A NEW EXPLOSIVE.
Mr R. A. M'Arthur, expert for the Rand Drill and Rackarock Company, gave a public exhibition of the explosive at Mr Calder's quarry, North-east Valley, this afternoon. The explosive is made up of two ingredients—one a liquid (an extract of coal tar), and the other a solid (chlorate of potash). The absorbent ia made up in cartridges, and ia dipped in the liquid for a few seconds before it is used. The ingredients are kept separate, are entirely free of nitroglycerine, and are united only when required for immediate use. The patent is an American one, but the factory is now situate at Sydney, while the head office is at Melbourne, an Australian company having bought the sole right of the patent. Several cartridges were exploded this afternoon, and. in each case a large mass of rock was displaced, although the pieces were not; thrown far. Altogether the trial was a. success.
