HALIFAX The foghorn at the Chebucto Head Lighthouse in Nova Scotia’s Halifax Harbour has been warning seafarers of pending danger since 1892. But it went silent in February and the Canadian Coast Guard says it has no plans to fix it, at least for now. Chebucto Head Lighthouse is a popular place for a walk. Bruce and Danuta Erskine go there a few times a week. The sound of that foghorn is the Maritimes, says Bruce Erskine. Yes, it s such a soothing sound, says Danuta Erskine. It s a sound, however, that hasn t been heard since needed repairs were deemed unnecessary by the Canadian Coast guard, leaving the marine warning signal - silent.
