He knew that colored children were not supposed to defy white people in that part of the country.

When the uncle reached the spot where the child was standing, she quickly stepped forward one step, looked up into his eyes, and screamed at the top of her shrill voice, "MY MAMMY'S GOTTA HAVE THAT FIFTY CENTS!"

The uncle stopped, looked at her for a minute, then slowly laid the barrel stave on the floor, put his hand in his pocket, took out half a dollar, and gave it to her.
