If anyone is an expert on Twain's whereabouts in New York, I would like 
to determine exactly where the Manhattan Wharf, that the Quaker City 
departed from in 1867, is located.  There are plenty of maps of old New 
York docks but none that I know of that identify this particular dock.  
I would like to get a precise location for my maps.
