NITRATE SUPPLIES.
ENOUGH FOR 300 YEARS, CHEAPER METHODS DISCOVERED. A writer in tho "Daily Consular and Trade Reports" of tho United States observes that from 1830 until 1907 the nitrate fields of Peru and Chile produced 36,443,327 tons of nitrate, about two-thirds of which was produced during the last ten 'years. "Thero has been," says the writer,. "much said about tho exhaustion of tho nitrate mines or beds, but from the best information obtainable they are good for-two hundred or tlireo hundred years, even at double tho production, which is about 2,000,000 tons per year. Fully one-half the production has been net profit, but a new process has been added that will do for tho nitrate business what tho cyanide process did for the gold production. Heretofore from 9 to 10 per cent, has boon left in the waste, but with tho new process it is claimed that thero will . not be a loss of 2 per cent., and at a less cost of production than by tho old method. Even tho waste or tailings can bo worked with a great profit."
