How does Cormac McCarthy use imagery in Outer Dark?

Imagery:

"Above the odor of sweat and manure he could smell the musty decay of the boxes. When he came abreast of the wagon he could see a waxen gray face scowling eyelessly at the bright noon. In the next box lay what appeared to have an old man."

"They don't nobody live there now. Used to be a mink-trapper lived there but he got snakebit and died. When they found him he was kneelin down like somebody fixin to pray. Stiff as a locust post. . . They said they had to break ever bone in his body to get him laid out in his box."
