Methods by which subterranean supplies of water may be made more available:- The water-bearing strata of the earth's crust may be broadly divided into three classes.- (1) Hard metamorphic rocks with fissures and cracks in them. (2) Stratified beds of rocks of varying degrees of porosity (3) massive or stratified deposits of sand or gravel. The conditions of yield from the bores sunk into these strata vary with their nature and consequently the methods by means of which the yields may be augmented will differ accordingly.
