Copper mines and mining
Two papers were read in 1880, by Prof. Winchell, on the ancient copper mines of Isle Royale. After an account of the exterior phenomena of the mines, and an enumeration of the articles found in them, an inquiry was instituted as to the race that wrought them, and as to their relation to the Mound Builders, and to the Indians. As it has been admitted for several years that the Lake Superior miners were identical with the Mound Builders, the inquiry involved the examination of the relation of the Mound Builder to the present Indian. The characteristics of the Mound Builders were stated, as determined by the highest archaeological authorities, and compared with those known to be possessed by the aborigines.
