Robert+Burns+-+Comin'+Through+the+Rye

Coming thro' the rye, poor body, Coming thro' the rye, She draiglet a' her petticoatie Coming thro' the rye.

O, Jenny's a' wat, poor body; Jenny's seldom dry; She draiglet a' her petticoatie Coming thro' the rye.

Gin a body meet a body Coming thro' the rye, Gin a body kiss a body - Need a body cry?

Gin a body meet a body Coming thro' the glen, Gin a body kiss a body - Need the warld ken?

Holden wants to be "the catcher in the rye" to save the kids from falling, and the first one he wants to save is Phoebe, his sister. Not to save them from dying like his little brother, but for them not being swallowed and changed by the world when growing up. Basically, he doesn't want them to become "phonies", he would rather die than see Phoebe changed by the interaction with all the stupidity that is waiting for her out there, and in his mind he extends that to other kids.
 * Meaning on catching**

First of all, "rie" is not "rye" as in the grain but is actually translated in modern english to "river". So when it says that Jenny is always wet, it means that she is always running straight back into the river, the river being life. The poem is about love, not sex. Its about being free in the world, and the idea that risking everything is worth finding love. In relation to "Catcher in the Rye" while Holden does originally misinterpret the meaning of the poem, it does contain the main gist of the book. Holden originally interprets the poem in his dream, and believes that he will save all the little children about to fall off the cliff. However, in his epiphany as he watches Phoebe ride the carousel and try to grab the golden ring he realizes that the little children need to fall and that its a good thing. Everyone needs to learn. And this is also the meaning of the poem, experience and be free. Your life is your own, live and love as you will.
