It will be seen that the Sulphur and Ash are extremely high, and 

 only in one instance (III. Taylor Place Bituminous) can the North 

 Carolina coal compare with the Tennessee analysis, having a some- 

 what higher percentage of each. 



It is also noticeable that the weight of a cubic yard of Tennessee 

 coal is in round numbers equivalent to a long ton, while those of 

 North Carolina, owing to the presence of a larger per cent of ash, 

 is somewhat more. 



The existence of Sulphur I consider to be almost entirely due to 

 the presence of iron pyrites. Oftentimes large glistening scales of 

 pyrites can be seen when the coal is fractured. Besides this visible 

 demonstration, analysis confirms this opinion, which is shown by the 

 following table:

Or in other words a sample of coal yields 3.69 per cent, of Sul- 

 phur and has 7.01 per cent, of Ash (a very low percentage); if all 

 the sulphur present were combined with iron it would give a per 

 centaare of 6.93 of pyrites (FeSg) which in burning would give off
