From Fitzgerald's "The Beautiful and Damned"

He was reminded of a fantastic romance he had lately read in which cities had been bombed from aerial trains, and for a moment he fancied that Washington Square had declared war on Central Park and that this was a north-bound menace loaded with battle and sudden death. But as it passed the illusion faded; it diminished to the faintest of drums - then to a far-away droning eagle.
