104 EXPLANATION OF PLATE 66. 



the Coal fields of the northern and central parts 

 of England shall be exhausted.^ 

 Fio-. 3. Section of inclined Carboniferous strata, over- 



o 



laid unconformably by horizontal strata of New 

 Red Sandstone, Lias, and Oolite, in Somersetshire. 



This Section illustrates the manner in which Car- 

 boniferous strata have been elevated at their extre- 

 mities around the circumference of a basin, and 

 depressed towards its centre, and also intersected 

 by fractures or Faults. See V. I. pp. 527, 542. 



In Section 1, 2, of this Plate, no notice is taken 

 of the Faults which intersect the Coal basins.

 Pt. 3, PI. XXI. XXII. XXIII.f The advantages 



* The lower and richest beds of this Coal district are not only 

 raised to the surface, and rendered easily accessible around the ex- 

 ternal margin of the basin, but are also brought within reach in 

 consequence of another important elevation, along an anticlinal line, 

 running nearly E. and W. through a considerable portion of the in- 

 terior of the basin, in the direction of its longer diameter. 



t I feel it a public duty to make known an act of Mr. Buddie, 

 which will entitle hira to the gratitude of posterity, and has set an 

 example, which, if generally followed in all extensive collieries, will 

 save the lives of thousands of unfortunate miners, that must other- 

 wise perish for want of information which can, at this time, be easily 

 recorded for their preservation. This eminent Engineer and Coal 

 Viewer has presented to the Natural History Society of Newcastle,
