This method is believed to save 50 or CO per cent, of gold usually left in the stone which has gone through the grinding operation with machines such as Wheeler's, or Berdan's ofParis, or of Arrastra's. The process is a cheap one, and ought to greatly increase the production of gold in New Zealand.
