	Inches or Feet?

	Good.

	???
	(to keep it to round numbers:
	Circ = pi * Diam = 3.14*1 inch = 3.14 inches
	Area = Circ * length = 3.14 inches * 8 inches =
	
	_25.12_ square inches.

	If i repeat the calculation for 8 FEET:
	Area =3.14 * (8 feet * 12 inches/ft) ==
	300 (odd) Sq INCHES
	)

	??
	Is the 150 the sum of all the 'rods'?

	It would be interesting to understand the apparent
	discrepancy in the numbers.

	If the rod are already at 6 to 8 FEET in damp soil,
	adding radials (buried) might be more of an
	improvement....
