The "Tennessee police" who close Jake Montgomery's roadhouse and "run him back across the Mississippi line" are presumably state police officers (113).
According to Sheriff Hampton, Jake Montgomery's Tennessee roadhouse was closed by the police after "a man went and got killed in it one night two-three years ago" (112-13).
The hypothetical "expert that can tell about bullets" (71), "somebody from the Memphis police" (188), that Chick assumes several times Sheriff Hampton will have to call in. Though in a different state, Memphis is the closest large city to Yoknapatawpha.
Chick reminds his uncle Gavin what he once told him, "about the English boys not much older than me leading troops and flying scout aeroplanes in France in 1918" (200). It is noteworthy that neither of them refers to soldiers in the more contemporary Second World War.
"The counterman" at Jefferson's all-night cafe is mentioned only briefly, and neither named nor described (207). Because Faulkner makes no mention of his race, we assume he is white.
Jefferson has two marshals, who keep order in town. The night marshal is referred to only as the "nocturnal counterpart" of Willy Ingrum, the day marshal (206). To make sure residents can reach him, his office telephone is "connected to a big burglar alarm bell on the outside wall" (207).
On their way to the Edmonds place in the morning of "the first winter cold-snap" (4), Chick and Aleck Sander pass small farms where everyone seems to be involved in the same two activities. The women, wearing "sunbonnets" or "men's old felt hats," are boiling water in big kettles, while the men, "with crokersack aprons tied with wire over their overalls," prepare to slaughter hogs (4). (A croker sack is a burlap bag.)
