In the 351st number of the _Monthly Magazine_, dated March 1st, 1821, there
is a letter to the editor from W. Partridge, dated Boxbridge, Gloucester,
giving several instances of his having successfully used the divining-rod
for the purpose of discovering water. He says the gift is not possessed by
more than one in two thousand, and attributes the power to electricity.
Those persons in whose hands it will work must possess a redundancy of that
fluid. He also states that metals are discovered by the same means.
