"Beware the autumn people"
Mr. Halloway recalls “an old religious tract” by Pastor Newgate Phillips in which he warns the listener against “the autumn people,” who “sift the human storm for souls, eat flesh of reason, fill tombs with sinners.” I have not been able to find any record of Pastor Phillips or the pamphlet, and have concluded that Bradbury made it up. The Autumn People became the title for a collection of EC comic book adaptations of eight Bradbury short stories, illustrated by Alfred Feldstein and published in 1965.

Also, compare Mr. Halloway’s speech with the introduction to The October Country, in which Bradbury quotes his grandfather about “the October people,” who are conceived in the autumn of one year and born in the autumn of the next”; when “it’s always a dark season” and they “smell of burnt leaves.”
