Question: Which was a longer canal, the Indiana Central Canal or the Louisville and Portland Canal?

<P0-S0> The Indiana Canal Company was a corporation first established in 1805 for the purpose of building a canal around the Falls of the Ohio on the Indiana side of the Ohio River. <P0-S1>  After several attempts, and possible sabotage by a supporter of the Louisville and Portland Canal, the project was ended. <SEP> <P1-S0>  The Falls form the only barrier to navigation between the origin of the Ohio at Pittsburgh and the port of New Orleans on the Gulf of Mexico; circumventing them was long a goal for Pennsylvanian and Cincinnatian merchants. <P1-S1> The Louisville and Portland Canal was a 2 mi canal bypassing the Falls of the Ohio River at Louisville, Kentucky. <P1-S2>  The canal opened in 1830 as the private Louisville and Portland Canal Company but was gradually bought out during the 19th century by the federal government, which had invested heavily in its construction, maintenance, and improvement. <P1-S3>  The Louisville and Portland Canal became the McAlpine Locks and Dam in 1962 after extensive modernization. <SEP> <P2-S0>  It was funded by the Mammoth Internal Improvement Act, Indiana's attempt to take part in the canal-building craze, started by the Erie Canal. <P2-S1>  $3.5 million was allocated for the project, the largest piece of the entire $10 million Act. <P2-S2> The Indiana Central Canal was a canal intended to connect the Wabash and Erie Canal to the Ohio River. <P2-S3>  However, due to the Panic of 1837, Indiana suffered financial difficulties and had to turn over the canal to the state's creditors, and building of the canal was stopped in 1839. <P2-S4>  The canal was supposed to extend 296 mi , from Peru, Indiana, to Evansville, Indiana, where it would reach the Ohio River. <P2-S5>  It was originally divided into two sections, North and South. <P2-S6>  Later, a third section was designated, called the Indianapolis section. <P2-S7>  Only eight miles were completed, with eighty additional miles between Anderson, Indiana, and Martinsville, Indiana, having been partially built. <SEP> <P3-S0> Observatory Inlet is an inlet on the North Coast of British Columbia. <P3-S1>  It is a northward extension of Portland Inlet, other sidewaters of which include the Portland Canal. <P3-S2>  The entrance of Observatory Inlet, from Portland Inlet, lies between Ramsden Point and Nass Point. <P3-S3>  Ramsden Point also marks, to the west, the entrance of Portland Canal. <P3-S4>  Observatory Inlet was named by George Vancouver in 1793, because he set up his observatory on the shore of the inlet, at Salmon Cove, in order to calibrate his chronometers. <P3-S5>  His two vessels, HMS "Discovery" and HMS "Chatham", stayed in Salmon Cove from July 23 to August 17, 1793. <P3-S6>  During this time a boat surveying expedition under Vancouver himself explored Behm Canal. <P3-S7>  Vancouver also named three headlands at the entrance of Observatory Inlet: Maskelyne Point, for Nevil Maskelyne, the Astronomer Royal, Wales Point, for William Wales, the mathematical master who sailed with James Cook, and Ramsden Point, after the famed mathematical instrument-maker Jesse Ramsden.
