The Carousel
The Carousel 
 
This is a symbol because the carousel goes around and around. It never goes anywhere. It is a symbol of his stagnation in childhood. Holden, who would like nothing to change and everything to stay the same, now accepts that this is a childish dream. At the end of the story Holden does not choose to get on. He lets Phoebe go on and he is comfortable with this decision.
