Some account and description of Ithiel Town's improvement in the construction
Subtitle: and practical execution of bridges, aqueducts and rail road bridges, whether built entirely of wood, or of cast or wrought iron; being intended as a general system of bridge building, over rivers, creeks, harbors, or other places where bridges are necessary ...  Economy of expense, permanence and durability, united in a general system of building bridges, aqueducts, &c. suited to any part of the country, and which may be constructed of such materials as any part of the country will afford, are what is here attempted.  If these objects have been accomplished, they are important to the country; whether they have been accomplished is left for the country to decide.
