Quote from : Reading the Waste Land: Modernism and the Limits of Interpretation Book

The Stetson passage is an allusion to Frazer theory in The Golden Bough that religion originated as agricultural engineering. Through a grotesque process of literalization, all of the dying gods and heroes in The Golden Bough, along with Christ and the Fisher King, are transferred from mythic to modern consciousness ( Frazer himself was an unabashed positivist) to be made explicable in scientific terms as fertilizer.
