The mineral statistics for 1866 have been published this week,

and show that we last year produced 101,630,000 tons of coal, or three and a half millions more than last year ; 4,530,000 tons of iron, of which more than a tithe was exported; 15,080 tons of tin, or a reduc- tion of about 600 tons ; 180,398 tons of copper, 67,181 tons of lead, and 724,856 ounces of silver. The total value of all the minerals raised was about 41,712,000/., or considerably less than that of- the harvest. It is, however, in much fewer hands.
