Which detail helps describe the primary setting of the story?

There is not any one detail that adequately describes the setting. The story is set in and around a small home in the rural south during the 1930s and we know this over the course of reading the story.

There is not any one detail that adequately describes the setting. The story is set in and around a small home in the rural south during the 1930s and we know this over the course of reading the story. 

If we had to choose a passage full of detail that adequately captures some of the setting, we might begin with the first paragraph. In it we are introduced to the kitchen which will appear many other times in the story, and which is the centerpiece of many of the main characters' interactions. 

"Imagine a morning in late November. A coming of winter morning more than twenty years ago. Consider the kitchen of a spreading old house in a country town. A great black stove is its main feature; but there is also big round table and a fireplace with two rocking chairs placed in front of it. Just today the fireplace commenced its seasonal roar" (Capote).

This sets up a cozy, welcoming, and rustic setting. The details in this paragraph that tell us this are the large round table (think big family gathering spot), the large roaring fireplace (warm and cozy) and the two rocking chairs (they can spend time sitting in front of the fire!). The setting is familial and warm.
