Setting default font

[John Smith]

I am using emacs 21 under X-Windows, and the default font for text is 
rather small. I can change this under the Options/Mule menu. I select my 
preferred font -- courier 14 -- and then try to Save these settings 
(under the same Options menu). But the save doesn't save. The next time 
I start up, I get the same microscopic font. Any suggestions? I would 
think there's some line like set-default-font-courier 14 that I can put 
in my .emacs file.
