There's article in The Workingman's Advocate, Philadelphia, PA 26/07/1873 (page 4) which is a letter sent to the paper from a miner in Nvesville, Rockville Parke County, Indiana. In it he refers to a previous letter he has sent. I've tried various different search terms but can't seem to find anything, although I realise it possible his previous letter was never published.
Can anyone see anything?
Thanks
Jay
