"The great fact demonstrated in this case," says E. C. Rogers, "is, that, under _peculiar conditions_, the human organism gives forth a physical power which, _without visible instruments_, lifts heavy bodies, attracts or repels them according to a law of polarity, overturns them, and produces the phenomena of sound. So far as the mere movement of objects, even of great weight, in connection with certain persons, is concerned, whether in the phenomena of the so called 'spiritual manifestations,' or out of them, the immediate agent is a physical one, and is identical throughout. None but the most ignorant can deny this." For a further delineation of the facts in this case, and deductions therefrom, we refer the reader to the work of Mr. Rogers, on the Dynamic Laws and Relations of Man. "The next case we shall refer to is that of Frederica Hauffe, of the town of Prevorst, in the mountainous parts of Germany. It was found that in her hands, at a very early age, the hazel wand pointed out metals and water. It was also found that, in certain localities, the influences from the earth had a very powerful effect upon her susceptible nerves. It was frequently observed by the one she often accompanied in his walks through solitary places, that though she was skipping ever so gayly by his side, at certain spots a kind of seriousness and shuddering came over her, which for a long time he could not comprehend. He also observed that she experienced the same sensations in churchyards, and in churches where there were graves; and that, in such churches, she never could remain below, but was obliged to repair to the galleries. Superstition, it is true, has always claimed such facts as parts of her ghostly superstructure; but they are too material for this. Frederica was almost constantly in a magnetic state, and in this condition frequently communicated what was taking place at a distance, and was aware of producing sounds in space, and some ways off; but this being found to materially injure her, the habit was abandoned. She had a very high degree of susceptibility to mundane influences, and the effect was, that mineral loads and subterranean currents acted through her upon a simple stick held in her hand.
