The Red Pony
They turned and walked slowly down the hill toward the barn. Jody was tortured with a thing he had to say, although he didn't want to. "Billy," he began miserably, "Billy, you won't let anything happen to the colt, will you?"
And Billy knew he was thinking of the red pony, Gabilan, and how it had died of strangles. Billy knew he had been infallible before that, and now he was capable of failure. (3.91-3.92)
Sometimes in the night the ranch people, safe in their beds, heard a roar of hoofs go by. They said, "It's Jody, on Demon. He's helping the sheriff again." (3.97)
The mare turned her head and looked full into his eyes for a moment, and this is a thing horses practically never do. Billy was proud and sure of himself now. He boasted a little. "I'll see you get a good colt. I'll start you right. And if you do like I say, you'll have the best horse in the county."
That made Jody feel warm and proud, too; so proud that when he went back to the house he bowed his legs and swayed his shoulders as horsemen do. (3.119-3.120)
