PONTIAC, Mich. (AP) _ The 15-year-old son of Polish labor leader and Nobel Peace Prize winner Lech Walesa has visited a local school as part of a three-month tour of the United States to improve his English.

During the visit to the Orchard Lake Schools, Slawek Walesa attended a workshop on Polish heritage.

Walesa, son of the founder of the banned Solidarity labor movement, arrived from Poland on Tuesday for a tour of the country with Jan Wydro, a Walesa family friend who lives in Oil City, Pa. Stops on Walesa's itinerary include Disney World in Orlando, Fla., New York City, and Washington, D.C., before returning home on Aug. 29.

''He just wants to see America,'' Wydro said. The large number of automobiles and computers in the United States has made the biggest impression on young Walesa, he said.

DELHI, N.Y. (AP) - Former pop singer Cat Stevens told delegates to the weekend annual convention of the Islamic Circle of North America that he's glad he got out of the music business.

Stevens, now known as Yousuf Islam, converted to Islam nine years ago after a successful career that included such hits as ''Wild World,'' 'Peace Train,'' ''Morning Has Broken,'' ''Oh Very Young'' and ''Another Saturday Night.''

In a lecture Saturday, the 40-year-old former singer-songwriter condemned the music industry, calling it corrupt, particularly in the business area. He said he was happy to have ''extracted'' himself from ''that business.''

The convention at the State University of New York College of Technology at Delhi ran Friday through Monday.

SAN FRANCISCO (AP) - Famed ''King of Torts'' lawyer Melvin Belli says he can't talk about his wife's filing for legal separation, but says he's written a book about marriage and divorce.

Lia Belli, 39, said Friday she had filed for the separation after 16 years of marriage and wanted Belli barred from their home. She contends the 80-year- old man beat her and falsely accused her of having affairs.

She is Belli's fifth wife. He said his book about marriage will be out in about three weeks.

Interviewed Saturday by a KCBS radio reporter outside the couple's mansion, Belli said one thing he's learned about marital disputes is that ''you don't talk about divorce when children are involved.''

The Bellis have one daughter, Melia, born in 1973.

Belli cut short a tour of the Soviet Union after Lia reported to police Tuesday that an intruder fired two shots at her in her bedroom at 5 a.m.

LEBANON, Tenn. (AP) - Gilligan, the Skipper and the rest of the gang won't be there, but Dawn Wells, better known as Mary Ann, will be in town Saturday as honorary queen of a ''Back to the '50s'' parade.

''I think it's a hoot,'' said Wells, who played Mary Ann on ''Gilligan's Island,'' the saga of seven castaways shipwrecked on a tropical island.

Ms. Wells said she doesn't mind being remembered as the shy, innocent girl- next-door she played on the 1960s sitcom that is still seen in reruns.

''People ask me trivia questions I can't answer,'' she said. ''I got on a plane recently and the whole plane broke out in the Gilligan's song. It's really nice to be recognized.''

Since the series, she has worked in television and on stage and appeared in the movies ''The Town That Dreaded Sundown'' and ''Winterhawk.''
