Chapter 4 begins with a description of Crooks' bunk in the harness room, a description that reveals quite a bit about Crooks character.
Crooks possessed several pairs of shoes, a pair of rubber boots, a big alarm clock and a single-barreled shotgun. And he had books, too; a tattered dictionary and a mauled copy of the California civil code for 1905. There were battered magazines and a few dirty books on a special shelf over his bunk. A pair of large gold-rimmed spectacles hung from a nail on the wall above his bed.
This room was swept and fairly neat, for Crooks was a proud, aloof man. He kept his distance and demanded that other people keep theirs. His body was bent over to the left by his crooked spine, and his eyes lay deep in his head, and because of their depth seemed to glitter with intensity. His lean face was lined with deep black wrinkles, and he had thin, pain-tightened lips which were lighter than his face.
