Gen. Johnston's Confederate Line of Defense

General Johnston's Confederate Line of Defense - January, 1982;  Between
Columbus and Cumberland Gap just over 50,000 Confederate troops opposed
just under 90,000 Federals.  The geographic factors facing Johnston included
the two rivers; Cumberland and the Tennessee.  Between these two water
passages deep into the Confederacy, he had statoned Gen. Tilghman with his
engineering skill at Fort Henry and Fort Donelson.  Consequently, both
Clarkesville and Nashville were threatened, the former being the site of the
Cumberland Iron works, second only to Richmond's Tredegar in iron output.

Great Granby Salmon Arch

The Great Salmon Arch was the culvert and aqueduct over Salmon
Brook in Granby, CT as a part of the Farmington Canal.  The span
of the arch was to be 40 feet.  This arch is of particular interest as
the present (third) span was the third to be constructed, the first two
arches being lost in past seasonal floods.  Reference: Forty-Ninth
