Terry--
Did Tom Thatcher give you a copy of the Scientific American article as well? We also have a copy of Porter's book with his account of the Greyhound.
And, of course, our section on TEC and his friends can be found here: http://www.civilwarstlouis.com/boatburners/index.htm
You might particularly like "Hell and Maria".
Best. Geo Rule www.civilwarstlouis.com
