1. The ratio of (1) the weight of water which the soil, after saturation,
will retain against a centrifugal force 1,000 times the force of gravity,
to (2) the weight of the soil when dry
2. The number of gallons of water a day, at 60 deg. F., that is conducted
laterally through each mile of the water-bearing bed under investigation
(measured at right angles to the direction of flow) for each foot of
thickness of the bed, and for each foot
