Washington has the sixth-best manners of any city in the United States, according to the tabulations of etiquette expert Marjabelle Young Stewart.

Stewart yesterday announced her third annual list of the nation's 10 best-mannered cities, based on her own cross-country travels and a poll of about 100 service industry workers such as taxi drivers and restaurant owners. Charleston, S.C., rated first.

"Charleston was the runaway winner," Stewart said. "It's a city of great tradition and charm. There is a real gentleness in the community, and they really make tourists feel welcome."

Other cities placing ahead of the nation's capital were Seattle, Oklahoma City, Detroit and Minneapolis. Philadelphia, New York City, Kansas City, Mo., and Pasadena, Calif., rounded out the list.

Stewart is the author of 15 books on etiquette and a frequent television talk-show guest.

Wolff Joins St. Paul Chamber Orchestra

Conductor Hugh Wolff, a Washington native who began his career with the National Symphony, has been named principal conductor of the prestigious St. Paul Chamber Orchestra. His appointment, in a reorganization following the resignation of former music director Pinchas Zukerman, will make him part of a three-person team directing the orchestra. Sharing responsibility with Wolff will be Christopher Hogwood, with the title of director of music, and composer John Adams, with the title of creative chair. Wolff will conduct the orchestra for six weeks per season, work with Hogwood in developing artistic policies and take responsibility for the overall quality of the orchestra. His appointment is for three years, and he will keep his position as music director of the New Jersey Symphony Orchestra.

Rep. Marilyn Lloyd of Tennessee is recuperating from surgery to repair a detached retina, a hospital spokesman in Chattanooga, Tenn., said yesterday. Lloyd, who was in good condition after the two-hour operation Sunday at Erlanger Medical Center, is expected to go home today.

Hospital spokesman Davis Lundy said Lloyd is expected to spend two to three weeks recovering but doctors won't know the ultimate outcome of the surgery for at least six months.

She said her decision was not connected to her health.

A New Look at CBN

Former "Dallas" star Susan Howard helped the Christian Broadcasting Network unveil a new $60,000 peach-and-aqua studio set Monday for its popular "700 Club" program. Howard, who played Donna Krebbs on the nighttime soap for seven years, will serve as cohost of the CBN show along with Ben Kinchlow and Tim Robertson, whose father, the Rev. Pat Robertson, left the show to consider a 1988 run for the White House. Tim Robertson hopes the show's new format will attract viewers turned off to TV evangelism by the downfall of PTL's Jim and Tammy Bakker.
