Thank you All,
    I received at least a dozen helpful messages directing me to Thomas =
Cole's
=22The Course of Empire=22 series (1836-1838).  I was able to view them =
on-line,
verify that they indeed were the paintings that I remembered, and locate =
slides
on campus to use in class.  You also provided me with a number of citations =
that
will help better equip me to discuss the paintings with students.

With Gratitude,
