NEW MINERAL DISCOVERIES IN NOVA SCOTIA. GILPIN. 81 



120 lbs.,of tar. The ammonia liquor is distilled with milk of 

 lirne, and furnishes a shipping ammonia liquor with 17 per cent 

 ammonia. The tar is available for distillation for creasote, 

 pitch, etc. Finally the coke, forming 75 per cent of the coking 

 charge, is available as a very excellent fuel. No doubt these 

 results will be improved on. 



More interesting information is given by a test made of the 

 Harbor seam at the Glassport, Pa., ovens of the United Coke 

 and Gas Company* The coal used in these ovens was run of 

 mine from the Upper Youghiogheny River, with the following 

 composition : Moisture, 60 ; fixed carbon, 59.18 ; volatile matter, 

 33.01; ash, 7.21; phosphorus, .0071 ; total sulphur, 1.27. The 

 resulting coke, 74.2G per cent, had the following composition : 

 Volatile matter, 1.00; carbon, 86.47; ash, 11.57; sulphur, .96 ; 

 phosphorus, .0107. A. net ton furnishes 10,000 cubic feet of gas, 

 of which 70 per cent is used for heating the ovens, and the 

 remainder is piped to steel works. 



The coal from the Harbor seam was slack, washed in Cape 

 Breton, and at the time of coking contained as much as 9 per 

 cent of moisture, as the cars stood for some months exposed to 

 winter weather. As under normal conditions this percentage 

 would be very much less, allowances should be made for 

 purposes of comparison. 



An average of several analyses gave the following as the 

 composition of the coal : 



Carbon 75.10 



Hydrogen 3.75 



Nitrogen 1.51 



Oxygen, Sulphur 13.80 



Ash . 5.84
