The composition of the untouched lower part of the seam in the Bye 

 pit is ajiparently as follows : 



Volatile combustible matter 25 • 8 to 30 • 4 



Fixed carbon 54-8toG7-4 



Ash from 8-7 to 23-3 



as condensed from a number of analyses. 



The following analysis b}^ the writer, from a paper on the com- 

 position of Canadian Coals, of the ujjper portion of the Main seam, as 

 worked at the Forest pit, shows its improvement in quality toward the 

 dip : 



Moisture 1 -Oo 



Volatile combustible matter 26-19 



Fixed carbon (j3 • 41 



Ash 9-35 



The same rule appears to hold good in the case of the lower jjortion 

 of the seam ; as in the Foord pit district the ash in the lower part is 

 stated by the present agent of the lessees, to be eleven per cent against 

 an average of about sixteen per cent nearer the outcrop. The coal of the 

 Deep seam was very similar to the upper portion of the Main seam but 

 had a slightl}' greater percentage of ash. 



As to the coal contents of the Main seam forming the scene of the 

 operations more specially noted, the writer has been unable to procure 

 exact figures of the tonnage of coal extracted, as the returns at the dis-
