Book Description
Excerpt from The Copper Mines of Lake Superior Copper mining on Lake Superior commenced in 1845, about twenty-eight years since. Prior to this date copper had been Obtained throughout the world in the form of sulphuret. The discoveries 'of Lake Superior were of native copper, which was a novelty in copper mining, and so improbable, according to all geological precedents, that much doubt was expressed by scientific men in regard to its reality. The facts were, however, abundantly proven. The distribution of this native copper, which seemed such a geological wonder, was principally in masses of various weight barrel work, which is strung together in adhering rock, like roots of a tree in the soil, and stamp stuff, which is disseminated through the copper bearing rock in small particles, known among miners as shot copper. In these three forms the native copper of Lake Superior is distributed. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
