On the whole, the evidence for the turning of the wand is a shade better than that for the magical turning of tables. If there are no phenomena of this sort at all, it is remarkable that the belief in them is so widely diffused. But if the phenomena are purely subjective, owing to the conscious or unconscious action of nervous patients, then they are precisely of the sort which the cunning medicine-man observes, and makes his profit out of, even in the earliest stages of society. Once introduced, these practices never die out among the conservative and unprogressive class of peasants; and, every now and then, they attract the curiosity of philosophers, or win the belief of the credulous among the educated classes. Then comes, as we have lately seen, a revival of ancient superstition. For it were as easy to pluck the comet out of the sky by the tail, as to eradicate superstition from the mind of man.
Perhaps one good word may be said for the divining rod. Considering the chances it has enjoyed, the rod has done less mischief than might have been expected. It might very well have become, in Europe, as in Asia and Africa, a kind of ordeal, or method of searching for and trying malefactors. Men like Jacques Aymar might have played, on a larger scale, the part of Hopkins, the witch-finder. Aymar was, indeed, employed by some young men to point out, by help of the wand, the houses of ladies who had been more frail than faithful. But at the end of the seventeenth century in France, this research was not regarded with favour, and put the final touch on the discomfiture of Aymar. So far as we know, the hunchback of Lyons was the only victim of the ‘twig’ who ever suffered in civilised society. It is true that, in rural England, the movements of a Bible, suspended like a pendulum, have been thought to point out the guilty. But even that evidence is not held good enough to go to a jury.
