In this story Major de Spain's hunting camp is about "twenty miles" from Jefferson (192), deep enough into the old growth woods to bring the men who live there during hunting season close to the "bear and deer" they and their dogs love to hunt (184). It includes a kitchen (where Ad sleeps), a "shed room" (where Boon sleeps, 187), and the "porch" where Lion spends the last hours of his life (197).
The story does not say exactly what Major de Spain does for a living, but when Quentin goes to "his office" he notes the "expensive, unobtrusive clothes" which de Spain wears at work (198). His "secretary" works in a separate room (198). It seems likely that this office is on the Square.
On the day they hunt Old Ben, Uncle Ike places Quentin "on [a] stand" (191) in a "part of the bottom" he has never seen before (192). A hunting stand can be a platform attached to a tree, but in Faulkner's hunting stories it is more likely just to be a position where the hunter is supposed to remain, typically with his back against a tree, until the hunting horn blows everyone in.
Courthouse Square is the physical, political and social center of Yoknapatawpha. It appears frequently in Faulkner's Yoknapatawpha fictions. In this project we use the Square as the location for places in Jefferson that cannot be more specifically located; in this story, then, it provides the location from which Quentin is narrating the story.
