by Solco Walle Tromp

“The task of this publication is three-fold: first to establish whether the different divining phenomena really exist or are due only to suggestions; secondly, when established, to study all the disturbing factors; thirdly to analyze whether the reactions of diviners (after they have proved to be real) can be used as indicators for certain external physical conditions.” – S. W. Tromp

This exceptionally thorough book is a classic manual for anyone interested in detecting the effects of natural and man-made fields of energy on living plants and humans.
