Different kinds of Coal. There are many varieties of coal, 

 the three chief ones being : 1. Steam coal, or Welsh coal, or 

 Anthracite (from the Greek anthrax, charcoal). This is a very 

 hard coal, containing only a small proportion of bitumen. It 

 gives out great heat, and burns without smoke or flame. The 

 ships of the navy are coaled with it, our supplies being obtained 

 from the South Wales Coalfield. 



2. Bituminous coal contains bitumen, or pitch, and is softer 

 than anthracite, and lights more easily. It produces flame 

 and smoke.
