Join us next Tuesday, September 8 at 7:00PM for our FREE lecture “Lebanon County in the American Revolution” by Jack McClain at Freeman Hall at Cornwall Manor or on Zoom. Although far from the major battlefields of the American Revolution, the region that is now Lebanon County played a vital role in supporting the fight for independence. This presentation explores how local communities helped sustain the Revolutionary War effort from 1776 to 1783.

Registration is only required for online attendance. To register for the virtual lecture, please go to: https://us02web.zoom.us/webinar/register/WN_i1w2Vx-LQWuHZAVJt8wifA #/registration

This tally board located in the Charging Room was likely used by workers to keep track of their charges. After every charge, they moved the peg down a spot. When they got to about 30 charges, then it was time to tap the furnace, which likely occurred around noon and midnight each day.
