Packs of Dogs Hound Middleburg

Packs of dogs, most of them German shepherds, have been chasing and attacking farm animals in the Middleburg area since late December, according to Mayor Loyal McMillan. Farm managers in the area report that the dogs have killed cows, sheep and goats and have even chased full-grown horses. "They wear collars and seem well fed and are not afraid of

A spokesman for the animal control office said that dogs act differently in a group than they do individually. "A domestic dog considers himself part of a human pack," she said. "When a dog is with a lot of other dogs, that changes." McMillan said that one farm manager is willing to set up a lookout station for officials or news reporters who want to see the dogs in action, usually before dawn. It is legal to shoot dogs caught in the act of killing or injuring livestock in Loudoun, and some have already been killed by angry farmers. "But no one is bragging about it," McMillan said. If a dog is wearing tags that identify its owner, the farm owner could sue for losses, he said. Hillsboro Pipeline Bid Revised

The engineering firm of Dewberry and Davis last week submitted a revised bid of $9,500 for construction of a new water pipe through Hillsboro, according to town clerk Elna Gripp. In addition, a Culpeper firm has submitted its own bid of $8,700 to do the job, she said.

The Town Council, which may apply for a state communty block grant to pay for the work, decided not to vote on the issue until its Feb. 11 meeting. "They might want to hold a public hearing on it," Gripp said. "Some residents might not want to get the town in debt and would support a grant. Others might be against it." Since water for the town of Hillsboro is supplied by a spring, developers have not shown an interest in the 125-resident town, which is just the way they want it, officials say. Officials are also considering setting up an architectural review board to protect the town's historic flavor. Round Hill Advertises for Bids

Round Hill officials advertised for bids to engineering firms for the replacement of 85 percent of its in-town water lines and the selection process will begin this month, according to Mayor Jeff Wolford.

Town officials met late last month with officials of the state Housing and Community Development department in Richmond to explain the project and learn how the $700,000 grant the town received for the project will be administered. The contract with the state will be signed next month, Wolford said. The town will pay for part of the project with $105,500 from its own budget. Purcellville Hires Pastor Part Time

Purcellville recently hired Stanley Bailey, a Hamilton minister, as a part-time police officer, according to Town Manager William Dennis. Bailey's function will be to fill in for full-time officers on vacation, during illnesses and on weekends. "We're looking forward to having Mr. Bailey with us," Dennis said. "He has a wonderful attitude that will be good for the town."

On Feb, 20, officials will review preliminary site plans for 256 apartments on Rte. 722 near the Loudoun Valley High School. In the months ahead, Dennis said, developers will also discuss possible plans for single-family homes, duplexes and town houses with Purcellville officials. Developers have shown an increased interest in the town of 1,600 residents since construction of a $1.2 million water treatment plant began in August. However, there are currently only 10 water hookups available and officials are discussing how residential growth will affect the quality of Purcellville's water as well as its tax base, Dennis said. Loudoun Offers CPR Courses

Training in cardiopulmonary resuscitation will be offered at several locations in Loudoun County by the county's Citizens CPR program. Sponsored by Loudoun's Department of Fire and Rescue Services, the training will be available on Feb. 22 at 9 a.m. at the Sterling Rescue Squad headquarters.

On March 11 it will be offered at 7:30 p.m. at the Middleburg fire department and on March 21 at 7:30 p.m. at the Hamilton volunteer rescue squad headquarters. "We want to increase the number of people who know this life-saving technique," said county spokesman Howard Dawley, "and we hope to increase membership in the volunteer fire and rescue squads. We hope this training will wet their whistles for more." For information call 771-9553. Manassas Park Cougars Climb

The Manassas Park High School varsity basektball team is ranked third in the state, according to School Superintendent Jimmy Stuart. The Cougars are two-thirds through their schedule, Stuart said, and have beaten nearly every school they've played, including some Triple A teams.

The team, all juniors, have been coached since the eighth grade by former Prince William County schoolteacher Chip Miller. "Of course, some of the toughest games are ahead of us," Stuart said, "but we're real proud of them so far." Manassas Park, Virginia's smallest city, has fewer than 1,500 students. Occoquan Slates Hearing

Occoquan residents may be invited to comment on the town's revised comprehensive plan some time this month, according to Vice Mayor Andy Lynn. There will be no major land use changes in the plan; its function is to better define the land uses established when the plan was written more than five years ago, he said.

The plan is currently under review by the Planning Commission headed by chairman June Randolph. The Town Council is expected to set a public hearing date for the plan at its Feb. 11 meeting. Haymarket Hires Police Officer

Haymarket, which has been without a police officer since town Sgt. Don Fasick resigned in October, last week hired former George Mason University security guard Amos Damron, according to Mayor Gertrude Bean. Damron, 38, "comes from a long line of police officers," Bean said. He is expected to be on the beat by Feb. 15.

The Prince William Bond Referendum Citizens Committee will hold its second meeting for residents at 7:30 p.m. today in the old Board of Supervisors chamber on Lee Avenue in Manassas. Chairman Terry Spellane said the purpose is to learn residents' views as to which capital facilities, including roads, they feel the county should fund. Respondents to a recent committee survey overwhelmingly considered roads the most important county issue. For information call Julie Phillips at 335-6830.

Beginning today the Prince William County assessments offices will have later closing times on Thursdays only. The revised Thursday hours are 8:30 a.m. to 6:30 p.m. at the new county building on Davis Ford Road and 10:30 a.m. to 6:30 p.m. at the Manassas office. All other weekdays both offices will be open from 8:30 a.m. to 5:30 p.m. The change was made, a spokesman said, because so many residents are unable to get to the offices during regular business hours.
