I have a chance to go next Tuesday to the Sate Archives in Harrisburg
and look through PCC records from 1838 to 1871. There are 42 cu. Ft.
of records for this lot.

I know some of the contents are Field Survey books. Which I hope
would shed some light on the Gravity RR exact layout.

I will also be looking at several lots of Photographs from the era.

My question is? What else should I be looking for or what else would
be of interest to anybody? I just don't want to say when I come back
doooh that was the book I was looking for.

So just let me know.
