List are from my own Database. I've put down the list as an alphabetic one, and not by the arbitrary ID number - the first 337 of those ID numbers is from a 1903-ish map from the USGS showing the location of mines & mills, and after that I've just added new numbers as I find some info or other reasons I find a new entity, and have the need to keep track of them.
