Mr. and Mrs. Norman F. Wiss of Oaklawn road, Short Hills, have returned from Quantico, Va., where their son, Lt. Frederick Wiss, USMC, was commissioned last week. He accompanied his parents home for a few days' leave, after which he will report to Camp Pendleton, Cal. Mrs. Wiss Jr. of Greensboro, N.C., is visiting the Wisses before going to a girls' camp in Vermont later in the month as arts and crafts director. The Wisses will open their Avon home early in July for the remainder of the summer.
