Olympic calibre swimming will come to Harvard Saturday to visit but not to stay.

The M.I.T. Swim Club is presenting an Olympic exhibition Saturday at the Indoor Athletic Building. Profits will help finance the 1968 U.S. Olympic swimming and diving teams. The three-act show will feature performances by some of the top swimmers and divers in America.

The first act will be diving and aquatic clowning by Dick Kimball and Ronnie O'Brien. Kimball, a professional diver, coached the U.S. Olympic diving team in 1964. O'Brien, who has been called the world's top water clown, is a three time All-American diver and coach of the American diving team for the 1967 Pan-American games.

The second act will star five of Yale's Ivy League Champion swim team. Leading the Bulldog swimmers will be Steve Clark, the world's fastest freestyle sprinter. Clark holds records in both the 50 and 100 yard freestyle events.

Mickey King. 1967 A.A.U. women's one and three meter diving champion, will give the third and final exhibition. She is considered the leading contender for the gold medal in women's one meter diving at the 1968 Olympics in Mexico City.
