The original rock was surmounted by an enormous boulder, much smaller at its base than at the top, and balanced perfectly on the present rock. It was on this top boulder that Thomas Jefferson carved his name. In 1800, when he was Republican Candidate for President, one Captain Henry, of the United States Army detachment stationed at Harpers Ferry, ordered some of his men to accompany him to the Rock, and with crowbars and rams pushed the delicately balanced boulder bearing Jefferson's name off the pedestal and down the hill.
