Owjng to the thin-ness of the underlying clay, the roof has to be shot down tomake passage way in the entries. About a mile east of Mayview, on the Chicago and Altonrailway, is the Strasburg shaft. This is 90 ft. deep and herethe following section was measured: Feet. Section at May-TievT. Incliea. 1911. Limestone. Shale, black, fissile. Coal. Fartin Coal. Clay, hard, dark. Clay, soft, drab.
