This is a really good book, but it's probably not for the general reader. Written in 1942, the author grew up in Virginia City and has a good, clear, skeptical writing style. He also has great lumps of detail on 1870s-era mining technology that will have a very narrow audience (at best). Pages and pages on stock-market manipulations too. I mean, who cares? Not me. The latter brings to mind Mark Twain's definition of a mine: "A hole in the ground with a liar at the top".
I suppose that mining guys (like me) who read fast and skim the dull parts, will enjoy it. Parts are great, parts very, very dull. Caveat lector!
