NEW MINERAL DISCOVERIES IN NOVA SCOTIA.—GILPIN. 81 
120 Ibs., of tar. The ammonia liquor is distilled with milk of 
lime, and furnishes a shipping ammonia liquor with 17 per cent 
ammonia. The tar is available for distillation for creasote, 
pitch, ete. 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, 74.26 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 :—
