	Put two earth conductors into the ground and measure the resistance between
them.  Consider the resistance to be combined resistance of two series
resistors.
	You may be dissapointed!  I have four 8 foot ground rods here
which were installed to provide ground for 50 foot vertical antenna.
Soil is dry, sandy, and rocky.  Even after much watering around the
holes they measure
			800 OHMS BETWEEN RODS!!!!!!!!!!
2" copper water main from street works much better.
