   “Interestingly enough, John Mullins, the celebrated English dowser, was able to do this experiment using a forked twig, rather than a pendulum. He claimed to be able to locate nothing but water with his dowsing rod.”

   “The instrument a dowser uses is called a dowsing rod, dowsing stick, doodlebug (when used to locate oil), or divining rod. Almost any item can be used for this purpose: a birch twig, a whalebone, and even a hanger.”
