NOVA SCOTIA COALS AND OTHER MINERALS — GILPIN. 25 



Some years ago, in a paper read before the Montreal meeting 

 of the British Association for the advancement of Science, I 

 gave the average composition of the coals of the Cumberland 

 coal held as folllows : 



Moisture 1-46 



Volatile combustible matter 83.09 



Fixed carbon 59.35 



Ash 5.50 



100.00 



From this it will be seen that the seams of coal represented 

 by the analyses given in this paper compare favorably with the 

 average. 



9. Magnetic Iron Ore, from Kemptville. 



Metallic iron 58.20 



Silicious matter 11.50 



Sulphur and Phosphorus Traces. 



The ore is said to occur in a vein three feet wide. 



10. Sample of Red Hematite from Greener Mine, George's River, 



Cape Breton County. 

 Vein said to be from six to nine feet wide, and is situated on 

 high ground, near deep water on the Bras D'or Lake. As will 

 be seen from this analysis, the ore is of excellent quality. The 

 rock in which it is found is, I Ijelieve, of Lower Silurian age. 

 The slates, etc., composing this horizon are in this locality very 

 full of finely disseminated peroxide of iron. 



Moisture 1.10 



L'on oxide 89.30 



Silicious and clayey matter 7.82 



Lime 67 



Magnesia 88 



Phosphoric Acid 20 



Sulphur Trace. 



99.97
