Spreadin' sin

Uncle John scratched the earth deeply with a long rusty nail. "He knowed about sin. I ast him about sin, an' he tol' me; but i don't know if he's right. He says a fella's sinned if he thinks he's sinned." Uncle John's eyes were tired and sad. "I been secret all my days," he said. "I done things i never tol' about."
Ma turned from the fire. "Don' go tellin', John," she said. "Tell 'em to God. Don' go burdenin' other people with your sins. That ain't decent."
"They're a-eatin' on me," said John.
"Well, don' tell 'em. Go down the river an' stick your head under an' whisper 'em in the stream."
Pa nodded his head slowly at Ma's words."She's right," he said. "It gives a fella relief to tell, but it jus' spreads out his sin."
Uncle John looked up to the sun-gold mountains, and the mountains were reflected in his eyes. "I wisht I could run it down," he said. "But I can't. She's a-bitin' in my guts."

Overall I didn't mind the book, however the dialogue style/spelling really gave me the shits. And the third person, situational chapters of scenes that would have taken place during the great depression, mostly painting an anti-capitalist picture also gave me the shits (again, more the style, rather than the content). Otherwise he's a brilliant writer.
