BORAX*4I 'Where Thin Coinuolt;llly 1* Produced -AnfaexhutifitJbli* Nupply.The price of commercial borax has greatly decreased during the past thro'-yearn. It can be bought now for half what it cost in ld62. Then the market r;t . .. a pound,the present time it is live anil a ...iff cents a pound. This falling off in prices has continued notwithstanding tho imposition of a tariff which virtually prohibits the importation of borax ami boracic acid. It has been due, therefore, to the consumption not keeping up with the supply. The production of borax on the Pacific coast, which is the only part of this country where it is found, has been steadily very largo. Last year four thousand live bum I red tons were extracted by the various mining companies in this State ami Nevada. Its use has not grown more limited, but it has not kept pace with the production. It is employed in welding, glazing, pottery and cleansing. The iron trade consume* th« largest quantity of borax, and with the increase of that industry tho business of borax-mining will tic benefited. New uses are being found for this mineral. At first it was thought fit out; jor iron-worKers ana ojacksmiths. Its detersive qualities were revealed afterward. The manufacture of glazed iron and earthenware was begun after other virtues were discovered in borax, and now it is employed in packing meats in Chicago. Notwithstanding the supply from Italy, largo quantities of borax are exported to Ku-rope from the Pacific coamL Last week seven hundred and seventy-live thousand pounds were shipped from this port to Liverpool. Some of the London illustrated papers contained flaming advertisements, in true Amor, can style, lauding tho virtues of soaps made from California borax. Boracic soaps and borax in the* shape it comes from the mines an* admirable cleansers. A piece of borax dropped into water renders it pleasant to wash in. The supply on th*s coast is practically inexhaustible, as when crude borax is removed from the fields where it is found h renewal of ft onsiu s. So important is this indutrv h**re that .Sack-ville West, the Kngl sh M nister, recently made it the -vibcct of a communication to Karl Granville. Mott d the mineral deposits of this region carry borax in ?. crude form, and consequently there an* many borates from which the pure borax «s obtained. Tho crude borax of this c'wtst is of a high quality. The largi st supply comes from T'-el Marsh, in the Candelaria dis-crict. Nevada. This field ha* been worked the longest and has given the greatest yield of any on the coasf. There is a big marsh, twelve miles long, in San Bernardino, and several in Mo*«o, Lake and otnrr counties. The der ossion now existing in the bon x o will, it is thought, gradually \+* moved. — .San Vrn?nn#ro ('hrnn^u
