This entry represents the men - described simply as "a few more men" - who watch the fight that Buddy McCallum arranges between his son Anse and Matt Levitt (207). Since Matt is from town and Anse from the country, these men could be from anywhere in Yoknapatawpha.
"The lot behind I.O. Snopes' mule barn" is where he pastures the mules he buys in Memphis (253). It is also where Buddy McCallum takes Matt Levitt and Anse McCallum to fight it out after he bails them out of jail.
