White swan of cities slumbering in thy nest . . . White phantom city, whose untrodden streets Are rivers, and whose pavements are the shifting Shadows of the palaces and strips of sky.
Henry Wadsworth LongfellowShips that pass in the night, and speak each other in passing, only a signal shown, and a distant voice in the darkness; So on the ocean of life, we pass and speak one another, only a look and a voice, then darkness again and a silence.
Henry Wadsworth Longfellow
