Preheat oven to 300 degrees F (150 degrees C) and place the rack in the center of the oven. Butter, or spray with a vegetable oil spray, a 9 x 5 inch (23 x 12 cm) (8 cup) loaf pan, and line the bottom of the pan with parchment paper.

In a large bowl, whisk together the flour, baking soda, baking powder and salt. Stir in the brown sugar, walnuts, and dried fruits. Use your fingers to make sure that all the fruits and nuts have been coated with the flour mixture.

In a separate bowl, beat (with a wire whisk or an electric hand mixer) the eggs and vanilla until light colored and thick (this will take several minutes). Add the egg mixture to the fruit and nut mixture and mix until all the fruit and nut pieces are coated with the batter. Spread into the prepared pan, pressing to even it out.

Bake for about 60 to 75 minutes, or until the batter is golden brown and has pulled away from the sides of the pan. (If you find the loaf over browning, cover with aluminum foil.) Remove from oven and place on a wire rack to cool. When cool, lift the loaf from the pan. To store, cover with plastic wrap or aluminum foil. This loaf is best after being stored for a couple of days. Will keep for about 2 weeks at room temperature or for a couple of months in the refrigerator. Cut into small slices with a sharp knife.

Makes one - 9 x 5 inch (20 x 13 cm) loaf.
