STOW IT: The boating lobby BOAT/U.S. reminds mariners that the Independence Day holiday is the nation's deadliest on the water, with up to 60 deaths likely to occur in boating accidents. Statistics show that more boating fatalities are caused by operator error than any other factor and that alcohol is involved in up to half of all boating deaths. The obvious conclusion: Don't drink while boating.

BALDY: Maryland's bald eagle nesting survey turned up record numbers again this year. Researchers counted 260 nesting pairs, up from a record 232 last year, and at least 368 young nestlings. Top county was Dorchester, as usual, with 58 pairs; Charles County was next with 37. Folks in Frederick County saw their first nesting pair since 1967. There were only 41 nesting pairs statewide in 1977, when the Department of Natural Resources started its surveys. Scientists blamed the pesticide DDT for the decline.
