not more than 4 feet of rock between them, and the middle 

 and top seams are generally about 7 feet apart. The coal 

 is worked by the pillar-and-stall system, from two level 

 entries, which have been driven about 2,000 feet. The 

 beds in the mine workings, dip to the east at angles ranging 

 from 24 to 40 . 



A 500 pound sample from each of these seams taken 

 by the writer in 1908 was treated and analysed by the 

 Mines Branch, — the following being part of the results 

 of this work.*
