Frederick MD\, Senior Center DESCRIPTION:Before the C&\;O Canal\, before the B&\;O Railroad\, betw een 1785 and 1828 over 200\,000 tons of freight\, mostly grain\, was shipp ed down the Potomac River to Georgetown and out to a hungry world. This wa s the accomplishment of George  Washington’s Potomac Company\, establis hed in 1785 to “get the rocks out of the way” and allow for in-river n avigation of the Potomac River. This lecture will allow you to see the Pot omac River system through the eyes of our first President. It will review the technologies used to “open up” the Potomac revealing the successes and failures of the project. Perhaps most interesting\, we will explore t he 200-year-old ruins the project left behind for us to admire such as the Great Falls canal.\n\nOur speaker is Paul Kreingold the Conservation Dire ctor of the Loudoun County Chapter of the Izaak Walton League\, Virginia M aster Naturalist and author of Potomac Marble: The History of the Search f or the Ideal Stone.
