Remove giblets and neck from turkey; reserve for other uses if desired. Rinse
turkey with cold water and pat dry.
Loosen skin from the turkey breast a bit not totally detaching. Place
rosemary and sage under skin then smooth skin over herbs and back into place.
Place apple celery and onion into the neck cavity. Place the turkey breast
side up on a rack in a shallow roasting pan and brush with melted butter. Cover
turkey loosely with a "tent" of aluminum foil.
Bake at 325 degrees until meat thermometer registers about 180 degrees. This
should take from 3 1/2 to 4 hours but begin checking after 3 hours. Remove
turkey and let stand 15 minutes before carving. Serve with gravy.
