Cookie - Refrigerator Date Pinwheels

2 1/4 cup chopped pitted dates                      2 cups brown sugar
1 cup sugar                                                    3 eggs (well beaten)
1 cup water                                                    4 cups flour
1 cup chopped nutmeats                                 1/2 tsp salt
1 cup butter                                                   1/2 tsp baking soda

Combine the dates, sugar, and water in a saucepan, and cook over low heat until thick, about 10 mins.  Add the nutmeats; cool.  Meanwhile cream the butter and brown sugar.  Add the well-beaten eggs and beat well.  Add the remaining ingredients and mix well.  Chill thoroughly.  Divide the mixture into two parts, and roll each out separately int a rectangle a little less than 1/4" thick.  Spread each with some of the date filling, and roll up as for a jelly roll into two long rolls.  Chill thoroughly - overnight if you can.  Then cut with a sharp knife into slices about 1/4" thick.  Bake at 400 degrees for 10 - 12 minutes.  Makes about 5 doz cookies.
