to that of the best Welsh steam coals. It may be remarked that 

 the best American and Welsh coals would be classified as free

I also give here an analysis of the Patrick seam as worked 

 on the Patrick Lease, now the property of the Canada Coals and 

 Railway Company, on the west bank of the Macan River. The 

 sample is from the lower part of the seam : 



Moisture ... TOO 



Volatile Combustible Matter 55'61 



Fixed Carbon 35'60 



Ash 7'49 



Sulphur .... , t . *50 



As reddish and pulverulent. 



The following analyses of pit waters may be given here : 



Vale Colliery : 



Water contained in 1000 parts. 



Sulphate of Lime '514 



Magnesia '100 



Silicious matter '190 



Chloride of Sodium T452 



Carbonate of Sodium 7'509 



Iron and Alumnina Trace. 



Organic matter Trace. 



No free acid. 



Springhill, from feeder 1300 feet level, water clear, free from 

 smell, slightly acid : 



Sulphuric Acid, free Trace. 



Sulphate of Lime Large. 



Magnesia Small. 



Chloride of Sodium Considerable. 



Carbonic Acid Small. 



Carbonate of Lime Small. 



Iron Oxides . Small. 



Water exerted slightly corrosive action on iron exposed to it 

 for twenty-four hours. 



A number of analyses of Nova Scotia mineral and pit waters 

 are given in a paper by the writer, read before the Newcastle 

 Mining Institute some years ago.
