1. Grease and line three 8-in. x 4-in. loaf pans with waxed paper; set aside. In a large bowl, combine dates, nuts and cherries. Combine the flour, sugar, baking powder and salt; stir into fruit mixture until well coated. In a bowl, beat eggs and vanilla until foamy. Fold into fruit mixture and mix well. Pour into prepared pans.
2. Bake at 300° for 1 hour or until a toothpick inserted near the center comes out clean. Cool for 10 minutes before removing from pans to wire racks. Remove waxed paper. Cool completely before slicing. Wrap and store in a cool dry place. Yield: 3 loaves.
