Parrott round found in Maine river

Two men diving in the Piscataqua River in Maine recently uncovered an explosive find: an intact 100-pound Parrott artillery shell from the Civil War era. There was a gun carriage factory nearby and the shell may have fallen off the deck of a vessel transporting weapons. Or it could have been a "dud" fired from Fort Sullivan on the Portsmouth Naval Shipyard, just across the New Hampshire border. • Article
