Explanation:
In Caroline Henderson letter to Henry A. Wallace in 1935, she mentions about changes that were happening in Oklahoma during the 1910s and 1920s. According to her, people began expanding in the area which causes more towns to spring up, along with trains and easier access to land, and food. Henderson wrote this letter to explain the once fertile land turned into an awful dust storm with no food.
