| Lake Superior in Michigans Iron country 1800's
But to revert to the point from which we digressed in making a brief
statement concerning the Jackson, Cleveland and Lake Superior mines. For
several years these were the only mines opened, and they are still called the
"three old mines." They have been continuously productive for more than
twenty-five years and two of them show more ore in sight than at any other
period in their history. Up to the close of last season the Jackson mine
had shipped in the aggregate 2,446,421 tons of ore; the Cleveland, 3,024,-
972, and the Lake Superior mine, 3,368,560 tons. The total manufacture
and shipment of pig iron during the same period up to the close of 1884,
was nearly one million and one hundred thousand gross tons.
