Sift dry ingredients together.
In a large mixing bowl, cream butter and sugars. Add eggs one at a time, beating well after each addition; stir in vanilla. Combine nuts and fruits with the flour mixture; stir into the creamed mixture. Form dough into rolls; chill thoroughly* (may be frozen for future use). Cut into 1/8- to 1/4-inch slices; bake at 325° for 10 to 12 minutes.
* Cookie rolls slice better if partially frozen.
Makes about 8 dozen cookies.
