ON page 43-44 of chapter 4 Dill has just arrived from Mississippi and the children are trying to decide what to play. Dill says that he "smells death" and the kids start talking about "hot steam." Jem explains the theory of how to avoid death by the "hot steam" while walking down a road at night, but Scout contradicts him and tells Dill not to believe him. The children decide to play roll the tire and Jem lets Scout go first. Ms. Lee writes from this point from Scout's point of view:
"Until it happened I did not realize that Jem was offended by my contradicting him on Hot Steams, and that he was patiently awaiting an opportunity to reward me. He did, by pushing the tire down the sidewalk with all the force in his body. Ground, sky and houses melted into a mad palette, my ears throbbed, I was suffocation. I could not put out my hands to stop, they were wedged between my chest and knees. I could only hope that Jem would outrun the tire and me, or that I would be stopped by a bump in the sidewalk. I heard him behind me, chasing and shouting."
In Chapter 4, Scout runs by the Radley house each day when she comes home from school. She is really afraid of what might be there. Finally, on the last day of school, Scout is with Jem and they are able to walk, instead of run, past the house. A little later, Jem conquers his fear of the Radley place when he goes into the yard to get a tire that rolled there accidently. Both Scout and Dill look on with awe while Jem retrieves the tire. Jem has shown he has matured and dealt with his childish fears while Scout has not yet mastered them.
