Copper mining was revived along Lake Superior about 1842 and made a sudden jump. The California gold fever of 1849 was the beginning of the search and procurement of that metal on a considerable scale. Petroleum came prominently into notice for the first time in August 1859, when the Drake Well struck oil; and the Comstock Lode was discovered in Nevada that same year, and laid the foundation ...
