boom of guns and crash of bursting shells ceased as suddenly as it began. Kennedy turned his glasses on the fleet and saw a couple of hydro-aëroplanes lifted by cranes from the deck of an auxiliary ship and placed in the water. They rose as they advanced on the city, over which they flew at an altitude of 1,500 feet. One of them swung off at the Battery and began to fly in a circular path. The other passed on until it reached the Fifty-ninth Street power station of the Subway, above which it began to describe a path of the figure eight. Kennedy turned his glasses upon the fleet. One of the guns in No. 1 turret of the flagship was being slowly elevated until it pointed well into the sky. There was a flash—a long, droning hum—and thirty seconds later he saw the shell burst against a building north of the power station. From the hydro-aëroplane above there was dropped a puff of white smoke.
