100 HOW ON ANALYSIS OF TWO SPRING HILL COALS. 



II. Rapid Coking. 



Total volatile matters 35.65 



Fixed carbon 59.90 



Ash 4.45 



100.00 



Theoretical evaporative power 8.23 lbs. 



Coke, per cent 64.35 



For the sake of comparison the following analysis by E. Hartley,. 

 Esq., Geological Survey of Canada, may be given, and if compared 

 with II. shows the permanent character of this coal : 



11' 3" seam. 



Total volatile matters 35.39 



Fixed carbon 60.46 



Ash 4.15 



100.00 



Theoretical evaporative power. 8.37 lbs. (Prof. How.) 



Coke 64.60 



Sulphur 2.25 



This coal breaks with cubical fracture, and for various reasons 

 is very valuable, although its being tender causes a considerable 

 amount of loss to the company by the formation of slack coal. The 

 volatile matter is of such quantity and quality as to recommend this 

 coal in the preparation of gas. It cokes freely with small increase 

 of volume, giving a coherent, compact coke. The amount of 

 sulphur is remarkably small, an important fact as regards domestic 

 use, gas-making and preservation of grate-bars. The ash is gray- 

 ish-white and bulky. 



This company can export about 400 tons daily, from the wharf 

 at Dorchester, N. B. The coal is held in high favour by all who 

 have used it for domestic purposes.
