580 COAL. 



It is a good thick coal in most of this region, varying from 4 

 to 12 feet, but usually has several slate partings that reduce 

 its value greatly. The analyses available show that the coal 

 is somewhat high in ash, but very low in sulphur, averaging 

 less than one per cent., and also low in phosphorus, making 

 it suitable for metallurgical coke or gas manufacture. Care- 

 ful mining methods must be used to separate the slates but 

 the thickness of the seam would permit most of this refuse to 

 be thrown aside without removing it from the mine. Its out- 

 crop is shown on Map II and the probable minable area on 

 Figure 11.

A sample was collected from Nos. 4, 6 and 8 of section, 

 the composition of which is given under Mine No. 256 in the 

 table of coal analyses at the end of this Chapter. 



The Frank Crawford Farm Mine (No. 257 on Map II), on 

 Glady Creek, 0.9 mile north of Bablin, shows the coal 3' 11" 

 thick, the basal portion being concealed, and the elevation 

 being 1255' B., as shown by the section for Bablin, on page 72.
