The shales are in some places remarkably bent and ontorted, as if by lateral pressure when in a soft state. A part of one of these flexures is accurately r" in Fig. 64, and illustrates some appearances in the mine to be subsequently noticed. '⢠The principal shaft has been sunk perpendicularly from the outcrop of the coal, and at its bottom is sixty-seven feet south of it The gallery connecting the bottom of the shaft with the coal shows thin-bedded bituminous shales with calcareous and ironstone bands and concretions, dipping at tlie end nearest the coal , at an angle of 60°, though a dip to the is more prevalent along this side of the mine. The coal at this place is about ten feet in thickness, and its upper surface dips about 75°. On the , or under side, it rests against tliv edges of the somewhat contorted beds already noticed as dipping to the southward, and on the north-west side it is overlaid by similar bods dipping in the same direction with tlic coal, but so much contorted as to ])vesent on the small scale a most complicated and confused appearance. The coal itself, as seen in mass underground, presientH a beautiful and .'lingular appearance. It has a splendent resinou? lu-jire and perfect conchoida! fracture ; it is perfectly free from mineral charcoal and lines of impure coal or earthy matter. It is, however, divided into prismatic pieces by a great number of smooth divisional jdanes, proceeding from wall to wall, much in the
