Little Belle is at a "house party" somewhere when Horace calls her at the end of the novel (299), with someone whom readers only hear, as a "masculine voice" who interrupts Belle to try to tell Horace something before Belle "hushes" him (300).
These "drummers" don't actually appear in the novel, but we know they exist because the "old man" who picks them up in his taxi when they come to town on the train apparently tells them all the epigram that he has come up with to tell the story of his life (297). In Faulkner's time (and in his world), a "drummer" is a traveling salesman.
