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.

Book Description
Excerpt from Copper Mining in Lake Superior There is a very generally received opinion that the copper in these beds occurs in Shoots. This does not appear to be proved, though the opinion seems to have some foundation from the experience of the Calumet Hecla Mine, where a body Of poor rock has been left.

Book Description
Excerpt from Pre-Columbian Copper Mining in North America The yield of mounds, graves and fields, as shown in the col lections, confirms in a general way the observations of the first discoverers. In the eastern and southern parts of the country the majority of the copper articles which have been found are breastplates, bracelets, beads, bobbin-like objects and other orna ments, while in the north and west, and especially in Wisconsin, implements and weapons prevail. The Wisconsin specimens are like those figured by Whittlesey (smithsonian Contributions, XIII), which were found in the mining district itself, and those found at Brockville, Canada, and shown in Wilson's Prehistoric Man. Others, apparently of the same character, are mentioned by Wilson as being found near Marquette, Michigan, east of the copper district.
