Are there any symbols that are important to the text?

The author J.D Salinger uses many symbols to single out Holden as his own person and to try to get the audience to see him as different from the other characters in the book. Firstly the red hunting hat Holden buys in New York symbols how different he is from the rest which he stands out when he wears it. Holden feels very unique in the hat but it definitely singles him out as weird and very odd. The childhood memory of the red hunting hat shows how Holden is not matured in a adult and is still attached or hasn't got over it. Also an adult would specifically not wear one of these hats so it is also another hint.

The symbol of Allies baseball glove honours his brothers passing and how Holden admired his brother so much. The glove has poetry written in it which shows Allies intelligence and artistic nature, which Holden really did admire.

The Symbol of the ducks when Holden has questions for the cab driver shows his curiosity for wanting to know something a child might ask. That Holden is technically still showing child qualities even though he is an adult. This is also foreshadowing how just like the ducks go away for the winter and adapt to a new environment, so should Holden and adapt to society by not getting to comfortable with society. The ducks offer hope when they leave and eventually return in the summer time.
