How can we explain this belief on the one hand and the trickery on the other? First let us examine the mechanism involved in the upward twisting of the twig. Suppose you take a tough and springy forked twig, each arm of the fork being about nine or ten inches long, hold it with the apex away from you, and, with your palms facing together and your finger-tips pointing upward, place the thumb and little finger of each hand inside the fork at the places marked T and F. Now close each hand, and you have each arm of the fork firmly gripped; next, keeping your elbows well in, bend the arms of the fork outward as in Fig. 2, with your palms now looking upward. You will then find that a sort of trigger action tends to occur, and by a slight pressure of your ring-fingers against the twig you can make it rise. Still gripping firmly and pressing your hands a little together you will find it continues to rise, and by bending your hands downwards at the wrists and pressing your elbows to your side you can easily persuade an observer, and perhaps yourself, that you are trying to hold the twig down. You may even find that it leaves a pressure mark on your little finger, which you can show as evidence of how you tried to restrain it. If one arm of the fork is weaker than the other it may break, and that of course will be conclusive proof of the working of a mysterious power. So we see there is nothing very strange in the man believing that his muscular action was not responsible for the moving of the twig; but his two-sided make-up--piety on one side and trickery on the other--can best be explained by a dissociation, with repression of the knowledge of trickery as far as the main personality is concerned. We might split up his consciousness like this:-- Piety, and belief in Knowledge of the means water-divining employed. Hypersensitive as the gift of God. mechanism for carrying it on. Perhaps it is unfair to talk of trickery; he may have deceived himself from the start and never known that he was deceiving any one. At first I pictured him as learning the trick from some one else, trying it on with his friends--maybe across a bridge over a stream--and being taken seriously, and then, when he could not escape from his reputation without owning up to the fraud, being compelled for his peace of mind to repress the deceit complex and carry on as a Dissociate. The man himself would be the last person to gain information from, for his repression, however it began, is now complete.
