Preheat the oven to 375 degrees F, and grease 3 medium (8 1/2 X 4 1/2) loaf pans, sprinkling a little brown sugar in each. Combine all the dry ingredients in a large bowl and fashion a well in the center. Break in the 4 eggs and add the salad oil, water and pumpkin. Beat thoroughly until well mixed, then add the raisins and nuts. Pour into the prepared pans. Bake 1 hour and 15 minutes or until a cake tester or wooden pick inserted in the center comes out clean. Cool for 5 minutes in the pans before turning onto wire racks to cool.
NOTE: This bread can be wrapped in aluminum foil and frozen very satisfactorily.
