12 II GEOLOGICAL SURVEY OP CANADA. 



dais— contained a good deal of iron pyrites, also occasional thin bright 



coBtf SeS ° ' lamina? of graphitic-looking matter. 



The weight of the sample received was fifty pounds, the whole 

 of this was reduced to powder and intimately mixed, in order to 

 obtain a fair average sample ; a portion of this was taken, and 

 afforded by slow and fast coking the following results : 



Slow coking. Fast coking. 



Hygroscopic water . . . : 3.73 3.73 



Volatile combustible matter. 28.01 34.33 



Fixed carbon 54.28 47.96 



Ash.... 13.98 13.98 



100. 100. 



Coke 68.26 61.94 



Ratio of volatile combustible matter 



to fixed carbon ... 1 : 1.94 1 : 1.40 



By rapid heating a bright and tolerably firm coke was obtained. 

 Colour of the ash purplish-grey. This coal very closely resembles 

 a sample of coal brought by Mr. Scott Barlow from the " Styles 

 Mine." 



2. — Lignite. — The locality of its occurrence is stated to be thirty miles 

 west of Fort McLeod, — near the base of the Eocky Mountains, four 

 miles south of Pincher Creek, Old Man's Eiver ; within a quarter 

 of a mile of an Indian farmer's house, — North West Territory. 



Colour pure black; structure somewhat lamellar; lustre shining 

 resinous, with occasional dull patches ; powder black, the same 

 communicated a deep brownish-red colour to a boiling solution of 

 caustic potash. 



Analysis by slow and fast coking gave : 



Slow coking Fast coking. 



Hygroscopic water 6.26 6.26 



Volatile combustible matter 29.31 31.96 



Fixed carbon 55.70 53.05 



Ash....... 8.73 8.73 



100. 100. 



Both slow and fast coking gave a pulverulent coke. The ash 

 had a pale reddish-brown colour and agglutinated slightly at a 

 bright red heat. 



3. — Eeceived through Dr. G-. M. Dawson from Charles Horetzky, Esq., — 

 the specimen was labelled " Skeena, Station 37, nine miles above the 

 Forks," — British Columbia.
