Mrs. Katherine McKinnon Cornelius, of Lake Worth, Fla., 23, mother of a baby daughter and a professional for about two years, and Miss Barbara McIntire, of Toledo, Ohio, 21 and an amateur and college student, tied with scores of 302 for 72 holes. Mrs. Cornelius won in a playoff, scoring 75 to Miss McIntire's 82, at the Northland Country Club, Duluth, Minn.

Miss McIntire, finishing early on the last day, closed with a fine 71, playing the last three holes in birdie-par-eagle. Mrs. Cornelius and Mrs. Marlene Bauer Hagge, playing together behind her, fought a close duel which Mrs. Cornelius won by getting gown in two on the last green to tie Miss McIntire while Mrs. Hagge was taking ghree from a difficult position.

Mrs. Cornelius' rounds were 73-77-73-79. The entry of 46 was divided almost evenly between professionals and amateurs. Again Mrs. George Zaharias was too ill to compete. The prize money was reduced to $6,000, Mrs. Cornelius receiving $1,500.
