Which canal's cargo was primarily coal, the Cape Cod Canal or the Chesapeake and Ohio Canal?
Chesapeake and Ohio Canal The Chesapeake and Ohio Canal, abbreviated as the C&O Canal and occasionally called the "Grand Old Ditch," operated from 1831 until 1924 along the Potomac River from Washington, D.C., to Cumberland, Maryland. The canal's principal cargo was coal from the Allegheny Mountains.
Nutbrook Canal The Nutbrook Canal was a canal in England which ran between Shipley in Derbyshire and the Erewash Canal, joining it near Trowell. It was built to serve the collieries at Shipley and West Hallam, and was completed in 1796. It was initially profitable, but from 1846 faced competition from the railways, and more seriously, subsidence caused by the coal mines that it was built to serve. With the mines failing to pay tolls for goods carried on the canal, and in some cases refusing to accept responsibility for the subsidence, most of it was closed in 1895, although the final 1.5 mi remained in use until 1949.
