'The Whirlpool', 1872. Churning waters near Niagara Falls, USA: '...the Whirlpool and its rapids...are more than a mile below the falls, and the best point of observation is from the American side...[It] is not exactly a whirlpool. It is a vast and furious eddy, which, meeting with a very faint resistance from the shale and gravel of the hills at that precise point, cuts out, by its force, a huge, semicircular curve, and would, no doubt, have cut its way, but was suddenly arrested by hard rocks, which forced it to make a sudden turn to the right hand'.
