upwards of 500 feet above the level of the plains. The 

 seam measures from 11 to 12 feet in thickness, with 

 some subordinate layers of clay included. The quality 

 of the mineral is that of cannel or splent coal : it is hard 

 and compact, with a dull greyish-black lustre, plentifully 

 interveined with a splendent, shining black, bituminous, 

 and jet-] ike matter : its fracture is flat and flat conchoidal : 

 it ignites very readily, and burns without fusing, giving 

 out long jets of bright white flame : it yields a powerful 

 heat, and leaves a white slaty cinder, which ultimately 

 passes into light flocculent ashes. 



The seam dips to W.S.W. and W, by S., at the rate 

 of 1 in 17 or 18. 



The coal occurs in massive beds of soft greyish-white 

 sandstone, which alternate with clay-schist, replete with 

 impressions of leaves, &c. of plants. Under the seam 

 there is schistose clay, succeeded by a few inches of a very 

 hard coal, which merges in black shale, resting again 

 upon clay-schist with vegetable impressions. 



The following is the measurement of the different 



members composing the seam ; viz, —
