man chmod:

        The letters ‘rwxXstugo’ select the new  permissions  for  the
        affected users:  read  (r),  write (w), execute (or access for
        directories) (x), execute only if the file is a directory or
        already has execute  permission  for  some user (X)

amd thus:

chmod -R u=rwX,g=rX,o=rX dir/

`find' is great, but in this case there's an easier way, and one that'll 
be a fair whack faster.
