The chief experiments of the day were still to come off.  We saw a number of buoys floating in various directions some way up the harbour. A launch advanced towards one, when the buoy being struck by the pole, the charge of a torpedo some twenty yards away was ignited, and the fearful engine exploding, lifted a huge mass of water some thirty or forty yards into the air.  How terrible must be the effects when such a machine explodes under a ship!  As soon as the torpedoes had exploded, the boats pulled up to the spot, and picked up a large number of fish which had been killed or stunned by the concussion--for many did not appear to be injured, and some even recovered when in the boats.
