"It was a long head, bony, tight of skin, and set on a neck as stringy and muscular as a celery stalk. His eyes were heavy and protruding. The lids stretched to cover them and the lids were raw and red. His cheeks were brown and shiny and hairless, and his mouth full, humorous, or sensual. The nose, beaked and hard, stretched the bridge so tightly that the bridge showed white. There was no perspiration on the face, not even on the tall, pale forehead. It was an abnormally high forehead lined with delicate blue veins at the temples. Fully, half of the face was above the eyes. His stiff grey hair was mussed back from his brow as if he had combed it back with his fingers. For clothes he word overalls and a blue shirt. A denim coat with brass buttons and a spotted brown hat creased like a pork pie lay on the ground beside him. Canvas sneakers, grey with dust, lay nearby where they had fallen when they were kicked off. The man looked long at Joad. The light seemed to go far into his brown eyes, and it picked out little golden specks deep in the irises. A strained bundle of neck muscles stood out."
(Chapter 4)
Compare the above description to that of the turtle from Chapter 3...
"And over the grass at a roadside a land turtle crawled, turning aside for nothing, dragging his high-domed shell over the grass. His hard legs and yellow-nailed feet threshed slowly through the grass, not really walking, but boosting and dragging his shell along. The barley beards slid off his shell, and the clover burrs fell on him and rolled to the ground. His horny beak was partly open, and his fierce, humorous eyes under brows like fingernails, stared straight ahead. [...] the horny head potruded as far as the neck could stretch."
(Ch. 3, pp. 14-15)

"The hell with it! There ain't no sin and there ain't no virtue. There's just stuff people do. It's all part of the same thing and some of the things people do is nice and some ain't nice, but that's as far as any man got a right to say."

"I figured about the holy sperit and the Jesus road. I figured, why do we have to hang it on God or Jesus? Maybe, if figgered, maybe, it's all men and all women we love. Maybe that's the holy sperit. The human sperit. The whole shebang. Maybe all men got one big soul everybody's a part of. I sat there thinkin' it, and, all of the suddint, I knew it. I knew it so deep down that it was true, and I still know it."

The preacher leaned forward and the yellow lantern light fell on his high pale forehead. "IJail house is a kinda funny place," he said. "Here's me, been a-goin' into the wilderness like Jesus to try find out somepin. Almost got her sometimes, too. But it's in the jail house I really got her." His eyes were sharp and merry. "Great big ol' cell, an' she's full all the time. New guys come in, and guys go out. An' 'course I talked to all of 'em."

Casy grinned. "Well, sir," he went on, "I begin gettin' at things. Some a them fellas in the tank was drunks, but mostly they was there 'cause they stole stuff; an' mostly it was stuff they needed an' couldn' get no other way. Ya see?" he asked.
"No," said Tom.
"Well, they was nice fellas, ya see. What made 'em bad was they needed stuf. An' I begin to see, then. It's need that makes all the trouble. I ain't got it worked out. Well, one day they give us some beans that was sour. One fella started yellin', an' nothin' happened. He yelled his head off. Trusty come along an' looked in an' went on. Then another fella yelled. Well, sir, then we all got yellin'. And we all got the same tone, an' I tell ya, it jus' seemed like that tank bulged an' give and swelled up. By God! Then somepin happened! They came a-runnin', and they give us some other stuff to eat--give it to us. Ya see?"
"No," said Tom.
Casy put his chin down on his hands. "Maybe I can't tell you," he said. "Maybe you got to find out."

Casy stared blindly at the light. He breathed heavily. "Listen," he said. "You fellas don' know what you're doin'. You're helpin' to starve kids."
"Shut up, you red son-of-a-bitch."
A short heavy man stepped into the light. He carried a new white pick handle.
Casy went on, "You don' know what you're a-doin'."
The heavy man swung with the pick handle. Casy dodged down into the swing. The heavy club crashed into the side of his head with a dull crunch of bone, and Casy fell sideways out of the light.
Tom looked down at the preacher. The light crossed the heavy man's legs and the white new pick handle.
