Show FRESH WATER FROM OCEAN All Seaboard Cities May Be Abundantly Abund-antly Supplied by Springs. Suggestion of great possibilities of fresh water supply is given In a paper iv Prof, C H. Hitchcock of Dartmouth college. It Is a study of fresh water springs in the ocean and within a few miles of the shore. Enough is known of tho existence of such springs to warrant the belief tnat there must be vast quantities quan-tities of fresh water discharged in this way through undiscovered springs, and perhaps close to big cities and to fertile soil whers the water is needed for drinking drink-ing or for Irrigation. Some of theie springs show arte-slun conditions and will rl6e thirty-two to forty-two feet by the pressure of the supply There Is a porous water-bea ring Stratum beneath an Impervious Im-pervious eovei Piercing this by boring gives access to a water supply that will rise ejulte. u he-lcht Without pumping. One of the most notable examples of this condition Is at the Island Of Oahu Th plantations on this island have made valuable use of the water for irrigation purposes. On one plantation EOOO acres are so Irrigated Though the pumps work continuous!) the water never fails Close to the coast line no pumps are needed, as the water rlcs twi nty-two feet. At Honolulu Hono-lulu such water will rise forty-two feet At Oahu they reach this water-bearing stratum by boring 300 to 400 feet Some of these springs well up so powerfully as to prevent the ocean water from commingling com-mingling with the fresh In cases where the artesian water finds its own outlet through a crevice In the impervious strata. Powerful streams are said to discharge dis-charge millions of gallons of water through artificial openings very near the Seashore. These are believed to continue some distant Ill tO BBS and then to well Up mingled with the oceun billows Prof. Joseph Le onte In his "Geology" mentions tho existence of fresh water springs rising ln the ocean near Hawaii. Around the Florida coast there Is much of this water, and at many places it Is bored for and utilized. The wonderful Silver spring, which bursts B full-grown navigable river Immediately from Its source. Is given as an example of the underground un-derground spring. It Is the rainfall of a region far awuy, perhaps, and the water filtered through miles of sand Bliss Re-dun Re-dun the gr at geographer, tpeaks of such j springs existing east of the Isle of Pines. I All this suggests the possibility that In I the future many big seaboard cities may discover that they can obtain an abundant abund-ant supply of pure drinking water almost at their doors by searching under the ocean for what Is now going to waste and mlxliu; with the brine. It certainly stands to reason that If so many outbursts out-bursts of fresh water In the sea are already al-ready known there must be others yet to be discovered. |
