I have upgraded my site from drupal 7 to drupal 8. This was a m
ajor change in system architecture. I believe most of the original
paths remain the same but some links may be broken, for any of you that
have links to my original site. I have removed the logic for operating
as an on-line course. It remains a reference site for the travels of
Samuel L. Clemens, aka Mark Twain. The emphasis is on observing social
and physical phenomena related to the on-set of industrialization. One
major improvement is the inclusion of more maps. This is best seen in
parts of the section on the Twain-Cable Tour. Drupal mapping modules
have advanced to the point where I can display the train routes
followed by these "Twins of Genius". Such maps on the earlier version
of this site were screen captures of Google Earth displays.
There are more things in heaven and earth, Horatio, than are dreamt of
in your philosophy.
