Canal injured by Confederates, August 1864.
Chesapeake & Ohio Canal. - This great public work was injured by the late Confederate raids to such an incalculable extent that it is almost impossible to tell when navigation will be resumed. It appears that at the lower end of the Canal they took especial pains to do as much damage as possible. The aqueduct at the mouth of the Antietam was very materially damaged by throwing off the heavy stone walls which form the trunk, and boring holes through the archway. Lock No. 40 was also considerably injured by the walls having been excavated and thrown in.
