MINERAL CONTENT OF GROUND WATERS IN SAN JOAQUIN VALLEY. (NCREASE OF \il\i.i;\! CONTENT FROM SOUTH TO NORTH. J 21 as much tninera) matter; and the waters that were bested from wellsmore than i.ioo teet deep in Sao Joaquin County average 5,200 partsper million in mineral content.. These data indicate a decided north-ward increase beginning in Fresno County in the mineral content ofthe deep waters, a conclusion that is corroborated by the few availabletests of deep ground waters in the axis. Tho 2,250-foot well in sec.14, T. IS S., 11. IS E., included among the axial waters, yields poorwater, and the 1,200-foot well at French Camp furnishes a supplycomparable with the deep waters at Stockton. OCCLUSION OF SEA WATER. Though it has been suggested that this increase of solids, represent-ing increase of chloride and alkali, is evidence of the occlusion of seawater within the deep sediments, the composition of the waters makesthis improbable. Sea water contains 33,000 to 37,000 parts per mil-
