Damage to the C&O Canal, Aug 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 digging holes through the arch way. Lock No. 40 was also considerably injured by the walls having been excavated and thrown in. The original materials of those works, however, consisting of dressed blocks, will be lifted by derricks from the depths below and again put in place, and thus the work will be more speedily reconstructed than otherwise would be the case. The damage done to the other locks is confined to the destruction of the wooden gates.
