How does Zora Neale Hurston use imagery in Spunk?

Hurtston uses a variety of imagery and dialogue to illustrate the concept of fear.

One of the men says of Spunk, "I'm skeered of dat man when he gits hot." Elijah hesitates to sit with Spunk's dead body because "Ah'm a li'l bit skittish." One of the men who comes to view the body is Joe's father, "who a few hours before would have been afraid to come within ten feet" of Spunk. None of these men has the courage Joe has finally found. As Walter puts it, "Joe's ready for Spunk an' ain't skeered any more."
