*The Loudoun County summer job match program in Leesburg is again open for business. Coordinator Ruth Hatfield said the program, which attempts to match youths with employers, hopes to place qualified young people in a variety of jobs, including sales, clerical, food services, farm and cashier positions. Homeowners can also hire participants, who range in age from 11 to 21, for chores such as painting, yardwork and babysitting. "As a result of interest and cooperation from local employers last year, we were able to place 187 young people in private sector jobs," Hatfield said.

Employers may call Hatfield at (703) 777-0358 or toll-free from Washington at 478-1850, extension 358, between 9 a.m. and 5 p.m. Young people looking for jobs may also call those numbers or come to the office at 115 Harrison St. to fill out a registration card.

*Figures released by the Loudoun County Department of Tourism indicate that the new Market Station, a $5 million shopping and restaurant complex two blocks from Leesburg's historic downtown, has been instrumental in drawing 2,800 more tourists to the town than visited last year.

According to Tourism Director Hugh Harmon, the Loudoun Museum drew 2,033 tourists last month and Market Station attracted more than 3,000. In April 1985, the total number of visitors to the museum was 2,313.

Market Station, which opened last month, is a complex of antique shops, boutiques and restaurants, five of which are located in 19th century buildings rebuilt and moved to the site by developer Bruce Brownell.

In another development, officials announced that long-awaited signs directing tourists to Leesburg have been erected by the State Highway Department at the four entrances to the town. The signs can now be seen on Rte. 15 north and south and Rte. 7 east and west.

*Broad Run High School's marching concert band recently captured two top awards at the Wildwood (N.J.) High School Music Festival, band Director George Philip said.

The 98-student band, which has also won prizes in the Baltimore Thanksgiving Day Parade and in local Halloween and Columbus Day parades, was judged the winner in the concert division and came in third in the parade competition.

The group competed against 20 high school bands, many of which came from larger schools, Philip said. The band did not participate in the Grand Champion Award competition at Wildwood because the students would have had to miss school to attend the four-day event. "The students understand that academics come first," he said.
