This letter describing the travel from Connecticut to Iowa is probably the first letter sent from Grinnell, IA, to Meriden, CT. It seems to fix the arrival of George and Electa in Grinnell to late April 1857.
The letter seems to be a fragment. The first paragraph discusses the where the writer lives, and details of the surrounding area. The second paragraph discusses information concerning state government and jurisdiction districts. Also mentioned is the State University [later University of Iowa].
