This is the "somebody at the City Hall" who is informed about the missing brass fixtures at the power plant and calls in "the auditors" to investigate the matter (31).
Otis is "nephew or cousin or something" of the Harker who is the engineer at the town's power plant. Although he has "inherited the saw mill" that the older Harker originally ran, Otis fills in at the power plant "whenever Mr. Harker wanted a night off" (26). By the end of the novel he has become Jefferson's "night marshal"; Gavin Stevens calls him one of Yoknapatawpha's "minor clowns" (334).
He is the Jefferson marshal and father of Buck Connors II. (His name is spelled "Conner" in "Centaur in Brass" and Light in August, and he is probably also the "Buck" who appears in Flags in the Dust.)
The two men "in spectacles" who audit the accounts of the Jefferson power plant are presumably employed by the state, or perhaps by the company that bonds local officials (22). According to Mr. Harker, "They went over the books and poked around ever where, counting ever thing in sight and writing it down" (22).

Bryan Ewell is a deputy sheriff whom the sheriff orders to guard Wesley Pritchel's house after Pritchel has locked himself in his room (122). (Bryan may be related to Walter Ewell, who appears in six other fictions, but there is no mention of any relationship.)

A group of "archaeologists from the State University" dig up Native American relics from Pritchel's clay pit until he runs them off with a shotgun (119).
When Provine leaves camp to go to the mound, he travels down "the road that went down the bottom" (72). Given the fact that the woods in the story are called a "jungle of cane and gum and pin oak" (65), this "road" is probably more like a path.
