““‘GREEN DUSK FOR DREAMING BRAND PURE NORTHERN AIR,’” he read. “‘Derived from the atmosphere of the white Arctic in the spring of 1900, and mixed with the wind from the Hudson Valley in the month of April, 1910, and containing particles of dust seen shining in the sunset of one day in the meadows around Grinnell, Iowa, when a cool air rose to be captured from a lake and a little creek and a natural spring.’””

—Ray Bradbury, from Dandelion Wine, 1953.
