Came in from work tonight & my wife did a wonderful thing. She taped an episode of the Nova science series, on channel 9 (PBS) for me. It was titled "Lincoln's Secret Weapon" A report about the Monitor & the Navy raising the screw section of the craft. Check your local listings on the PBS station in your area & try to catch this, it was worth watching. Mine usually shows the episode a few times throughout the week at different time frames.
