of hundreds of cases. The case of Jacques Aymard, who in the seventeenth century discovered a murderer by the use of the rod in true savage fashion, is well known. In modern England the rod is used in the interests of private individuals and public bodies (such as Trinity College, Cambridge) for the discovery of water.

Professor Barrett has lately published a book of 280 pages, in which evidence of failures and successes is collected.[10] Professor Barrett gives about one hundred and fifty cases, in which he was only able to discover, on good authority, twelve failures. He gives a variety of tests calculated to check frauds and chance coincidence, and he publishes opinions, hostile or agnostic, by geologists. The evidence, as a general rule, is what is called first-hand in other inquiries. The actual spectators, and often the owners of the land, or the persons in whose interest water was wanted, having been present, give their testimony; and it is certain that the 'diviner' is called in by people of sense and education, commonly too practical to have a theory, and content with getting what they want, especially where scientific experts have failed.[11]

In Mr. Barrett's opinion, the subconscious perception of indications of the presence of water produces an equally unconscious muscular 'spasm,' which twirls the rod till it often breaks. Yet 'it is almost impossible to imitate its characteristic movement by any voluntary effort.' I have myself held the hands of an amateur performer when the twig was moving, and neither by sight nor touch could I detect any muscular movement on his part, much less a spasm. The person was bailiff on a large estate, and, having accidentally discovered that he possessed the gift, used it when he wanted wells dug for the tenants on the property.

The whole topic is obscure; nor am I concerned here with the successes or failures of the divining-rod. But the movements of the twig have never, to my knowledge, been attributed by modern English performers to the operation of spirits. They say 'electricity.' Mr. Tylor merely writes:

'The action of the famous divining-rod, with its curiously versatile sensibility to water, ore, treasure, and thieves, seems to belong partly to trickery and partly to more or less conscious direction by honester operators.'

As the divining-rod is the only instance in which automatism, whatever its nature and causes, has been found of practical value by practical men, and as it is obviously associated with a number of analogous phenomena, both in civilised and savage life, it certainly deserves the attention of science. But no advance will be made till scientifically trained inquirers themselves arrange and test a large number of experiments. Knowledge of the geological ignorance of the dowsers, examples of fraud on their part, and cases of failure or reported failure, with a general hostile bias, may prevent such experiments from being made by scientific experts on an adequate scale. Such experts ought, of course, to avoid working the dowsers into a state of irritation.

It is just worth while to notice cases in which the rod acts like those of the Melanesians, Africans, and other savages. A Mr. Thomas Welton published an English translation of 'La Verge de Jacob' (Lyon, 1693). In 1651 he asked his servant to bring into the garden 'a stick that stood behind the parlour door. In great terror she brought it to the garden, her hand firmly clutched on it, nor could she let it go.' When Mrs. Welton took the stick, 'it drew her with very considerable velocity to nearly the centre of the garden,' where a well was found. Mr. Welton is not likely to have known of the lately published savage examples. The coincidence with the African and Melanesian cases is, therefore, probably undesigned.

Again, in 1694, the rod was used by le Père Menestrier and others, just as it is by savages, to indicate by its movements answers to all sorts of questions. Experiments of this kind have not been made by Professor Barrett, and other modern inquirers, except by M. Richet, as a mode of detecting automatic action. But it would be just as sensible to use the twig as to use planchette or any other 'autoscopic' apparatus. If these elicit knowledge unconsciously present to the mind, mere water-finding ought not to be the sole province of the rod. In the same class as these rods is the forked twig which, in China, is held at each end by two persons, and made to write in the sand. The little apparatus called planchette, or the other, the ouija, is of course, consciously or unconsciously, pushed by the performers. In the case of the twig, as held by water-seekers, the difficulty of consciously moving it so as to escape close observation is considerable.
