Savoy seems to be a specially favorable region for the development of this peculiar gift, for if in Cornwall one out of every forty men is believed to possess it, in Savoy the divining rod is in the hands of nearly every one. But what marks the talent in this case as peculiar is that it is by no means limited to the discovery of water, but extends to other things likewise. A very wealthy family, called Collomb, living in Cessens, boasted of more than one member who was able, by the aid of the rod and with bandaged eyes, to discover not only pieces of money, but even needles, evidently cases of personal susceptibility to the presence of metals, aided by electric currents. Once, at least, the gift was made useful. A number of bags filled with wheat had been stolen from a neighboring house, and the police were unable to discover the hiding-place. At the request of his friends one of the Collombs undertook the search with the aid of the divining rod; he soon found the window through which the bags had been handed out; he then followed the track along the banks of the river Cheran, and asserted that the thief had crossed to the other side. At that time nothing more was discovered; but soon afterwards a miller living across the river was suspected, the bags were found, and the culprit sent to the galleys. (_Revue Savoisienne_, April 15, 1852.) Dr. Mayo mentions, mainly upon the authority of George Fairholm, a number of instances in which persons belonging to all classes of society have exhibited the same gift, but ascribes its efficacy to the presence of currents of Od. The divining rod, originally a twig of willow or hazel, is often made of metal, and the impression prevails that in such cases an electric current, arising from the subterranean water or metals, enters the diviner's body by the feet, passes through him, and finally affects the two branches of the rod, which represent opposite poles. It is certain that when the electric current is interrupted, the power of the divining rod is suspended. Dr. Mayo tells us of a lady of his acquaintance in Southampton, who at his request used a divining rod of copper and iron wire, made after the fashion of the usual hazel rod; it answered the purpose fully, but when the ends touched by her hands were covered with sealing-wax, it became useless; as soon as she put her fingers in contact with the unprotected wire, the power instantly returned. This certainly seemed to be strong evidence of the existence of an electric current. Nevertheless, many believe that the divining rod acts in all cases simply as an extension of the arms, and thus serves to make the vibrations of the muscles more distinct. It is by this theory they explain the fact which has caused serious trouble to careful inquirers like Count Tristan and Dr. Mayo, that the gift of using the divining rod varies with the state of health in the individuals in whom it has been discovered.
