Preheat oven to 350. Grease a 9 by 5 inch loaf pan. Line bottom and along sides of pan with waxed paper. Allow 3 inches overhang of paper at top. Sift flour, sugar, baking powder and salt together in a large bowl. Cut in butter until mixture resembles coarse meal. Remove 1/2 cup flour mixture to medium bowl and set aside. Stir eggs, milk , vanilla and almond extracts into original flour mixture. And beat until blended. Pour about 1 cup batter into prepared pan. Add almonds, cinnamon, and allspice to reserved flour mixture and stir well. Sprinkle 1/3 of the nut mixture over batter in pan. Repeat layering twice, ending with nut mixture. Bake until toothpick inserted in center comes out clean, about 70-80 minutes. Loosen sides of loaf pan with wide spatula. Grasping waxed paper firmly, pull loaf from pan and cool on wire rack.
