hughes: KURHTJRBAEf COAL T'lELD. 



Taking the average of the above table as 16 feet^ and multiplying 

 by 81 square miles^ we reduce the amount of coal to 1_,360 milUons 

 of tons. 



If we wish however to arrive at an estimate of the available coal, 

 we have to consider collectively the size of the seam, the dip, the quality 

 of the coal, and the eifect of faults, dykes, and other troubles. 



This next table gives the thicknesses of the coals at every place men- 

 tioned in the memoir, and by excluding the non-workable seams we 

 shall be able to judge fairly what the field may be reasonably expected 

 to yield.

The dip of these seains is too 

 high for working economically. 

 The thickness of the 10' 0" seam is 

 stated approximately.

These thicknesses are averages, and 

 are fairer estimates than assuming 

 the greatest thickness of each 

 seam.
