TheGalena limestone, or lead-bearing rock, occupies a consid-erable area in Northern Illinois and Iowa, and SouthernWisconsin. Its position is between the Hudson rivergroup and the Trenton limestone, and the lead depositsare restricted within that range. The present product ofthe mines is from 12,000 to 15,000 tons per annum, valuedat from $1,500,000 to $2,000,000.
