Joad settled himself on the clean sand. "I ain’t gonna sleep in no cave," he said. "I’m gonna sleep right here." He rolled his coat and put it under his head. Muley pulled at the covering brush and crawled into his cave. "I like it in here," he called. "I feel like nobody can come at me."
…"I ain’t sleepin," said Casy. "I got too much to puzzle with." He drew up his feet and clasped his legs. He threw back his head and looked at the sharp stars. Joad yawned and brought one hand back under his head. They were silent, and gradually the skittering life of the ground, of holes and burrows, of the brush, began again; the gophers moved, and the rabbits crept to green things, the mice scampered over clods, and the winged hunters moved soundlessly overhead.
