How to pronounce 22°09′N? and What is "filthy roots"?

[japanjapan]

Dear teacher,
please read the following sentence: HongKong is located at 22°09′N to 22°34′N and 113°50′E to 114°26′E.
I want to know how to pronounce the symbols °and ′; is the former pronounced as degree? what is the latter then? Should I read N as north?
Please help. thanks a lot.
By the way, could you tell me what "Damn you, I'll pull your filthy roots out of the wall" means?
yours sincerely.

[JCrawf]

This would be spoken as: twenty-two degrees, nine minutes north

Sorry, but I can't help with the "pulling roots" question.

re: filthy roots

The quote comes from a Dorothy Parker short story, doesn't it? The narrator is talking to the telephone (as though the telephone could understand her).

When she says "I'll pull your filthy roots out", she's talking about tearing out the cable connecting the phone to the wall.

(I only know this because I Googled the quote.)
