What chapter was it in, in the Catcher in the rye, where holden talks about wanting to be the catcher?

I looked through my book and its at the end of chapter 22. The last page, end. Its when he is talking to his sister Phoebe about watching kids playing the playground. It's the first time he sees his sister after he dropped out of school. It's after that that he sees his old teacher and then decides to hang out with his sister after school before he goes home. In my book its on page 156, it might be different on your page though. The quote starts, "I thought it was, 'If a body catch a body". It's also the beginning of the paragraph. Well good luck. I love this book but damn does it confuse me.
