Indian Agency in "A Name for the City" (Location)

Before Jefferson had a name, before it was even a village, it was a "Chickasaw agency trading post" - a place where the indigenous population of the region interacted with an agent appointed to represent the federal government in its dealings with them (200). The story describes this building as a "post-office-trading-post-store" which contains at least two rooms, including the "back room" where the agency records were stored (202). It's likely that the agent also lived there.
