Along Big river, below the crossing of the Iron Mountain railway, and principally on the northern side, are a number of mines for a distance of some 10 miles from the railway. Prominent among these are the Mammoth and Frumet, from which is derived the name of the group. Gray's mines here were worked probably before 1830. The Mammoth mines were opened in 1843, and in tbe next 7 years yielded 2,500 tons of ore. The Frissel mines of this group were discovered in 1842. Work at the Frumet mines was not begun before the early seventies. These deposits all occur in magnesian limestone, and are in many respects similar to those last described. A few of the openings have been worked during past years, and some of these were visited by the writer.
