Dowsing is a folklore process used to locate an unknown, such as the best location for a water well, by the use of a hand-held device. The process is commonly know as water witching, divining, dowsing or radiesthesia. The practice continues despite the lack of a proven scientific basis. This research develops an experiment to test the claims of a dowser. Specific procedures are established and statistical theory is applied to determine if one man can identify which of five water lines has flowing water in it better than a chance operator could achieve. The statistical analysis uses Abraham Walds sequential analysis procedures for establishing when to accept a hypothesis in a binomial situation. The dowsers performance proved to be better than chance. Further research is recommended.
