Step-by-step explanation:
In the poem Blue Racer by Julie Heller, the word brush means grass, sticks, and fallen leaves. The setting of the poem is that of a father and his child taking a walk in the woods.
As they walk, the man has a stick which he might have been using to find his way around the shrubs, leaves and sticks in the woods. It was while doing this that he unknowingly touched a Blue Racer snake with his stick. He told his child that the Blue Racer was known for running very fast. This made the child to begin running across the woods while her father called out to her.
