"had his bunk in the harness room; a little shed that leaned off the wall of the barn. On one side of the little room there was a square four-paned window, and on the other, a narrow plank door leading into the barn. Crooks’ bunk was a long box filled with straw, on which his blankets were flung...scattered about the floor were a number of personal possessions; for, being alone, Crooks could leave his things about, and being a stable buck and a cripple, he was more permanent than the other men, and he had accumulated more possessions than he could carry on his back. 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 gets his own room because he's the only black man working on the farm. He has a lot of possessions because he stays in one place for a long time, he doesn't have to look for work too often. He keeps the room as clean as he can, and pretty neat. It also seems like he collects things that he won't necessarily need, but he still keeps them.
