EXAMINATION AND ANALYSIS OF SEVERAL COALS AND 

 IRON ORES, ACCOMPANYING MR R. C. TAYLOR'S ACCOUNT 

 OF THE COAL FIELD OF BLOSSBURG. By T. G. Clemson, 

 Esquire. 



No. 1. 



Clements^ s Coal^ Bear creek, Blosshurg. 



This combustible is jet black, with a wax-like lustre ; 

 is formed of parallel layers ; is fragile, the fragments 

 assuming a trapezoidal form ; is not entirely free from 

 pyrites 5 the sulphate of iron showing itself in efflor- 

 escence. Its powder is black, with a shade of brown. 

 When submitted to heat, gives off bitumen, &c., leaving 

 a coke not much swollen, hard, and rather difficult to 

 pulverize. When incinerated, leaves an ash of a dirty 

 white, free from lime.

Coal from Bloss vein. Bear creek. 



This coal has a very great resemblance to that which 

 we have just examined (No. 1). What we have said of 

 its mineralogical history, is applicable to this.
