In a large roaster or Dutch oven, combine wheat, water, bacon and onion. Combine remaining ingredients in a bowl and pour into pan with wheat. Cover and bake at 200° for 6 hours. Remove cover the last 1/2 hour of baking. Add a little boiling water if mixture becomes a little dry. Serve hot with steaming hot Boston brown bread. Makes 14 cups. Also check to be sure it's done; it may take a little longer cooking time.
