Second Line. Miami Canal.

Ohio has constructed another canal, which, starting from Cincinnati on the Ohio, runs north to Dayton, and is called the Miami canal. It is 65 miles in length, and cost nearly 1,000,000 dollars, or 15,400 dollars a mile. By the aid of a grant of land from Congress, and the State’s resources, its prolongation is now in progress to Defiance, on the river Maumee, the site of a fortress of that name built by Gen. Wayne after his celebrated victory over the Indians. The Maumee, which was called by the French the Miami of the Lakes, is one of the principal tributaries of Lake Erie, and is to be canalled by the State. The distance from Dayton to Defiance is 125 miles; estimated cost 2,750,000 dollars, or 22,000 dollars per mile.
