A week or so ago there were several questions about mines in Jefferson Co. Last evening I was looking through The Report, a quarterly of The Ohio Genealogical Society. In the Winter 1995 issue on page 183 there is an article that mentions a publication The Annual Report of the Chief Inspector of Mines to the Governor of the State of Ohio for the year ending December 31,_____. I quote from the article "I have the 36th report for 1910. Therefore, if they published each year, the first report must have been about 1874." Further " It is another good source for all the mines in the state of Ohio. They are listed by county. A list of accidents; name(s) of those killed, nationality and age, cause of accident,...name of owner of mine, village where mine is located, number of empolyees including the name of the supt. with his address, results of inspections,..." This article does not list the mines, but it points the way. This appears to be a document of the state of Ohio. It should be in larger libraries in Ohio and perhaps could have pages photocopied for those unable to visit a library which owns this. Often government documents do not appear in the library catalog, but are separately cataloged and house in a government documents section. It is always best to write, call, or ask in person if you are not locating a government document. Certainly this would be held by The State Library of Ohio. Colleges that teach mining engineering should also have this. Hope this is helpful to some of you.
