According to Warington Smyth the reserves of 7 or 8 of theLean Mines amount to about 984 million tons of raw stone;more recent statistics however indicate the figure for calcinedstone at 658 million tons or 940 million tons of raw stone. Of the four blackbands the upper three are usually worked andcalcined together, namely the Halfyards, the Red Shagg- and theRed Mine. The approximate thicknesses in feet of the RedMines and the Bassey Mine are given in the following table, thelocalities in the west being given on the left, tbose on the northin the centre, and those in the south on the rig-ht.

Mwp showing a^^oximate contours in Feet below O.D. in the Bed Mine and the Bassey Mine; key map furnished by Blate 7, NOETH STAFFORDSHIRE. 67 The Bassey Mine Ironstone was well developed in the easternpart of the coalfield and was worked opencast from Shelton north-ward by the east of Burslem and Tunstall round the synclineto Broadfield and the faulted area beyond. It covers a muchgreater area than that of the Eed Mines, for it persists many milesfurther south, and although its limit in that direction is unknownit has been proved in several boreholes to maintain its quality. Onthe east near Newstead Farm, about half-a-mile south-east ofTrentham Station, it was found at a depth of 1,946 ft. and wasthere a foot thick. Near Hanchurch, nearly 3 miles to the west,it has also been proved, but not west of this. An east and westline may provisionally be accepted about a mile south of theseplaces as the southern limit of the area of reserves. Allowancemust be made for the probability of the ir
