There is an entry in the list of speeches page
for this Twain-Cable speaking engagement.  I can find no other reference
nor any information about the named venue. This particular event is not
included in the listing at the University of Virginia site.  I've tried
the Newark Historical Society and local libraries to no avail.  Orange
is rather a difficult location to research as it seems there are really
four of them: North, South, East and West. Unlike Newark, they don't
seem to have an historical society.

I would like to include this venue in my Twain Gazetteer, if possible.
It's not possible for me to do any serious researching so I do what I
can and ask Twain-L.

Thanks, Scott
