tracing veins. These are simple rods bent
into the shape of an "L"; when the
dowser walks over the water vein, they
either open out or cross each other. As
with any tool, the movement depends
on what the dowser expects.
The final tool, a pendulum, is not
quite as useful for finding water, but it is
perhaps the easiest tool for a beginner to
master. The dowser attributes a "yes,"
"no," and a neutral to each of the
pendulum's movements (back and forth,
clockwise and counterclockwise) and
uses it to answer simple yes-and-no
questions—such as whether the gallonper-
minute flow is 20 or 30, whether it
is worthwhile to divert a vein back into
an old
