 ingredients together, except nuts.  Place over cream cheese mixture.  Sprinkle
 chopped nuts on top. Bake for 10 minutes.  Lower heat to 400 degrees F and
 bake for 25 minutes.  Do not remove ring until cake has set overnight and is
 well together.  Run knife around side of springform pan while cake is cooling.
