Seminary ridge is named for the "Seminary" that is located there. Charles Mallison calls it "a college" at the end of the novel (367), but it's not clear exactly what that means in this context. Melisandre Backus and Maggie Mallison both go there after high school (52), so it is probably best understood as a finishing school.
The Mississippi State Insane Asylum was located in Jackson until 1935. This is "the asylum" that Mink's lawyer argues his client should be sent, instead of prison (51). It is also "the asylum" where Benjy Compson have been committed for a number of years, until his mother convinces Jason to bring him back home (354).
To get to Jefferson in Light in August the Hineses take the "2 a.m." northbound train at this station to reach Jefferson; as they wait for it in the waiting room, the "drummers and loafers and such" come in and buy tickets for the 9 p.m. "southbound" (359).
During his attempt to explain to Roth why he is renouncing the McCaslin inheritance in Section 4 of "The Bear," Ike refers several times to the Bible, which Ike calls "the Book" (243), and what "He told" in that text. Some of his phrasings bring that scriptural landscape into physical focus, for example "how He created the earth, made it and looked at it and said it was all right" (243).
This spring "that flows from the roots of a beech" in the woods behind the Sartoris plantation is where, after the Union troop chases Colonel John away, his son Bayard has an epiphany. While the sound of the soldiers' horses grows fainter and the "final light of the day" shines on his face, Bayard looks at his reflection in the spring and sees, "staring back at him for a sudden moment, a skull" (91). It could be a premonition of his death, or of the much more imminent 'death' of the Confederacy and the Old South - or both.
As in other texts, such as The Town, "Mexico" in this novel is associated with lawlessness. Ratliff speculates that after Montgomery Ward Snopes falls afoul of the law, his cousin Flem Snopes will ship him off "to Mexico or wherever" (69).
At the bottom of the pasture on the Sartoris place runs a creek that appears in a dozen other fictions, though the role it plays in this story connects it thematically to another creek, the one on the Compson place in The Sound and the Fury where Caddy Compson lies: it's where Narcissa goes to symbolically wash away her shame for having sex with the F.B.I. agent in Memphis.
It seems that Faulkner couldn't decide what was produced at the Frenchman's Bend mill owned by Will Varner. It is referred to in three different texts. In two of them - "By the People" and The Mansion - it's "Uncle Bill Varner's water mill" (347), and the site of "the annual Varner's Mill picnic," a social event at which local politicians announce their candidacies (88, 326). In the other, The Town, it's "Uncle Billy Varner's saw mill" (33), and the site of an industrial accident that cripples Eck Snopes.
During his years out west Jack Houston works for a while as "a longshoreman on the Galveston docks"; in "a Galveston brothel" he meets the woman with whom he lives in Galveston and El Paso as in a common law marriage (234).
