The above coals vary greatly in composition and in heating power, 
jnd it seems likely that in this field, as everywhere, each seam will be 
bund to have a characteristic composition. 
If these analyses are grouped and each group averaged they become 
tore significant. Samples 1, 6, 7, and 9 were all taken by the writer 
om four different seams in a somewhat restricted area. The range of 
ariation in this group is small, all being extremely pure as regards 
>oth ash and sulphur, and all have a fairly high content of fixed car- 
ion with a low content of volatile hydrocarbons and consequently 
jjairly high fuel ratio and heating value.
