3. Coal from Mabou, Inverness County. 



This coal was regarded as an Anthracite. I am not aware of 

 the aofe of the rocks it occurs in. Color black, and lustrous. 

 Breaks with uneven fracture into irregular shaped pieces. In 

 the fire kindles slowly, and Imrns without flame, yielding a fair 

 heat. The ashes left is white, and retains the shape of the orig- 

 inal piece as put on the fire. 



On analysis, it yielded : 



Volatile matter 2.73 



Fixed Carbon 43.71 



Ash 53.56 



Sulphur Trace. 



100.00 



From its composition and its behaviour in the fire, it may be 

 classified as a highl}^ carbonaceous shale. 



A similar mineral found at Lepreaux, near St. John, New 

 Brunswick, was analysed by me some ^^ears ago, and proved to 

 contain an amount of ash nearly ecpial to that of the Mabou 

 sample. As the percentage of ash in an ordinary connnercial
