Despite advanced technology, the practice of water witching—using a forked stick to indicate an underground source of water—persists in both rural and urban areas. Water Witching U.S.A. is a lively look at "dowsing," full of personal accounts, historical background, and data from controlled experiments and a nationwide survey. This study includes a collection of photographs, drawings, and historical woodcuts showing the tools, techniques, and early instances of dowsing, as well as cross-sectional views contrasting the dowser's explanation of groundwater with the geologist's.
