In my last blog, “That danged blue stuff” I told you a bit about the silver found near Virginia City, Nevada. Well, mining silver and mining gold are two different things. Gold is found in hard Quartz, and relatively near the surface, whereas silver is in soft ore, deep underground, and large quantities of ore must be taken out, creating large “caverns”. So cave-ins were very frequent. and many lost their lives. It was a man named Philip Deidesheimer who came up with the solution. Copying Bee cells, he designed small wooden structures stacked on top of each other, thus they could be roofed and floored and so protect the miners.
