"The coal yields a bulky ash of a reddish brown color. It has not 

 the slightest tendency to form a coherent coke, and yields volatile matters 

 burning with a non-luminous flame. The water was estimated at 223°, and 

 upon withdrawal of the heat the coal begins to absorb water with great 

 avidity. So that in two hours it has re-absorbed sixty-three per cent, of the 

 amount of water originally present." 



Throwing out the water, sulphur and ash, the proportion stands : 



Fixed Carbon 80.003 



Volatile Hydrocarbons 19.907 



100.000 



Volatile Hydrocarbons to Fixed Carbon, as 1 to 4.023. 



No. 2. Coal sixty feet below bottom of Bed B, at Bernice, Sullivan 

 county, Pennsylvania. 



The coal is for the most part coated with iron oxide and infiltrated silt. 

 It has a dull dead lustre, and is compact and brittle, with very irregular 

 fracture. The coal does not have the slightest tendency to coke and yields 

 gases which burn with a very feebly luminous flame. After cooling (water 

 estimation) the coal immediately begins to absorb water and in two hours 

 has re-absorbed about sixty per cent, of the water originally present. 



Water 5.815 



Volatile Matter 15.083 



Fixed Carbon 62.329 



Sulphur 474 



Ash 16.297 



Color of ash, reddish grey. 



100.000 



Leaving out the accidental impurities, and counting only the ignitible 

 constituents, the proportion stands : 



Fixed Carbon 80.514 



Volatile Hydrocarbons 19.486 



100.000 

 Volatile Matters to Fixed Carbon as 1 to 4.132. 



It should be noted that this coal specimen was necessarily taken from 

 near the outcrop, which accounts for the oxide of iron coating, the infil- 

 trated silt, and in part for the high percentage of ash. 



A second specimen of this same coal (sixty feet below bed B at Bernice) 

 taken from under better cover, w T as also analyzed by Mr. McCreath. 



"The coal does not coke, and the gases burn with a very feebly lumin- 

 ous flame. The coal, after being dried, begins to absorb water rapidly, 

 and in two hours has re-absorbed sixty per cent, of the water originally 

 present. This amount is not increased by longer exposure.
